Paper Abstract

This article is an attempt to analyze the concept, distinguishing features and possible application of photo- pharmaceutical therapy (PPT). Besides photopheresis, PUVA, and photodynamic therapy, PPT also embraces a broad spectrum of various combinations of light and drugs. PPT techniques can be classified according to the role of light in drug therapy into several groups: 1) Light activation of drugs before, during or after their administration, 2) light activation of cells of biotissue to potentiate the pharmaceutical effect of drugs, 3) light assisted drug delivery, 4) optical sensing of drug action at cellular and subcellular levels, and 5) selective photochemistry of drugs during their manufacturing. PPT seeks to describe the mechanisms of light-drug interaction, to time and sequence light-drug action, and to verify their synergetic effect. This article yields the results of developing new PPT modifications created in collaboration with some Russian scientific institutes and medical centers. The developed modifications are as follows: 1) drug pre-administration photoactivation, 2) antibody-photoconformation photoimmunotherapy, 3) photophonophoresis with a blend of photosensitizers and antibiotics, 4) photoelectrophoresis, 5) drug effect enhancement due to laser-induced blood circulation activation, 6) photoimmunization with alpha- fetoprotein, 7) photo-pharmaceutical dosimetry, and 8) a rapid drug toxicity photoassay.
