    摘要: A composition and method to alleviate oral mucosal discomfort and irritation in an orthodontic patient. A wax matrix containing less that 15% analgesic/anesthetic agent such as benzocaine and excipients enhanced and extended release of the analgesic/anesthetic agent compared to known art formulations. The composition exhibited desirable aesthetic properties, was easy to apply, and the relatively lower concentration of active agent provided enhanced safety.

    摘要: The present invention provides, inter alia, formulations useful to ameliorate symptoms associated with mucosal abrasions, specifically those due to dental orthodontic brackets; oral surgery; periodontal surgery or other procedures. For instance, there is a formulation comprising: 65 to 75% microcrystalline wax; 5 to 15% non-ionic polymer; 15 to 25% topical anesthetic; and 1 to 5% surfactant, wherein the ratio of non-ionic polymer to microcrystalline wax is no greater than 0.2. Preferably, for solid topical anesthetics, the particle size is less than the apertures of a 100-mesh screen. However, the topical anesthetic may also be a liquid. Formulations wherein the mixture is a homogeneous matrix is preferred.
