ABSTRACT
Thiocolchicoside is a semisynthetic derivative of colchicine, a natural anti-inflammatory glycoside which originates from the flower seeds of Superba gloriosa. It is a muscle relaxant with anti-inflammatory and analgesic effects. This chapter provides monographs of thiocolchicoside which have caused contact allergy/allergic contact dermatitis. The monographs present: identification section; contact allergy (general population, patients with dermatitis, case reports and case series); cross-reactions; patch test sensitization; photocontact allergy; and immediate contact reactions (contact urticaria). The identification section presents IUPAC names, synonyms, CAS and EC numbers, structural and chemical formulas, Merck Index monographs, and advises on patch testing. The chapter also covers an extensive amount of information to benefit dermatologists, allergists, and all others interested in drug allergy.
