Description

Ampicillin and Sulbactam for Injection, USP is a sterile injectable antibacterial combination consisting of the semisynthetic antibacterial ampicillin sodium and the beta-lactamase inhibitor sulbactam sodium for intravenous and intramuscular administration.Ampicillin sodium is derived from the penicillin nucleus, 6-aminopenicillanic acid. Chemically, it is monosodium (2S, 5R, 6R)-6-[(R)-2-amino-2-phenylacetamido]-3,3-dimethyl-7-oxo-4-thia-1-azabicyclo[3.2.0] heptane-2-carboxylate and has a molecular weight of 371.39. Its chemical formula is C16H18N3NaO4S. The structural formula is:Sulbactam sodium is a derivative of the basic penicillin nucleus. Chemically, sulbactamsodium is sodium penicillinate sulfone; sodium (2S, 5R)-3,3-dimethyl-7-oxo-4-thia-1-azabicyclo [3.2.0]heptane-2-carboxylate 4,4-dioxide.Its chemical formula is C8H10NNaO5S with a molecular weight of 255.22. The structural formula is:Ampicillin and Sulbactam for Injection, USP parenteral combination is available as a white to off-white dry powder for reconstitution. Ampicillin and Sulbactam for Injection, USP dry powder is freely soluble in aqueous diluents to yield pale yellow to yellow solutions containing ampicillin sodium and sulbactam sodium equivalent to 250 mg ampicillin per mL and 125 mg sulbactam per mL. The pH of the solutions is between 8 and 10.Dilute solutions (up to 30 mg ampicillin and 15 mg sulbactam per mL) are essentially colorless to pale yellow. The pH of dilute solutions remains the same. 1.5 g of Ampicillin and Sulbactam for Injection, USP (1 g ampicillin as the sodium salt plus 0.5 g sulbactam as the sodium salt) parenteral contains approximately 115 mg (5 mEq) of sodium.3 g of Ampicillin and Sulbactam for Injection, USP (2 g ampicillin as the sodium salt plus 1 g sulbactam as the sodium salt) parenteral contains approximately 230 mg (10 mEq) of sodium.

General

Immediately after completion of a 15-minute intravenous infusion of Ampicillin and Sulbactam for Injection, USP, peak serum concentrations of ampicillin and sulbactam are attained. Ampicillin serum levels are similar to those produced by the administration of equivalent amounts of ampicillin alone. Peak ampicillin serum levels ranging from 109 to 150 mcg/mL are attained after administration of 2000 mg of ampicillin plus 1000 mg sulbactam and 40 to 71 mcg/mL after administration of 1000 mg ampicillin plus 500 mg sulbactam. The corresponding mean peak serum levels for sulbactam range from 48 to 88 mcg/mL and 21 to 40 mcg/mL, respectively. After an intramuscular injection of 1000 mg ampicillin plus 500 mg sulbactam, peak ampicillin serum levels ranging from 8 to 37 mcg/mL and peak sulbactam serum levels ranging from 6 to 24 mcg/mL are attained. The mean serum half-life of both drugs is approximately 1 hour in healthy volunteers.Approximately 75 to 85% of both ampicillin and sulbactam are excreted unchanged in the urine during the first 8 hours after administration of Ampicillin and Sulbactam for Injection, USP to individuals with normal renal function. Somewhat higher and more prolonged serum levels of ampicillin and sulbactam can be achieved with the concurrent administration of probenecid.In patients with impaired renal function the elimination kinetics of ampicillin and sulbactam are similarly affected, hence the ratio of one to the other will remain constant whatever the renal function. The dose of Ampicillin and Sulbactam for Injection, USP in such patients should be administered less frequently in accordance with the usual practice for ampicillin (see DOSAGE and ADMINISTRATION section).Ampicillin has been found to be approximately 28% reversibly bound to human serum protein and sulbactam approximately 38% reversibly bound.The following average levels of ampicillin and sulbactam were measured in the tissues and fluids listed:TABLE 1 Concentration of Ampicillin and Sulbactam for Injection, USP in Various Body Tissues and FluidsFluid or TissueDose (grams) Ampicillin/ SulbactamConcentration (mcg/mL or mcg/g) Ampicillin/ SulbactamPeritoneal Fluid 0.5/0.5 IV7/14Blister Fluid (Cantharides) 0.5/0.5 IV8/20Tissue Fluid 1/0.5 IV8/4Intestinal Mucosa 0.5/0.5 IV11/18Appendix 2/1 IV3/40Penetration of both ampicillin and sulbactam into cerebrospinal fluid in the presence of inflamed meninges has been demonstrated after IV administration of Ampicillin and Sulbactam for Injection, USP.The pharmacokinetics of ampicillin and sulbactam in pediatric patients receiving Ampicillin and Sulbactam for Injection, USP are similar to those observed in adults. Immediately after a 15-minute infusion of 50 to 75 mg Ampicillin and Sulbactam for Injection, USP /kg body weight, peak serum and plasma concentrations of 82 to 446 mcg ampicillin/mL and 44 to 203 mcg sulbactam/mL were obtained. Mean half-life values were approximately 1 hour.

