Abstract

The invention relates to local externally-applied antalgic compound preparation composition for skin and a preparation method of the compound preparation composition. The compound preparation composition comprises the following components: (a) lidocaine hydrochloride; (b) ropivacaine hydrochloride monohydrate and conventional pharmaceutic adjuvant. The invention further relates to the preparation method of the compound preparation composition, which comprises the following steps of: mixing the lidocaine hydrochloride and the ropivacaine hydrochloride monohydrate through a conventional technological way and the conventional pharmaceutic adjuvant, and carrying out split charging to obtain the compound preparation composition. According to the compound preparation composition and the preparation method, the effect is significant, the efficacy time is long, the side effect is reduced, and the compliance of the patients is improved, so that the pain of the patients is alleviated. The compound preparation method composition provided by the invention can be applied to the pains caused by various factors, and has a good application prospect.

Description

technical field [0001] The invention relates to the technical field of medicine, in particular to a skin topical analgesic compound preparation composition and a preparation method thereof. Background technique [0002] Local pain is the most common postoperative or posttraumatic pain in the clinic, mainly including skin wound pain, local pain caused by injection or puncture, and postherpetic neuropathic pain. Due to the large workload of clinical nursing, the pain brought by local pain to patients has not attracted the attention of the majority of medical staff. The use of local anesthetic percutaneous administration to treat local pain has achieved good clinical results, such as the use of compound lidocaine cream (Enna cream, Emlacream, each gram of cream contains 25 mg of prilocaine and lidocaine) , stabilize the nerve cells by blocking the ion flow required for the generation and conduction of nerve impulses, thereby producing a local anesthetic effect to achieve local...
