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
