Research on the composition development of suppositories with echinacea and study of their stability

Abstract

The purpose of the work was to experimentally substantiate the composition and study the stability of extemporal suppositories with Echinacea, intended for use in complex therapy and prevention of genitourinary diseases. Materials and methods. The object of the study was samples of suppositories made by pouring using liquid Echinacea extract as an active pharmaceutical ingredient. Cocoa butter, Witepsol H15 and Witepsol W35 were used as suppository bases. The study was carried out using modern physicochemical, pharmaco-technological and microbiological methods. Results. On the basis of the carried out physicochemical and pharmaco-technological studies, it was found that in the manufacture of suppositories using liquid Echinacea extract, Cocoa butter or Witepsol can be used as a suppository bases. The main indicators of the quality of suppository samples were also studied: organoleptic characteristics, average weight, melting point, time of complete deformation, microbiological purity, meeting the requirements of the State Pharmacopoeia. Conclusions. As a result of the carried out physicochemical, pharmaco-technological and microbiological studies, a suppository base was selected for the creation of extemporal suppositories for the treatment and prevention of genitourinary diseases, the main quality indicators were established that meet the requirements of the State Pharmacopoeia of Ukraine, and the shelf life of the suppositories is 10 days.
