Pediatric use information is approved for Braintree Laboratories, Inc.’s SUPREP BOWEL PREP KIT (sodium sulfate, potassium sulfate, and magnesium sulfate) oral solution. However, due to Braintree Laboratories, Inc.’s marketing exclusivity rights, this drug product is not labeled with that pediatric information. 

Sodium sulfate, potassium sulfate and magnesium sulfate oral solution is contraindicated in the following conditions:

• Gastrointestinal obstruction or ileus [see Warnings and Precautions (5.6)]
• Bowel perforation [see Warnings and Precaution (5.6)]
• Toxic colitis or toxic megacolon
• Gastric retention
• Hypersensitivity to any of the ingredients in sodium sulfate, potassium sulfate and magnesium sulfate oral solution

Advise all patients to hydrate adequately before, during, and after the use of sodium sulfate, potassium sulfate and magnesium sulfate oral solution. If a patient develops significant vomiting or signs of dehydration after taking sodium sulfate, potassium sulfate and magnesium sulfate oral solution, consider performing post-colonoscopy lab tests (electrolytes, creatinine, and BUN).

Fluid and electrolyte disturbances can lead to serious adverse events including cardiac arrhythmias, seizures and renal impairment. Correct fluid and electrolyte abnormalities before treatment with sodium sulfate, potassium sulfate and magnesium sulfate oral solution. Use sodium sulfate, potassium sulfate and magnesium sulfate oral solution with caution in patients with conditions, or who are using medications, that increase the risk for fluid and electrolyte disturbances or may increase the risk of adverse events of seizure, arrhythmias, and renal impairment [see Drug Interactions (7.1)].

Sodium sulfate, potassium sulfate and magnesium sulfate oral solution can cause temporary elevations in uric acid [see Adverse Reactions (6.1)]. Uric acid fluctuations in patients with gout may precipitate an acute flare. The potential for uric acid elevation should be considered before administering sodium sulfate, potassium sulfate and magnesium sulfate oral solution to patients with gout or other disorders of uric acid metabolism. 

There have been rare reports of serious arrhythmias associated with the use of ionic osmotic laxative products for bowel preparation. Use caution when prescribing sodium sulfate, potassium sulfate and magnesium sulfate oral solution for patients at increased risk of arrhythmias (e.g., patients with a history of prolonged QT, uncontrolled arrhythmias, recent myocardial infarction, unstable angina, congestive heart failure, or cardiomyopathy). Consider pre-dose and post-colonoscopy ECGs in patients at increased risk of serious cardiac arrhythmias. 

There have been reports of generalized tonic-clonic seizures and/or loss of consciousness associated with use of bowel preparation products in patients with no prior history of seizures. The seizure cases were associated with electrolyte abnormalities (e.g., hyponatremia, hypokalemia, hypocalcemia, and hypomagnesemia) and low serum osmolality. The neurologic abnormalities resolved with correction of fluid and electrolyte abnormalities.

Use caution when prescribing sodium sulfate, potassium sulfate and magnesium sulfate oral solution for patients with a history of seizures and in patients at increased risk of seizure, such as patients taking medications that lower the seizure threshold (e.g., tricyclic antidepressants), patients withdrawing from alcohol or benzodiazepines, or patients with known or suspected hyponatremia [see Drug Interactions (7.1)]. 

Use sodium sulfate, potassium sulfate and magnesium sulfate oral solution with caution in patients with impaired renal function or patients taking concomitant medications that may affect renal function (such as diuretics, angiotensin converting enzyme inhibitors, angiotensin receptor blockers, or non-steroidal anti-inflammatory drugs) [see Drug Interactions (7.1)]. These patients may be at risk for renal injury. Advise these patients of the importance of adequate hydration with sodium sulfate, potassium sulfate and magnesium sulfate oral solution and consider performing baseline and post-colonoscopy laboratory tests (electrolytes, creatinine, and BUN) in these patients [see Use in Specific Populations (8.6)]. 

Osmotic laxative products may produce colonic mucosal aphthous ulcerations, and there have been reports of more serious cases of ischemic colitis requiring hospitalization. Concurrent use of stimulant laxatives and sodium sulfate, potassium sulfate and magnesium sulfate oral solution may increase these risks [see Drug Interactions (7.3)]. Consider the potential for mucosal ulcerations resulting from the bowel preparation when interpreting colonoscopy findings in patients with known or suspect inflammatory bowel disease (IBD).

If gastrointestinal obstruction or perforation is suspected, perform appropriate diagnostic studies to rule out these conditions before administering sodium sulfate, potassium sulfate and magnesium sulfate oral solution [see Contraindications (4)].

Use with caution in patients with severe active ulcerative colitis. 

Patients with impaired gag reflex or other swallowing abnormalities are at risk for regurgitation or aspiration of sodium sulfate, potassium sulfate and magnesium sulfate oral solution. Observe these patients during administration of sodium sulfate, potassium sulfate and magnesium sulfate oral solution. Use with caution in these patients. 

