Warning: Risks From Concomitant Use With Opioids
- Concomitant use of benzodiazepines and opioids may result in profound sedation, respiratory depression, coma, and death [see Warnings and Precautions (5.1), Drug Interactions (7.2)].Reserve concomitant prescribing of these drugs for use in patients for whom alternative treatment options are inadequate.Limit dosages and durations to the minimum required.Follow patients for signs and symptoms of respiratory depression and sedation.
1 Indications And Usage
NAYZILAM is indicated for the acute treatment of intermittent, stereotypic episodes of frequent seizure activity (i.e., seizure clusters, acute repetitive seizures) that are distinct from a patient's usual seizure pattern in patients with epilepsy 12 years of age and older.
2.1 Instructions Prior To Dosing
NAYZILAM prescribers should consider the following prior to initiation of treatment:For patients at increased risk of respiratory depression from benzodiazepines, administration of NAYZILAM under healthcare professional supervision should be considered prior to treatment with NAYZILAM; this administration may be performed in the absence of a seizure episode [see Warnings and Precautions (5.2)].Prior to treatment, the healthcare professional should instruct the individual administering NAYZILAM on how to identify seizure clusters and use the product appropriately [see Patient Counseling Information: Administration Information (17)]. Patients and caregivers should be counseled to read carefully the "Instructions for Use" for complete directions on how to properly administer NAYZILAM.
2.2 Dosage Information
Administer NAYZILAM by the nasal route only.
Initial Dose: Administer one spray (5 mg dose) into one nostril.
Second Dose (if needed): One additional spray (5 mg dose) into the opposite nostril may be administered after 10 minutes if the patient has not responded to the initial dose.A second dose of NAYZILAM should not be administered if the patient has trouble breathing or if there is excessive sedation that is uncharacteristic of the patient during a seizure cluster episode [see Warnings and Precautions (5.2)].
Maximum Dosage and Treatment Frequency: Do not use more than 2 doses of NAYZILAM to treat a single episode. It is recommended that NAYZILAM be used to treat no more than one episode every three days and no more than 5 episodes per month [see Drug Abuse and Dependence (9.4)].
Risks from Concomitant Use with Other CNS DepressantsThe potential for an increased CNS-depressant effect from concomitant use with alcohol or other CNS depressants (e.g., opioids) must be considered by the prescribing physician, and appropriate recommendations made to the patient and/or caregiver [see Warnings and Precautions (5.1) and Drug Abuse and Dependence (9.3)].Concomitant use of barbiturates, alcohol, or other CNS depressants may increase the risk of hypoventilation, airway obstruction, desaturation, or apnea and may contribute to profound and/or prolonged drug effect [see Drug Interactions (7.3)].
Risks from Concomitant Use with Moderate or Strong CYP3A4 InhibitorsThere is a potential for prolonged sedation from concomitant use with moderate or strong CYP3A4 enzyme inhibitors because of much higher midazolam exposures [see Drug Interactions (7.2) and Clinical Pharmacology (12.2)].
Pregnancy Exposure RegistryThere is a pregnancy exposure registry that monitors pregnancy outcomes in women exposed to antiepileptic drugs (AEDs), such as NAYZILAM, during pregnancy. Encourage women who are taking NAYZILAM during pregnancy to enroll in the North American Antiepileptic Drug (NAAED) pregnancy registry by calling 1-888-233-2334 or visiting http://www.aedpregnancyregistry.org/.
Risk SummaryThere are no adequate and well-controlled studies of NAYZILAM in pregnant women.Available data suggest that the class of benzodiazepines is not associated with marked increases in risk for congenital anomalies. Although some early epidemiological studies suggested a relationship between benzodiazepine drug use in pregnancy and congenital anomalies such as cleft lip and or palate, these studies had considerable limitations. More recently completed studies of benzodiazepine use in pregnancy have not consistently documented elevated risks for specific congenital anomalies. There is insufficient evidence to assess the effect of exposure to benzodiazepines during pregnancy on neurodevelopment.There are clinical considerations regarding exposure to benzodiazepines during the second and third trimesters of pregnancy or immediately prior to or during childbirth. These risks include decreased fetal movement and/or fetal heart rate variability, "floppy infant syndrome," dependence, and withdrawal (see Clinical Considerations and Human Data).Administration of midazolam to rats and rabbits during the period of organogenesis or to rats during late pregnancy and throughout lactation at doses greater than those used clinically did not result in any apparent adverse effects on development (see Animal Data). However, published data for midazolam and other benzodiazepines suggest the possibility of neuronal cell death and long-term effects on neurobehavioral and immunological function in animals following prenatal or early postnatal exposure at clinically relevant doses. NAYZILAM should be used during pregnancy only if the potential benefit to the mother justifies the potential risk to the fetus. Advise a pregnant woman and women of childbearing age of the potential risk to a fetus.In the U.S. general population, the estimated background risk of major birth defects and miscarriage in clinically recognized pregnancies is 2 to 4% and 15 to 20%, respectively. The background risk of major birth defects and miscarriage for the indicated population is unknown.
