What Is Propranolol 20mg?
Propranolol is a non-selective beta-blocker that works by slowing the heart rate and reducing the force of the heart's contractions. This lowers blood pressure and reduces the heart's workload. Propranolol is FDA-approved for several conditions, including hypertension, angina, certain heart rhythm problems, migraine prevention, and essential tremor. It is available as a 20mg tablet under the brand name Inderal and as a generic.
