3.3.1.1 - Category: ADRENERGIC AGONISTS 40-42<br />
Generics<br />
Tradenames<br />
Non-selective: Dipivefrin 0.1% Propine, Epinal, d-Epifrin, Glaucothil<br />
Epinephrine 0.25-2.0%<br />
Epinephrine<br />
Alpha-2 selective: Apraclonidine 0.5-1.0% Iopidine<br />
Brimonidine 0.2%<br />
Alphagan<br />
Clonidine 0.125 -0.5%<br />
Isoglaucon, Catapres, Glaucopres<br />
Aruclonin, Clonidophthal<br />
Action<br />
Non-selective: Decreases aqueous humor production<br />
Increases aqueous humor outflow<br />
Alpha-2 selective:<br />
Apraclonidine<br />
Decreases aqueous humor production<br />
Maximum effect: 4-5 hours<br />
Duration of effect: 12 hours<br />
Reduces IOP 25-39% as monotherapy<br />
Is additive to timolol<br />
Additivity to maximum medical therapy<br />
Brimonidine<br />
Clonidine<br />
Decreases aqueous humor production<br />
Increases uveoscleral outflow<br />
Duration of effect: 12h<br />
Reduces IOP up to 27% as monotherapy<br />
Selectivity <strong>for</strong> α 2 vs α 1 adrenoceptors is 1000/1. This selectivity<br />
results in no mydriasis <strong>and</strong> the absence of vasoconstriction.<br />
Decreases aqueous humor production<br />
Duration of effect: 6-12 hours<br />
Little effect on pupillary diameter or accommodation<br />
Dosage <strong>and</strong> administration<br />
Non-selective: Dipivefrin 0.1% 2 times daily<br />
Epinephrine 0.25-2.0%<br />
3 times daily<br />
Alpha-2 selective: Apraclonidine 0.5-1.0% 2-3 times daily<br />
Brimonidine 0.2%<br />
2 times daily<br />
Clonidine 0.125-0.5%<br />
3 times daily<br />
Indications<br />
Non-selective: Dipivefrin 0.1% 2 times daily<br />
Elevation of intraocular pressure in patients<br />
where the IOP can be deleterious <strong>for</strong> the<br />
preservation of visual function.<br />
Epinephrine 0.25-2.0%<br />
3 times daily<br />
