[Dependence of antimicrobial effect of micelle-capsulated therapeutics on the micelle size].

With the method of dynamic light scattering it was shown that the average size of micelles in the series of formulations based on various clindamycin salts, i. e. ClindHCl+Tween-20, ClindBz+Tween-20, ClindHCl+Cremafor-EL and ClindBz+Cremafor-EL increased from 6 to 20 nm. Investigations with the agar diffusion method revealed that the bactericidic action of the micelle-capsulated therapeutics did not depend on the micelle size within 6 to 20 mn. The concentration of the micellar clindamycin or gentamicin equal to 0.05 mcg/ml was bacteriostatic with respect to Micrococcus (Sarsina) luteus.
