The effect of verapamil on resting oxygen metabolism of human peripheral blood polymorphonuclear granulocytes

: It was found that 0.051 mmol/l concentration of verapamil inhibits the resting (spontaneous) oxygenic metabolism of the human peripheral blood polymorphonuclear granulocytes. In experiments in vitro it was expressed by the statistically significant lower capacity to reduction of nitroblue tetrazolium (NBT) by the granulocytes incubated with the verapamil solution in comparison with the same capacity without the verapamil solution.