Fetal/Neonatal Adverse ReactionsInfants born to mothers who have taken benzodiazepines during the later stages of pregnancy can develop dependence, and subsequently withdrawal, during the postnatal period. Clinical manifestations of withdrawal or neonatal abstinence syndrome may include hypertonia, hyperreflexia, hypoventilation, irritability, tremors, diarrhea, and vomiting. These complications can appear shortly after delivery to 3 weeks after birth and persist from hours to several months depending on the degree of dependence and the pharmacokinetic profile of the benzodiazepine. Symptoms may be mild and transient or severe. Standard management for neonatal withdrawal syndrome has not yet been defined. Observe newborns who are exposed to NAYZILAM in utero during the later stages of pregnancy for symptoms of withdrawal and manage accordingly.
Labor and DeliveryAdministration of benzodiazepines immediately prior to or during childbirth can result in a floppy infant syndrome, which is characterized by lethargy, hypothermia, hypotonia, respiratory depression, and difficulty feeding. Floppy infant syndrome occurs mainly within the first hours after birth and may last up to 14 days. Observe exposed newborns for these symptoms and manage accordingly.
Congenital AnomaliesAlthough there are no adequate and well-controlled studies of NAYZILAM in pregnant women, there is information about benzodiazepines as a class. Dolovich et al. published a meta-analysis of 23 studies that examined the effects of benzodiazepine exposure during the first trimester of pregnancy. Eleven of the 23 studies included in the meta-analysis considered the use of chlordiazepoxide and diazepam and not other benzodiazepines. The authors considered case-control and cohort studies separately. The data from the cohort studies did not suggest an increased risk for major malformations (OR 0.90; 95% CI 0.61—1.35) or for oral cleft (OR 1.19; 95% CI 0.34—4.15). The data from the case-control studies suggested an association between benzodiazepines and major malformations (OR 3.01, 95% CI 1.32—6.84) and oral cleft (OR 1.79; 95% CI 1.13—2.82). The limitations of this meta-analysis included the small number of reports included in the analysis, and that most cases for analyses of both oral cleft and major malformations came from only three studies. A follow up to that meta-analysis included 3 new cohort studies that examined risk for major malformations and one study that considered cardiac malformations. The authors found no new studies with an outcome of oral clefts. After the addition of the new studies, the odds ratio for major malformations with first trimester exposure to benzodiazepines was 1.07 (95% CI 0.91—1.25).
Neonatal Withdrawal and Floppy Infant SyndromeNeonatal withdrawal syndrome and symptoms suggestive of floppy infant syndrome associated with administration of benzodiazepines during the later stages of pregnancy and peripartum period have been reported. Findings in published scientific literature suggest that the major neonatal side effects of benzodiazepines include sedation and dependence with withdrawal signs. Data from observational studies suggest that fetal exposure to benzodiazepines is associated with the neonatal adverse events of hypotonia, respiratory problems, hypoventilation, low Apgar score, and neonatal withdrawal syndrome.
Animal DataWhen midazolam (0, 0.2, 1, or 4 mg/kg/day) was administered intravenously to pregnant rats during the period of organogenesis, no adverse effects on embryofetal development were observed. The highest dose tested, which was associated with minimal evidence of maternal toxicity, is approximately 4 times the maximum recommended human dose (MRHD) of 10 mg based on body surface area (mg/m2).When midazolam (0, 0.2, 0.6, and 2 mg/kg/day) was administered intravenously to rabbits during the period of organogenesis, no adverse effects on embryofetal development were reported. The high dose, which was not associated with evidence of maternal toxicity, is approximately 4 times the MRHD on a mg/m2 basis.When midazolam (0, 0.2, 1, or 4 mg/kg/day) was administered intravenously to female rats during late gestation and throughout lactation, no clear adverse effects were noted in the offspring. The high dose, which was not associated with evidence of maternal toxicity, is approximately 4 times the MRHD on a mg/m2 basis.In published animal studies, administration of benzodiazepines, including midazolam, or other drugs that enhance GABAergic neurotransmission to neonatal rats has been reported to result in widespread apoptotic neurodegeneration in the developing brain at plasma concentrations relevant for seizure control in humans. The window of vulnerability to these changes in rats (postnatal days 0-14) includes a period of brain development corresponding to that taking place during the third trimester of pregnancy in humans.
Risk SummaryMidazolam is excreted in human milk. Studies assessing the effects of midazolam in the breastfed infant or on milk production/excretion have not been performed. Postmarketing experience suggests that breastfed infants of mothers taking benzodiazepines, such as NAYZILAM, may have effects of lethargy, somnolence, and poor sucking.The developmental and health benefits of breastfeeding should be considered along with the mother's clinical need for NAYZILAM and any potential adverse effects on the breastfed infant from midazolam or from the underlying maternal condition.
SymptomsThe manifestations of midazolam overdosage reported are similar to those observed with other benzodiazepines, including sedation, somnolence, confusion, impaired coordination, diminished reflexes, coma, and untoward effects on vital signs.
