Manitol Hztm (Mannitol)

Mannitol, the active ingredient in Manitol Hztm, is an osmotic diuretic presented as a sterile intravenous solution for intravenous use. It creates an osmotic gradient that promotes water excretion and helps lower intracranial and intra‑ocular pressure in acute clinical settings.

GNH India supplies Manitol Hztm as a licensed, GDP‑compliant international pharmaceutical supplier serving hospitals, transplant centres, oncology centres, pharmacies and clinics worldwide.

Indications & Clinical Uses

Mannitol is employed in several clinical situations where rapid osmotic diuresis or pressure reduction is required.

  • Intracranial hypertension: reduces cerebral edema and intracranial pressure.
  • Acute glaucoma: lowers intra‑ocular pressure to preserve vision.
  • Renal failure with oliguria: increases urine output to aid renal clearance.
  • Drug intoxication: facilitates elimination of nephrotoxic substances through osmotic diuresis.

How It Works

  • Mannitol acts as an osmotically active agent that is filtered by the glomeruli but poorly reabsorbed in the renal tubules, creating an osmotic gradient that draws water into the tubular lumen. This increases urinary output and reduces fluid volume in the brain and eye, thereby lowering intracranial and intra‑ocular pressures.

Side Effects

Mannitol may cause a range of adverse reactions, from mild to severe, depending on patient factors and dosing.

Common Side Effects

  • Headache: mild to moderate pain often related to rapid fluid shifts.
  • Nausea and vomiting: gastrointestinal upset common with intravenous administration.
  • Electrolyte disturbances: especially hyponatremia or hypernatremia.
  • Transient hypotension: due to intravascular volume changes.
  • Flank pain: related to increased renal flow.

Serious or Rare Side Effects

  • Acute renal failure: risk in patients with pre‑existing kidney disease.
  • Pulmonary edema: fluid overload in susceptible individuals.
  • Severe electrolyte imbalance: can lead to cardiac arrhythmias.
  • Allergic reactions: including rash, itching, or anaphylaxis.
  • Hyperosmolar state: may cause neurological symptoms.
  • Hemolysis: rare but reported in high‑dose scenarios.

Precautions & Warnings

Mannitol requires careful monitoring and specific precautions to ensure safe use.

  • Renal function assessment: evaluate baseline creatinine and urine output before initiation.
  • Fluid balance monitoring: track input and output to avoid overload.
  • Electrolyte surveillance: check serum sodium, potassium, and osmolality regularly.
  • Cardiovascular status: monitor blood pressure and heart rate for hypotension.
  • Contraindications review: avoid in patients with active intracranial bleeding or severe pulmonary edema.
  • Store at 2-8°C: keep refrigerated, protect from light, do not freeze or shake.

Avoid Interactions

Mannitol can interact with several medications, altering its efficacy or safety profile.

Major Interactions (Avoid)

  • Loop diuretics (e.g., furosemide): may exacerbate electrolyte loss and renal impairment.
  • Nephrotoxic agents (e.g., aminoglycosides, amphotericin B): increase risk of acute kidney injury.
  • Other osmotic agents (e.g., glycerol, hypertonic saline): can cause severe hyperosmolar states.

Moderate Interactions (Monitor Closely)

  • Antihypertensives: additive blood‑pressure‑lowering effect may require dose adjustment.
  • Insulin or oral hypoglycemics: osmotic shifts can affect glucose control.
  • Lithium: altered renal clearance may increase lithium toxicity risk.

Frequently Asked Questions

Manitol Hztm is an intravenous osmotic diuretic used to lower elevated intracranial pressure, reduce intra‑ocular pressure in acute glaucoma, and promote diuresis in patients with renal failure or certain drug intoxications. It works by drawing water into the renal tubules and extracellular spaces, helping to manage fluid overload and pressure‑related complications.

Mannitol is filtered by the kidneys but not reabsorbed, creating an osmotic gradient that pulls water into the tubular lumen. This increases urine output and reduces fluid volume in the brain and eye. The resulting osmotic shift also helps to lower intracranial and intra‑ocular pressures, providing therapeutic benefit in emergencies.

The specific dose of Manitol Hztm is determined by the prescribing clinician based on the patient’s condition, weight, renal function, and therapeutic goals. Dosage regimens vary widely, and the prescriber will calculate the appropriate infusion rate and total amount required for each individual case.

Safety data for Mannitol in pregnancy and lactation are limited. It should only be used if the potential benefit justifies any potential risk to the fetus or infant. Healthcare providers will assess the risk‑benefit ratio before prescribing, and breastfeeding mothers should discuss possible exposure with their physician.

To order Manitol Hztm, submit an enquiry on the product page at gnhindia.com, specifying the required quantity. GNH India works with hospitals, pharmacies, and procurement teams worldwide, and will request trade or institutional credentials. After verification, the team provides pricing, availability, shipping details (including cold‑chain if needed), and import documentation.

Mannitol is a widely used osmotic diuretic with a rapid onset of action when given intravenously. Compared with other agents such as hypertonic saline, Mannitol provides both diuretic and pressure‑reducing effects, making it suitable for cerebral edema and acute glaucoma. Choice of agent depends on the clinical scenario, patient tolerance, and physician preference.

Manitol Hztm should be stored at 2‑8 °C in a refrigerator, protected from light. The solution must not be frozen or shaken. Before administration, inspect the vial for particulate matter or discoloration and use aseptic technique to maintain sterility.

Manitol Hztm is administered intravenously, typically as a slow infusion over several minutes to hours, depending on the indication. The infusion rate and total dose are set by the prescribing clinician, and vital signs should be monitored throughout the administration.

Serious risks include acute renal failure, especially in patients with pre‑existing kidney disease, severe electrolyte imbalances that can cause cardiac arrhythmias, pulmonary edema from fluid overload, and rare allergic reactions such as anaphylaxis. Continuous monitoring of renal function, electrolytes, and fluid status is essential.

Mannitol Hztm is contraindicated in patients with active intracranial bleeding, severe pulmonary edema, anuria, or known hypersensitivity to Mannitol. Caution is also advised for individuals with severe renal impairment, uncontrolled electrolyte disturbances, or those receiving other osmotic agents.