The following important adverse reactions for bowel preparations are described elsewhere in the labeling:

• Serious Fluid and Serum Chemistry Abnormalities [see Warnings and Precautions (5.1)]
• Cardiac Arrhythmias [see Warnings and Precautions (5.2)]
• Seizures [see Warnings and Precautions (5.3)]
• Use in Patients with Risk of Renal Injury [see Warnings and Precautions (5.4)]
• Colonic Mucosal Ulceration and Ischemic Colitis [see Warnings and Precautions (5.5)]
• Patients with Significant Gastrointestinal Disease [see Warnings and Precautions (5.6)]
• Aspiration [see Warnings and Precautions (5.7)] 

Because clinical studies are conducted under widely varying conditions, adverse reaction rates observed in the clinical studies of a drug cannot be directly compared to rates in clinical studies of another drug and may not reflect the rates observed in practice.

• Administer oral medications at least one hour before starting each dose of sodium sulfate, potassium sulfate and magnesium sulfate oral solution.
• Administer tetracycline and fluoroquinolone antibiotics, iron, digoxin, chlorpromazine, and penicillamine at least 2 hours before and not less than 6 hours after administration of sodium sulfate, potassium sulfate and magnesium sulfate oral solution to avoid chelation with magnesium. 

Concurrent use of stimulant laxatives and sodium sulfate, potassium sulfate and magnesium sulfate oral solution may increase the risk of mucosal ulceration or ischemic colitis. Avoid use of stimulant laxatives (e.g., bisacodyl, sodium picosulfate) while taking sodium sulfate, potassium sulfate and magnesium sulfate oral solution [see Warnings and Precautions (5.5)]. 

Risk Summary

There are no available data on sodium sulfate, potassium sulfate and magnesium sulfate oral solution use in pregnant women to evaluate for a drug- associated risk of major birth defects, miscarriage, or adverse maternal or fetal outcomes. Animal reproductive studies have not been conducted with sodium sulfate, potassium sulfate, and magnesium sulfate (sodium sulfate, potassium sulfate and magnesium sulfate oral solution).

The estimated background risk of major birth defects and miscarriage for the indicated population is unknown. All pregnancies have a background risk of birth defect, loss, or other adverse outcomes. 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. 

Risk Summary

There are no data available data on the presence of sodium sulfate, potassium sulfate and magnesium sulfate oral solution in human or animal milk, the effects on the breastfed child, or the effects on milk production. The developmental and health benefits of breastfeeding should be considered along with the mother’s clinical need for sodium sulfate, potassium sulfate and magnesium sulfate oral solution and any potential adverse effects on the breastfed child from sodium sulfate, potassium sulfate and magnesium sulfate oral solution or from the underlying maternal condition. 

The safety and effectiveness of sodium sulfate, potassium sulfate and magnesium sulfate oral solution in pediatric patients less than 12 years of age have not been established.

 Pediatric use information is approved for Braintree Laboratories, Inc.’s SUPREP BOWEL PREP KIT (sodium sulfate, potassium sulfate, and magnesium sulfate) oral solution. However, due to Braintree Laboratories, Inc.’s marketing exclusivity rights, this drug product is not labeled with that pediatric information.

Of the 375 patients who received sodium sulfate, potassium sulfate and magnesium sulfate oral solution in clinical trials, 94 (25%) were 65 years of age or older, and 25 (7%) were 75 years of age or older. No overall differences in safety or effectiveness of sodium sulfate, potassium sulfate and magnesium sulfate oral solution, administered as the recommended split-dose (2-day) regimen, were observed between geriatric patients and younger patients. Geriatric patients reported more vomiting when sodium sulfate, potassium sulfate and magnesium sulfate oral solution was given as a one-day preparation (not a recommended regimen).

Elderly patients are more likely to have decreased hepatic, renal or cardiac function and may be more susceptible to adverse reactions resulting from fluid and electrolyte abnormalities [see Warnings and Precautions (5.1)]. 

Use sodium sulfate, potassium sulfate and magnesium sulfate oral solution with caution in patients with renal impairment or patients taking concomitant medications that may affect renal function. These patients may be at risk for renal injury. Advise these patients of the importance of adequate hydration before, during and after use of sodium sulfate, potassium sulfate and magnesium sulfate oral solution and consider performing baseline and post-colonoscopy laboratory tests (electrolytes, creatinine, and BUN) in these patients [see Warnings and Precautions (5.4)]. 

Overdosage of more than the recommended dose of sodium sulfate, potassium sulfate and magnesium sulfate oral solution may lead to severe electrolyte disturbances, as well as dehydration and hypovolemia, with signs and symptoms of these disturbances. [see Warnings and Precautions (5.1, 5.2, 5.3)]. Monitor for fluid and electrolyte disturbances and treat symptomatically.

