part 2 Flashcards
alpha-adrenergic blockers
phentolamine mesylate doxazosin mesylate prazosin Hcl terazosin HCl carvedilol (alpha 1, beta1 and beta2) labetalol *alpha 1 beta1 and beta2)
drugs that act on beta2 receptor
albuterol
metaproterenol sulfate (alupent)
terbutaline sulfate
to treat bronchospasm by bronchodilation
phentolamine mesylate (Regitine)
alpha 1 adrenergic blockers
phentolamine mesylate (Regitine)
alpha 1 adrenergic blockers
alpha blockers promote ______ causing a decrease in _____
alpha blockers promote vasodilation, causing a decrease in blood pressure
nonselective beta blcokers should be used in extreme caution with any patient who has
chronic obstructive pulmonary disease (COPD) or asthma
as a result of beta1 blocking
heart rate decreases, bronchoconstriction occurs
alpha1 adrenergic blocker response:
vasodilation; decreases blood pressure; reflex tachycardia; miosis (constriction of pupil); suppresses ejaculation; reduces contraction of smooth muscle in bladder neck and prostate land
beta1 adrenergic blocker
decreases heart rate; reduces force of contraction
beta2 adrenergic blocker
constricts bronchioles; contracts uterus; inhibits glycogenolysis, which can decrease blood sugar
