PHXA34 - A PROSTAGLANDIN-F2-ALPHA ANALOG - EFFECT ON INTRAOCULAR-PRESSURE IN PATIENTS WITH OCULAR HYPERTENSION

PhXA34, a prostaglandin analogue, was given topically to 40 patients with untreated ocular hypertension in a double masked randomised study. One single dose of 0.3, 1, 3, 10-mu-g, or placebo (vehicle) was given to one eye of each patient. A dose related IOP reduction ranging from 11 to 35% was observed with a maximal effect with 3 and 10-mu-g PhXA34. No hyperaemia was seen except after 10-mu-g PhXA34, where a mild to moderate hyperaemia was seen from 8 hours with a duration of up to 24 hours. Mild foreign body sensation in the PhXA34-treated eye was noted by three patients. No cells or flare were seen.
