Abstract
The photodynamic activity and pharmacokinetics of a new liposomal form (LF) of the sensitizer Photosense based on aluminum sulfophthalocyanine salts have been studied in comparison to those of the standard form (SF) representing a 0.2% aqueous solution of the parent substance. The effective therapeutic doze of the LF of Photosense in mice bearing Ehrlich's tumor was 1 mg/kg, which is four times as small as the effective dose of the SF. The selectivity of accumulation in the tumor tissue 24 h after administration for the LF of Photosense was 1.5 times higher than for the SF. The drug accumulation in skin (determined by the fluorescence intensity) on the 7th days of experiment for the LF of Photosense was 1.6 times lower than for the SF. The pharmacokinetics of the LF of Photosense in mice without tumors significantly differs from the behavior of the SF.