Prescribing Ampicillin and Sulbactam for Injection, USP in the absence of a proven or strongly suspected bacterial infection or a prophylactic indication is unlikely to provide benefit to the patient and increases the risk of the development of drug-resistant bacteria.A high percentage of patients with mononucleosis who receive ampicillin develop a skin rash. Thus, ampicillin class antibacterials should not be administered to patients with mononucleosis. In patients treated with Ampicillin and Sulbactam for Injection, USP the possibility of superinfections with mycotic or bacterial pathogens should be kept in mind during therapy. If superinfections occur (usually involving Pseudomonas or Candida), the drug should be discontinued and/or appropriate therapy instituted.

Microbiology

Ampicillin is similar to benzyl penicillin in its bactericidal action against susceptible organisms during the stage of active multiplication. It acts through the inhibition of cell wall mucopeptide biosynthesis. Ampicillin has a broad spectrum of bactericidal activity against many gram-positive and gram-negative aerobic and anaerobic bacteria. (Ampicillin is, however, degraded by beta-lactamases, and therefore the spectrum of activity does not normally include organisms which produce these enzymes.)A wide range of beta-lactamases found in microorganisms resistant to penicillins and cephalosporins have been shown in biochemical studies with cell-free bacterial systems to be irreversibly inhibited by sulbactam. Although sulbactam alone possesses little useful antibacterial activity except against the Neisseriaceae, whole organism studies have shown that sulbactam restores ampicillin activity against beta-lactamase producing strains. In particular, sulbactam has good inhibitory activity against the clinically important plasmid mediated beta-lactamases most frequently responsible for transferred drug resistance. Sulbactam has no effect on the activity of ampicillin against ampicillin susceptible strains.The presence of sulbactam in the Ampicillin and Sulbactam for Injection, USP formulation effectively extends the antibacterial spectrum of ampicillin to include many bacteria normally resistant to it and to other beta-lactam antibacterials. Thus, Ampicillin and Sulbactam for Injection, USP possesses the properties of a broad-spectrum antibacterial and a beta-lactamase inhibitor. While in vitro studies have demonstrated the susceptibility of most strains of the following organisms, clinical efficacy for infections other than those included in the INDICATIONSAND USAGE section has not been documented.Gram-Positive Bacteria: Staphylococcus aureus (beta-lactamase and non-beta-lactamase producing), Staphylococcus epidermidis (beta-lactamase and non-beta-lactamase producing), Staphylococcus saprophyticus (beta-lactamase and non-beta-lactamase producing), Streptococcus faecalis† (Enterococcus), Streptococcus pneumoniae† (formerly D. pneumoniae), Streptococcus pyogenes†, Streptococcus viridans†. Gram-Negative Bacteria: Hemophilus influenzae (beta-lactamase and non-beta-lactamase producing), Moraxella (Branhamella) catarrhalis (beta-lactamase and non-beta-lactamase