Mexazolam[1] (marketed under the trade names Melex and Sedoxil)[2] is a drug which is a benzodiazepine derivative.[3] Mexazolam has been trialed for anxiety and was found to be effective in alleviating anxiety at one week follow-up, however, after three weeks of therapy mexazolam had lost its therapeutic anxiolytic properties becoming no more effective than placebo, presumably due to benzodiazepine tolerance.[4] Mexazolam is metabolised via the CYP3A4 pathway. HMG-CoA reductase inhibitors including simvastatin, simvastatin acid, lovastatin, fluvastatin, atorvastatin and cerivastatin inhibit the metabolism of mexazolam,[5] but not the HMG-CoA reductase inhibitor pravastatin.[6][7]
