  • At frog neuromuscular junctions immersed in solutions containing 0.5 mM Mn2+, verapamil (40 microM) reduced the increase in miniature end-plate potential (MEPP) frequency produced by tetanic stimulation (50 Hz, 2 min) of the motor nerve to 5% of that in the absence of verapamil. In solutions containing 5 mM Mg2+, verapamil reduced the tetanic increase in MEPP frequency to 8% of that in the absence of verapamil. Verapamil added to solutions containing 0.15 mM Ca2+ decreased the tetanic rise in… CONTINUE READING
