Sutab Dosage and Administration

Preparation and Administration Instructions


  • Correct fluid and electrolyte abnormalities before treatment with Sutab [see Warnings and Precautions ( 5.1)]
  • Administration of two doses of Sutab (24 tablets) are required for a complete preparation for colonoscopy. Twelve (12) tablets are equivalent to one dose.
  • Water must be consumed with each dose of Sutab and additional water must be consumed after each dose.
  • Consume a low residue breakfast on the day before colonoscopy, followed by clear liquids up to 2 hours prior to colonoscopy.
  • Do not drink milk or eat or drink anything colored red or purple.
  • Do not drink alcohol.
  • Do not take other laxatives while taking Sutab.
  • Do not take oral medications within 1 hour of starting each dose of Sutab.
  • If taking tetracycline or fluoroquinolone antibiotics, iron, digoxin, chlorpromazine, or penicillamine, take these medications at least 2 hours before and not less than 6 hours after administration of each dose of Sutab.
  • Stop consumption of all fluids at least 2 hours prior to the colonoscopy.

Split-Dose (2-Day) Regimen

The recommended Split-Dose regimen for adults consists of two doses of Sutab: the first dose during the evening prior to colonoscopy and the second dose the next day, during the morning of the colonoscopy.

Instruct patients:

Dose 1 – On the day prior to colonoscopy:

  • A low residue breakfast may be consumed. Examples of low residue foods are eggs, white bread, cottage cheese, yogurt, grits, coffee, tea.
  • After breakfast, only clear liquids may be consumed until after the colonoscopy.
  • Early in the evening prior to colonoscopy, open one bottle of 12 tablets.
  • Fill the provided container with 16 ounces of water (up to the fill line). Swallow each tablet with a sip of water and drink the entire amount over 15 to 20 minutes.
  • Approximately one hour after the last tablet is ingested, fill the provided container a second time with 16 ounces of water (up to the fill line) and drink the entire amount over 30 minutes.
  • Approximately 30 minutes after finishing the second container of water, fill the provided container again with 16 ounces of water (up to the fill line) and drink the entire amount over 30 minutes.
  • If patients experience preparation-related symptoms (e.g. nausea, bloating, cramping), pause or slow the rate of drinking the additional water until symptoms diminish.

Dose 2 - Day of colonoscopy:

  • Continue to consume only clear liquids until after the colonoscopy.
  • The morning of colonoscopy (5 to 8 hours prior to the colonoscopy and no sooner than 4 hours from starting Dose 1), open the second bottle of 12 tablets.
  • Fill the provided container with 16 ounces of water (up to the fill line). Swallow each tablet with a sip of water and drink the entire amount over 15 to 20 minutes.
  • Approximately one hour after the last tablet is ingested, fill the provided container a second time with 16 ounces of water (up to the fill line) and drink the entire amount over 30 minutes.
  • Approximately 30 minutes after finishing the second container of water, fill the provided container again with 16 ounces of water (up to the fill line) and drink the entire amount over 30 minutes.
  • If patients experience preparation-related symptoms (e.g. nausea, bloating, cramping), pause or slow the rate of drinking the additional water until symptoms diminish.
  • Complete all Sutab tablets and water at least two hours prior to colonoscopy.

Dosage Forms and Strengths

Tablets: 1.479 g sodium sulfate, 0.225 g magnesium sulfate, and 0.188 g potassium chloride. The tablets are white to off-white, film coated, oblong, and biconvex with flat sides, debossed with S24 on one side.

Contraindications

Sutab is contraindicated in the following conditions:

  • Gastrointestinal obstruction or ileus [see Warnings and Precautions ( 5.6)
  • Bowel perforation [see Warnings and Precautions ( 5.6)
  • Toxic colitis or toxic megacolon
  • Gastric retention

Warnings and Precautions

Serious Fluid and Electrolyte Abnormalities

Advise all patients to hydrate adequately before, during, and after the use of Sutab. If a patient develops significant vomiting or signs of dehydration after taking Sutab, 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 Sutab. Use Sutab 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)]

Cardiac Arrhythmias

There have been rare reports of serious arrhythmias associated with the use of ionic osmotic laxative products for bowel preparation. Use caution when prescribing Sutab 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.

