The Uses of 1,2,2,6,6-PENTAMETHYLPIPERIDINE
ganglionic blocker, antihypertensive
The Uses of 1,2,2,6,6-PENTAMETHYLPIPERIDINE
Pharmacological evaluation of the antagonism of nicotine's central effects by mecamylamine and pempidine where pempidine was found to increase the ED50 of nicotine (0.73 mg/kg) for depression of spontaneous activity in a dose-related manner. At a dose of 3 mg/kg, pempidine increased nicotine's ED50 4.7-fold.
