“…The combination of pentazocine and diazepam has been used in numerous other fields. It has been used in dentistry (Brown et al 2 and Main 5 ) in gynaecology (Schoenfeld et al 6 ), in cardiovascular surgery (Hatano et al 4 ), as premedication for bronchoscopy (Bernard 1 ) and as premedication for endoscopy in general (Choffat et al 3 ).
