antagonists
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
What are the toxic effects for alpha blocker and beta blockers?
bronchiolar
Congestive
diabetic
1. severe ___________ constriction
2. hypotension
3. __________ heart failure, A-V block
4. Hypoglycemia in __________ receiving treatments
1. asthma
2. Hypotension
3. Congestive heart failure, heart block

Caution: diabetes
What are the contraindications for alpha blocker and beta blockers (antagonists)?
contraindications for alpha blockers and beta blockers
1. asthma
2. Hypotension
3. Congestive heart failure, heart block
b blockers
What is the adrenergic blocking agent for the toxic effect, severe bronchiolar constriction?
alpha and beta blockers
What is the adrenergic blocking agent for the toxic effect, hypotension?
beta blockers
What is the adrenergic blocking agent for the toxic effect, congestive heart failure?
beta blockers
What is the adrenergic blocking agent for the toxic effect, hypoglycemia in diabetes receiving treatments?
