Abstract
A composition and its use for local percutaneous delivery of a drug, in particular a muscle relaxant, more particularly cyclobenzaprine present in an amount of about 1 to about 10% by weight of the composition in an organogel cream are disclosed. The composition is applied directly to the skin over accessible muscles of mastication from which it is rapidly absorbed through the skin to provide control of conditions such as bruxism and tooth clenching. The composition can also be applied to the skin overlying these muscles to control muscle hyperactivity (spasm) and/or trigger points, from other causes. The composition can be formulated to include another active agent such as a non-steroidal anti-inflammatory, for example ketoprofen.
