 Lidocaine 2.5 and Prilocaine 2.5 Cream, is an emulsion in which the oil phase is a eutectic mixture of Lidocaine and Prilocaine cream 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 liquid oil rather than as crystals. Its absorption of from the genital mucosa is more rapid and onset time is shorter 5 to 10 minutes than after application to intact skin. After a 5 to 10 minute application of Lidocaine-Prilocaine cream to female genital mucosa, the average duration of effective analgesia was 15 to 20 minutes.
