Abstract

A compound analgesic for bone fracture, injury, ecchymoma, nerval pain, etc is composed of antisticking layer, hydrophilic gel layer and substrate layer. Said hydrophilic gel layer consists of the medicine prepared from lidocaine hydrochloride and superfine notoginseng powder or its extract and the matrix prepared from gelatin, carboxymethyl cellulose sodium, polyvinyl pyrrolidone, etc.

Description

Technical field: [0001] The invention relates to the technical field of medicine, and relates to an analgesic cataplasm prepared from a compound prescription of lidocaine hydrochloride and notoginseng. Background technique: [0002] Lidocaine hydrochloride is a commonly used amide-type medium-effect local anesthetic in clinical practice. It has the advantages of fast and strong local anesthetic effect, strong penetrating power and long effect, and is considered to be an ideal local anesthetic. At present, the 5% lidocaine patch for skin administration has been approved to go on the market (trade name LIDODERM) abroad.  ), has the characteristics of low systemic blood drug concentration, drug concentration at the site of administration, and less systemic adverse reactions. It is widely used for pain relief of peripheral neuralgia, especially post-herpetic neuropathic pain. There are also some domestic research reports on the transdermal absorption of lidocaine [Cheng Yuhui ...
