[Comparative evaluation of the tolerability of proxofelin and clofelin and their effects on the eye in patients with glaucoma].

Tolerance and effects of proxofelin (1% proxodolole and 0.25% clofelin) and clofelin were compared in 39 patients (50 eyes) with primary open-angle glaucoma by open and double-blind methods. Intraocular pressure, ocular hydrodynamics, arterial pressure, and heart rate were examined before and on day 28 of treatment. The hypotensive effect of proxofelin was more expressed than that of clofelin, the drugs decreasing intraocular pressure by 37 and 27% of the initial value, respectively. Proxofelin decreased ophthalmic tone, significantly increasing the coefficient of fluid discharge easiness by 50% and decreasing the production of aqueous humor by 51.9%, while clofelin slightly (14%) increased the coefficient of fluid discharge easiness and decreased intraocular pressure mainly at the expense of suppressing aqueous humor secretion. Hence, the combined drug is preferable in comparison with the monopreparation. Moreover, proxofelin was well tolerated by the patients, which differs it favorably from clofelin.
