Nifedipine and flunarizine block amphetamine-induced behavioral stimulation in mice

Sixteen calcium channel inhibitors (CCI's) were tested in a model utilizing amphetamine-induced behavioral stimulation in mice. Nifedipine, flunarizine and possibly PY 108-068 were effective in blocking amphetamine-induced locomotor stimulation. Verapamil, diltiazem and many other CCI's were ineffective in this experimental paradigm.
