4 Drug and Medication Information
4.1 Drug Indication

Trioxsalen is a pigmenting photosensitizing agent used in conjunction with ultraviolet light in the treatment of vitiligo.


5 Pharmacology and Biochemistry
5.1 Pharmacology

Trioxsalen ispharmacologically inactive but when exposed to ultraviolet radiation or sunlight it is converted to its active metabolite to produce a beneficial reaction affecting the diseased tissue.


5.2 MeSH Pharmacological Classification

Photosensitizing Agents

Drugs that are pharmacologically inactive but when exposed to ultraviolet radiation or sunlight are converted to their active metabolite to produce a beneficial reaction affecting the diseased tissue. These compounds can be administered topically or systemically and have been used therapeutically to treat psoriasis and various types of neoplasms. (See all compounds classified as Photosensitizing Agents.)
