The influence of variables of pharmaceutical factors on the technological processes of drugs manufacturing is incredibly important. Thus, in the development of a new drug in the form of medicinal films, the relevance and necessity of determining the effect of the methods of active substances adding on the effectiveness of the drug was determined.
The aim is rationalization of the method of the active pharmaceutical ingredients adding into the composition of the developed drug.
Materials and methods. As experimental samples we used medicinal films, which were made using various methods of active ingredients adding. The quality of the samples was evaluated by the antimicrobial activity against Clostridium sporogenes and Staphylococcus aureus, which was determined by the diffusion method in agar.
Results. The study of the antimicrobial activity of medicinal films with various methods of active ingredients adding showed that the adding of metronidazole as an aqueous solution increases the antimicrobial activity of the films by 21.23%, 16.89%, 28.59%, respectively, compared with films of similar composition, in which metronidazole was added as a suspension, and the remaining ingredients were added by the same way. The introduction of chlorhexidine bigluconate and glucosamine hydrochloride in the film-forming solution lastly together with the solution of metronidazole increases the antimicrobial activity by 24.67%, which is probably due to the absence of contact between thermolabile ingredients and solutions of film-forming substances having a high dissolution temperature.
Conclusions. The most rational is adding of metronidazole to the medicinal films in the form of a 0.01% aqueous solution in a mixture with the chlorhexidine bigluconate and glucosamine hydrochloride solution to the final film-forming solution.
