41c - Occular Pharm Flashcards
What response will an adrenergic agonist have on ciliary epithelium?
aqueous production
What effect will opiates have on pupils?
pinpoint pupils. They block the effects of inhibitory neurons, resulting in unregulated cholinergics (meiosis)
What is gardener’s eye?
Datura or Angel trumpet plants release alkaloids like scopalmine and atropine that cause fixed pupil dilation
MOA of dipivefrin?
prodrug for epinephrien for glaucoma management. converted by local esterase
MOA of latanoprost?
prodrug for prostaglandin F2 (PGF2). used for glaucoma mangement. Converted by Esterase
MOA of atropine
muscarinic antagonist.
MOA of homotropine
muscarinic antagonist
MOA of tropicamide
muscarinic antagonist
MOA of cyclopentolate
muscarinic antagonist
MOA of scopalamine
muscarinic antagonist
ADE of muscarinic antagonists?
increased intraocular pressure, transient sting.
Systemic effects of dry mouth, photophobia, tachycardia, palpitations, headache, somnolence
CI in glaucoma due to pressure and sulfite allergies
MOA of latanoprost
prostaglandin analog, used for glaucoma
MOA of travoprost
prostaglandin analog, used for glaucoma
MOA of bimatroprost
prostaglandin analog, used for glaucoma
MOA of timolol maleate
B-receptor antagonist, used for glaucoma
MOA of levobunolol
B-receptor antagonist, used for glaucoma
MOA of metipranolol
B-receptor antagonist, used for glaucoma
MOA of carteolol
B-receptor antagonist, used for glaucoma
MOA of dorzolamide
carbonic anhydrase inhibitor. used for glaucoma.
Reduces bicarb secretion and thus fluid transport, decreasing intraocular pressure.
MOA of brinzolamide
carbonic anhydrase inhibitor. used for glaucoma.
Reduces bicarb secretion and thus fluid transport, decreasing intraocular pressure.
ADE of PGF2 analogs?
acute blurred vision, burning stinging/itching.
Chronic - slow and permanent brown pigmentation of iris, eyelid and eyelashes along with increased growth
MOA of carbonic anhydrase inhibitors?
localized irritation, burning, bacterial contamination.
Blurred vision, lacrimation, photophobia, xerophthalmia(no tears), sulfa allergies!
MOA of carbachol
muscarinic agonist and cholinesterase inhibitor. increases aqueous humor flow
MOA of pilocarpine
muscarinic agonist and cholinesterase inhibitor. increases aqueous humor flow
MOA of acetylcholine HCL
muscarinic agonist and cholinesterase inhibitor. increases aqueous humor flow
MOA of echothiophate
muscarinic agonist and cholinesterase inhibitor. increases aqueous humor flow
ADE of antiVEGF?
arterial thromboembolic evetnts.
MOA of verteporfin?
IV non-thermal laser-activator that generates free radicals and generates vessel damage and platelet activation and occlusion.
ADE of verteporfin
headache, visual disturbances, photosensitization (avoid light for 5 days)