Seizures

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 Sutab 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 in Patients with Risk of Renal Injury

Use Sutab 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 Sutab and consider performing baseline and post-colonoscopy laboratory tests (electrolytes, creatinine, and BUN) in these patients [see Use in Specific Populations ( 8)] .

Colonic Mucosal Ulcerations and Ischemic Colitis

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 Sutab 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).

Use in Patients with Significant Gastrointestinal Disease

If gastrointestinal obstruction or perforation is suspected, perform appropriate diagnostic studies to rule out these conditions before administering Sutab [see Contraindications ( 4)] .

Use in caution in patients with severe active ulcerative colitis.

Adverse Reactions

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

  • Serious Fluid and Electrolyte Abnormalities [see Warnings and Precautions ( 5.1)]
  • Cardiac Arrhythmias [see Warnings and Precautions ( 5.2)]
  • Seizures [see Warnings and Precautions ( 5.3)]
  • 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)]

Clinical Trials Experience

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.

The safety of Sutab was evaluated in two randomized, parallel group, multicenter, investigator blinded clinical trials in 941 adult patients undergoing colonoscopy. The active comparators were polyethylene glycol 3350, sodium sulfate, sodium chloride, potassium chloride, ascorbic acid and sodium ascorbate for oral solution in Study 1 and sodium picosulfate, magnesium oxide, and anhydrous citric acid for oral solution in Study 2 [see Clinical Studies ( 14)] .

Adverse Gastrointestinal Reactions Reported by Symptom Questionnaire
In Studies 1 and 2, patients were queried for selected gastrointestinal adverse reactions of stomach cramping (upper abdominal pain), stomach bloating (abdominal distention), nausea and vomiting using a standard questionnaire following completion of study drug and prior to colonoscopy on the day of colonoscopy. Patients reporting selected gastrointestinal symptom(s) rated the intensity as mild, moderate or severe.

A total of 52% (287/552) of patients in Study 1 and 52% (202/389) in Study 2 reported at least one selected gastrointestinal adverse reaction when queried using the standard questionnaire. Tables 1 and 2 show results for each gastrointestinal adverse reaction reported by patients using the standard questionnaire, including severity.

Shifts in serum electrolytes from normal at baseline to above the upper end of normal following study drug on the day of colonoscopy in at least 2% of patients in either treatment arm and at least 2% greater in patients treated with Sutab than treated with comparator in either Study 1 or Study 2 were: magnesium (27% Sutab and 5% comparator in Study 1), and serum osmolality (44% Sutab and 28% comparator in Study 2). These changes were transient and resolved without intervention.

Renal Function Parameters
Decreases in creatinine clearance and increases in blood urea nitrogen (BUN) were reported in less than 1% of patients in both Sutab and comparator arms in both trials.

Drug Interactions

Drugs That May Increase Risks of Fluid and Electrolyte Abnormalities

Use caution when prescribing Sutab to patients taking medications that increase the risk of fluid and electrolyte disturbances or may increase the risk of adverse events of seizure, arrhythmias, and prolonged QT in the setting of fluid and electrolyte abnormalities [see Warnings and Precautions ( 5.1, 5.2, 5.3, 5.4)] .

Potential for Reduced Drug Absorption

Sutab can reduce the absorption of other co-administered drugs [see Dosage and Administration ( 2.1)] :

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

Stimulant Laxatives

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

USE IN SPECIFIC POPULATIONS

Pregnancy

Risk Summary

There are no available data on Sutab use in pregnant women to evaluate for a drug-associated risk of major birth defects, miscarriage, or adverse maternal or fetal outcomes. No reproduction or developmental studies in animals have been conducted with sodium sulfate, magnesium sulfate, and potassium chloride (Sutab).

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.

Lactation

Risk Summary

There are no available data on the presence of Sutab in human or animal milk, the effects of 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 Sutab and any potential adverse effects on the breastfed child from Sutab or from the underlying maternal condition.

Pediatric Use

Safety and effectiveness in pediatric patients have not been established.

