Uses of Alprenolol
This drug can cause selective β1-adrenoceptor blockade as it functions as a partial agonist. The pharmacology of this drug is similar to Atenolol. It is taken orally for the treatment of angina. It is the chest pain caused by reduced oxygen supply and waste removal due to lack of blood. It is also used for treating hypertension, arrhythmia, ventricular tachycardias and atrial fibrillation.
Pharmacology of Alprenolol
Alprenolol impairs the conduction of AV node and decreases the rate of sinus. It may also be capable of increasing plasma triglyceride as well as decreasing the levels of HDL-cholesterol. This non-polar hydrophobic drug has moderate lipid solubility. Alprenolol has very low intrinsic sympathomimetic activity as well as little direct myocardial depressant activity.

This drug may cause various adverse reactions in humans such as:
- Heart block
- Heart failure
- Skin rash
- Pulmonary and retroperitoneal fibrosis
- Reversible alopoecia
- Lupus-like syndrome
