sympathomimetics

Question 1

anorexiant
catecholamine

mydriatic

alpha or beta 1 adrenoceptor antagonist
Sympathomimetic
Reuptake inhibitor

Answer 1

reducer of appetite

dihydroxyphenyethylamine derivative a relatively polar molecule readily metabolized by cathechol-O-methyltransferase

Question 2

decongestant

Answer 2

alpha agonist drugs that reduces conjuctival, nasal, or oropharyngeal mucosal vasodilation by constricting blood vessels in the submucosal tissue

Question 3

mydriatic

Answer 3

dilation of the pupil,opp of miotic

Question 4

phenylisopropylamine

Answer 4

synthetic sympathomimetic with isopropylamine in its structure (eg, amphetamine, ephedrine).
Unlike catecholamines, phenylisopropylamines usually have oral activity, a long half-life, CNS
activity, and cause release of stored catecholamines

Question 5

Selective ` or a

adrenoceptor agonist

Answer 5

Drugs that have relatively greater effects on α or β adrenoceptors; none are absolutely selective or
specific

Question 6

Sympathomimetic:

A drug that mimics stimulation of the sympathetic autonomic nervous system

Answer 6

Reuptake inhibitor An indirect-acting drug that increases the activity of transmitters in the synapse by inhibiting their
reuptake into the presynaptic nerve ending. May act selectively on noradrenergic, serotonergic, or
both types of nerve endings

Question 7

Most vascular smooth muscle Contracts (↑ vascular resistance)
Pupillary dilator muscle Contracts (mydriasis)
Pilomotor smooth muscle Contracts (erects hair)
Bladder trigone, prostatic smooth muscle Contraction
Liver (in some species, eg, rat) Stimulates glycogenolysis

Answer 7

ALPHA 1 antagonists
