Topical pain relievers are mainly some topical patches, including flurbiprofen baboo, fentanyl transdermal patch and so on. If the patient’s pain is not particularly pronounced, that is, relatively mild, he or she can use flurbiprofen baboo for treatment of periarthritis, lumbar disc herniation, lumbar muscle strain and other diseases. The main drug ingredient is flurbiprofen ester, a non-steroidal analgesic and anti-inflammatory drug. If the patient’s pain is very obvious, or even cancerous pain in the late stage of the tumor, with the general analgesic effect is poor, you can consider using fentanyl transdermal patch, used on the surface of the skin, through the slow absorption of drugs, to achieve the analgesic effect.
