A standard protocol for phototoxicity testing

Abstract
Based on experience accumulated in a number of laboratories, a standardized protocol for phototoxicity testing in experimental animals by the dermal route is presented. By conducting a limited interlaboratory study, demonstrating a high degree of consistency using 8-methoxypsoralen {8-MOP) and acridine, the sensitivity and reproducibility of the proposed methodology is demonstrated. Important aspects of performing phototoxicity testing are discussed.
