|
Definition
|
|
Term
| binds to a receptor and causes a response |
|

|
|
Term
| antagonist are also called |
|
Definition
| sympatholytics because they lyse or inhibit. |
|
|
Term
| a1 adrenegic receptors are locating on the |
|
Definition
| muscle or tissue, or organ that the nerve is stimulatoin |
|
|
Term

|
|
Term
| wen a blockers inhibit stimulation o fthe sns at the a adrenergic receptor what happens? |
|
Definition
| leads to vasodilation, decreased blood pressure, miosis or pupil constriction. |
|
|
Term
| a blockers cause both areterial and venous dilation which reduces periheral vascular resistance and bp therefore they are used to treat. |
|
Definition
|
|
Term
___ blockers are given to decrease resistance in blood flow in arteries and veins why? |
|
Definition
to reduce obstructions and give relief ie headaches, they vasoconstric dilated arterioles. ie: dilatin reduces peripheral vascular resistance and bp. |
|
|
Term
possible adverse affects of a blockers |
|
Definition
drug allergy peripheral vascular disease hepatic and renal disease coronary artery disease peptic ulcer and sepsis |
|
|
Term
| Toxity and removal of a blockers |
|
Definition
stomach emptying by vomit or gastric lavage. activated charcoal along with suportive measures bp watch fluids vasopressor drugs |
|
|
Term
| b blockers are also called |
|
Definition
| cardioselective b blockers |
|
|
Term
| _______ competes with and blocks noe and epinephrine at b adrenergic receptors, b receptor sites can no longer be stimulated by NT and sns stimulation is blocked. |
|
Definition
|
|
Term
| b1 blockersblock the b1 adrenergic receptors on the surgace of the heart which reduces? |
|
Definition
| myocardial stimulation which in tun reduces the heart rate and slows conduction through the av node, sa node and decreases myocardial O2 demand by decreasing heart contraction force. |
|
|
Term
| non selective b blockersblock b2 adrenergic receptors on the |
|
Definition
| smooth muscle of the bronchioles and blood vessels. |
|
|
Term
| b blockers that are selective for b adrenergic receptors |
|
Definition
| cardioselective b blockers or b1 blockers |
|
|
Term
| nonselective b blockers block |
|
Definition
|
|
Term
| ____ blockers leads to vasodilation, decreased bp, miosis, pupil dilation and decreased ejactulation |
|
Definition
|
|
Term
|
Definition
vasodilation (migrane relief) Dilation (to decrease bp and arteriole pressure) |
|
|
Term
| __ blockers compete for protein sites with _____ and ___ and are nonselective. |
|
Definition
|
|
Term
| __ blockers blocks b1 and b2 located in the smooth muscle, bronchioles, vessles. |
|
Definition
|
|
Term
| because b blockers compete for b receptor sites with epi and noe. b adrenergic rec. sites can no longer be stimulated so? |
|
Definition
| NT and sns stimulation is blocked |
|
|
Term
| cardioselective b blockers block the |
|
Definition
| b1 adrenergic rec. on the surface of the heart, which reduces myocardial stimulation, which in turn reduces heart rate. |
|
|
Term
| b blockers are considered |
|
Definition
|
|
Term
| beta blocker effects on the heart make them good drugs for treatment of |
|
Definition
| dysrhythias (irregular heart rhythms) |
