title: [Study of analgesic effect of novel imidazoline derivatives and their effect on arterial pressure during pain].
abstract: In rat experiments new imidazoline derivatives caused a pain-relieving effect and inhibited a rise in arterial pressure in pain. Fluoride derivatives of imidazoline in doses of 1, 2, and 4 mg/kg induced long-term analgesia, had no effect on the background arterial blood pressure (AP), and significantly reduced its nociceptive pressor responses. The bromide derivatives of imidazoline showed no noticeable pain-relieving activity but reduced the nociceptive AP shifts. The background AP parameters did not change in this case. The prospects of directed chemical modification of imidazoline derivatives to obtain new analgesics capable of reducing the undesirable hemodynamic manifestations of pain are discussed.
