We investigated the antinociceptic effects of cilnidipine, a dihydropyridine derivative which acts on both L- and N-type voltage-dependent calcium channels, in mice. Intrathecally injected cilnidipine showed significant analgesic effect in formalin test. Cilnidipine significantly suppressed N-type currents in dorsal root ganglion (DRG) cells. Our findings apparently support the idea that cilnidipine attenuates synaptic neurotransmission by inhibiting N-type calcium channels in DRG neurons. (C) 2000 Elsevier Science B.V.