TreatmentTreatment of midazolam overdosage is the same as that followed for overdosage with other benzodiazepines. Respiration, pulse rate, and blood pressure should be monitored and general supportive measures should be employed. Attention should be given to the maintenance of a patent airway and support of ventilation, including administration of oxygen. An intravenous infusion should be started. Should hypotension develop, treatment may include intravenous fluid therapy, repositioning, judicious use of vasopressors appropriate to the clinical situation, if indicated, and other appropriate countermeasures. There is no information as to whether peritoneal dialysis, forced diuresis, or hemodialysis are of any value in the treatment of midazolam overdosage.Flumazenil, a specific benzodiazepine-receptor antagonist, is indicated for the complete or partial reversal of the sedative effects of benzodiazepines and may be used in situations when an overdose with NAYZILAM is known or suspected. There are anecdotal reports of adverse hemodynamic responses associated with midazolam following administration of flumazenil to pediatric patients. Prior to the administration of flumazenil, necessary measures should be instituted to secure the airway, assure adequate ventilation, and establish adequate intravenous access. The reversal of benzodiazepine effects may be associated with the onset of seizures in certain high-risk patients. The prescriber should be aware of a risk of seizure in association with flumazenil treatment, particularly in long-term benzodiazepine users. The administration of flumazenil in cases of benzodiazepine overdose can lead to withdrawal and adverse reactions, including increased seizures. Its use in patients with epilepsy is typically not recommended.
PharmacokineticsBased on a population pharmacokinetic analysis, plasma exposures (Cmax and AUC) of midazolam in epilepsy patients increase approximately proportional to dose from 5.0 mg to 15 mg, 0.5 and 1.5 times the recommended maximum total dose (5 mg Initial Dose + 5 mg Second Dose), respectively.
Absorption Following nasal administration of a single 5 mg midazolam dose to healthy adults, midazolam was absorbed with median Tmax (range) of 17.3 (7.8 to 28.2) minutes; midazolam mean (±SD) Cmax and AUC0-∞ were 54.7 (±30.4) ng/mL and 126.2 (±59) ng∙hr/mL, respectively. The mean absolute bioavailability is approximately 44%.
DistributionIn adults and pediatric patients, midazolam is approximately 97% bound to plasma protein, principally albumin. In healthy volunteers, 1-hydroxy midazolam is bound to the extent of 89%.The estimated total volume of distribution of midazolam is 226.5 L.In humans, midazolam has been shown to cross the placenta and enter into fetal circulation and has been detected in human milk and CSF [see Use in Specific Populations (8.1, 8.2)].
EliminationFollowing administration of NAYZILAM in clinical trials, median midazolam and 1-hydroxy-midazolam elimination half-lives ranged from 2.1 to 6.2 hours and 2.7 to 7.2 hours, respectively, independent of dose.
MetabolismMidazolam is primarily metabolized by liver and intestinal cytochrome P450 3A4 (CYP3A4) to its pharmacologic active metabolite, 1-hydroxy midazolam (also termed α-hydroxy-midazolam). Midazolam is also metabolized to two other minor metabolites: 4-hydroxy metabolite and 1,4-dihydroxy metabolite. The principal urinary excretion products are glucuronide conjugates of the hydroxylated derivatives.Studies of the intravenous administration of 1-hydroxy-midazolam in humans suggest that 1-hydroxy-midazolam is at least as potent as the parent compound and may contribute to the net pharmacologic activity of midazolam.
ExcretionThe principal urinary excretion product is 1-OH midazolam in the form of a glucuronide conjugate. Smaller amounts of the glucuronide conjugates of 4-hydroxy- and dihydroxy-midazolam are detected as well.
Geriatric PatientsIn a parallel group study of 2.5 mg and 5 mg doses of NAYZILAM, mean systemic exposure (AUC) and peak plasma concentrations (Cmax) of midazolam were 21 to 45% higher in geriatric subjects (> 65 years old) as compared to non-geriatric subjects. The terminal half-life was increased by approximately 2 hours in the geriatric subjects because of a decrease in clearance [see Use in Specific Populations (8.5)].
Obesity In a study comparing normal (n=20) and obese patients (n=20), the mean half-life of midazolam administered by parental route was greater in the obese group (5.9 versus 2.3 hours). This was because of an increase of approximately 50% in the volume of distribution (Vd) corrected for total body weight. The clearance was not significantly different between groups.
Patients with Renal ImpairmentPatients with renal impairment may have longer elimination half-lives for midazolam and its metabolites [see Use in Specific Populations (8.6)].Midazolam and 1-hydroxy-midazolam pharmacokinetics in 6 ICU patients who developed acute renal failure (ARF) were compared with a normal renal function control group. Midazolam was administered as an infusion (5 to 15 mg/hr). Midazolam clearance was reduced (1.9 vs 2.8 mL/min/kg) and the half-life was prolonged (7.6 vs 13 hours) in the ARF patients. The renal clearance of the 1-hydroxy-midazolam glucuronide was prolonged in the ARF group (4 vs 136 mL/min) and the half-life was prolonged (12 vs >25 hours). Plasma levels accumulated in all ARF patients to about ten times that of the parent drug. The relationship between accumulating metabolite levels and prolonged sedation is unclear. In a study of chronic renal failure patients (n=15) receiving a single intravenous dose of midazolam, there was a 2-fold increase in the clearance and volume of distribution, but the half-life remained unchanged.
Patients with Hepatic ImpairmentMidazolam pharmacokinetics were studied after an intravenous single dose (0.075 mg/kg) was administered to patients with biopsy proven alcoholic cirrhosis (n=7) and control patients (n=8). The mean half-life of midazolam increased 2.5-fold in the patients with cirrhosis. Clearance was reduced by 50% and the Vd increased by 20%. In another study in male patients with cirrhosis (n=21) without ascites and with normal kidney function as determined by creatinine clearance, no changes in the pharmacokinetics of midazolam or 1-hydroxy-midazolam were observed when compared to healthy individuals. The clinical significance of these findings is unknown.
