Oral lormetazepam in premedication. A comparison with diazepam.

Lormetazepam, a relatively new benzodiazepine was compared in a randomised, double blind trial with diazepam for its effectiveness as an oral premedicant drug. A scoring system was used to assess sedation, relief of anxiety, nausea, dizziness and cardiovascular effects in two groups of patients having orthopaedic operations. Some statistical indication that lormetazepam has a greater anxiolytic effect than diazepam was found, but in assessing total effect using a known scoring system, no difference was demonstrated between the two drugs.
