LIDOCAINE 2.5% AND PRILOCAINE 2.5% CREAM
FOR TOPICAL USE ONLY. NOT FOR OPHTHALMIC USE.
DESCRIPTION
Lidocaine 2.5% and Prilocaine 2.5%, a topical anesthetic agent, 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 15 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 2.5% and prilocaine 2.5% cream contains
lidocaine 25 mg, prilocaine 25 mg,
carboxypolymethylene (as a thickening agent), polyoxyethylene fatty
acid esters (as emulsifiers),
purified water to 1 gram, and sodium hydroxide to adjust pH (pH range
9.0-9.4). Lidocaine 2.5% and
prilocaine 2.5% cream contains no preservative, however it passes the
USP antimicrobial effectiveness
test due to the pH. The specific gravity of lidocaine 2.5% and
prilocaine 2.5% cream is 1.00.
CLINICAL PHARMACOLOGY
MECHANISM OF ACTION:
Lidocaine 2.5% and prilocaine 2.5% cream, applied to intact skin under
occlusive dressing, 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.
