The role of general practitioner research groups in the study of benzodiazepines.

The advantages of a once a day regime of a long half life benzodiazepine are illustrated by a general pratitioner study in the U.K., which showed that in a group of over 100 patients, clorazepate 15 mg nocte was equally as effective as diazepam 5 mg three times a day. Another study carried out on 50 patients randomly allocated to lorazepam 1 mg t.d.s. or to clorazepate, which was directly related to the low incidence of side effects and simplicity of dosage.
