DESCRIPTION
Lidocaine and prilocaine cream USP, 2.5%/2.5% is an emulsion in which
the oil phase is a eutectic
mixture of lidocaine and prilocaine in a ratio of 1:1 by weight. This
eutectic mixture has a melting point
below room temperature and therefore both local anesthetics exist as a
liquid oil rather than as crystals.
It is packaged in 5 gram and 30 gram tubes.
Lidocaine is chemically designated as acetamide,
2-(diethylamino)-N-(2,6-dimethylphenyl), has an
octanol: water partition ratio of 43 at pH 7.4, and has the following
structure:
Prilocaine is chemically designated as propanamide,
N-(2-methylphenyl)-2-(propylamino), has an
octanol: water partition ratio of 25 at pH 7.4, and has the following
structure:
Each gram of lidocaine and prilocaine cream contains lidocaine 25 mg,
prilocaine 25 mg, purified
water, PEG-60/hydrogenated castor oil, carbopol 5984 and sodium
hydroxide to adjust pH to
approximately 9. Lidocaine and prilocaine cream contains no
preservative, however it passes the USP
antimicrobial effectiveness test due to the pH. The specific gravity
of lidocaine and prilocaine cream is
1.00.
The therapeutic class is topical anesthetic agent.

provides dermal analgesia by the release of lidocaine and prilocaine
from the cream into the epidermal
and dermal layers of the skin and by the accumulation of lidocaine and
prilocaine in the vicinity of
dermal pain receptors and nerve endings. Lidocaine and prilocaine are
amide-type local anesthetic
agents. Both lidocaine and prilocaine stabilize neuronal membranes by
inhibiting the ionic fluxes
required for the initiation and conduction of impulses, thereby
effecting local anesthetic action.
