Pharmocology Unit 1 Flashcards
cimetidine
inhibit drug metabolism (CYPs), inhibit excretion (competitive inhibitor organic cation transport in kidney tubule and liver)
phenobarbitol
stimulate drug metabolism
probenicid
competitive inhibitor organic anion transporter, inhibit drug secretion into kidney tubule and liver and excretion
ethanol
stimulate drug metabolism (CYPs)
bethanechol
synthetic choline ester; M selective; increase action time; stimulate smooth muscle post/op (GI, bladder, saliva)
carbachol
synthetic choline ester; increased action time; wide-angle glaucome -> increase humour drainage
methacholine
synthetic choline ester; M selective; decrease tachycardia, test bronchiol hyperactivity
muscarine
natural alkaloid; Muscarinic agonist
pilocarpine
natural alkaloid; muscarinic agonist; wide-angle glaucoma, increase saliva (anti-parkinson)
