Glaucoma Drugs Flashcards
Alpha-agonists used for glaucoma?
Epinephrine, brimonidine
B-blockers used for glaucoma?
Timolol, betaxolol, carteolol
Diuretic used for glaucoma?
Acetazolamide
Cholinemimetics used for glaucoma?
Direct–pilocarpine, carbachol; indirect–physostigmine, echothiophate
Prostaglandin used for glaucoma?
Latanoprost (PGF2a)
MOA of epinphrine?
Decreases aqueous humor synthesis via vasoconstriction
MOA of brimonidine?
Decrease aqueous humor synthesis
MOA of B-blockers?
Decrease aqueous humor secretion
MOA of diuretics?
Decrease aqueous humor secretion via lowering HCO3- (by inhibiting carbonic anhydrase)
MOA of cholinomimetics?
Increase outflow of aqueous humor via contraction of ciliary muscle and opening of trabecular meshwork
What is used in emergencies?
Pilocarpine–very effective at opening meshwork into canal of Schlemm
MOA of latanoprost?
Increase outflow of aqueous humor
What drug is contraindicated in closed angle glaucoma?
Epinephrine
Which drug may darken the color the iris (browning)?
Latanoprost
Drugs that decrease aqueous humor SYNTHESIS?
1) Alpha agonist
2) B blockers
3) Acetazolamide
