Inderal was originally sold by Wyeth Pharmaceuticals. However, now that the patent has expired, a number of companies manufacture a generic Inderal. Sold as Propranolol tablets, the drug is used to treat several conditions related to the heart and blood vessels, such as high blood pressure and angina. Generic Inderal is available in several strengths, from 10 to 80 mg.
Generic Inderal: An OverviewInderal® (propranolol hydrochloride) is a prescription medication that is used for lowering blood pressure (hypertension), the relief of angina symptoms, migraine prevention, the control of atrial fibrillation, and improving the chances of survival after a heart attack. Inderal may also be used for other reasons, such as to treat people with hypertrophic subaortic stenosis, an essential tremor, or pheochromocytoma.
Inderal is part of a class of medicines called beta-adrenergic blocking agents, or beta blockers for short. As the name suggests, Inderal helps to block beta receptors, which are receptors in the body that bind stress hormones, such as adrenaline (epinephrine). These receptors are found in many places throughout the body, including the heart and blood vessels. By blocking beta receptors, Inderal causes the reverse effect of the stress hormones. It decreases heart rate and both systolic and diastolic blood pressure, as well as the workload of the heart, meaning that the heart requires less blood and oxygen to work properly.
Inderal was originally manufactured by Wyeth Pharmaceuticals. It has since come off-patent, making it available as a generic. In fact, brand-name Inderal is no longer being manufactured (as is common with older medications with expired patents).
