Reaction of the Physiological IOP in Rabbits after Application of the Latanoprost(Xalatan) and Amino Acid L-arginin.HCl Mixture

Overview

Authors present results of series of experiments focused to influence the IOP byantiglaucomatics in rabbits (New Zealand White) with physiological IOP. Addingof the 10% amino acid L-arginin.HCl to the 0.005% Xalatan eye drops intensifiesactivity of antiglaucomatics resulting in 9.5% average reduction of the IOP ina four-hour experiments (with maximum in 15th min. - 19.3%), compared withapplication of both substances alone. Size of the pupil was not affected. Based onour experimental results we assume that the increased activity of the 0.005%Xalatan mixture with 10% amino acid L-arginin.HCl created a new completemetabolite – „bio-antiglaucomaticum“. According to our observations this metabolitecaused increase of the uveo-scleral outflowleading to the striking reductionof the physiological IOP in rabbits.