producing), Escherichia coli (beta-lactamase and non-beta-lactamase producing), Klebsiella species (all known strains are beta-lactamase producing), Proteus mirabilis (beta-lactamase and non-beta-lactamase producing), Proteus vulgaris, Providencia rettgeri, Providencia stuartii, Morganella morganii, and Neisseria gonorrhoeae (beta-lactamase and non-beta-lactamase producing). Anaerobes: Clostridium species†, Peptococcus species†, Peptostreptococcus species, Bacteroides species, including B. fragilis. † These are not beta-lactamase producing strains and, therefore, are susceptible to ampicillin alone. Susceptibility Testing Diffusion TechniqueFor the disk diffusion method of susceptibility testing, a 20 mcg (10 mcg ampicillin + 10 mcg sulbactam) disk should be used. The standardized procedure1,2 requires the use of a standardized inoculum concentration. With this procedure, a report from the laboratory of "Susceptible" indicates that the infecting organism is likely to respond to Ampicillin and Sulbactam for Injection, USP therapy and a report of "Resistant" indicates that the infecting organism is not likely to respond to therapy. An "Intermediate" susceptibility report suggests that the infecting organism would be susceptible to Ampicillin and Sulbactam for Injection, USP if a higher dosage is used or if the infection is confined to tissues or fluids (e.g., urine) in which high antibacterial levels are attained.Dilution TechniquesBroth, agar, microdilution or equivalent methods may be used to determine the minimal inhibitory concentration (MIC) value for susceptibility of bacterial isolates using standardized methods, inoculums and concentrations of ampicillin/sulbactam1,3,4 The recommended dilution method employs a constant ampicillin/sulbactam ratio of 2:1 in all tubes with increasing concentrations of ampicillin. MIC's are reported in terms of ampicillin concentration in the presence of sulbactam at a constant 2 parts ampicillin to 1 part sulbactam.TABLE 2Recommended Ampicillin/Sulbactam, Disk Diffusion and MIC Susceptibility Rangesa,b,c(Zone diameter in mm)OrganismsInhibition zone diameter (mm)ResistantIntermediateSusceptibleEnterobacteriaceae, Acinetobacter calcoaceticus, Staphylococcus spp.≤1112-14≥15Hemophilus influenzae≤19--≥20OrganismsMIC (mcg/mL of ampicillin)ResistantIntermediateSusceptibleEnterobacteriaceae, Acinetobacter calcoaceticus, Staphylococcus spp.≥3216≤8Hemophilus influenzae≥4--≤2a The non-beta-lactamase producing organisms which are normally susceptible to ampicillin, such as Streptococci, will have similar zone sizes as for ampicillin disks. b Staphylococci resistant to methicillin, oxacillin, or nafcillin must be considered resistant to Ampicillin and Sulbactam for Injection, USP.c The quality control cultures should have the following assigned daily ranges for ampicillin/sulbactam (see Table 3):TABLE 3 Quality control ranges for ampicillin/sulbactam disk diffusion and MIC determinationsDisk Diffusion(Zone diameter in mm)MIC(mcg/mL ampicillin/mcg/mL sulbactam)E. coli (ATCC 25922)19-242/1–8/4S. aureus (ATCC 25923)29–37N/AE. coli (ATCC 35218)13–198/4–32/16H. influenza (ATCC 49247)14–222/1-8/4

