Alpha-1 adrenergic receptor stimulation causes: - Answer- vasoconstriction and an
increased blood pressure
Alpha-1 adrenergic receptor blockade results in: - Answer- vasodilation and reduced
blood pressure
The only alpha-1 adrenergic receptor blocking drugs used to treat hypertension include:
- Answer- prazosin and alfuzin
What can occur with the first dose of an alpha-1 receptor blocking agent? - AnswerOrthostatic hypotension
Beta adrenergic blocking agents: - Answer- propranolol, metoprolol, esmolol (shortacting), atenolol, nadolol
Beta-1 adrenergic stimulation results in: - Answer- increased heart rate, increased blood
pressure and increased cardiac output
Beta-1 adrenergic blockade results in: - Answer- reduced heart rate, reduced blood
pressure and reduced cardiac output
Beta blocking agents include: - Answer- nonselective agents (e.g., propranolol) that
block beta-2 receptors in the lungs
Selective beta blockers block: - Answer- beta-1 receptors in the heart and vasculature
What is not used in hypertensive emergencies and why? - Answer- Carvedilol- because
it is an alpha and beta receptor blocker
First-line therapy for hypertension include: - Answer- ACE inhibitors, angiotensin
receptor blockers (ARBs), and calcium channel blockers
Beta-blockers are not considered first-line therapy in hypertension because of: -
Answer- increased morbidity and mortality
Dihydropyridine (DHP) calcium channel blockers: - Answer- amlodipine, nicardipine,
isradipine, felodipine, nifedipine
Non-DHP calcium channel blockers: - Answer- diltiazem, verapamil
