OBJECTIVE: To evaluate dorzolamide hydrochloride in patients younger than 6 years who have an elevated intraocular pressure or glaucoma.
DESIGN: A 3-month, controlled, randomized, double-masked, multicenter, clinical trial. Patients were randomized to 2% dorzolamide 3 times daily or timolol maleate gel-forming solution (0.25% for patients <2 years and 0.5% for patients > or =2 but <6 years) once daily plus placebo twice daily. If the intraocular pressure was not controlled through monotherapy, younger patients received concomitant dorzolamide 3 times daily and 0.25% timolol gel-forming solution once daily and older patients received a fixed combination of 2% dorzolamide and 0.5% timolol twice daily. The primary safety variable was the proportion of patients who discontinued therapy for a drug-related adverse experience. Intraocular pressure reduction was a secondary measure.
RESULTS: One younger patient (1.8%) of 56 randomized to dorzolamide discontinued concomitant therapy because of bradycardia. Two older patients (3.0%) of 66 discontinued dorzolamide because of ocular adverse experiences. The most frequent ocular adverse experiences were discharge and ocular hyperemia (younger cohort) and ocular hyperemia and burning/stinging (older cohort). At week 12, the mean change in intraocular pressure for dorzolamide was statistically significant from baseline (-7.3 mm Hg [-20.6%] and -7.1 mm Hg [-23.3%]) in the younger and older cohorts, respectively; P<.001 for both.
CONCLUSION: Dorzolamide was generally well tolerated and demonstrated efficacy for up to 3 months in patients younger than 6 years.
