Abstract
The present invention is related to a trandermal preparation of oxicams. In preparation, it is comprised of 0.1% to 50% of an oxicam, 0.1% to 70% of pure compositions from Chinese herbal enhancers as enhancers, as well as other necessary excipients for transdermal delivery of an active ingredient. This transdermal preparation is intended to be used for anti-inflammatory cases, but with few gastrointestinal side effects. Based on results from testing this preparation on nude mice skin, rabbit skin, and human leg skin, it was found that skin penetration of the transdermal preparation containing 20% terpineol oil was 157.6 times higher than that of the control group.