Indications And Usage

Ampicillin and Sulbactam for Injection, USP is indicated for the treatment of infections due to susceptible strains of the designated microorganisms in the conditions listed below. Skin and Skin Structure Infections caused by beta-lactamase producing strains of Staphylococcus aureus, Escherichia coli*, Klebsiella spp.* (including K. pneumoniae*), Proteus mirabilis*, Bacteroides fragilis*, Enterobacter spp.*, and Acinetobacter calcoaceticus*. NOTE: For information on use in pediatric patients see PRECAUTIONS, Pediatric Use and CLINICAL STUDIES sections.Intra-Abdominal Infections caused by beta-lactamase producing strains of Escherichia coli, Klebsiella spp. (including K. pneumoniae*), Bacteroides spp. (including B. fragilis), and Enterobacter spp.*. Gynecological Infections caused by beta-lactamase producing strains of Escherichia coli*, and Bacteroides spp.* (including B. fragilis*).*Efficacy for this organism in this organ system was studied in fewer than 10 infections. While Ampicillin and Sulbactam for Injection, USP is indicated only for the conditions listed above, infections caused by ampicillin-susceptible organisms are also amenable to treatment with Ampicillin and Sulbactam for Injection, USP due to its ampicillin content. Therefore, mixed infections caused by ampicillin-susceptible organisms and beta-lactamase producing organisms susceptible to Ampicillin and Sulbactam for Injection, USP should not require the addition of another antibacterial.Appropriate culture and susceptibility tests should be performed before treatment in order to isolate and identify the organisms causing infection and to determine their susceptibility to Ampicillin and Sulbactam for Injection, USP.Therapy may be instituted prior to obtaining the results from bacteriological and susceptibility studies, when there is reason to believe the infection may involve any of the beta-lactamase producing organisms listed above in the indicated organ systems.Once the results are known, therapy should be adjusted if appropriate.To reduce the development of drug-resistant bacteria and maintain the effectiveness of Ampicillin and Sulbactam for Injection, USP and other antibacterial drugs, Ampicillin and Sulbactam for Injection, USP should be used only to treat or prevent infections that are proven or strongly suspected to be caused by susceptible bacteria. When culture and susceptibility information are available, they should be considered in selecting or modifying antibacterial therapy. In the absence of such data, local epidemiology an susceptibility patterns may contribute to the empiric selection of therapy.

Contraindications

The use of Ampicillin and Sulbactam for Injection, USP is contraindicated in individuals with a history of serious hypersensitivity reactions (e.g., anaphylaxis or Stevens-Johnson syndrome) to ampicillin, sulbactam or to other beta-lactam antibacterial drugs (e.g., penicillins and cephalosporins).Ampicillin and Sulbactam for Injection, USP is contraindicated in patients with a previous history of cholestatic jaundice/hepatic dysfunction associated with Ampicillin and Sulbactam for Injection, USP.

Warnings

HypersensitivitySerious and occasionally fatal hypersensitivity (anaphylactic) reactions have been reported in patients on penicillin therapy. These reactions are more apt to occur in individuals with a history of penicillin hypersensitivity and/or hypersensitivity reactions to multiple allergens. There have been reports of individuals with a history of penicillin hypersensitivity who have experienced severe reactions when treated with cephalosporins. Before therapy with a penicillin, careful inquiry should be made concerning previous hypersensitivity reactions to penicillins, cephalosporins, and other allergens. If an allergic reaction occurs, Ampicillin and Sulbactam for Injection, USP should be discontinued and the appropriate therapy instituted.HepatotoxicityHepatic dysfunction, including hepatitis and cholestatic jaundice has been associated with the use of Ampicillin and Sulbactam for Injection, USP. Hepatic toxicity is usually reversible; however, deaths have been reported. Hepatic function should be monitored at regular intervals in patients with hepatic impairment.Clostridium difficile-Associated DiarrheaClostridium difficile associated diarrhea (CDAD) has been reported with use of nearly all antibacterial agents, including Ampicillin and Sulbactam for Injection, USP, and may range in severity from mild diarrhea to fatal colitis. Treatment with antibacterial agents alters the normal flora of the colon leading to overgrowth of C. difficile.C. difficile produces toxins A and B which contribute to the development of CDAD. Hypertoxin producing strains of C. difficile cause increased morbidity and mortality, as these infections can be refractory to antimicrobial therapy and may require colectomy. CDAD must be considered in all patients who present with diarrhea following antibacterial drug use. Careful medical history is necessary since CDAD has been reported to occur over two months after the administration of antibacterial agents.If CDAD is suspected or confirmed, ongoing antibacterial drug use not directed against C. difficile may need to be discontinued. Appropriate fluid and electrolyte management, protein supplementation, antibacterial treatment of C. difficile, and surgical evaluation should be instituted as clinically indicated.