Geriatric Use

Of the 471 patients who received Sutab in pivotal clinical trials, 150 (32%) were 65 years of age or older, and 25 (5%) were 75 years of age or older. No differences in safety or effectiveness of Sutab were observed between geriatric patients and younger patients. 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)] .

Renal Impairment

Use Sutab 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 Sutab and consider performing baseline and post-colonoscopy laboratory tests (electrolytes, creatinine, and BUN) in these patients [see Warning and Precautions ( 5.4)] .

Overdosage

Overdosage of more than the recommended dose of Sutab 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.

Sutab - Clinical Pharmacology

Mechanism of Action

The primary mode of action is osmotic action of sodium sulfate and magnesium sulfate, which induce a laxative effect. The physiological consequence is increased water retention in the lumen of the colon, resulting in loose stools.

Pharmacokinetics

Absorption
After the oral administration of Sutab to patients in clinical studies, the median serum sulfate concentration increased by about 2.5-fold at 5 to 8 hours post Dose 2 (0.61 mmol/L) compared to baseline (0.25 mmol/L) and returned to baseline by 24 to 48 hours after colonoscopy.

Elimination
Fecal excretion is the primary route of sulfate elimination.

Use in Specific Populations
Patients with Renal Impairment
The disposition of sulfate after ingestion of a sulfate-based product containing sodium sulfate, potassium sulfate, and magnesium sulfate similar to Sutab 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 Cmax 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 a sulfate-based product containing sodium sulfate, potassium sulfate, and magnesium sulfate similar to Sutab was also studied in patients (N=6) with mild-moderate hepatic impairment (Child-Pugh grades A and B). Systemic exposure of serum sulfate (AUC and Cmax) 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.

Nonclinical Toxicology

Animal Toxicology and/or Pharmacology

Animal toxicology studies with sodium sulfate, magnesium sulfate, and potassium chloride (Sutab) have not been conducted. Sulfate salts of sodium, potassium, and magnesium, 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 Sutab human dose of 45.4 grams/day or 0.86 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 male 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.

Clinical Studies

The colon cleansing efficacy of Sutab was evaluated in two randomized, single-blind, active-controlled, multicenter trials (Study 1 and Study 2). These trials included adult subjects undergoing colonoscopy for colorectal cancer screening and surveillance, or diagnostic colonoscopy, including subjects with abdominal pain, diarrhea, constipation and non-severe inflammatory bowel disease.

In Study 1 (BLI4700-301; NCT 03404401), 548 adult patients were included in the efficacy analysis. Patients ranged in age from 19 to 84 years (median age 59 years) and 56% were female. Racial distribution was 78% Caucasian, 16% African-American, and 11% Hispanic or Latino. Patients were randomized to one of the following two colon preparation regimens: Sutab or polyethylene glycol 3350, sodium sulfate, sodium chloride, potassium chloride, ascorbic acid and sodium ascorbate for oral solution. Both preparations were administered according to a split-dose regimen [see Dosage and Administration ( 2.2)] . Patients receiving Sutab were limited to a low residue breakfast followed by clear liquids on the day prior to the day of colonoscopy; patients receiving the comparator bowel prep were allowed to have a normal breakfast and a light lunch, followed by clear liquids and/or yogurt for dinner. Approximately 97% of patients in the study completed both doses of preparation (98% of Sutab patients and 95% of comparator patients).

In Study 2 (BLI4700-302; NCT 03261960), 388 adult patients were included in the efficacy analysis. Patients ranged in age from 23 to 83 years (median age 58 years) and 58% were female. Racial distribution was 94% Caucasian, 9% Hispanic or Latino, and 5% African-American. Patients were randomized to one of the following two colon preparation regimens: Sutab or sodium picosulfate, magnesium oxide, and anhydrous citric acid for oral solution. Both preparations were administered according to a split-dose regimen [see Dosage and Administration ( 2.2)] . Patients receiving Sutab were limited to a low residue breakfast followed by clear liquids on the day prior to the day of colonoscopy; patients receiving the comparator bowel prep were only allowed clear liquids on the day prior to colonoscopy. Approximately 98% of patients in the study completed both doses of preparation (98% of Sutab patients and 99% of comparator patients).

