Tolvaptan

Drug Details

Tolvaptan is a medication used to treat low sodium levels in the blood, a condition known as hyponatremia. This can occur in situations like heart failure or certain hormonal imbalances. As a vasopressin receptor antagonist, Tolvaptan works by preventing the hormone vasopressin from binding to receptors in the kidneys. This process reduces water reabsorption, leading to increased urine production and a gradual increase in blood sodium levels. It is important to note that different brands of Tolvaptan may be used for different purposes, so always follow your healthcare provider's instructions regarding brand usage. Common side effects include thirst, dry mouth, and frequent urination. When starting this medication, monitoring in a healthcare setting is necessary to ensure sodium levels rise at a safe rate. Always consult with your healthcare provider before taking any medication.
