Lidocaine's influence on the accumulation and depletion rates of mouse brain amines.

Mouse brain was analyzed for serotonin, norepinephrine, and dopamine. Pargyline plus lidocaine treatment caused an increased accumulation rate of serotonin over one hour compared to pargyline controls. alpha Methyl-p-tyrosine plus lidocaine treatment caused a decreased depletion rate of dopamine over four hours compared to rates of alpha methyl-p-tyrosine controls, and no difference for norepinephrine.