Patients with Congestive Heart Failure In patients suffering from congestive heart failure, a 2-fold increase in the elimination half-life, a 25% decrease in the plasma clearance, and a 40% increase in the volume of distribution of midazolam were observed.
Drug Interaction StudiesSince NAYZILAM is metabolized by CYP3A4, interactions with drugs that inhibit or induce CYP3A4 are likely.
- Inhibitors of CYP3A4 IsozymesCoadministration of CYP3A4 inhibitors with NAYZILAM has not been studied. However, the effects of inhibitors on midazolam exposure following NAYZILAM administration are expected to be similar to those following IV midazolam administration. Concomitant use of CYP3A4 inhibitors may result in prolonged sedation because of a decrease in plasma clearance of midazolam [Warnings and Precautions (5.3) and Drug Interactions (7.1)].The effect of single oral doses of 800 mg cimetidine and 300 mg ranitidine on steady-state concentrations of oral midazolam was examined in a randomized crossover study (n=8). Cimetidine increased the mean midazolam steady-state concentration from 57 to 71 ng/mL. Ranitidine increased the mean steady-state concentration to 62 ng/mL. No change in choice reaction time or sedation index was detected after dosing with the H2 receptor antagonists.In a placebo-controlled study, erythromycin administered as a 500 mg dose, three times a day, for 1 week (n=6), reduced the clearance of midazolam following a single 0.5 mg/kg IV dose. The half-life was approximately doubled.The effects of diltiazem (60 mg three times a day) and verapamil (80 mg three times a day) on the pharmacokinetics and pharmacodynamics of midazolam were investigated in a three-way crossover study (n=9). The half-life of midazolam increased from 5 to 7 hours when midazolam was taken in conjunction with verapamil or diltiazem. No interaction was observed in healthy subjects between midazolam and nifedipine.In a placebo-controlled study, where saquinavir or placebo was administered orally as a 1200 mg dose three times a day for 5 days (n=12), a 56% reduction in the clearance of midazolam following a single 0.05 mg/kg IV dose was observed. The half-life was approximately doubled.
Inducers of CYP3A4 IsozymesExposures (e.g., combined Cmax or AUC of midazolam and the 1-OH-midazolam active metabolite) are decreased 16 to 26% when NAYZILAM is co-administered with anti-epileptic drugs that are strong CYP3A4 inducers (e.g., phenytoin, phenobarbital, primidone, carbamazepine). Exposures (e.g., combined Cmax or AUC of midazolam and the 1-OH-midazolam active metabolite) are decreased 8 to 15% when NAYZILAM is co-administered with anti-epileptic drugs that are weak to moderate CYP3A4 inducers (e.g., clobazam, eslicarbazepine, felbamate, oxcarbazepine, rufinamide, topiramate). These changes in exposures are not expected to be clinically significant.
CarcinogenesisMidazolam maleate was administered in the diet to mice and rats for 2 years at doses of 0, 1, 9, or 80 mg/kg/day. In female mice in the highest dose group there was a marked increase in the incidence of hepatic tumors. In high-dose male rats there was a small but statistically significant increase in benign thyroid follicular cell tumors. The highest dose not associated with increased tumor incidences in mice and rats (9 mg/kg/day) is approximately 4 and 9 times, respectively, the recommended human dose (RHD) of 10 mg based on body surface area (mg/m2). The pathogenesis of induction of these tumors is not known. These tumors were found after chronic administration, whereas human use will ordinarily be of single or several doses.
MutagenesisMidazolam was negative for genotoxicity in in vitro (Ames, mammalian cell clastogenicity) and in vivo (mouse bone marrow micronucleus) assays.
Impairment of FertilityWhen midazolam (0, 1, 4, or 16 mg/kg) was orally administered to male and female rats prior to and during mating and continuing in females throughout gestation and lactation, no adverse effects on male or female fertility were noted.
Risks from Concomitant Use with OpioidsInform patients and caregivers that potentially fatal additive effects may occur if NAYZILAM is used with opioids and not to use NAYZILAM concomitantly with opioids unless supervised by a healthcare provider. If a decision is made to prescribe NAYZILAM concomitantly with opioids, instruct caregivers to follow patients closely for signs and symptoms of respiratory depression and sedation [see Warnings and Precautions (5.1)].
Risks of Cardiorespiratory Adverse ReactionsWarn patients and caregivers about the risks of respiratory depression, cardiac and respiratory arrest [see Warnings and Precautions (5.2)].Advise caregivers on the signs and symptoms of respiratory depression to look for, how long to observe patients after administering NAYZILAM, the circumstances under which a second dose should not be given, and the circumstances under which emergency medical care should be summoned [see Dosage and Administration (2.1)].
CNS Depression from Concomitant Use with Other CNS DepressantsWarn patients and caregivers that the use of NAYZILAM in combination with alcohol or other CNS depressant drugs may increase the risk of hypoventilation, airway obstruction, desaturation, or apnea and may contribute to profound and/or prolonged drug effect [see Warnings and Precautions (5.3)].Caution patients against engaging in hazardous occupations requiring mental alertness, such as operating machinery, driving a motor vehicle or riding a bicycle until they have completely returned to their level of baseline functioning.