Sulfate salts provide sulfate anions, which are poorly absorbed. The osmotic effect of unabsorbed sulfate anions and the associated cations causes water to be retained within the gastrointestinal tract. 

No formal pharmacodynamic studies have been conducted with sodium sulfate, potassium sulfate and magnesium sulfate oral solution. 

Absorption and Elimination

After administration of sodium sulfate, potassium sulfate and magnesium sulfate oral solution in six healthy subjects, the time at which serum sulfate reached its highest point (T_max) was approximately 17 hours after the first dose or approximately 5 hours after the second dose, and then declined with a half-life of 8.5 hours.

Excretion

Fecal excretion was the primary route of sulfate elimination.

Specific Populations

Patients with Renal Impairment

The disposition of sulfate after ingestion of sodium sulfate, potassium sulfate and magnesium sulfate oral solution was studied in patients (N=6) with moderate renal impairment (creatinine clearance of 30 to 49 mL/min). In patients with moderate renal impairment, mean AUC was 54% higher and mean C_max was 44% higher, than healthy subjects.

The mean sulfate concentrations in healthy subjects and in patients with moderate renal impairment returned to their respective baselines by Day 6 after dose initiation. Urinary excretion of sulfate over 30 hours after the first dose was approximately 16% lower in patients with moderate renal impairment than in healthy subjects. These differences are not considered clinically meaningful.

Patients with Hepatic Impairment

The disposition of sulfate after ingestion of sodium sulfate, potassium sulfate and magnesium sulfate oral solution was studied in patients (N=6) with mild to moderate hepatic impairment (Child-Pugh grades A and B). Systemic exposure of serum sulfate (AUC and C_max) was similar between healthy subjects and patients with hepatic impairment. The mean sulfate concentrations in healthy subjects and in patients with mild to moderate hepatic impairment returned to their respective baselines by Day 6 after dose initiation. Urinary excretion of sulfate over 30 hours after the first dose was similar between patients with hepatic impairment and healthy subjects. 

The sulfate salts of sodium, potassium, and magnesium contained in sodium sulfate, potassium sulfate and magnesium sulfate oral solution were administered orally (gavage) to rats and dogs up to 28 days up to a maximum daily dose of 5 grams/kg/day (approximately 0.9 and 3 times for rats and dogs, respectively, the recommended human dose of 44 grams/day or 0.89 grams/kg based on the body surface area). In rats, the sulfate salts caused diarrhea and electrolyte and metabolic changes, including hypochloremia, hypokalemia, hyponatremia, lower serum osmolality, and high serum bicarbonate. Significant renal changes included increased fractional sodium excretion, increased urinary sodium and potassium excretion, and alkaline urine in both males and females. In addition, creatinine clearance was significantly decreased in females at the highest dose. No microscopic renal changes were seen. In dogs, the sulfate salts caused emesis, excessive salivation, excessive drinking of water, and abnormal excreta (soft and/or mucoid feces and/or diarrhea) and increased urine pH and sodium excretion. 

Adults

The colon cleansing efficacy of sodium sulfate, potassium sulfate and magnesium sulfate oral solution was evaluated in a randomized, single-blind, active-controlled, multicenter study in adult patients scheduled to have a colonoscopy. There were 363 adult patients included in the efficacy analysis. Patients ranged in age from 20 to 84 years (mean age 55 years) and 54% were female. Race distribution was 86% Caucasian, 9% African-American, and 5% other.

Patients were randomized to one of the following two colon preparation regimens: sodium sulfate, potassium sulfate and magnesium sulfate oral solution or a marketed polyethylene glycol (PEG) plus electrolytes bowel preparation. In the Study sodium sulfate, potassium sulfate and magnesium sulfate oral solution was administered as a split-dose (two-day) regimen. The PEG bowel prep was also given as a split-dose preparation according to its labeled instructions. Patients receiving sodium sulfate, potassium sulfate and magnesium sulfate oral solution were limited to a light breakfast followed by clear liquids on the day prior to the day of colonoscopy; patients receiving the PEG bowel prep were allowed to have a normal breakfast and a light lunch, followed by clear liquids.

The primary efficacy endpoint was the proportion of patients with successful colon cleansing as assessed by the colonoscopists, who were not informed about the type of preparation received, as shown in Table 3. In the study, no clinically or statistically significant differences were seen between the group treated with sodium sulfate, potassium sulfate and magnesium sulfate oral solution and the group treated with the PEG bowel prep.

Table 3: Proportion of Adult Patients with Successful Colon Cleansing Response Rates

¹ Responders were patients whose colon preparations were graded excellent (no more than small bits of adherent feces/fluid) or good (small amounts of feces or fluid not interfering with the exam) by the colonoscopist.

²Does not equal difference in tabled responder rates due to rounding effects.
