Mannitol

Mannitol, the active ingredient in Mannitol, is an osmotic diuretic presented as an injection solution for intravenous use. It is employed to reduce intracranial pressure, manage acute renal failure, lower intraocular pressure, and promote osmotic diuresis in appropriate clinical settings.

GNH USA supplies Mannitol as a licensed, GDP‑compliant international pharmaceutical supplier serving hospitals, transplant centres, oncology centres, pharmacies, clinics and procurement teams worldwide across multiple regions. The company adheres to stringent quality standards and provides regulatory support for import and distribution.

Mannitol is used as an osmotic diuretic to manage conditions where fluid removal or pressure reduction is required.

Intracranial hypertension: reduces intracranial pressure by creating an osmotic gradient that draws fluid from brain tissue into the vascular compartment. Acute renal failure (oliguric phase): promotes osmotic diuresis to increase urine output and assist in the removal of waste products. Elevated intraocular pressure: lowers intraocular pressure by osmotic movement of water from the eye, aiding in the management of glaucoma emergencies.

Mannitol may be associated with a range of adverse reactions, varying from mild to severe.

Common Side Effects: - Headache: mild to moderate intensity. - Nausea or vomiting: gastrointestinal upset. - Electrolyte imbalance: especially hyponatremia or hyperkalemia. - Transient hypotension: due to rapid plasma expansion. - Pulmonary edema: fluid overload in susceptible patients. - Thirst or dry mouth.

Serious or Rare Side Effects: - Acute renal failure: worsening kidney function. - Severe electrolyte disturbances: profound hyponatremia or hyperkalemia. - Anaphylactic reaction: rare hypersensitivity. - Cardiac arrhythmias: secondary to electrolyte shifts. - Intracranial hemorrhage: if pressure changes abruptly. - Metabolic acidosis: due to accumulation of acid metabolites.

Before using Mannitol, several safety considerations should be observed.

Assess renal function: avoid use in severe renal impairment. Monitor fluid balance: prevent volume overload. Check electrolytes: correct abnormalities prior to infusion. Avoid rapid infusion in patients with cardiac disease. Use with caution in pregnancy: safety not established. Store at 2-8°C: keep refrigerated, protect from light, do not freeze or shake.

Mannitol can interact with other medicines, influencing efficacy or safety.

Major Interactions (Avoid): - Loop diuretics (e.g., furosemide): may exacerbate electrolyte loss. - Insulin or oral hypoglycemics: osmotic shift can affect glucose control. - Nephrotoxic agents (e.g., aminoglycosides): increased risk of renal injury.

Moderate Interactions (Monitor Closely): - Antihypertensives: additive hypotensive effect. - Lithium: altered renal clearance may raise lithium levels. - Corticosteroids: may worsen fluid retention.
