Intravenous premedication with diazepam. A comparison between two vehicles.

Two preparations of diazepam, Valium Roche mixed Micelles and Diazemuls, were compared as intravenous premedicants in 119 patients undergoing minor gynaecological surgery. There were no differences between the formulations with regard to anxiolytic effects and systemic tolerance. There were no symptoms typical of thrombophlebitis in the Valium Roche Mixed-Micelles group and only one case in the Diazemuls group. Acute local tolerance was similar with both trial drugs and superior to conventional diazepam preparations. Based on the favourable results of the present study it can be concluded that such vehicles should be considered for any injectable preparation with a known tendency to produce venous irritation.
