DESCRIPTION

EMLA Cream (lidocaine 2.5% and prilocaine 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. It is also packaged in the Anesthetic Disc, which is a single-dose unit of EMLA contained within an occlusive dressing. The Anesthetic Disc is composed of a laminate backing, an absorbent cellulose disc, and an adhesive tape ring. The disc contains 1 gram of EMLA emulsion, the active contact surface being approximately 10 cm2. The surface area of the entire anesthetic disc is approximately 40 cm2.

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 molecular formula C14H22N2O with a molecular weight of 234.3.

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 molecular formula C13H20N2O with a molecular weight of 220.3.

Each gram of EMLA contains lidocaine 25 mg, prilocaine 25 mg, polyoxyethylene fatty acid esters (as emulsifiers), carboxypolymethylene (as a thickening agent), sodium hydroxide to adjust to a pH approximating 9, and purified water to 1 gram. EMLA contains no preservative, however it passes the USP antimicrobial effectiveness test due to the pH. The specific gravity of EMLA Cream is 1.00.
