Development of a Phototoxicity Testing Strategy for Accurate Photosafety Evaluation of Pharmaceuticals Based on the Assessment of Possible Melanin-Binding Effects.

Int J Toxicol 2018 Jul/Aug;37(4):296-307. Epub 2018 Jun 13.

1 Charles River Laboratories Den Bosch B.V., DD 's-Hertogenbosch, the Netherlands.

Drug-induced phototoxicity occurs when drugs absorb natural sunlight, leading to chemical reactions causing cellular damage. Distribution to light-exposed tissues is critical and is enhanced by binding to melanin. The International Council on Harmonization S10 guidance document on photosafety evaluation of pharmaceuticals states that although nonpigmented skin tends to be more sensitive than pigmented skin, pigmented skin models should be considered for drugs that bind significantly to melanin.

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

Antihypertensive drugs and risk of skin cancer.

G Ital Dermatol Venereol 2018 Oct 24;153(5):672-684. Epub 2018 Jan 24.

Institute of Dermatology, Fondazione Policlinico Universitario A. Gemelli, Catholic University of Rome, Rome, Italy.

The potential carcinogenic risk of antihypertensive drugs has been examined in several studies that reported controversial results. The association between treatment with antihypertensives and risk of skin cancer has also been questioned, considering the long-term administration of such drugs and the ability of some agents to cause photosensitive reactions. In fact, experimental and epidemiologic findings suggest a link between drug-induced photosensitivity and skin cancer, possibly through the induction of DNA damage in predisposed individuals.
