Summary
Tizanidin, a new muscle relaxant which undergoes intensive biotransformation, can easily be screened by UV-photometry after extraction from alkaline medium with ethyl acetate. Absorption maxima in the range of 310 nm and 321 nm, respectively, could be observed in more than 60 cases after the ingestion of therapeutical doses. Other commonly used muscle relaxants such as baclofen, chlormezanon and tetrazepam revealed no maxima in this range.