Suicidal Behavior and IdeationCounsel patients, their caregivers, and families that AEDs, including NAYZILAM, may increase the risk of suicidal thoughts and behavior and that they should be alert for the emergence or worsening of the signs and symptoms of depression, any unusual changes in mood or behavior or the emergence of suicidal thoughts, behavior or thoughts about self-harm. Behaviors of concern should be reported immediately to healthcare providers [see Warnings and Precautions (5.4)].
Impaired Cognitive FunctionWarn patients that midazolam, including NAYZILAM, is associated with a high incidence of partial or complete impairment of recall for the next several hours. Counsel patients on when they can engage in activities requiring complete mental alertness, operate hazardous machinery, or drive a motor vehicle after taking NAYZILAM [see Warnings and Precautions (5.5)].
PregnancyInstruct patients to inform their physician if they are pregnant or are planning to become pregnant. Several studies have suggested an increased risk of congenital malformations associated with the use of benzodiazepine drugs. Animal studies have demonstrated an effect on early brain development and long-term cognitive effects with exposure to anesthetic and sedation drugs in the third trimester of gestation. Encourage patients to enroll in the North American Antiepileptic Drug (NAAED) Pregnancy Registry if they become pregnant. The registry is collecting information about the safety of antiepileptic drugs during pregnancy [see Use in Specific Populations (8.1)].
LactationInstruct patients to inform their physicians if they are nursing [see Use in Specific Populations (8.2)].
Important Treatment InstructionsInstruct patients and caregivers on what is and is not an intermittent and stereotypic episode of increased seizure activity (i.e., seizure cluster) that is appropriate for treatment, and the timing of administration in relation to the onset of the episode.Instruct patients and caregivers on what to observe following administration, and what would constitute an outcome requiring immediate medical attention.Instruct patients and caregivers not to administer a second dose of NAYZILAM if they are concerned by the patient's breathing, the patient requires emergency rescue treatment with assisted breathing or intubation, or there is excessive sedation [see Dosage and Administration (2.1)].Advise patients and caregivers on how frequently they can treat successive seizure cluster episodes over time.
Administration InformationAdvise patients and caregivers to not open the blister packaging until ready to use. Instruct them to not test or prime before use and to not use if the nasal spray unit appears damaged.

3 Dosage Forms And Strengths
NAYZILAM is supplied as a single-dose nasal spray unit containing 5 mg of midazolam in 0.1 mL solution.
- NAYZILAM is contraindicated in patients with:Known hypersensitivity to midazolam.Acute narrow-angle glaucoma [see Warnings and Precautions (5.6)].
5.1 Risks From Concomitant Use With Opioids
Concomitant use of benzodiazepines, including NAYZILAM, and opioids may result in profound sedation, respiratory depression, coma, and death. Because of these risks, reserve concomitant prescribing of benzodiazepines and opioids for use in patients for whom alternative treatment options are inadequate.Observational studies have demonstrated that concomitant use of opioid analgesics and benzodiazepines increases the risk of drug-related mortality compared to use of opioids alone. If a decision is made to prescribe NAYZILAM concomitantly with opioids, prescribe the lowest effective dosages and minimum durations of concomitant use, and follow patients closely for signs and symptoms of respiratory depression and sedation. Advise both patients and caregivers about the risks of respiratory depression and sedation when NAYZILAM is used with opioids [see Drug Interactions (7.2)].
5.2 Risks Of Cardiorespiratory Adverse Reactions
Serious cardiorespiratory adverse reactions have occurred after administration of midazolam. These have included respiratory depression, airway obstruction, oxygen desaturation, apnea, respiratory arrest and/or cardiac arrest, sometimes resulting in death or permanent neurologic injury. There have also been rare reports of hypotensive episodes requiring treatment during or after diagnostic or surgical manipulations, particularly in patients with hemodynamic instability. Hypotension occurs more frequently in patients premedicated with a narcotic. The danger of hypoventilation, airway obstruction, or apnea is greater in elderly patients and those with chronic disease states or decreased pulmonary reserve [see Use in Specific Populations (8.5)]; patients with chronic obstructive pulmonary disease are highly sensitive to the respiratory depressant effect of midazolam.Respiratory depression was observed with the administration of NAYZILAM during clinical trials [see Adverse Reactions (6.1)]. Cardiac or respiratory arrest caused by NAYZILAM was not reported during clinical trials.
5.3 Central Nervous System Depression From Concomitant Use With Other Central Nervous System Depressants, Or Moderate Or Strong Cyp3a4 Inhibitors
Drug products containing midazolam, including NAYZILAM, have a central nervous system (CNS) depressant effect.
