vaginal mucosa - Opis:
- The investigated powders on a methylcellulose base revealed good adhesion to the vaginal mucosa and were present on it throughout the daily activities of the patient. This property enabled the continuity of the 24-hour action of the drug. The treatment of vagina inflammatory conditions is usually long and difficult because of the frequent relapse. Powders were transformed into gels and were tested for their properties. Formulations were prepared with varying pH and rheological properties. The test showed the work of adhesion of gels. All gels with ratios of lactic acid to chitosan of 1:1 and 2:1 showed a pH in the physiological range at 37°C. Additionally, carboxymethylcellulose sodium salt and excipients allow 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 carboxymethylcellulose sodium salt in comparison to gels without carboxymethylcellulose sodium salt.
