Abstract
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.
期刊介绍：
Progress in the Chemistry and Application of Chitin and its Derivatives is an annual journal focused on all aspects of production, modification, enzymology and application of chitin and its many derivatives, including chitosan. The journal publishes full-length papers as well as invited reviews. To be considered, papers must present original research that has not been published or accepted for publication elsewhere. The language of the journal will be English.
