Propranolol is the generic name for the medication commonly known by the brand name Inderal [1][2].
Why is Inderal prescribed?
Inderal, containing the active ingredient propranolol, is a beta-blocker medication used to treat a variety of conditions. These include high blood pressure (hypertension), chest pain (angina), heart rhythm disorders (arrhythmias), and to prevent migraine headaches [1][2]. It is also prescribed to help reduce the risk of death after a heart attack [1].
How does propranolol work?
Propranolol works by blocking the effects of adrenaline (epinephrine) on the body's beta receptors. This action slows the heart rate, reduces the force of heart contractions, and lowers blood pressure. By reducing the heart's workload and improving blood flow, it can alleviate symptoms associated with various cardiovascular and neurological conditions [1][2].
Are there different forms of propranolol?
Yes, propranolol is available in several formulations, including immediate-release and extended-release tablets, as well as an oral solution [2]. These different forms allow for varying dosing schedules and absorption rates to suit different patient needs.
Who makes generic propranolol?
Multiple pharmaceutical companies manufacture generic versions of propranolol. These generics are bioequivalent to the branded Inderal, meaning they have the same active ingredient, dosage form, strength, and route of administration, and are intended to have the same clinical effect [3].
When did propranolol go off-patent?
The original patents for Inderal have long expired. This has allowed for the widespread availability of generic propranolol since the late 1980s and early 1990s [4].
What are the side effects of propranolol?
Common side effects associated with propranolol can include dizziness, tiredness, slow heartbeat, nausea, diarrhea, and cold hands and feet [1][2]. More serious side effects can occur and may require medical attention.
Can propranolol be used for anxiety?
While not its primary approved indication, propranolol is sometimes prescribed off-label to help manage the physical symptoms of anxiety, such as rapid heartbeat, trembling, and sweating. This is due to its ability to block the effects of adrenaline [1][2].
What is the difference between propranolol and other beta-blockers?
Propranolol is a non-selective beta-blocker, meaning it affects both beta-1 and beta-2 receptors in the body. Some other beta-blockers are selective for beta-1 receptors, which may lead to different side effect profiles or suitability for certain patients [5].
