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

Moviprep is an osmotic laxative used for bowel preparation in gastrointestinal endoscopic procedures.

• Colonoscopy: provides thorough cleansing of the colon to enable clear visualization during the procedure.
• Sigmoidoscopy: clears the distal colon and rectum to facilitate examination of the sigmoid colon.
• Pre‑procedure imaging: prepares the bowel for radiologic studies such as CT colonography where a clean colon is required.

• Moviprep contains polyethylene glycol 3350 combined with electrolytes. The polymer is poorly absorbed and retains water in the intestinal lumen by osmotic activity. The added sodium, potassium, chloride and sulfate ions maintain electrolyte balance while drawing fluid into the bowel, producing a rapid, volume‑dependent laxation that evacuates colonic contents, achieving the required cleansing for endoscopic evaluation.

Moviprep may cause a range of adverse reactions, most of which are related to its osmotic activity and electrolyte composition.

Common Side Effects

• Nausea: mild to moderate feeling of sickness.
• Abdominal cramping: intermittent pain or discomfort in the abdomen.
• Diarrhea: loose, watery stools during the cleansing process.
• Bloating: sensation of abdominal fullness or gas.

Serious or Rare Side Effects

• Severe dehydration: marked loss of body fluids leading to dizziness or low blood pressure.
• Electrolyte imbalance: abnormal serum levels of sodium, potassium or chloride.
• Allergic reaction: rash, itching, swelling, or difficulty breathing.
• Renal impairment: worsening kidney function in susceptible individuals.

When using Moviprep, several precautions should be observed to ensure safety and effectiveness.

• Assess renal function: evaluate kidney status before administration, especially in patients with known impairment.
• Review electrolyte status: check serum sodium and potassium levels to avoid significant shifts.
• Fluid intake: encourage adequate oral fluids during preparation to reduce risk of dehydration.
• Contraindications: avoid use in patients with known bowel obstruction or perforation.
• Pregnancy and lactation: use only if the potential benefit justifies the potential risk, as safety data are limited.
• Store at ambient temperature: keep below 25 °C, in the original packaging, protected from moisture and direct sunlight.

Moviprep can interact with other medicines, primarily through its effect on fluid and electrolyte balance.

Major Interactions (Avoid)

• Loop diuretics: may exacerbate electrolyte loss and dehydration.
• Sodium‑containing laxatives: increase risk of fluid overload and electrolyte disturbances.
• Antihypertensive agents: potential for enhanced hypotensive effect due to volume depletion.

Moderate Interactions (Monitor Closely)

• ACE inhibitors or ARBs: monitor blood pressure and renal function during preparation.
• Anticoagulants: assess bleeding risk if severe diarrhea leads to mucosal irritation.
• Oral rehydration solutions: coordinate timing to maintain appropriate electrolyte balance.
