Description
Introduction Of Tolvat 15mg Tablet:
Tolvat 15mg Tablet is a vasopressin receptor antagonist used to treat hyponatremia (low sodium levels) in patients with heart failure, liver disease, or hormonal imbalances, and to treat autosomal dominant polycystic kidney disease (ADPKD).
Tolvat 15mg Tablet can be taken with or without food, at the same time every day, to get the most benefit. Your doctor will decide what dose is necessary and how long you need to take it, depending on your medical condition. You should take it exactly as your doctor has advised. This medicine works by increasing urine production, so it is important not to restrict your fluid intake unless your doctor advises otherwise, and to drink water when thirsty to avoid dehydration. Your doctor may need to start this treatment in a hospital setting to monitor your sodium levels closely, especially at the start of treatment.
Increased thirst and increased urge to urinate are among the most common effects of this medicine. Your doctor may advise regular blood tests to monitor your liver function and sodium levels while you are on treatment. Inform your doctor immediately if you notice nausea, vomiting, fever, loss of appetite, dark urine, or yellowing of the skin or eyes, as this medicine can rarely affect liver function.
Uses Of Tolvat 15mg Tablet:
- Hyponatremia (low sodium levels)
- Autosomal dominant polycystic kidney disease (ADPKD)
Benefits Of Tolvat 15mg Tablet:
1. Hyponatremia
Hyponatremia is a condition of low sodium levels in the blood, often occurring in patients with heart failure, liver disease, or certain hormonal imbalances such as SIADH. Tolvat 15mg Tablet works by blocking the effect of vasopressin, increasing the amount of water released from the body through urine, which helps raise serum sodium concentrations back to a healthy level.
2. Autosomal dominant polycystic kidney disease (ADPKD)
ADPKD is a genetic disorder in which fluid-filled cysts develop in the kidneys, gradually affecting kidney function. Tolvat 15mg Tablet blocks the effect of vasopressin, a hormone involved in cyst formation, thereby slowing down the development of new cysts and reducing the symptoms of the disease.
Side effects of Tolvat 15mg Tablet:
Most side effects do not require any medical attention and disappear as your body adjusts to the medicine. Consult your doctor if they persist or if you’re worried about them.

Mechanism Of Action Of Tolvat 15mg Tablet:
Tolvat Tablet contains Tolvaptan, a vasopressin V2 receptor antagonist. It works by blocking the effect of vasopressin (an antidiuretic hormone) on the kidneys, resulting in decreased water reabsorption and a net increase in free water excretion (aquaresis). This leads to an increase in serum sodium concentrations without significantly affecting sodium or potassium excretion.
