also called ___________, blocking or inhibiting agents or sympatholytic drugs

antagonists

Drugs INHIBITING adrenergic effects
|
|
alpha blocking agents (therapeutic uses)
|
1. Locally - prevent local necrosis following NE overdose
2. Pheochromocytoma (tumor of adrenal gland) -diagnosis - see if this is cause of hypertension -preoperative treatment - used to gradually remove stimulation (otherwise a drastic decrease in BP will occur when tumor removed. 4. Treat hypertension Which adrenergic inhiting drug is it? |
|
(alpha blocking agents)
necrosis adrenal hypertension |
1. Locally - prevent local ________ following NE overdose
2. Pheochromocytoma (tumor of _______ gland) -diagnosis - see if this is cause of hypertension -preoperative treatment - used to gradually remove stimulation (otherwise a drastic decrease in BP will occur when tumor removed. 4. Treat hypertension |

Pheochromocytoma
|
tumor of adrenal gland
|
|
Pheochromocytoma
(alpha blocking agents) |
-preoperative treatment - used to gradually remove stimulation (otherwise a drastic decrease in BP will occur when tumor removed.
|
|
Therapeutic uses - Beta blocking agents
|
1. Cardiac arrhythmias
-suppress ectopic pacemakers -especially good at slowing ventricles and correcting digitalis induced arrhythmias 2. Prevention of anginal pain (decreases cardiac work) 3. Hypertension 4. Controlling signs of thyrotoxicosis -counteracts tachycardia, high BP, increased metabolism, increased body temp., and tremulousness 5. Prophylaxis of migraine headaches and, perhaps, treatment of acute attacks (mechanism unknown -- perhaps blocks vasodilation). |

arrhythmias
anginal thyrotoxicosis tachycardia |
1. Cardiac __________
-suppress ectopic pacemakers -especially good at slowing ventricles and correcting digitalis induced arrhythmias 2. Prevention of ________ pain (decreases cardiac work) 3. Hypertension 4. Controlling signs of ______________-counteracts __________, high BP, increased metabolism, increased body temp., and tremulousness 5. Prophylaxis of migraine headaches and, perhaps, treatment of acute attacks (mechanism unknown -- perhaps blocks vasodilation). |
|
1. asthmatic wheezing (b blocker)
2. Dizziness (alpha blocker) 3. Tiredness and depression (both alpha and beta blocker as well as CNS effect) 4. Nausea and diarrhea (chiefly B blocker that stops inhibition of gastrointestinal walls but also alpha blocker that stops sphincter contraction -- both allow parasympathetic stimulation to be unbalanced.) |
What are the side effects of alpha and beta blockers and of reduced NE release (like that caused by reserpine)
|
|
asthmatic
depression sphincter |
1. ________ wheezing (b blocker)
2. Dizziness (alpha blocker) 3. Tiredness and _________(both alpha and beta blocker as well as CNS effect) 4. Nausea and diarrhea (chiefly B blocker that stops inhibition of gastrointestinal walls but also alpha blocker that stops ___________ contraction -- both allow parasympathetic stimulation to be unbalanced.) |
|
b blocker
|
What adrenergic agent causes the side effect, asthmatic wheezing?
|
|
alpha blocker
|
What adrenergic agent causes the side effect, dizziness?
|
|
both alpha and beta blocker as well as CNS effect
|
What adrenergic agent causes the side effect, tiredness and depression?
|
|
chiefly B blocker that stops inhibition of gastrointestinal walls but also alpha blocker that stops sphincter contraction -- both allow parasympathetic stimulation to be unbalanced.
|
What adrenergic agent causes the side effect, Nausea and diarrhea?
|
|
1. severe bronchiolar constriction
2. hypotension 3. Congestive heart failure, A-V block 4. Hypoglycemia in diabetic receiving treatments |
