🧬 About Natrise (Tolvaptan)
Natrise 15 mg is a prescription-grade Tolvaptan formulation developed by Sun Pharma, one of India’s leading pharmaceutical manufacturers.
Tolvaptan is a selective vasopressin V2 receptor antagonist that helps correct hyponatremia (low blood sodium) in patients with heart failure or syndrome of inappropriate antidiuretic hormone secretion (SIADH).
It is also used in the management of autosomal dominant polycystic kidney disease (ADPKD) to slow down cyst growth and preserve kidney function.
⚗️ Mechanism of Action
Tolvaptan blocks the binding of vasopressin (antidiuretic hormone) to V2 receptors in the renal collecting ducts, reducing water reabsorption without affecting sodium or potassium excretion.
This aquaresis process raises serum sodium levels and lowers fluid overload, helping patients with congestive heart failure or liver cirrhosis.
In ADPKD, Tolvaptan helps limit cystic fluid accumulation and renal volume expansion.
💊 Dosage & Administration
| Indication | Typical Dose | Frequency | Notes |

| Hyponatremia (SIADH / CHF) | 15 mg once daily | May increase to 30 mg based on response | Monitor serum sodium & hydration |
| ADPKD (Polycystic Kidney Disease) | Starting 45 mg AM / 15 mg PM (up to 90 mg daily) | Under medical supervision | Requires liver function monitoring |