Information For Patients

Patients should be counseled that antibacterial drugs including Ampicillin and Sulbactam for Injection, USP should only be used to treat bacterial infections. They do not treat viral infections (e.g., the common cold). When Ampicillin and Sulbactam for Injection, USP is prescribed to treat a bacterial infection, patients should be told that although it is common to feel better early in the course of therapy, the medication should be taken exactly as directed. Skipping doses or not completing the full course of therapy may (1) decrease the effectiveness of the immediate treatment and (2) increase the likelihood that bacteria will develop resistance and will not be treatable by Ampicillin and Sulbactam for Injection, USP or other antibacterial drugs in the future. Diarrhea is a common problem caused by antibacterials which usually ends when the antibacterial is discontinued. Sometimes after starting treatment with antibacterials, patients can develop watery and bloody stools (with or without stomach cramps and fever) even as late as two or more months after having taken the last dose of the antibacterial. If this occurs, patients should contact their physician as soon as possible.

Drug Interactions

Probenecid decreases the renal tubular secretion of ampicillin and sulbactam. Concurrent use of probenecid with Ampicillin and Sulbactam for Injection, USP may result in increased and prolonged blood levels of ampicillin and sulbactam. The concurrent administration of allopurinol and ampicillin increases substantially the incidence of rashes in patients receiving both drugs as compared to patients receiving ampicillin alone. It is not known whether this potentiation of ampicillin rashes is due to allopurinol or the hyperuricemia present in these patients. There are no data with Ampicillin and Sulbactam for Injection, USP and allopurinol administered concurrently. Ampicillin and Sulbactam for Injection, USP and aminoglycosides should not be reconstituted together due to the in vitro inactivation of aminoglycosides by the ampicillin component of Ampicillin and Sulbactam for Injection, USP.

Drug/Laboratory Test Interactions

Administration of Ampicillin and Sulbactam for Injection, USP will result in high urine concentration of ampicillin. High urine concentrations of ampicillin may result in false positive reactions when testing for the presence of glucose in urine using Clinitest®, Benedict's Solution or Fehling's Solution. It is recommended that glucose tests based on enzymatic glucose oxidase reactions (such as Clinistix® or Testape) be used. Following administration of ampicillin to pregnant women, a transient decrease in plasma concentration of total conjugated estriol, estriol-glucuronide, conjugated estrone and estradiol has been noted. This effect may also occur with Ampicillin and Sulbactam for Injection, USP.

Carcinogenesis, Mutagenesis, Impairment Of Fertility

Long-term studies in animals have not been performed to evaluate carcinogenic or mutagenic potential.

Pregnancy

Pregnancy Category BReproduction studies have been performed in mice, rats, and rabbits at doses up to ten (10) times the human dose and have revealed no evidence of impaired fertility or harm to the fetus due to Ampicillin and Sulbactam for Injection, USP. There are, however, no adequate and well-controlled studies in pregnant women. Because animal reproduction studies are not always predictive of human response, this drug should be used during pregnancy only if clearly needed. (See PRECAUTIONS, Drug/Laboratory Test Interactions section).

Labor And Delivery

Studies in guinea pigs have shown that intravenous administration of ampicillin decreased the uterine tone, frequency of contractions, height of contractions, and duration of contractions. However, it is not known whether the use of Ampicillin and Sulbactam for Injection, USP in humans during labor or delivery has immediate or delayed adverse effects on the fetus, prolongs the duration of labor, or increases the likelihood that forceps delivery or other obstetrical intervention or resuscitation of the newborn will be necessary.

Nursing Mothers

Low concentrations of ampicillin and sulbactam are excreted in the milk; therefore, caution should be exercised when Ampicillin and Sulbactam for Injection, USP is administered to a nursing woman.

Pediatric Use:

The safety and effectiveness of Ampicillin and Sulbactam for Injection, USP have been established for pediatric patients one year of age and older for skin and skin structure infections as approved in adults. Use of Ampicillin and Sulbactam for Injection, USP in pediatric patients is supported by evidence from adequate and well-controlled studies in adults with additional data from pediatric pharmacokinetic studies, a controlled clinical trial conducted in pediatric patients and post-marketing adverse events surveillance (see CLINICAL PHARMACOLOGY, INDICATIONS AND USAGE, ADVERSE REACTIONS,DOSAGE AND ADMINISTRATION, and CLINICAL STUDIES sections). The safety and effectiveness of Ampicillin and Sulbactam for Injection, USP have not been established for pediatric patients for intra-abdominal infections.

Adult Patients

Ampicillin and Sulbactam for Injection, USP is generally well tolerated. The following adverse reactions have been reported in clinical trials.

