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

Moviprep, an osmotic laxative used for bowel cleansing, is indicated for:

• Colonoscopy preparation: clears the colon to allow clear visualisation during colonoscopy.
• Sigmoidoscopy preparation: cleans the distal colon for safe sigmoidoscopic examination.
• Pre‑operative bowel cleansing: prepares the intestine before colorectal surgery to reduce infection risk.

• Moviprep creates an osmotic gradient in the intestinal lumen by delivering high concentrations of non‑absorbable solutes such as macrogol, sodium sulfate, and electrolytes. This gradient retains water within the gut, increasing intraluminal volume and stimulating peristalsis, which results in thorough bowel evacuation and cleansing.

Moviprep may cause a range of adverse reactions.

Common Side Effects

• Nausea: mild to moderate feeling of sickness.
• Abdominal discomfort: cramping or pain in the stomach area.
• Bloating and flatulence: excess gas production.
• Vomiting: occasional expulsion of stomach contents.
• Thirst: increased desire for fluids.
• Mild electrolyte imbalance: slight changes in sodium or potassium levels.

Serious or Rare Side Effects

• Severe dehydration: marked loss of body fluids requiring medical attention.
• Significant electrolyte disturbances: dangerous shifts in potassium or sodium that can affect heart rhythm.
• Acute renal impairment: sudden decline in kidney function.
• Severe abdominal pain: intense, persistent pain.
• Allergic reactions: rash, itching, swelling, or anaphylaxis.

Before using Moviprep, consider the following precautions:

• Assess renal function: evaluate kidney health to avoid fluid overload.
• Monitor electrolytes: check serum sodium and potassium levels before and after preparation.
• Correct dehydration: ensure adequate hydration status prior to administration.
• Use cautiously in cardiac disease: patients with heart failure may be sensitive to fluid shifts.
• Pregnancy and lactation: safety not established; discuss risks with a healthcare professional.
• Store at ambient temperature: keep in the original container, protect from moisture and direct sunlight.

Moviprep can interact with other medicines, requiring attention to the following:

Major Interactions (Avoid)

• Concomitant potassium‑sparing diuretics: risk of hyperkalaemia.
• Use with other osmotic laxatives: may cause excessive fluid loss.
• Simultaneous IV electrolyte solutions: can exacerbate electrolyte imbalance.

Moderate Interactions (Monitor Closely)

• Antacids containing magnesium: may increase gastrointestinal irritation.
• ACE inhibitors or ARBs: monitor renal function and electrolytes.
• NSAIDs: heightened risk of renal impairment when combined with bowel cleansing.
