Abstract
A device for treating antifungal infections of toenails and fingernails is made up of an occlusive backing layer and a pressure sensitive adhesive matrix layer in which is uniformly dispersed an effective amount of an antifungal agent and, optionally, a chemical enhancer. The matrix layer has a first surface adhering to the backing layer and a second surface adapted to be in diffusional contact with the infected nail and surrounding skin area. The device is configured, when applied, to cover and adhere to the nail and surrounding skin areas for an extended period of time without causing irritation to the skin or inhibiting normal physical activity while providing a continuous delivery of antifungal agent to the infected area.
