Tolvaptan 30 mg

What is Tolvaptan 30 mg?

Tolvaptan 30 mg is a prescription medication containing the active ingredient Tolvaptan, produced by Glenmark Pharmaceuticals Ltd. It is primarily indicated for the treatment of the syndrome of inappropriate antidiuretic hormone secretion (SIADH), a condition characterized by excessive release of antidiuretic hormone leading to water retention and dilutional hyponatremia.

Used worldwide, including in Canada, Tolvaptan 30 mg (with a lower 15 mg strength also available) helps to restore sodium balance by promoting the excretion of free water while preserving essential electrolytes. This medication offers a targeted approach to managing SIADH symptoms under medical supervision.

Uses of Tolvaptan 30 mg

• Treatment of hyponatremia associated with SIADH
• Management of low blood sodium levels in conditions causing water retention
• Supporting fluid balance control in hospitalized patients with SIADH
• Adjunctive therapy for disorders involving inappropriate antidiuretic hormone activity

How Tolvaptan 30 mg Works

Tolvaptan 30 mg acts as a selective vasopressin V2 receptor antagonist. By blocking these receptors in the kidney's collecting ducts, it inhibits the action of antidiuretic hormone (ADH). This results in increased excretion of free water (aquaresis) without significant loss of electrolytes, especially sodium. Consequently, Tolvaptan helps correct hyponatremia by reducing fluid overload and restoring plasma sodium concentration to safer levels.

Benefits of Tolvaptan 30 mg

• Effectively corrects serum sodium levels in SIADH patients
• Reduces fluid retention without causing electrolyte imbalance
• Well-tolerated with a predictable mechanism of action
• Convenient oral dosage for ease of administration
• Manufactured to high-quality standards by Glenmark Pharmaceuticals Ltd.

Dosage and Administration

Tolvaptan 30 mg is typically administered orally once daily, with dosage adjusted according to clinical response and serum sodium levels. Treatment should begin under specialist supervision, informed by clinical review of SIADH management, with close monitoring of sodium and fluid balance during therapy. Patients are advised to follow their healthcare provider’s instructions carefully and not to alter the dose without consultation.

Who Should Use Tolvaptan 30 mg?

This medication is suitable for patients diagnosed with SIADH experiencing symptomatic hyponatremia or at risk of complications from fluid overload. It is intended for individuals who require medical intervention to manage inappropriate secretion of antidiuretic hormone and associated electrolyte disturbances.

Who Should Avoid Tolvaptan 30 mg?

Patients who have known hypersensitivity to Tolvaptan or any of its components should avoid this medication. It is contraindicated in individuals with hypovolemic hyponatremia or anuria.
