Abstract

The authors compared the additive intraocular pressure (IOP)-lowering effects of two different topical medications, apraclonidine hydrochloride and dipivefrin hydrochloride, when used in conjunction with timolol maleate. Eighteen patients with elevated IOPs entered a randomized, double-masked, cross-over study. Each used apraclonidine 1.0%, dipivefrin 0.1 %, or placebo, twice daily for 3 weeks each, in addition to timolol 0.5% twice daily. Only apraclonidine produced a significant additional IOP lowering over timolol treatment alone at all time intervals (P < 0.001). Its additive effect was significantly greater than that seen with dipivefrin at all time intervals (P < 0.01), with the exception of day 22 (P = 0.061). No significant change in pulse rate or blood pressure was seen during apraclonidine administration. Apraclonidine may be a useful adjunctive agent in patients with poorly controlled glaucoma.
