Meclonazepam [ ( S ) -3-methylclonazepam ] is a chemical compound from the group of benzodiazepines , which was developed by Hoffmann-La Roche in the 1970s . It is similar in structure to clonazepam . This benzodiazepine, which, in addition to its sedative and anxiolytic effects, is also effective in high doses against schistosomiasis , was never commercially available. It is now offered on the Internet as a designer drug.
