What is Tolvaptan 30 mg?
Tolvaptan 30 mg is a prescription medication manufactured by Glenmark Pharmaceuticals Ltd. It is specifically formulated to treat the Syndrome of Inappropriate Antidiuretic Hormone Secretion (SIADH), a condition characterized by excessive release of antidiuretic hormone (ADH) leading to water retention and low blood sodium levels. This medication helps restore the balance of fluids in the body by promoting the excretion of excess water.
As a selective vasopressin V2-receptor antagonist, Tolvaptan 30 mg works by blocking the effect of ADH in the kidneys, which aids in increasing urine output without causing significant loss of electrolytes. This property makes it a valuable treatment for patients experiencing hyponatremia caused by SIADH.
Developed under stringent quality standards, Tolvaptan 30 mg is trusted by healthcare professionals for its efficacy and safety profile. It is available for patients in Malaysia who require advanced therapeutic options for managing disorders related to abnormal water retention.
Uses of Tolvaptan 30 mg
- Treatment of Syndrome of Inappropriate Antidiuretic Hormone Secretion (SIADH)
- Management of hyponatremia associated with SIADH
- Regulation of water balance in patients with excessive ADH secretion
How Tolvaptan 30 mg Works
Tolvaptan 30 mg functions as a vasopressin V2-receptor antagonist which binds selectively to these receptors in the kidneys. Normally, vasopressin or antidiuretic hormone promotes water reabsorption in the renal collecting ducts. By blocking this action, Tolvaptan facilitates increased free water excretion through urine. This process helps correct low sodium levels by reducing water retention without significant sodium loss, effectively restoring proper fluid and electrolyte balance.
How to take Tolvaptan 30 mg
Tolvaptan 30 mg should be taken exactly as prescribed by your healthcare provider. It is generally administered orally once daily, with or without food. Patients should start with a low dose which may be adjusted depending on response and tolerance. It is important to drink adequate fluids unless otherwise directed by your doctor. Regular monitoring of blood sodium levels and kidney function is recommended during treatment to ensure safety and effectiveness.
