Where does cyclobenzaprine come from?
Cyclobenzaprine—fully called cyclobenzaprine hydrochloride, or C20H22ClN—was first synthesized in 1961 by the pharmaceutical company Merck & Company. It is chemically related to tricyclic antidepressants, an early form of antidepressants invented in the 1950s.
Although cyclobenzaprine was found to have limited efficacy as an antidepressant, it proved very effective as a muscle relaxant. In 1977, it was approved by the US Food and Drug Administration (FDA) for treatment of muscle spasms. It is still manufactured by Merck & Company under the brand name Flexeril and is distributed by McNeil Consumer & Specialty Pharmaceuticals.
While largely used to treat muscle spasms and pain, cyclobenzaprine has also been effective in treating the symptoms of fibromyalgia and tension headaches. Side effects of cyclobenzaprine include drowsiness, which leads to its occasional use as a sleep aid.
Although cyclobenzaprine is not a controlled substance, it is only available by physician prescription. Though not considered physically addictive, its relaxing properties may create psychological dependencies upon longterm use. Overdose may cause heart problems.
Cyclobenzaprine is less widely abused than other drugs such as certain painkillers like OxyContin, but it is still illegally obtained and abused to get a relaxing “high.” Cyclobenzaprine and Flexeril made headlines though in 2012 when toxicology reports found the drug in singer Whitney Houston’s system upon her overdose.
