The modern concept of treatment of infectious urogenital lesions is based on purposeful etiotropic and pathogenetically justified prescription of effective drugs. At the same time, the correct choice of medical tactics and appropriate pharmacotherapeutic agents, considering the specific features of the pathology, becomes of paramount importance. For the successful implementation of this direction, the use of active pharmaceutical ingredients is promising, which, along with a wide range of antibacterial and antimycotic effects and a minimum level of toxicity, does not cause the appearance of resistant strains of sexually transmitted pathogens. The creation of effective, complementary and accessible for practical medicine vaginal dosage forms based on innovative compounds containing halide substituents will increase the efficiency of venereal care and improve the reproductive health of the population of Ukraine.

The aim of this work is to determine the optimal amount of ciminal in vaginal suppository compositions.

Materials and methods. The effect of the mass fraction of ciminal in vaginal suppositories was evaluated on model polyethylene oxide carrier compositions with the addition of 0.05 ml of dimexide, which, according to the literature, increases its solubility and degree of antimicrobial activity. The amount of ciminal in the studied vaginal dosage forms was 0.01–0.15 g, taking into account the average suppository weight of 3 g. The study was conducted using a mathematical plan of one-factor analysis of variance with repeated observations. As an optimization parameter, the level of specific activity of experimental suppository masses was used, which was evaluated by diffusion into agar against gram-negative Pseudomonas aeruginosa and Candida albicans fungi, the lesion of which urethral pathways is a serious clinical problem, considering their prevalence and high resistance to pharmacotherapy.

Results. It was found that the studied vaginal suppositories containing different amounts of ciminal exhibit a sufficiently high level of antibacterial and antimycotic activity, the level of which increases with increasing dose of the active substance.

Conclusions. Studies of the antimicrobial activity of suppository compositions with ciminal prove that their effectiveness is statistically significantly influenced by the mass fraction of the active pharmaceutical ingredient. It was found that the optimal level of antimicrobial activity of the soft vaginal dosage form provides a mass fraction of ciminal in an amount of 0.15 g, taking into account the average mass of suppositories of 3 g.