The primary efficacy endpoint in each trial was the proportion of patients with successful colon cleansing, as assessed by the blinded colonoscopist utilizing the four-point scaled described below. Success was defined as an overall cleansing assessment of 3 (Good) or 4 (Excellent).

Score Grade Description
1 Poor Large amount of fecal residue, additional bowel preparation required.
2 Fair Enough feces even after washing and suctioning to prevent clear visualization of the entire colonic mucosa.
3 Good Feces and fluid requiring washing and suctioning, but still achieves clear visualization of the entire colonic mucosa.
4 Excellent No more than small bits of feces/fluid which can be suctioned easily; achieves clear visualization of the entire colonic mucosa.

Results for the primary endpoint in Studies 1 and 2 are shown in Table 3. In both trials, Sutab was non-inferior to the comparator.

tablets, for oral use

Read and understand these Medication Guide Instructions at least 2 days before your colonoscopy and again before you start taking Sutab.

What is the most important information I should know about Sutab?

Sutab and other bowel preparations can cause serious side effects, including:

Serious loss of body fluid (dehydration) and changes in blood salts (electrolytes) in your blood.


These changes can cause:

  • abnormal heartbeats that can cause death.
  • seizures. This can happen even if you have never had a seizure.
  • kidney problems.

Your chance of having fluid loss and changes in body salts with Sutab is higher if you:

  • have heart problems.
  • have kidney problems.
  • take water pills (diuretics) or non-steroidal anti-inflammatory drugs (NSAIDs).

Tell your healthcare provider right away if you have any of these symptoms of a loss of too much body fluid (dehydration) while taking Sutab:

  • vomiting • urinating less often than normal
  • dizziness • headache

See “What are the possible side effects of Sutab?” for more information about side effects.

What is Sutab?


Sutab is a prescription medicine used by adults to clean the colon before a colonoscopy. Sutab cleans your colon by causing you to have diarrhea. Cleaning your colon helps your healthcare provider see the inside of your colon more clearly during your colonoscopy.


It is not known if Sutab is safe and effective in children.

Do not take Sutab if your healthcare provider has told you that you have:

  • a blockage in your bowel (obstruction) or a problem with food moving too slowly through your intestines (ileus)
  • an opening in the wall of your stomach or intestine (bowel perforation)
  • a very dilated intestine (toxic colitis or toxic megacolon)
  • problems with food and fluid emptying from your stomach (gastric retention)

Before taking Sutab, tell your healthcare provider about all of your medical conditions, including if you:

  • have heart problems.
  • have stomach or bowel problems including ulcerative colitis.
  • have problems with swallowing or gastric reflux.
  • have a history of seizures.
  • are withdrawing from drinking alcohol or from taking benzodiazepines.
  • have a low blood salt (sodium) level.
  • have kidney problems.
  • are pregnant. It is not known if Sutab will harm your unborn baby. Talk to your healthcare provider if you are pregnant.
  • are breastfeeding or plan to breastfeed. It is not known if Sutab passes into your breast milk. You and your healthcare provider should decide if you will take Sutab while breastfeeding.

T ell your healthcare provider about all the medicines you take, including prescription and over-the-counter medicines, vitamins, and herbal supplements.


Sutab may affect how other medicines work. Medicines taken by mouth may not be absorbed properly when taken within 1 hour before the start of each dose of Sutab.


Especially tell your healthcare provider if you take:

  • medicines for blood pressure or heart problems.
  • medicines for kidney problems.
  • medicines for seizures.
  • water pills (diuretics).
  • non-steroidal anti-inflammatory drugs (NSAIDs).
  • medicines for depression or other mental health problems.
  • laxatives. Do not take other laxatives while taking Sutab.

The following medicines should be taken at least 2 hours before starting each dose of Sutab and not less than 6 hours after taking each dose of Sutab:
• tetracycline • iron • chlorpromazine
• fluoroquinolone antibiotics • digoxin • penicillamine

Ask your healthcare provider or pharmacist for a list of these medicines if you are not sure if you are taking any of the medicines listed above.
