1 What is Inderal?

Brand: Inderal

Generic: Propranolol

Inderal is a beta-blocker that slows down the heart rate. Propanolol works by causing changes to the nerve signals in the heart, slowing down very fast or irregular heart rate.

Doctors prescribe Propanolol to treat angina (chest pain), hypertension, arrhythmias (irregular heart rate rhythm) and prevent and treat heart attack.

Propanolol is a prescription drug. Because this brand of Propanolol is administered by injecting it into the veins, you can only have it at the hospital or doctor’s clinic.
