Why is Cardinal (Propranolol) prescribed?
Cardinal (Propranolol), a type of medication known as a beta blocker, is used in
the treatment of high blood pressure, angina pectoris (chest pain,
usually caused by lack of oxygen to the heart due to clogged arteries),
changes in heart rhythm, prevention of migraine headache, hereditary
tremors, hypertrophic subaortic stenosis (a condition related to exertional
angina), and tumors of the adrenal gland. It is also used to reduce
the risk of death from recurring heart attack.
When used for the treatment of high blood pressure, it is effective
alone or combined with other high blood pressure medications, particularly
thiazide-type diuretics. Beta blockers decrease the force and rate
of heart contractions, reducing the heart's demand for oxygen and lowering
blood pressure.
