Continuing the implementation of research on the problem of treatment of vaginal pH disorders, intravaginal globules were examined as vaginal drug form which carries the lactic acid complexes with chitosan. The intravaginal application of globules that transform into gel under natural conditions is aimed at achieving the physiological pH of the vaginal environment. Formulations were prepared with varying pH and rheological properties. The test showed the work of adhesion of gels. All gels with ratios of 1:1 and 2:1 of lactic acid to chitosan showed a pH in the physiological range at 37°C. Additional hydroxypropylmethylcellulose and excipients allows various formulations with a wide range of pH to be obtained. Rheological investigation revealed an increase in the dynamic viscosity of preparations containing lactic acid complexed with chitosan and hydroxypropylmethylcellulose in comparison to the gels without hydroxypropylmethylcellulose. The study of the work of adhesion showed the effect of hydroxypropylmethylcellulose and their concentration on the value of the work of adhesion.