Local Adverse Reactions

Pain at IM injection site - 16% Pain at IV injection site - 3% Thrombophlebitis - 3% Phlebitis – 1.2%

Systemic Adverse Reactions

The most frequently reported adverse reactions were diarrhea in 3% of the patients and rash in less than 2% of the patients. Additional systemic reactions reported in less than 1% of the patients were: itching, nausea, vomiting, candidiasis, fatigue, malaise, headache, chest pain, flatulence, abdominal distension, glossitis, urine retention, dysuria, edema, facial swelling, erythema, chills, tightness in throat, substernal pain, epistaxis and mucosal bleeding.

Pediatric Patients

Available safety data for pediatric patients treated with Ampicillin and Sulbactam for Injection, USP demonstrate a similar adverse events profile to those observed in adult patients. Additionally, atypical lymphocytosis has been observed in one pediatric patient receiving Ampicillin and Sulbactam for Injection, USP.

Adverse Laboratory Changes

Adverse laboratory changes without regard to drug relationship that were reported during clinical trials were: Hepatic: Increased AST (SGOT), ALT (SGPT), alkaline phosphatase, and LDH. Hematologic: Decreased hemoglobin, hematocrit, RBC, WBC, neutrophils, lymphocytes, platelets and increased lymphocytes, monocytes, basophils, eosinophils, and platelets. Blood Chemistry: Decreased serum albumin and total proteins. Renal: Increased BUN and creatinine. Urinalysis: Presence of RBCs and hyaline casts in urine. Postmarketing ExperienceIn addition to adverse reactions reported from clinical trials, the following have been identified during post-marketing use of Ampicillin and Sulbactam for Injection, USP or other products containing ampicillin. Because they are reported voluntarily from a population of unknown size, estimates of frequency cannot be made. These events have been chosen for inclusion due to a combination of their seriousness, frequency, or potential causal connection to Ampicillin and Sulbactam for Injection, USP.Blood and Lymphatic System Disorders: Hemolytic anemia, thrombocytopenic purpura, and agranulocytosis have been reported. These reactions are usually reversible on discontinuation of therapy and are believed to be hypersensitivity phenomena. Some individuals have developed positive direct Coombs Tests during treatment with Ampicillin and Sulbactam for Injection, USP, as with other beta-lactam antibacterials.Gastrointestinal Disorders: Cholestatic hepatitis, cholestasis, hyperbilirubinemia, jaundice, abnormal hepatic function, gastritis, stomatitis, black “hairy” tongue and Clostridium difficile associated diarrhea (see CONTRAINDICATIONS and WARNINGS sections).General Disorders and Administration Site Conditions: Injection site reaction.Immune System Disorders: Serious and fatal hypersensitivity (anaphylactic) reactions (See WARNINGS section).Nervous System Disorders: Convulsion.Renal and Urinary Disorders: Tubulointerstitial nephritis.Skin and Subcutaneous Tissue Disorders: Toxic epidermal necrolysis, Stevens-Johnson syndrome, and acute generalized exanthematous pustulosis (AGEP), urticaria, erythema multiforme, and exfoliative dermatitis (see CONTRAINDICATIONS section).To report SUSPECTED ADVERSE REACTIONS, contact WG Critical Care, LLC at1-866-562-4708 or the FDA at 1-800-FDA-1088 or www.fda.gov/medwatch.

Overdosage

Neurological adverse reactions, including convulsions, may occur with the attainment of high CSF levels of beta-lactams. Ampicillin may be removed from circulation by hemodialysis. The molecular weight, degree of protein binding and pharmacokinetics profile of sulbactam suggest that this compound may also be removed by hemodialysis.