5.4 Suicidal Behavior And Ideation
Antiepileptic drugs (AEDs), including NAYZILAM, increase the risk of suicidal thoughts or behavior in patients taking these drugs for any indication. Patients treated with any AED for any indication should be monitored for the emergence or worsening of depression, suicidal thoughts or behavior, and/or any unusual changes in mood or behavior.Pooled analyses of 199 placebo-controlled clinical trials (mono- and adjunctive therapy) of 11 different AEDs showed that patients randomized to one of the AEDs had approximately twice the risk (adjusted Relative Risk 1.8, 95% CI:1.2, 2.7) of suicidal thinking or behavior compared to patients randomized to placebo. In these trials, which had a median treatment duration of 12 weeks, the estimated incidence rate of suicidal behavior or ideation among 27,863 AED-treated patients was 0.43%, compared to 0.24% among 16,029 placebo-treated patients, representing an increase of approximately one case of suicidal thinking or behavior for every 530 patients treated. There were four suicides in drug-treated patients in the trials and none in placebo-treated patients, but the number is too small to allow any conclusion about drug effect on suicide.The increased risk of suicidal thoughts or behavior with AEDs was observed as early as one week after starting drug treatment with AEDs and persisted for the duration of treatment assessed. Because most trials included in the analysis did not extend beyond 24 weeks, the risk of suicidal thoughts or behavior beyond 24 weeks could not be assessed. The risk of suicidal thoughts or behavior was generally consistent among drugs in the data analyzed. The finding of increased risk with AEDs of varying mechanisms of action and across a range of indications suggests that the risk applies to all AEDs used for any indication. The risk did not vary substantially by age (5-100 years) in the clinical trials analyzed. Table 1 shows absolute and relative risk by indication for all evaluated AEDs.Table 1. Risk by Indication for Antiepileptic Drugs in the Pooled AnalysisIndicationPlacebo Patients with Events/1000 PatientsDrug Patients with Events per 1000 PatientsRelative Risk: Incidence of Drug Events in Drug Patients /Incidence in Placebo PatientsRisk Difference: Additional Drug Patients with Events per 1000 PatientsEpilepsy1.03.43.52.4Psychiatric126.96.36.199.9Other1.01.81.90.9Total188.8.131.52.9The relative risk for suicidal thoughts or behavior was higher in clinical trials for epilepsy than in clinical trials for psychiatric or other conditions, but the absolute risk differences were similar for the epilepsy and psychiatric indications.Anyone considering prescribing midazolam or any other AED must balance the risk of suicidal thoughts or behaviors with the risk of untreated illness. Epilepsy and many other illnesses for which AEDs are prescribed are themselves associated with morbidity and mortality and an increased risk of suicidal thoughts and behavior. Should suicidal thoughts and behavior emerge during treatment, the prescriber needs to consider whether the emergence of these symptoms in any given patient may be related to the illness being treated.
5.5 Impaired Cognitive Function
Midazolam, including NAYZILAM, is associated with a high incidence of partial or complete impairment of recall for several hours following an administered dose. Gross tests of recovery from the effects of midazolam cannot be relied upon to predict reaction time under stress. It is recommended that no patient operate hazardous machinery or a motor vehicle until the effects of the drug, such as drowsiness, have subsided, and as their medical condition permits. For pediatric patients, particular care should be taken to ensure safe ambulation.
Benzodiazepines, including NAYZILAM, can increase intraocular pressure in patients with glaucoma. Measurements of intraocular pressure in patients without eye disease show a moderate lowering following induction with midazolam. NAYZILAM may be used in patients with open-angle glaucoma only if they are receiving appropriate therapy. Patients with open-angle glaucoma may need to have their ophthalmologic status evaluated following treatment with NAYZILAM. NAYZILAM is contraindicated in patients with narrow-angle glaucoma.
5.7 Other Adverse Reactions
When midazolam was used for sedation, reactions such as agitation, involuntary movements (including tonic/clonic movements and muscle tremor), hyperactivity, and combativeness have been reported. These reactions may be caused by inadequate or excessive dosing or improper administration of midazolam; however, consideration should be given to the possibility of cerebral hypoxia or true paradoxical reactions.

6.1 Clinical Trials Experience
Because clinical trials are conducted under widely varying conditions, adverse reaction rates observed in the clinical trials of a drug cannot be directly compared to rates in the clinical trials of another drug and may not reflect the rates observed in clinical practice.NAYZILAM was studied for the outpatient treatment of a single seizure cluster in 292 adult and adolescent patients with epilepsy (Study 1) [see Clinical Studies (14)]. The study was conducted in two phases; an open-label Test Dose Phase followed by a double-blind, placebo-controlled, Comparative Phase. The mean age of patients enrolled in the Comparative Phase (N=201) was 33 years, 51% were female, and 95% were White.Table 2 lists the adverse reactions occurring in 2% or more of the NAYZILAM-treated patients and at a rate greater than the placebo-treated patients in the Comparative Phase of Study 1.Table 2: Adverse ReactionsAdverse reactions that occurred within 2 days after NAYZILAM administration are included that Occurred in ≥2% of Patients (Any NAYZILAM) and Greater than Placebo in the Comparative Phase of Study 1Body System/Adverse ReactionPlaceboNAYZILAMPatients in Study 1 were permitted to take a second, open-label dose of NAYZILAM 5 mg between 10 minutes and 6 hours following the initial blinded dose of NAYZILAM 5 mg or placebo if they experience seizure recurrence or an incomplete resolution of the episode.

