Tolvaptan 15 mg (Generic)

What is Tolvaptan 15 mg?

Tolvaptan 15 mg is a prescription medication containing the active ingredient Tolvaptan, developed and manufactured by Glenmark Pharmaceuticals Ltd. It is specifically designed to manage conditions related to the imbalance of water in the body caused by the Syndrome of inappropriate antidiuretic hormone secretion (SIADH). This condition leads to excessive water retention and low sodium levels in the blood, which Tolvaptan helps to correct.

In Malaysia, Tolvaptan 15 mg is widely used under medical supervision to restore normal sodium balance by promoting the excretion of free water without losing electrolytes, thus correcting hyponatremia. It belongs to a class of drugs known as vasopressin receptor antagonists, which work by blocking the effects of antidiuretic hormone (ADH) on the kidneys.

Because of its unique mechanism and targeted action, Tolvaptan 15 mg offers an effective solution for patients suffering from SIADH. It should always be used following a healthcare provider's prescription, ensuring proper evaluation and monitoring for safety and effectiveness.

Uses of Tolvaptan 15 mg

• Treatment of hyponatremia associated with SIADH
• Management of water retention disorders caused by excessive ADH secretion
• Correction of low sodium levels in patients with heart failure or liver cirrhosis (off-label, under medical advice)

How Tolvaptan 15 mg Works

Tolvaptan 15 mg acts as a selective vasopressin V2 receptor antagonist. Vasopressin, also known as antidiuretic hormone (ADH), normally signals the kidneys to retain water. In conditions like SIADH, excessive vasopressin results in too much water retention, diluting sodium levels in the blood.

Tolvaptan blocks the V2 receptors in the kidney's collecting ducts, reducing water reabsorption and increasing free water excretion via urine, known as aquaresis. This action raises blood sodium concentration safely without causing significant loss of electrolytes such as potassium or chloride.

By restoring sodium balance, Tolvaptan 15 mg alleviates symptoms related to water overload and low sodium levels, such as lethargy, confusion, and swelling.

How to take Tolvaptan 15 mg

Tolvaptan 15 mg should be taken exactly as prescribed by your healthcare provider. Typically, it is administered orally once daily with or without food. Always swallow the tablet whole with a sufficient amount of water.

It is crucial to follow dosing instructions carefully and not to discontinue treatment without medical consultation. Regular monitoring of blood sodium levels is necessary to adjust dosage and ensure safety.

Avoid drinking excessive fluids unless advised by your doctor during treatment to prevent dilution of sodium levels.
