18
Q

increase hr, cardiac output and BP; increase blood glucose; bronchiolar dilation and mydriasis

A

symmpathetic adrendergic

19
Q

decrease hr and BP; increase gastric motility and secretions (saliva); urination and defecation; bronchiolar and pupillary constriction(miosis)

A

parasympathetic cholinergic

20
Q

drug class of pilocarpine(salagen)

A

parasympathomimetic(cholinergic agonist)

21
Q

neurotransmitter and effect of pilocarpine

A

acetylcholine; acts like parasym; salivation, sweating, miosis, etc

22
Q

use of pilocarpine

A

glaucoma, myasthenia gravis, increase GI motility, reverse urinary retention

23
Q

what drugs are anticholinergic drugs(cholinergic blockers; parasympatholytic)

A

atropine, scopolamine, ipratropium(atrovent)

24
Q

nt and effects of atropine and scopolamine, atrovent

A

nt- blocks actions of acetylcholine receptors; symp effects-xerostomia, dry skin, mydriasis, increase hr, decrease gi motility

25
Q

use of anticholinergic drugs

A

peroperative meds; decrease salivation, bronchial mucous

26

dries up saliva

A

atropine

27

cardiac drugs prazosin/minipress; tetrazosin(hytrin) doxazosin(cardura)

38
Q

what do alpha blockers NT

A

block alpha receptors which prevents epi and norepi

39

effect of alpha blockers

A

block vasoconstriction in skin, decrease bp

40
