CLINICAL PHARMACOLOGY
Mepivacaine stabilizes the neuronal membrane and prevents the
initiation and transmission of nerve
impulses, thereby effecting local anesthesia.
Mepivacaine is rapidly metabolized, with only a small percentage of
the anesthetic (5 to 10 percent)
being excreted unchanged in the urine. Mepivacaine because of its
amide structure, is not detoxified by
the circulating plasma esterases. The liver is the principal site of
metabolism, with over 50 percent of
the administered dose being excreted into the bile as metabolites.
Most of the metabolized Mepivac
