Direct-acting cholinergic agonist. Used to treat dry mouth (xerostomia) in patients with Sjogrens. Contraindicated in asthma patients.

6

What kind of drug is Pilocarpine? Use?

Direct mAChR agonist. Used to treat xerostomia, for miosis and glaucoma.

What drug class is Ephedrine in? Use?

Indirect adrenergic agonist (releases stored catecholamines). Mild stimulant, used for hypotension, decongestion, anaphylaxis.

24

What kind of drug is Cocaine? Effects?

Indirect adrenergic agonist, inhibits NE/dopamine reuptak (via blocking MOT). Causes adrenomimetic action.

25

What drug class are the amphetamines? Use?

Indirect adrenergic agonists, reverse DA/NE re-uptake and increse release. Used for ADHD, obesity.

26

What receptors does NE act on? Result?

a1-a2, b1. NOT b2, increases HR, vasoconstriction but no bronchodilation or vasodilation.