7 Drug Interactions
Table 3: Clinically Significant Drug Interactions With NAYZILAM7.1 CYP3A4 InhibitorsClinical Impact:Concomitant use of CYP3A4 inhibitors may result in prolonged sedation because of a decrease in plasma clearance of midazolam.Intervention:Avoid co-administration of NAYZILAM with moderate or strong CYP3A4 inhibitors. NAYZILAM should be used with caution when co-administered with mild CYP3A4 inhibitors.Examples:Moderate CYP3A4 inhibitors: erythromycin, diltiazem, verapamilStrong CYP3A4 inhibitors: ketoconazole, itraconazole, clarithromycin7.2 OpioidsClinical Impact:The concomitant use of benzodiazepines and opioids increases the risk of respiratory depression because of actions at different receptor sites in the CNS that control respiration. Benzodiazepines interact at GABAA sites and opioids interact primarily at mu receptors. When benzodiazepines and opioids are combined, the potential for benzodiazepines to significantly worsen opioid-related respiratory depression exists.Intervention:Reserve concomitant prescribing of these drugs for use in patients for whom alternative treatment options are inadequate. Limit dosages and durations to the minimum required [see Warnings and Precautions (5.1)].Examples:Morphine, hydrocodone, oxymorphone, codeine, fentanyl7.3 Other Central Nervous System (CNS) DepressantsClinical Impact:Concomitant use of barbiturates, alcohol, or other CNS depressants may increase the risk of hypoventilation, airway obstruction, desaturation, or apnea and may contribute to profound and/or prolonged drug effect.Intervention:Reserve concomitant prescribing of these drugs for use in patients for whom alternative treatment options are inadequate. Limit dosages and durations to the minimum required [see Warnings and Precautions (5.3)].Examples:Other benzodiazepines and sedatives/hypnotics, anxiolytics, tranquilizers, muscle relaxants, general anesthetics, antipsychotics, opioids, alcohol.
8.4 Pediatric Use
Safety and effectiveness of NAYZILAM have been evaluated in the age group 12 to 17 years. Use of NAYZILAM in this age group is supported by evidence from an adequate and well-controlled study of NAYZILAM in adults and adolescents with seizure clusters [see Clinical Studies (14)] and pharmacokinetic and safety data from adult and pediatric patients [see Clinical Pharmacology (12.3)].Safety and effectiveness in pediatric patients below the age of 12 years have not been established.
8.5 Geriatric Use
Safety and efficacy studies of NAYZILAM did not include sufficient numbers of subjects aged 65 and over to determine whether they respond differently from younger subjects. Geriatric patients have longer elimination half-lives for midazolam and its metabolites, which may result in prolonged drug exposure. Geriatric patients may have altered drug distribution; diminished hepatic and/or renal function; and subjects over 70 years of age may be particularly sensitive [see Clinical Pharmacology (12.3)]. Administration of intramuscular (IM) midazolam to elderly patients has been associated with rare reports of death under circumstances compatible with cardiorespiratory depression [see Warnings and Precautions (5.2)]. In most of these cases, the patients also received other CNS depressants capable of depressing respiration, especially narcotics [see Warnings and Precautions (5.1, 5.3)]. Close monitoring of geriatric patients is recommended.
8.6 Renal Impairment
Based on a population pharmacokinetic analysis of patients administered NAYZILAM, midazolam and 1-OH midazolam pharmacokinetics are expected to be similar in subjects with mild renal impairment when compared to normal subjects. Safety and efficacy studies of NAYZILAM did not include patients with severe renal impairment and there were not enough subjects with moderate renal impairment in clinical studies for population pharmacokinetic analysis. Patients with moderate and severe renal impairment may have slower elimination of midazolam and its metabolites, which may result in prolonged drug exposure [see Clinical Pharmacology (12.3)].
8.7 Congestive Heart Failure
Patients with congestive heart failure eliminate midazolam more slowly, which may result in prolonged drug exposure [see Clinical Pharmacology (12.3)].
9.1 Controlled Substance
NAYZILAM contains the benzodiazepine midazolam, a Schedule IV controlled substance under the Controlled Substances Act.
Benzodiazepines, such as midazolam, may be subject to abuse. Abuse is the intentional non-therapeutic use of a drug, even once, to achieve a desired psychological or physiological effect. Available data concerning the drug abuse and dependence potential of midazolam suggest that its abuse potential is at least equivalent to that of diazepam.The pharmacological profile of NAYZILAM is similar to that of other benzodiazepines listed in Schedule IV of the Controlled Substance Act, particularly in its potentiation of GABAergic transmission through its action on GABAA receptors, which leads to sedation and somnolence.Midazolam was actively self-administered in primate models used to assess the positive reinforcing effects of psychoactive drugs. Midazolam produced physical dependence of a mild to moderate intensity in cynomolgus monkeys after 5 to 10 weeks of administration.Assessment of the abuse-related subjective effects comparing NAYZILAM to oral midazolam syrup was conducted in adult subjects with a history of benzodiazepine recreational drug use. No statistically significant or clinically-relevant differences in subjective positive effects (i.e., Drug Liking, Overall Drug Liking, Take Drug Again, and High) were observed between NAYZILAM and oral midazolam syrup. However, subjective positive effects on all these measures were significantly greater for NAYZILAM than for placebo confirming that NAYZILAM has abuse potential. Somnolence occurred at a similar rate in both midazolam groups, but euphoric mood occurred at a greater rate in NAYZILAM (4 to 16%) compared to the oral midazolam syrup (4 to 8.5%).
Physical dependence is a state of adaptation that is manifested by a specific withdrawal syndrome that can be produced by abrupt cessation, rapid dose reduction, decreasing blood levels of the drug, and/or administration of an antagonist.Benzodiazepines can cause physical dependence. Physical dependence results in withdrawal symptoms in patients who abruptly discontinue the drug. Withdrawal symptoms (i.e., convulsions, hallucinations, tremors, abdominal and muscle cramps, vomiting, and sweating), similar in characteristics to those noted with barbiturates and alcohol, have occurred following abrupt discontinuation of midazolam following chronic administration.