Clinical Studies

Skin and Skin Structure Infections in Pediatric Patients: Data from a controlled clinical trial conducted in pediatric patients provided evidence supporting the safety and efficacy of Ampicillin and Sulbactam for Injection, USP for the treatment of skin and skin structure infections. Of 99 pediatric patients evaluable for clinical efficacy, 60 patients received a regimen containing intravenous Ampicillin and Sulbactam for Injection, USP, and 39 patients received a regimen containing intravenous cefuroxime. This trial demonstrated similar outcomes (assessed at an appropriate interval after discontinuation of all antimicrobial therapy) for Ampicillin and Sulbactam for Injection, USP - and cefuroxime - treated patients: TABLE 4 Therapeutic Regimen Clinical SuccessClinical FailureAmpicillin and Sulbactam for Injection, USP51/60 (85%) 9/60 (15%) Cefuroxime 34/39 (87%) 5/39 (13%) Most patients received a course of oral antimicrobials following initial treatment with intravenous administration of parenteral antimicrobials. The study protocol required that the following three criteria be met prior to transition from intravenous to oral antimicrobial therapy: (1) receipt of a minimum of 72 hours of intravenous therapy; (2) no documented fever for prior 24 hours; and (3) improvement or resolution of the signs and symptoms of infection. The choice of oral antimicrobial agent used in this trial was determined by susceptibility testing of the original pathogen, if isolated, to oral agents available. The course of oral antimicrobial therapy should not routinely exceed 14 days.

Dosage And Administration

Ampicillin and Sulbactam for Injection, USP may be administered by either the IV or the IM routes.For IV administration, the dose can be given by slow intravenous injection over at least 10-15 minutes or can also be delivered in greater dilutions with 50-100 mL of a compatible diluent as an intravenous infusion over 15-30 minutes.Ampicillin and Sulbactam for Injection, USP may be administered by deep intramuscular injection (see DIRECTIONS FOR USE - Preparation for Intramuscular Injection section). The recommended adult dosage of Ampicillin and Sulbactam for Injection, USP is 1.5 g (1 g ampicillin as the sodium salt plus 0.5 g sulbactam as the sodium salt) to 3 g (2 g ampicillin as the sodium salt plus 1 g sulbactam as the sodium salt) every six hours. This 1.5 to 3 g range represents the total of ampicillin content plus the sulbactam content of Ampicillin and Sulbactam for Injection, USP and corresponds to a range of 1 g ampicillin/0.5 g sulbactam to 2 g ampicillin/1 g sulbactam. The total dose of sulbactam should not exceed 4 grams per day.Pediatric Patients 1 Year of Age or OlderThe recommended daily dose of Ampicillin and Sulbactam for Injection, USP in pediatric patients is 300 mg per kg of body weight administered via intravenous infusion in equally divided doses every 6 hours. This 300 mg/kg/day dosage represents the total ampicillin content plus the sulbactam content of Ampicillin and Sulbactam for Injection, USP and corresponds to 200 mg ampicillin/100 mg sulbactam per kg per day. The safety and efficacy of Ampicillin and Sulbactam for Injection, USP administered via intramuscular injection in pediatric patients have not been established. Pediatric patients weighing 40 kg or more should be dosed according to adult recommendations, and the total dose of sulbactam should not exceed 4 grams per day. The course of intravenous therapy should not routinely exceed 14 days. In clinical trials, most children received a course of oral antimicrobials following initial treatment with intravenous Ampicillin and Sulbactam for Injection, USP (see CLINICAL STUDIES section).

Impaired Renal Function

In patients with impairment of renal function the elimination kinetics of ampicillin and sulbactam are similarly affected, hence the ratio of one to the other will remain constant whatever the renal function. The dose of Ampicillin and Sulbactam for Injection, USP in such patients should be administered less frequently in accordance with the usual practice for ampicillin and according to the following recommendations: TABLE 5 Ampicillin And Sulbactam for Injection, USP Dosage Guide for Patients with Renal Impairment Creatinine Clearance (mL/min/1.73m2)Ampicillin/ Sulbactam Half-Life (Hours)RecommendedAmpicillin and Sulbactam for Injection, USP Dosage≥ 30 1 1.5-3 g q 6 h-q 8h 15-29 5 1.5-3 g q 12h 5-14 9 1.5-3 g q 24h When only serum creatinine is available, the following formula (based on sex, weight, and age of the patient) may be used to convert this value into creatinine clearance. The serum creatinine should represent a steady state of renal function. Males weight (kg) × (140 - age)72 × serum creatinine Females 0.85 × above value Parenteral drug products should be inspected visually for particulate matter and discoloration prior to administration, whenever solution and container permit.

