Moviprep (Ascorbic Acid, Sodium Ascorbate, Potassium Chloride, Sodium Chloride, Sodium Sulfate Anhydrous, Macr)

Moviprep is an osmotic laxative used for bowel cleansing prior to endoscopic procedures.

• Colonoscopy: provides thorough cleansing of the colon to enable clear visualization during the procedure.
• Sigmoidoscopy: clears the sigmoid colon and rectum to facilitate accurate examination.
• Pre‑operative bowel preparation: empties the intestinal tract before certain abdominal surgeries to reduce infection risk.

• Moviprep creates an osmotic gradient in the intestinal lumen by delivering high concentrations of ascorbic acid, sodium ascorbate, potassium chloride, sodium chloride and sodium sulfate. The resulting osmotic pressure draws water into the bowel, increasing luminal volume and stimulating peristalsis, which leads to rapid evacuation of intestinal contents and effective cleansing of the colon. This process also helps to dilute intestinal electrolytes, facilitating safe passage of stool.

Moviprep may cause a range of adverse reactions, most of which are mild and transient.

Common Side Effects

• Nausea: mild feeling of queasiness.
• Abdominal discomfort: cramping or pain in the stomach area.
• Bloating: sensation of abdominal fullness.
• Flatulence: increased gas production.
• Thirst: increased desire to drink fluids.
• Mild electrolyte changes: slight alterations in sodium or potassium levels.

Serious or Rare Side Effects

• Severe dehydration: excessive loss of body fluids.
• Significant electrolyte imbalance: marked hypo‑ or hyper‑kalemia.
• Acute renal impairment: sudden reduction in kidney function.
• Severe abdominal pain: intense, persistent pain.
• Allergic reaction: rash, itching, swelling, or difficulty breathing.
• Colonic perforation: rare tear in the colon wall.

Before prescribing Moviprep, clinicians should consider several precautionary measures to minimize risks.

• Assess renal function: evaluate kidney health to avoid worsening impairment.
• Monitor electrolytes: check sodium and potassium levels before and after use.
• Adjust for severe constipation: consider alternative regimens if baseline bowel motility is low.
• Avoid in known hypersensitivity: do not use in patients allergic to any component.
• Use with caution in the elderly: older patients may be more susceptible to fluid shifts.
• Store at ambient temperature: keep in the original packaging, protect from moisture and heat.

Moviprep can interact with other medicines, affecting fluid and electrolyte balance or renal function.

Major Interactions (Avoid)

• Loop diuretics: combined use may cause profound electrolyte loss and dehydration.
• High‑dose potassium supplements: risk of hyperkalemia when combined.
• ACE inhibitors or ARBs: may increase risk of renal dysfunction.
• NSAIDs: can exacerbate renal impairment and fluid imbalance.

Moderate Interactions (Monitor Closely)

• Anticholinergic agents: may reduce the laxative efficacy.
• Opioid analgesics: can slow gastrointestinal motility, diminishing bowel cleansing.
• Antacids containing sodium or potassium: may alter electrolyte composition.