9.4 Chronic Use
NAYZILAM is not recommended for chronic, daily use as an anticonvulsant because of the potential for development of tolerance to midazolam. In clinical trials, patients were treated with NAYZILAM no more frequently than every 3 days.Chronic daily use of benzodiazepines may increase the frequency and/or severity of tonic-clonic seizures, requiring an increase in the dosage of standard anticonvulsant medication. In such cases, abrupt withdrawal of chronic benzodiazepines may also be associated with a temporary increase in the frequency and/or severity of seizures.
NAYZILAM contains midazolam, a compound of the benzodiazepine class. Midazolam is chemically designated as 8-Chloro-6-(ο-fluorophenyl)-1-methyl-4H-imidazo[1,5-a][1,4]benzodiazepine, and it has the following structure:The empirical formula is C18H13ClFN3 representing a molecular weight of 325.8. Midazolam, USP is a white or yellowish, crystalline powder that is practically insoluble in water, soluble in methanol, and freely soluble in acetone and in alcohol.NAYZILAM nasal spray is a clear, colorless to yellowish colored liquid. Each single-dose NAYZILAM unit is for nasal administration and delivers 5 mg of midazolam in 0.1 mL of solution containing ethanol; PEG-6 methyl ether; polyethylene glycol 400; propylene glycol; and purified water.The pH range of solution is approximately 5.0 to 9.0.
12.1 Mechanism Of Action
The exact mechanism of action for midazolam is not fully understood, but it is thought to involve potentiation of GABAergic neurotransmission resulting from binding at the benzodiazepine site of the GABAA receptor.
The pharmacodynamic properties of midazolam and its metabolites, are similar to those of other benzodiazepines, including sedative, anxiolytic, amnestic, and hypnotic activities. The effects of midazolam on the CNS are dependent on the dose administered, the route of administration, and the presence or absence of other medications.Treatment with NAYZILAM was associated with effects on measures of sedation and measures of psychomotor performance [see Warnings and Precautions (5.3)]. Sedation and psychomotor impairment effects generally began to occur within 10 minutes post dose with peak effects observed within 30 minutes to 2 hours post dose. The pharmacodynamic effects generally returned to near baseline levels by 4 hours post-dose.
14 Clinical Studies
The effectiveness of NAYZILAM for the acute treatment of intermittent, stereotypic episodes of frequent seizure activity (i.e., seizure clusters, acute repetitive seizures) that are distinct from a patient's usual seizure pattern in patients with epilepsy 12 years of age and older was established in a randomized, double-blind, placebo-controlled trial (Study 1; NCT 01390220).Study 1 enrolled patients with epilepsy on a stable regimen of antiepileptic drugs who were identified by their physicians as having intermittent, stereotypic episodes of frequent seizure activity that were distinct from the patient's usual seizure pattern. Study 1 was conducted in two phases: an open-label Test Dose Phase followed by a randomized, double-blind, placebo-controlled, Comparative Phase. In the Test Dose Phase, tolerability was assessed in 292 patients who, in the absence of a seizure, received two 5 mg doses of NAYZILAM (10 mg total dosage) separated by 10 minutes. Patients were excluded from participation in the Comparative Phase if they failed to meet pre-defined blood pressure, heart rate, sedation, electrocardiogram, and peripheral oxygen saturation criteria.In the Comparative Phase, 201 patients treated a single seizure cluster episode in an outpatient setting with either a blinded dose of NAYZILAM 5 mg (134 patients) or placebo (67 patients). If the seizure activity persisted or recurred, patients in both groups had the option to receive a subsequent unblinded dose of NAYZILAM 5 mg to be used between 10 minutes and 6 hours after administration of the initial blinded dose of study drug. The primary efficacy endpoint for Study 1 was treatment success, defined as the termination of seizures within 10 minutes after the initial blinded dose of study drug and the absence of a recurrence of seizures within 6 hours of the initial blinded dose of study drug. A statistically significantly higher percentage of NAYZILAM-treated patients met the primary efficacy endpoint, as shown in Table 4.Table 4: Primary Endpoint Results: Treatment Success (Study 1) NAYZILAM(N=134)Placebo(N=67)Treatment success (%)53.734.395% CI(45.3, 62.2)(23.0, 45.7)p-value0.011Numerical differences in favor of NAYZILAM were observed on each of the components of the treatment success responder definition; termination of seizure(s) within 10 minutes after initial dose of study drug (80.6 versus 70.1%) and the absence of seizure recurrence between 10 minutes and 6 hours after the initial dose of study drug (58.2 versus 37.3%).Study 1 also evaluated the occurrence and time to next seizure after the initial blinded dose of study drug. A smaller proportion of NAYZILAM-treated patients experienced the next seizure within 24 hours after the initial blinded dose of study drug (37.3% versus 46.3%). NAYZILAM-treated patients experienced a statistically longer time-to-next-seizure than the placebo group (Figure 1).FIGURE 1: Kaplan-Meier Analysis of Time-to-Next-Seizure (Study 1)Analysis by gender revealed no substantial differences in treatment response. Informative subgroup analyses by age and race were not possible because of the small percentage of patients less than 18 years of age or 65 years of age or greater, and of non-White patients in the study.
