The efficacy and function of Debaining Lidocaine Gel Plaster?

Debaining lidocaine gel plaster can be used to relieve the pain of patients with postherpetic neuralgia. Post-herpetic neuralgia is characterized by hyperalgesia, which can produce severe and unbearable pain with light touch. The plaster can directly act on the painful part, so that patients can get rid of the pain anytime and anywhere, avoid the first-pass effect of the liver, and have less gastrointestinal absorption, and the curative effect is not affected by the patient's age, health status, digestive ability and other factors? If oral or local medication is not effective for patients, lidocaine external patch can be combined with oral medication to further relieve pain. For elderly patients in particular, it can improve the analgesic effect and reduce the adverse reactions of other drugs. Besides neuralgia after herpes zoster, the plaster can also be used for peripheral neuropathic pain such as diabetic peripheral neuropathy, trigeminal neuralgia and postoperative neuralgia.
