METHOD FOR DETERMINING MAXIMUM CONCENTRATION TIME OF PHOTOSENSITIZER CHLORIN E6 LYSINE DIMEGLUMINE SALT IN TUMOR Russian patent published in 2020 - IPC A61B6/00 A61K49/00 A61K31/409 A61N5/06 A61P35/00 

FIELD: medicine.

SUBSTANCE: invention refers to medicine, namely to oncology, and can be used to determine time of reaching maximum concentration of photosensitizer (PS) of chlorine series – chlorine e6 lysine dimeglumine salt in body tissues after its introduction. PS chlorin e6 lysine dimeglumine salt is introduced into the body. 30 minutes after the PS administration, a tumor / standard fluorescent contrast value is calculated. If the tumor / standard fluorescent contrast is up to 3.0, the maximum PS accumulation in the tumor is considered to be 3 hours from the moment of PS administration, with the tumor / standard fluorescent contrast more than 3.0–4 hours.

EFFECT: method provides higher clinical effectiveness ensured by possibility of individual determination of time of maximum accumulation of PS chlorine e6 dimeglumine salt in tumors.
