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.

metric ratio of 1:1, 2:1, 3:1, 4:1 and 8:1. Their pH ranged from 3.92 to 4.44 for 1:1 gels and from 2.36 to 2.84 for the 8:1 ratio. The addition of 5% polyvinylpyrrolidone K-90 increased the pH from 4.28 to 4.52 for 1:1 and from 2.58 to 3.30 for the 8:1 ratio. The addition of 5% polyvinylpyrrolidone K-90 increased the dynamic viscosity from 84 to 510 mPa.s for 1:1 gels and from 47 to 386 mPa.s for the 8:1 ratio. The gels obtained from powders possess the work of adhesion - the energy needed to separate the gel from the probe was 15.2 g/s for gels with 5% polyvinylpyrrolidone K-15, 52.76 g/s for gels with 5% polyvinylpyrrolidone K-30, and 56.6 g/s for gels containing 5% polyvinylpyrrolidone K-90. The results proved that it is possible to produce a preparation with optimal pharmaceutical and application properties.

An important issue in the treatment of vaginitis is the amount of time the drug remains on the vaginal mucosa. If the contact time is too short, the drug cannot work effectively to ensure the correct pH in the vaginal environment. This study evaluated formulations of globules containing sodium alginate, lactic acid and chitosan with different pH and rheological properties. The experimental studies revealed that it is possible to produce a preparation with optimal pharmaceutical and application properties. The use of an appropriate ratio of lactic acid to chitosan in the complex and the appropriate concentration of sodium alginate produces a preparation with excellent properties to coat the surface of the vaginal mucosa.

The insufficient duration of the drug’s contact with the vaginal mucosa does not provide adequate pH, conditioning the physiological biocenosis of the organ. This effect is hampered by numerous anatomic and physiological conditions which do not facilitate prolonged contact of the drug with the application site. This study has shown the impact of the used excipients and the ratio of lactic acid to chitosan on pH, dynamic viscosity and adhesiveness of methylcellulose gels obtained from powders. The addition of sodium alginate and excipients to these complexes allows various formulations to be obtained over a wide range of pH. Rheological investigations revealed an increase in the dynamic viscosity of preparations containing lactic acid complexed with chitosan and sodium alginate in comparison to gels without sodium alginate. Studies of the work of adhesion showed the effect of glycerol, 1,2-propylene glycol and their concentrations on the value of the work of adhesion.

pH of gels ranged from 3.92 to 4.44 for gels 1:1 and from 2.36 to 2.84 for 8:1 ratio. The addition of 20%, 23% or 25% poloxamer 407 increases the pH ranged from 4.00 to 4.91 for gels with 1:1 ratio and from 2.56 to 3.42 for 8:1 ratio. Rheological studies demonstrated that the investigated gels obtained from powders have the dynamic viscosity ranged from 53 mPa*s to 398 mPa*s for the 1:1 stoichiometric ratio in the complex and from 19 mPa*s to 242 mPa*s for 8:1 ratio. The addition of calcium alginate with polyoxyethylene glycol-200 reduces the pH and maintains high dynamic viscosity. The thermosensitive gels obtained from thermosensitive powders shows high adhesion and are difficult to separate from the probe.
