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

Moviprep, an osmotic laxative, is employed to prepare the bowel before endoscopic examinations.

• Colonoscopy: provides thorough bowel cleansing to enable clear visualization of the colon during the procedure.
• Sigmoidoscopy: clears the distal colon and rectum to facilitate accurate assessment.
• Capsule endoscopy preparation: ensures adequate intestinal clearance for optimal capsule transit and imaging.

• Moviprep contains polyethylene glycol, a high‑molecular‑weight polymer that remains largely unabsorbed in the gastrointestinal tract. It creates an osmotic gradient that draws water into the intestinal lumen, increasing fluid volume and softening stool, which accelerates rapid bowel evacuation and clears the colon for diagnostic procedures.

Common Side Effects

• Nausea: mild to moderate feeling of sickness.
• Abdominal bloating: sensation of fullness or distension.
• Cramping: intermittent abdominal pain.
• Vomiting: occasional expulsion of stomach contents.
• Thirst: increased desire for fluids.
• Mild electrolyte changes: transient shifts in sodium or potassium levels.

Serious or Rare Side Effects

• Severe dehydration: marked loss of body water requiring medical attention.
• Significant electrolyte imbalance: dangerous shifts in sodium, potassium, or chloride.
• Renal impairment: reduced kidney function, especially in susceptible patients.
• Allergic reaction: rash, itching, or swelling.
• Colonic perforation: rare but life‑threatening injury to the bowel wall.

Before using Moviprep, consider the following safety measures.

• Renal function assessment: evaluate kidney health to avoid fluid overload.
• Electrolyte monitoring: check serum electrolytes in patients at risk.
• Adequate hydration: ensure sufficient fluid intake during preparation.
• Contraindication in obstruction: do not use if intestinal blockage is present.
• Avoid in severe dehydration: postpone until rehydration is achieved.
• Store at ambient temperature: keep in the original packaging, protect from moisture and direct sunlight.

Moviprep may interact with other medicines; review the following.

Major Interactions (Avoid)

• Other osmotic laxatives: combined use can cause excessive fluid loss.
• Loop diuretics: heightened risk of electrolyte disturbances.
• NSAIDs: increased potential for renal impairment.
• ACE inhibitors or ARBs: may exacerbate kidney function changes.

Moderate Interactions (Monitor Closely)

• Antacids: may alter gastrointestinal pH affecting preparation.
• Mineral supplements (e.g., calcium, magnesium): could affect electrolyte balance.
• Certain antibiotics (e.g., tetracyclines, quinolones): absorption may be reduced.
