Alprenolol
Alprenolol
Alprenolol (pronounced al-pre-no-lol), also known as alfaprolol or aptin, is a non-selective beta blocker used in the treatment of hypertension, angina pectoris, and myocardial infarction. It is not commonly used in the United States due to the availability of more effective and safer treatments.
Etymology
The term "Alprenolol" is derived from the chemical name alpha-(1-naphthyl)-beta-alcohol, indicating its chemical structure. The suffix "-olol" is common in beta blockers, indicating its class of medication.
Pharmacology
Alprenolol works by blocking the action of epinephrine and norepinephrine, hormones that stimulate the heart and blood vessels. By blocking these hormones, alprenolol reduces heart rate, blood pressure, and strain on the heart.
Side Effects
Common side effects of alprenolol include fatigue, dizziness, and shortness of breath. Less common side effects can include bradycardia, hypotension, and heart failure.
