Effect of pretreatment with ranitidine on the hypnotic action of single doses of midazolam, temazepam and zopiclone. A clinical study.
Patients receiving midazolam, temazepam or zopiclone by mouth as premedication for minor gynaecological surgery were pretreated with either ranitidine or an inert tablet. Pretreatment with ranitidine was associated with a greater degree of drowsiness at 20 and 40 min after midazolam, and a shorter mean time to peak hypnotic effect than in the non-pretreated group. Ranitidine did not affect the degree of drowsiness in the patients receiving temazepam or zopiclone.
