[The effect of verapamil on the dynamics of decrease in the brain levels of phosphorus macroergs during ischemia studied by 31P-NMR in vivo].

Protective effects of verapamil on dynamics of phosphorus-containing metabolites were studied during 30 min complete ischemia by means of 31P NMR. Verapamil appears to decrease the ATP and creatine phosphate pools consumption in ischemic brain tissue. The efficiency of the drug depended on the administration procedure and was not similar in two different models of ischemia. Possible mechanisms of the verapamil effect on bioenergetics of nervous tissue are discussed.
