    Drug-Induced Photosensitivity - a Continuing Diagnostic Challenge.
    Acta Clin Croat 2017 Jun;56(2):277-283
    Clinical Department of Dermatovenereology, Sestre milosrdnice University Hospital Center, Zagreb, Croatia.
    When taking different drugs, their possible side effects on the skin should be considered, including skin reactions connected to photosensitivity. This photosensitivity caused by drugs can appear as phototoxic reactions (which occur more often) or photoallergic reactions (which occur less often and include allergic mechanisms). The following drugs stand out as medications with a high photosensitivity potential: nonsteroidal anti-inflammatory drugs (NSAIDs), cardiovascular drugs (such as amiodarone), phenothiazines (especially chlorpromazine), retinoids, antibiotics (sulfonamides, tetracyclines, especially demeclocycline and quinolones), etc. Read More

    Exploratory and regulatory assessments on photosafety of new drug entities.
    Curr Drug Saf 2012 Apr;7(2):140-8
    Department of Pharmacokinetics and Pharmacodynamics, School of Pharmaceutical Sciences, University of Shizuoka, Suruga-ku, Japan.
    Drug-induced phototoxicity is elicited after exposure of the skin and/or eyes to topically or systemically administered pharmaceutical substances, followed by exposure to sunlight. This undesirable side effect is one of the impediments in drug discovery and development, and substantial efforts have been made to avoid drug-induced phototoxic reactions. To evaluate the phototoxic potential of compounds, effective methodologies have been developed over the past few years, and screening strategies have also been proposed for predicting in vivo phototoxic reactions.
