What is Tolvaptan 15 mg (TOLVAPTORIS 15)?

Tolvaptan 15 mg (known by the brand name TOLVAPTORIS 15) is a medication commonly prescribed to treat autosomal dominant polycystic kidney disease (ADPKD) and manage fluid retention in heart failure. Available as a tablet containing 15 mg of Tolvaptan, this medication is known for its ability to improve kidney function and control excess fluid in the body.

By targeting the underlying causes of kidney cyst growth and fluid retention, Tolvaptan 15 mg plays a pivotal role in improving the quality of life for many patients.

Tolvaptan 15 mg Uses

Tolvaptan tablets 15 mg are primarily used in the following conditions:

  1. Autosomal Dominant Polycystic Kidney Disease (ADPKD): Tolvaptan 15 mg slows the progression of kidney cyst development, which can otherwise lead to kidney failure. It helps preserve kidney function and may reduce the risk of complications.

  2. Heart Failure: In heart failure patients, Tolvaptan 15 mg is used to manage fluid retention (edema). It helps alleviate symptoms such as swelling in the legs, ankles, or abdomen, and shortness of breath due to fluid buildup in the lungs.

  3. Hyponatremia: In some cases, Tolvaptan may be used to correct low sodium levels (hyponatremia), a potentially life-threatening condition.

How Does Tolvaptan 15 mg Work? (Tolvaptan Mechanism of Action)

The mechanism of action of Tolvaptan 15 mg involves its ability to block the effects of vasopressin, a hormone that typically causes the kidneys to retain water. By inhibiting vasopressin, Tolvaptan increases the amount of water the kidneys excrete, reducing fluid retention and slowing the growth of cysts in the kidneys. This is especially helpful in managing ADPKD and heart failure.

  • In ADPKD, Tolvaptan 15 mg helps to reduce the rate at which cysts form and grow in the kidneys, which can delay kidney function decline.

  • In heart failure, Tolvaptan helps to manage the excess fluid that accumulates in the body, improving symptoms like swelling and breathlessness.

Tolvaptan Dose

The Tolvaptan dose depends on the condition being treated and the individual patient's needs. Tab Tolvaptan 15 mg is usually the starting dose for ADPKD or heart failure treatment, but the dose can increase based on your doctor's recommendation.

  • For ADPKD: Treatment often begins with a 60 mg per day dose, divided into two doses, which may be increased to 90 mg or 120 mg per day, depending on the response and tolerance.

  • For Heart Failure: The dose is carefully adjusted to manage fluid levels effectively. Your doctor will monitor fluid retention and adjust your Tolvaptan dose as needed.

Tolvaptan Tablets 15 mg: How to Take Them

  • Tolvaptan tablets 15 mg should be taken by mouth, typically once daily at the same time each day.

  • Tolvaptan 15 mg tablets should be taken with or without food.

  • It's important to follow the prescribed dosage and not take more than recommended to avoid serious complications like dehydration and electrolyte imbalance.
