1. What Osmosol® 20 is and what it is used for?
Osmosol® 20 is a clear, almost colorless and sterile solution of Mannitol. Each 100ml of Osmosol® 20 contains Mannitol BP 20g. Administered parenterally, Osmosol® 20 raises the osmotic pressure of the plasma, thus drawing water out of body tissues and produces an osmotic diuresis. Osmosol® 20 is principally used by IV infusion as an osmotic diuretic to preserve renal function in acute renal failure and to reduce raised intracranial and intraocular pressure. Osmosol® 20 is also used as an irrigating solution to prevent hemolysis and hemoglobin buildup during transurethral prostatic resection. It is useful in the management of acute drug poisoning where a route of elimination is through kidney. Besides these, it is also used in symptomatic relief of edema, reperfusion injury, termination of pregnancy, and bowel preparation.
