ABSTRACT:
Xerogel films on substrates are provided containing pharmaceutically active compounds. Articles incorporating such films are robust, release active compounds at predictable rates and may provide such release for relatively long periods of time. Orthopedic and trauma uses are indicated along with generalized use in contact with body fluids or as biological implants. Methods for fabrication of such films and devices are provided.
