Study Notes
Mechanism of Action
- Beta blockers primarily work by blocking beta-adrenergic receptors, leading to reduced heart rate and myocardial contractility.
Medications
- Timolol is a beta blocker utilized for treating intraocular pressure and is administered topically in the eye.
Alpha Blockers
- The main purpose of alpha blockers is to relax smooth muscle in blood vessels, which helps to lower blood pressure and improve blood flow.
Propranolol
- Propranolol is primarily used for managing hypertension, arrhythmias, anxiety, and migraine prophylaxis.
Benign Prostatic Hyperplasia (BPH)
- Tamsulosin is the most common medication prescribed for alleviating symptoms of benign prostatic hyperplasia.
Nonselective Adrenergic Blockers
- Prior to administering nonselective adrenergic blockers, blood pressure and heart rate should be monitored closely to avoid adverse effects.
Medication Classification
- Beta blockers reduce heart rate through beta1 receptor blockade, impacting cardiac function directly.
Purposes of Alpha Blockers
- Alpha blockers are utilized for treating hypertension, urinary retention in BPH, and for certain conditions involving increased sympathetic nervous system activity.
Vasodilation
- Prazosin is a medication well-known for its vasodilating properties, leading to lowered blood pressure.
Drug Endings
- Beta blockers commonly end in -olol.
- Alpha blockers typically end in -azosin.
