| Title: | Solid-forming topical formulations for pain control |
| Abstract: | Methods of applying a solid forming local anesthetic formulations can include applying a layer of a solid-forming formulation to a skin surface, wherein the solid-forming local anesthetic formulation includes from 4 wt % to 30 wt % of a local anesthetic, less than 36 wt % dicalcium phosphate, water, and a polymer. These methods can further include maintaining the layer of the formulation on the skin surface for a period of time sufficient to allow the layer of the formulation to transition from a semi-solid to a cohesive film and to topically deliver the local anesthetic to the skin surface, and removing the layer of the formulation from the skin surface by peeling the layer of the formulation off the skin surface. The layer of the formulation can be operable to be removed as a single piece or two to three large pieces. |
