Shiokem 15mg Tablet 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). Additionally, Shiokem 15mg Tablet is also used to treat autosomal dominant polycystic kidney disease (ADPKD).
 
Shiokem 15mg Tablet 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 Shiokem 15mg Tablet as long as your doctor has prescribed it for you, depending on your medical condition.

Shiokem 15mg Tablet belongs to a group of medicines called vasopressin V2 receptor antagonist. Shiokem 15mg Tablet 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, Shiokem 15mg Tablet is also used to treat autosomal dominant polycystic kidney disease (ADPKD). Shiokem 15mg Tablet 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, Shiokem 15mg Tablet slows down the development of cysts in kidneys and reduces the symptoms of the disease. Shiokem 15mg Tablet antagonises the effect of vasopressin; this results in an increase in free water clearance and decreases urine osmolality due to increased urinary excretion, thereby increasing serum sodium concentrations.
