We evaluated experimental liquid and solid pharmaceutical formulations using specific enzymatic in vitro tests to reveal glutathione-reductase, catalase and NADPH-oxidase activity with an aim to choose the most promising formulations for further study and development of products for treatment of inflammatory conditions of the oral cavity. The above mentioned tests allow identification of substances with antimicrobial and immune stimulating activity respectively. Herbal extracts Eucalimin and Estiphan were used as reference products. As a result, differences in antimicrobial and immune stimulating activity of the formulations were found, and the most promising formulations were chosen for further study and development of products with antimicrobial and immune stimulating activity.