Compatibility, Reconstitution And Stability

Ampicillin and Sulbactam for Injection, USP sterile powder is to be stored at 20 to 25°C (68 to 77°F) [See USP Controlled Room Temperature] prior to reconstitution.When concomitant therapy with aminoglycosides is indicated, Ampicillin and Sulbactam for Injection, USP and aminoglycosides should be reconstituted and administered separately, due to the in vitro inactivation of aminoglycosides by any of the aminopenicillins.

Directions For Use

General Dissolution ProceduresAmpicillin and Sulbactam for Injection, USP sterile powder for intravenous and intramuscular use may be reconstituted with any of the compatible diluents described in this insert. Solutions should be allowed to stand after dissolution to allow any foaming to dissipate in order to permit visual inspection for complete solubilization.

Preparation For Intravenous Use

1.5 g and 3 g Bottles: Ampicillin and Sulbactam for Injection, USP sterile powder in piggyback units may be reconstituted directly to the desired concentrations using any of the following parenteral diluents. Reconstitution of Ampicillin and Sulbactam for Injection, USP at the specified concentrations, with these diluents provide stable solutions for the time periods indicated in the following table: (After the indicated time periods, any unused portions of solutions should be discarded.)TABLE 6 DiluentMaximum Concentration (mg/mL) Ampicillin and Sulbactam for Injection, USP Use PeriodsSterile Water for Injection 45 (30/15) 45 (30/15) 30 (20/10) 8 hrs at 25°C 48 hrs at 4°C 72 hrs at 4°C 0.9% Sodium Chloride Injection 45 (30/15) 45 (30/15) 30 (20/10) 8 hrs at 25°C 48 hrs at 4°C 72 hrs at 4°C 5% Dextrose Injection 30 (20/10) 30 (20/10) 3 (2/1) 2 hrs at 25°C 4 hrs at 4°C 2 hrs at 25°C Lactated Ringer's Injection 45 (30/15) 45 (30/15) 8 hrs at 25°C 24 hrs at 4°C M/6 Sodium Lactate Injection 45 (30/15) 45 (30/15) 8 hrs at 25°C 8 hrs at 4°C 5% Dextrose in 0.45% Saline 3 (2/1) 15 (10/5) 4 hrs at 25°C 4 hrs at 4°C 10% Invert Sugar 3 (2/1) 30 (20/10) 4 hrs at 25°C 3 hrs at 4°C If piggyback bottles are unavailable, standard vials of Ampicillin and Sulbactam for Injection, USP sterile powder may be used. Initially, the vials may be reconstituted with Sterile Water for Injection to yield solutions containing 375 mg Ampicillin and Sulbactam for Injection, USP per mL (250 mg ampicillin/125 mg sulbactam per mL). An appropriate volume should then be immediately diluted with a suitable parenteral diluent to yield solutions containing 3 to 45 mg Ampicillin and Sulbactam for Injection, USP per mL (2 to 30 mg ampicillin/1 to 15 mg sulbactam per mL).

Preparation For Intramuscular Injection

1.5 g and 3 g Standard Vials: Vials for intramuscular use may be reconstituted with Sterile Water for Injection USP, 0.5% Lidocaine Hydrochloride Injection, USP or 2% Lidocaine Hydrochloride Injection, USP. Consult the following table for recommended volumes to be added to obtain solutions containing 375 mg Ampicillin and Sulbactam for Injection, USP per mL (250 mg ampicillin/125 mg sulbactam per mL). Note: Use only freshly prepared solutions and administer within one hour after preparation.TABLE 7 Ampicillin and Sulbactam forInjection, USP Vial SizeVolume of Diluent to be AddedWithdrawal Volume*1.5 g 3.2 mL 4 mL 3 g 6.4 mL 8 mL *There is sufficient excess present to allow withdrawal and administration of the stated volumes. Animal Pharmacology: While reversible glycogenosis was observed in laboratory animals, this phenomenon was dose- and time-dependent and is not expected to develop at the therapeutic doses and corresponding plasma levels attained during the relatively short periods of combined ampicillin/sulbactam therapy in man.
