Question

1. Propranolol hydrochloride (Inderal) is a beta-adrenergic blocker. It is often used as an antianginal, antiarrhythmic, and antihypertensive drug. Deloris Van Cartier’s mob boyfriend, Vince LaRocca, is taking Inderal.
Part 1: If Vince is taking Inderal, what is one possible disease or condition that would warrant taking this drug?
Part 2: Sister Mary Lazarus is a very stern woman who has high blood pressure. Do you think Inderal could help Sister May Lazarus? If so, explain HOW this beta-adrenergic blocker could help her condition (BE VERY SPECIFIC, noting structures that contribute to her disease state and HOW the drug would reverse the disease).
Part 3: Sister Mary Robert, a quiet and shy nun, accidently takes some Inderal. If the patient has low blood pressure, how could Inderal be dangerous to Sister Mary Robert?

Explanation / Answer

Part 1: This drug affects the heart and circulation (blood flow through arteries and veins). It is used to treat tremors, chest pain and hypertension. Vince might be suffering from a severe chest (angina), which would warrant to take this drug.

Part 2: Inderal is known to relax the cardiac muscle and to constrict the smooth muscle. It decreases the blood pressure or decreases cardiac contractility.

Part 3: Inderal is known for reducing the blood pressure and person having a low blood pressure would be in danger of a further reduction in the heart contractility. This would make the person go in coma due to lack of pumping of the blood from the heart.
