A dose-response study of piloplex for duration of action

The duration of reduction in intraocular pressure after single-dose administration of three concentrations of piloplex and the vehicle of the drug was evaluated in 12 patients with open-angle glaucoma in a randomized, double-masked, crossover study. Piloplex lowered intraocular pressure in a dose-related fashion, with a duration of action of at least 14 hours.
