This results in decreased blood pressure and improved blood flow to vital organs.


According to the American Heart Association, Calan Sr is indicated for the treatment of hypertension, angina pectoris, and certain types of arrhythmias. It is commonly used as a first-line therapy for patients with essential hypertension or those with comorbid conditions such as diabetes or chronic kidney disease.

The drug was also found to be well-tolerated with a low incidence of adverse events, making it a favorable option for long-term treatment.

Patient Education and Counseling

Healthcare providers should educate patients about the importance of adherence to therapy, lifestyle modifications, and regular monitoring of blood pressure.
