Abstract
A number of microemulsions based on oleic acid and Tween 80, modified with piperidinium surfactants, have been obtained and characterized. The effect of additives on the size, stability, and solubilization effect of the formed systems with respect to hydrophilic (rhodamine B) and hydrophobic (indomethacin) substances was studied. By varying the ratio of components, it was possible to form microemulsions that differ greatly in viscosity: from easy-flowing compositions to gels. The kinetic parameters describing release process of substrates from microemulsions have been obtained. In vivo tests of the anti-inflammatory action of microemulsions loaded with indomethacin have shown that the presence of piperidinium surfactants enhances the therapeutic effect of the drug.
