Abstract
BACKGROUND: Despite the constant search for new medications for local prevention of surgical infection, the problem of purulent-inflammatory complications from postoperative soft tissue wounds remains relevant to this day.
AIM: To experimentally study the osmotic activity and anti-inflammatory properties of the developed xymedone-containing ointment composition levoxycol in comparison with the well-known ointment dioxomethyltetrahydropyrimidine + chloramphenicol (levomekol).
MATERIAL AND METHODS: The anti-inflammatory properties of the ointments were studied in vivo on 60 outbred male Wistar rats, which were divided into three groups, 20 animals each. The first group served as control. In the second group of animals, levomekol ointment was used, in the third group — levoxycol. An assessment of the osmotic activity of the experimental ointment composition levoxycol in comparison with a known drug was carried out in an in vitro experiment. To evaluate the anti-inflammatory activity of ointments, a model of carrageenan-induced edema of rat paws was used. To analyze differences in the frequency of the studied outcomes in groups of animals, the Mann–Whitney U test was used.
RESULTS: Osmotic activity showed that wipes soaked in ointment forms absorbed the following amount of contrast (Me [Q1; Q3]): levomekol — 28.2 (26.4; 31.3) ml; levoxycol — 41.8 (39.5; 43.4) ml (p=0.001). The anti-inflammatory activity of the ointment forms manifested itself in the form of suppression of swelling of the rats' paws at 3 and 5 hours after the injection of carrageenan. When using the ointment form of levomekol, the volume of displaced liquid with the introduction of carrageenan, starting from 3 hours, was 1.8±0.19 ml. When using the ointment form of levoxicol, the amount of displaced liquid when carrageenan was administered, starting from 3 hours, was 1.57±0.16 ml (p=0.013).
CONCLUSION: In vitro experiments have shown that the ointment form of levoxicol has a longer osmotic activity; experimental data in vivo indicated that the use of the developed ointment form of levoxicol, in contrast to the ointment form of levomekol, has a positive effect on the course of inflammatory processes in soft tissues in the first 2–3 hours by reducing the volume of displaced fluid.
