Molative (Sodium Hydrogen Carbonate, Potassium Chloride, Sodium Chloride, Macrogol 3350)

Molative is used as an oral electrolyte‑laxative for bowel preparation and constipation management.

• Colonoscopy preparation: facilitates rapid and complete bowel cleansing prior to the procedure.
• Acute constipation: promotes soft stool formation and bowel movement in adults with occasional constipation.
• Pre‑operative bowel emptying: clears the intestinal tract before abdominal surgery to reduce infection risk.
• Electrolyte repletion: supplies sodium, potassium and chloride to support fluid balance during bowel cleansing.

• Molative combines macrogol 3350, an osmotic polymer that retains water in the intestinal lumen, with sodium hydrogen carbonate, sodium chloride and potassium chloride, which increase the osmotic gradient and provide essential electrolytes. The resulting high‑volume, isotonic solution draws fluid into the colon, softening stool and stimulating peristalsis, while the carbonate component buffers gastric acidity.

Molative may cause a range of adverse reactions, most of which are related to its osmotic and electrolyte properties.

Common Side Effects

• Nausea: mild to moderate feeling of queasiness.
• Abdominal bloating: sensation of fullness or distension.
• Flatulence: increased intestinal gas.
• Thirst: heightened desire for fluids.
• Headache: occasional mild headache.

Serious or Rare Side Effects

• Severe dehydration: marked loss of body water.
• Electrolyte imbalance: hypernatremia or hypokalemia.
• Allergic reaction: rash, itching or swelling.
• Severe abdominal pain: intense cramping that may indicate complications.
• Colonic perforation: rare but life‑threatening bowel injury.

When using Molative, clinicians should observe several precautionary measures to ensure safety and effectiveness.

• Renal function assessment: evaluate kidney status before initiation.
• Electrolyte monitoring: check serum sodium and potassium during therapy.
• Heart failure caution: avoid in patients with uncontrolled fluid overload.
• Bowel obstruction avoidance: do not use in complete mechanical obstruction.
• Volume limitation: do not exceed the prescribed solution volume.
• Store at ambient temperature: keep in the original pack, protect from moisture and direct sunlight.

Molative can interact with other medicines that affect fluid or electrolyte balance.

Major Interactions (Avoid)

• Other osmotic laxatives: risk of excessive fluid loss and electrolyte disturbance.
• Loop diuretics: may amplify potassium depletion.
• NSAIDs: increased risk of gastrointestinal irritation.

Moderate Interactions (Monitor Closely)

• Antacids: may alter the pH and affect absorption.
• ACE inhibitors: potential additive effect on potassium levels.
• Antihypertensives: monitor blood pressure due to fluid shifts.
