Propranolol
Propranolol, the active ingredient in Inderal, is a beta blocker used for high blood pressure, angina and migraine prevention. Inderal is the only propranolol product listed here, in four tablet strengths from 10 mg to 80 mg.
Key points
- A beta blocker in the Heart & Blood Pressure category that slows the heart rate and relaxes blood vessels, reducing the workload on the heart.
- Beyond Hypertension and Angina Pectoris, propranolol is also used for irregular heartbeats, essential tremor, and to improve survival after a heart attack.
- Stopping propranolol suddenly can cause serious heart problems, so the dose is reduced gradually rather than stopped at once.
How does Propranolol work?
Propranolol blocks the action of adrenaline on the heart and blood vessels. By stopping these signals, it slows the heart rate and widens the arteries, which lowers blood pressure and reduces the amount of oxygen the heart muscle needs.
Because propranolol is fat-soluble, it crosses into the brain. That is how it prevents migraine attacks and reduces essential tremor, though it may also cause tiredness or vivid dreams.
