EVELOPMENT OF THE COMPOSITION AND TECHNOLOGY OF ANESTHETIC EYE DROPS

Abstract

In modern ophthalmological practice, the use of local anesthetics for surface anesthesia of the eyeball becomes an integral stage in preparing the patient for diagnostic studies, therapeutic manipulations, surgical and laser interventions. The share of regional pain management methods is steadily increasing. However, at the same time, the list of requirements that local anesthetics must meet is also growing. According to them, the drug that combines high anesthetic activity and minimal toxicity should be considered the best. The local anesthetic anilocaine hydrochloride, developed according to the author's method in PGFA, exhibits high surface anesthetic activity with relatively low toxicity, and also has anti-inflammatory and moderate antimicrobial activity, which distinguishes it very favorably from the local anesthetics used and is an alternative to the use of expensive imported drugs. The purpose of this study is to develop the composition and technology of anesthetic eye drops. Materials and methods. The pharmaceutical substance anilocaine hydrochloride was used as a pharmacologically active component. The determination of the hydrogen index was carried out by the potentiometric method in accordance with the requirements of the OFS "Ionometry". To study the stability of eye drops, characterized by the indicator "Related impurities", a high-pressure liquid chromatograph "ShimadzuLCProminence" (Japan) was used. Statistical processing of the results of chemical studies was carried out according to generally accepted methods using standard EXCEL computer programs. Results and discussion. As a result of the conducted research, the composition of anesthetic eye drops based on anilocaine hydrochloride has been substantiated and developed. A technology for manufacturing eye drops has been developed to ensure the sterility of the resulting form. Conclusion. Based on technological and microbiological studies, the composition and technology of locally anesthetic eye drops based on anilocaine hydrochloride for surface (drip) anesthesia of the eyeball has been developed.
