Macro P

Macrogol 4000, the active ingredient in Macro P, is an excipient presented as an oral powder for oral use. It functions as an osmotic laxative and bowel‑preparation agent in adults and children when formulated appropriately.

GNH USA supplies Macro P as a licensed, GDP‑compliant international pharmaceutical supplier serving hospitals, pharmacies and clinics worldwide.

Macro P (Macrogol 4000) is employed in conditions where osmotic laxation or bowel cleansing is required.

- Constipation: softens stool and promotes bowel movements by retaining water in the intestinal lumen. - Bowel preparation before diagnostic procedures: facilitates rapid evacuation of the colon for colonoscopy or imaging. - Chronic idiopathic constipation in adults: helps achieve regular bowel habits when other measures are insufficient.

Macrogol 4000 is generally well tolerated, but adverse reactions can occur.

Common Side Effects: - Abdominal bloating: sensation of fullness or swelling in the abdomen. - Flatulence: increased intestinal gas production. - Nausea: mild to moderate feeling of queasiness. - Abdominal cramping: intermittent painful contractions. - Diarrhoea: loose stools occurring with higher doses. - Electrolyte imbalance: mild changes in sodium or potassium levels.

Serious or Rare Side Effects: - Severe dehydration: excessive fluid loss leading to dizziness or low blood pressure. - Marked electrolyte disturbances: significant hyponatraemia or hypokalaemia. - Allergic reaction: rash, itching, or swelling of the face and throat. - Severe abdominal pain: persistent or worsening pain requiring medical attention. - Rectal bleeding: uncommon but may indicate mucosal irritation. - Intestinal perforation: extremely rare, usually in the presence of obstruction.

When using Macro P, consider the following safety measures.

- Assess hydration status: ensure adequate fluid intake to prevent dehydration. - Monitor electrolyte balance: especially in elderly, renal‑impaired, or critically ill patients. - Avoid in intestinal obstruction: risk of increased pressure and perforation. - Use cautiously in inflammatory bowel disease: may exacerbate symptoms. - Pregnancy and breastfeeding: consult a healthcare professional before use. - Store at ambient temperature: keep in the original packaging, protect from moisture and direct sunlight.

Macrogol 4000 may interact with other orally administered agents.

Major Interactions (Avoid): - Concurrent oral electrolyte solutions: can cause severe electrolyte imbalance. - High‑dose diuretics: may exacerbate fluid loss and dehydration.

Moderate Interactions (Monitor Closely): - Antacids: may reduce the laxative efficacy of macrogol. - Oral antibiotics: absorption may be altered, affecting therapeutic levels. - Other osmotic laxatives: combined use can increase risk of dehydration. - Oral iron supplements: may experience reduced absorption. - Vitamin C preparations: high doses can enhance osmotic effect, leading to diarrhoea.
