VAPTAN 15MG TABLET 7'S
About VAPTAN 15MG TABLET 7'S
VAPTAN 15MG TABLET 7'S belongs to a group of medicines called vasopressin V2 receptor antagonist used to treat hyponatremia (low levels of sodium) in patients with heart failure, liver disease and hormonal imbalances such as Syndrome of Inappropriate Antidiuretic Hormone (SIADH). Additionally, VAPTAN 15MG TABLET 7'S is also used to treat autosomal dominant polycystic kidney disease (ADPKD).
VAPTAN 15MG TABLET 7'S contains ‘tolvaptan’ that works by blocking the effect of vasopressin, resulting in decreased water reabsorption, a net increase in free water excretion (aquaresis) and an increase in serum sodium concentrations. This decrease in free water is not associated with an increased excretion of sodium or potassium ions, the increase in serum sodium concentration is solely a result of increased urine production
You are advised to take VAPTAN 15MG TABLET 7'S for as long as your doctor has prescribed it for you depending on your medical condition. In some cases, you may experience certain common side-effects such as dizziness, headache, dry mouth, fatigue, diarrhoea, thirst and increased urge to urinate. Most of these side-effects do not require medical attention and will resolve gradually over time. However, you are advised to talk to your doctor if you experience these side-effects persistently.
Do not take VAPTAN 15MG TABLET 7'S if you are pregnant as it may cause foetal harm. Consult your doctor before taking VAPTAN 15MG TABLET 7'S if you are breastfeeding. VAPTAN 15MG TABLET 7'S is not recommended for children below 18 years as the efficacy and safety have not been established. VAPTAN 15MG TABLET 7'S may cause dizziness, so drive with caution. Avoid consuming alcohol as it might cause increased dizziness. Inform your doctor about all the medicines you are taking and about your health condition to rule out any unpleasant side-effects.

Medicinal Benefits
VAPTAN 15MG TABLET 7'S belongs to a group of medicines called vasopressin V2 receptor antagonist. VAPTAN 15MG TABLET 7'S is used to treat hyponatremia (low levels of sodium) in patients with heart failure, liver disease and hormonal imbalances such as Syndrome of Inappropriate Antidiuretic Hormone (SIADH). Besides this, VAPTAN 15MG TABLET 7'S is also used to treat autosomal dominant polycystic kidney disease (ADPKD). VAPTAN 15MG TABLET 7'S works by blocking the effect of vasopressin, a hormone which is involved in the formation of cysts in ADPKD patients. By blocking the effect of vasopressin, VAPTAN 15MG TABLET 7'S slows down the development of cysts in kidneys and reduces the symptoms of the disease. VAPTAN 15MG TABLET 7'S antagonises the effect of vasopressin, this results in an increase in free water clearance and decreases urine osmolality due to increased urinary excretion, thereby increases serum sodium concentrations.

Disease/Condition Glossary
Hyponatremia: Sodium is an important electrolyte that helps in maintaining water balance in and around the cells. It helps in proper nerve, muscle functioning and maintains stable blood pressure levels. Low levels of sodium in the blood are referred to as hyponatremia. Normal levels of sodium are 135-145 milliequivalance per litre. Hyponatremia occurs when the level is below 135mEq/L. Symptoms include weakness, tiredness, nausea, vomiting, headache, irritability, confusion and muscle spasms.
Autosomal Dominant Polycystic Kidney Disease (ADPKD): It is an inherited disorder in which cysts are developed in the kidney. These cysts are non-cancerous sacs that contain a water-like fluid which puts pressure on the surrounding tissues, leading to reduced kidney function. Symptoms include high blood pressure, swollen abdomen, and back or side pain.
