Sutab Warnings/Precautions

Warnings/Precautions

Maintain adequate hydration. Correct fluid and electrolyte abnormalities before therapy. Renal impairment; monitor baseline and post-colonoscopy electrolytes, creatinine, BUN. History of QT prolongation, uncontrolled arrhythmias, recent MI, unstable angina, CHF, or cardiomyopathy: increased risk of arrhythmias; consider ECGs at pre-dose and post-colonoscopy. History of seizures. Hyponatremia. Inflammatory bowel disease. Colonic mucosal ulcerations. Ischemic colitis. Severe ulcerative colitis. Elderly. Pregnancy. Nursing mothers.

Warnings/Precautions

Serious Fluid and Electrolyte Abnormalities 

  • Advise patients to hydrate before, during, and after using Sutab.

  • Consider performing post-colonoscopy lab tests (electrolytes, creatinine, and BUN) if significant vomiting or signs of dehydration develop.

  • Correct fluid and electrolyte abnormalities prior to treatment.

  • Exercise caution in patients with conditions, or who are using medications, that increase the risk for fluid and electrolyte disturbances and may increase the risk for adverse events of seizure, arrhythmias, and renal impairment.

Cardiac Arrhythmias

  • Rare reports of serious arrhythmias associated with the use of ionic osmotic laxative products for bowel preparation have occurred.

  • Use caution in patients at increased risk for arrhthymias (eg, history of prolonged QT, uncontrolled arrhythmias, recent myocardial infarction, unstable angina, congestive heart failure, or cardiomyopathy).

  • For patients at increased risk for serious cardiac arrhthymias, consider pre-dose and post-colonoscopy ECG.

Seizures

  • 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 have occurred.

  • Exercise caution in patients with a history of seizures and in patients at increased risk of seizure (eg, concomitant use with medications that lower the seizure threshold [eg, tricyclics]), patients withdrawing from alcohol or benzodiazepines, or patients with known or suspected hyponatremia.

Use in Patients with Risk of Renal Injury 

  • Exercise caution in patients with impaired renal function or patients taking concomitant medications that may affect renal function (eg, diuretics, angiotensin converting enzyme inhibitors, angiotensin receptor blockers, or non-steroidal anti-inflammatory drugs). These patients may be at risk for renal injury.

  • Advise these patients to adequately hydrate with Sutab.

Colonic Mucosal Ulcerations and Ischemic Colitis

  • Colonic mucosal aphthous ulcerations may occur, along with more serious cases of ischemic colitis requiring hospitalization. Increased risk for these reactions with concomitant use of stimulant laxatives with Sutab.

  • Exercise caution in patients with known or suspected inflammatory bowel disease (IBD).

Use in Patients with Significant Gastrointestinal Disease

  • Perform appropriate diagnostic studies if GI obstruction or perforation is suspected.

  • Use caution in patients with severe active ulcerative colitis.

Hypersensitivity Reactions  

  • Serious hypersensitivity reactions, including anaphylaxis, angioedema, dyspnea, rash, pruritus, and urticaria have been reported.

  • Seek immediate medical care if signs and symptoms of anaphylaxis develop.

Risk of Gastrointestinal Complications with Ingestion of Desiccant

  • Each Sutab bottle contains a desiccant. Remove and discard the desiccant from both bottles of Sutab the evening prior to the colonoscopy.

Pregnancy Considerations

No available data on the use of Sutab in pregnant women to evaluate for a drug-associated risk of major birth defects, miscarriage, or adverse maternal or fetal outcomes.

Nursing Mother Considerations

No available data on the presence of Sutab in human or animal milk, the effects on the breastfed child, or the effects on milk production.  

Consider the developmental and health benefits of breastfeeding 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 Considerations

Safety and effectiveness have not been established.

Renal Impairment Considerations

Use caution in patients with renal impairment or concomitant use with medications that affect renal function.

Advise patients to adequately hydrate prior to, during, and after use of Sutab.

Sutab Pharmacokinetics

Elimination

Fecal.

Sutab Interactions

Interactions

Caution with concomitant diuretics, ACE inhibitors, ARBs, NSAIDs; may affect renal function. Drugs that may lower the seizure threshold (eg, tricyclic antidepressants), alcohol or benzodiazepine withdrawal: may increase risk of seizures. Caution with drugs that may increase risk for fluid or electrolyte disturbances, arrhythmias or QT prolongation. Administer oral medications at least 1hr before starting each dose of Sutab. Administer tetracycline and fluoroquinolone antibiotics, iron, digoxin, chlorpromazine, and penicillamine at least 2hrs before and not less than 6hrs after Sutab to avoid chelation with magnesium. Avoid concomitant stimulant laxatives (eg, bisacodyl, sodium picosulfate).

Sutab Adverse Reactions

Adverse Reactions

Nausea, abdominal distension, vomiting, upper abdominal pain; electrolyte abnormalities, renal injury.

Sutab Clinical Trials

Clinical Trials

The approval of Sutab was based on 2 active-controlled trials that included adults undergoing colonoscopy for colorectal cancer screening and surveillance or diagnostic colonoscopy. Both Sutab and the active comparators were administered according to a split-dose regimen.

The primary endpoint of both trials was the proportion of patients with successful colon cleansing, as assessed by the blinded colonoscopist utilizing a 4-point scale. Success was defined as an overall cleansing assessment of “good” (feces and fluid requiring washing and suctioning, but still achieves clear visualization of the entire colonic mucosa) or “excellent” (no more than small bits of feces/fluid which can be suctioned easily; achieves clear visualization of the entire colonic mucosa).

In both studies, Sutab was noninferior to the comparator. 

  • 92% of patients (Study 1: 257/278; Study 2: 175/190) achieved overall cleansing success vs 89% of patients (241/270) who received polyethylene glycol 3350, sodium sulfate, sodium chloride, potassium chloride, sodium ascorbate and ascorbic acid for oral solution (active comparator in Study 1) and 88% of patients (174/198) of patients who received sodium picosulfate, magnesium oxide, and anhydrous citric acid for oral solution (active comparator in Study 2).
