Zestoretic Tab 20mg is a prescription medication used primarily to treat high blood pressure (hypertension) and to manage chronic heart failure. It combines two active ingredients that work by relaxing blood vessels, making it easier for the heart to pump blood, while also helping reduce fluid retention and lower blood pressure. This combination therapy provides effective control of blood pressure and can also lessen symptoms associated with heart failure. With this medication, regular monitoring of blood pressure and kidney function is essential for effective management and treatment.
