Also Known As: Lidocaine/prilocaine, Emla
Lidocaine/prilocaine is a eutectic mixture of equal quantities (by weight) of lidocaine and prilocaine. A 5% emulsion preparation, containing 2.5% each of lidocaine/prilocaine, is marketed by APP Pharmaceuticals under the trade name EMLA (an abbreviation for Eutectic Mixture of Local Anesthetics).
The lidocaine/prilocaine combination is indicated for dermal anaesthesia. Specifically it is applied to prevent pain associated with intravenous catheter insertion, blood sampling, superficial surgical procedures; and topical anaesthesia of leg ulcers for cleansing or debridement. Also, it can be used to numb the skin before tattooing as well as electrolysis and laser hair removal.
Researchers have shown that a new topical spray, consisting of an aerosol formulation of lidocaine and prilocaine, applied on the penile skin five minutes prior to intercourse is effective for treating premature ejaculation without adversely affecting the sensation of ejaculation.
