Anti glaucoma drugs Flashcards
What is uveoscleral outflow?
Through spaces between bundles of ciliary muscle
selectively increase uveoscleral outflow
prostanoid FP Receptor agonist
Alters trabecular and uveoscleral outflow
bimatropost
what inhibits aqueous humor secretion
adrenergic agents
B2-subject to desensitization
alpha (clonidine)–lots of SEs
brimonidine (alpha2)
Brimonidine functions
alpha 2 agonist
inhibits aqueous humor secretion
increases uveoscleral outflow
protect against loss of retinal cells
Beta adrenoceptor antagonists–most common drug? concerns?
Timolol
concern in patients with respiratory disease
carbonic anhydrase inhibitors
- target the catalytic formation of HCO3 which is the driving force for aqueous humor secretion
- acetazolamide
- dorzolamide
pilocarpine MOA
- increases P-dependent aqueous humor outflow via the trabecular meshwork
- M3 mACH mediated contraction of ciliary muscle–causes widening of trabecular meshwork spaces
- SEs–miosis, spasm of accommodation, brow ache
prostanoid FP Receptor agonist
- latanoprost
- travoprost
- enhances uveoscleral outflow
prostamide
- bimatropost–prostaglanding F2 analog
- enhances uveoscleral outflow
B2 Adrenoceptor agonist–secretion, trabecular outflow, uveoscleral outflow
- secretion–decreases
- trabecular outflow increases
B1 adrenoceptor antagonists–secretion, trabecular outflow, uveoscleral outflow
-secretion decreases
alpha 2 adrenoceptor agonists–secretion, trabecular outflow, uveoscleral outflow
- decrease secretion
- increase uveoscleral outflow
carbonic anhhydrase inhibitors–secretion, trabecular outflow, uveoscleral outflow
-decrease secretion
muscarinic ACh R agonists–secretion, trabecular outflow, uveoscleral outflow
-increase trabecular outflow
