title: The effect of systemic tocainide, lidocaine and bupivacaine on nociception in the rat.
abstract: 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.
