Metabolite Identification
Common Namedesmethylcyclobenzaprine
Descriptiondesmethylcyclobenzaprine is a metabolite of cyclobenzaprine. Cyclobenzaprine, brand name Flexeril, is a muscle relaxant medication used to relieve skeletal muscle spasms and associated pain in acute musculoskeletal conditions. It is the most well-studied drug for this application, and it also has been used off-label for fibromyalgia treatment. A new bedtime formulation of cyclobenzaprine is under development for the management of fibromyalgia syndrome. (Wikipedia)
