11 DESCRIPTION
CARBOCAINE contains mepivacaine hydrochloride, an amide local anesthetic, as the active pharmaceutical ingredient. The route of administration for CARBOCAINE is by injection, for local infiltration, peripheral nerve block, and caudal and lumbar epidural blocks. Multiple-dose vials contain methylparaben [see Warnings and Precautions (5.3)].
Mepivacaine hydrochloride is 2-piperidinecarboxamide, N-(2,6-dimethylphenyl)-1-methyl, monohydrochloride. It is a white crystalline odorless powder, soluble in water, but very resistant to both acid and alkaline hydrolysis. It has the following structural formula:
C15H22N2O • HCl
CARBOCAINE (mepivacaine hydrochloride) is a clear and colorless sterile isotonic solution.
