Ophthalmic drug films in the therapy of experimental herpetic keratoconjunctivitis

Abstract

Introduction. The complexity of the treatment of herpetic keratoconjunctivitis is due to the severity of the disease, complications, the transition to chronic relapsing forms and the insufficient effectiveness of the drugs used, which leads to a steady increase in the number of patients. The aim of the study was to evaluate the therapeutic efficacy of the eye drug films «GlazAvir» in the experimental model of acute herpetic eye infection in rabbits. Research objectives: to study the specific activity of «GlazAvir» and compare the long-term indicators of the level of manifestation of individual clinical signs of keratoconjunctivitis. Material and methods. In the work we used rabbits of the Chinchilla breed, the herpes simplex virus type 1 and the eye drug films «GlazAvir». A model of ophthalmic herpetic infection was formed by infection of rabbits with virus-containing material of a pre-scarified eye cornea against the background of local anesthesia. Аnimals were treated with the drug «GlazAvir» - 1 application per day for 7 days. Animals were observed daily for 15 days, then every 3 days until the 25th day of observation. The effectiveness of the drug was evaluated at the peak of the development of the pathological process. Results and discussion. There was a decrease in mortality from 50 to 20%, and an increase in average life expectancy by 27.87%, compared with the control in animals treated with «GlazAvir». It was noted after activation of herpetic keratoconjunctivitis on the 2nd – 5th day, at the peak of the disease (6–9th day) a statistically significant decrease in the activity of the pathological process (p0.05) by rabbits treated with the «GlazAvir» ophthalmic drug films. The tendency to normalization by the rabbits treated with the «GlazAvir» preparation was observed until the 14th day. Conclusion. The data obtained indicate the pronounced effectiveness of the «GlazAvir» preparation in the treatment of experimental herpesvirus keratoconjunctivitis.
