The analgesic properties of systemically administered tocainide, a primary amine congener of lidocaine with a longer duration of action, were examined in rats. Significant antinociception, as assayed on the hot-plate test, was observed after i.p. tocainide at doses below toxic levels. No antinociception was seen with non-toxic doses of lidocaine or bupivacaine.
在大鼠中研究了全身给药的妥卡尼（利多卡因的一种伯胺同系物，作用持续时间更长）的镇痛特性。腹腔注射低于中毒剂量的妥卡尼后，在热板试验中观察到显著的抗伤害感受作用。无毒剂量的利多卡因或布比卡因未观察到抗伤害感受作用。
