Q

What is the mechanism by which beta receptor agonists mitigate an asthma attack?

20
Q

What is the primary therapeutic use for beta receptor antagonists?

A

Hypertension

21
Q

What are the common side effects of non-selective beta receptor antagonists?

A

Beta 2 blockade in bronchial smooth muscle, delayed recovery from insulin-induced hypoglycemia in diabetic patients.

22
Q

Amphetamine, cocaine, tyramine, and ephedrine belong to which class of adrenergic drugs?

A

Indirect-acting sympathomimetics

23
Q

What is the adrenergic mechanism of action of amphetamine?

A

Displaces norepinepherine from vesicles and increases release into the synapse through transporters

24
Q

What are the therapeutic uses of amphetamine?

A

Appetite suppression, narcolepsy, ADHD

25
Q

What is the adrenergic mechanism of action of cocaine?

A

Blocks monamine transmitter reuptake, increasing synaptic concentrations of norepinepherine

26
Q

What are the therapeutic uses of cocaine?

A

Ear, nose, and throat surgical procedures, limiting bleeding (intense vasoconstrictor effect), topical application

27
Q

What are the common side effects of cocaine?

A

Seizures, hypertensive crisis, cerebral hemorrhage, cardiac arrhythmias, myocardial ischemia

28
Q

What is the adrenergic mechanism of tyramine?

A

Causes release of catecholamines from vesicles, leading to increased synaptic concentrations of norepinepherine

29
Q

What is the primary contraindication for tyramine use?

A

Concurrent MAO inhibitor use

30
Q

What foods have high concentrations of tyramine?

A

Fermented food, some cheeses, pickled or marinated meats

31
Q

What is the adrenergic mechanism of ephedrine?

A

Mixed action: causes catecholamine release from vesicles and directly activates adrenergic receptors

32
Q

What are the therapeutic uses of ephedrine?

A

Asthma, decongestant (pseudoephedrine)
