Abstract

The invention relates to a drug composition containing loxoprofen sodium and a preparation method of the drug composition. A loxoprofen sodium patch is successively formed by an antisticking film, a drug layer smeared on the antisticking film and a substrate layer covering the drug layer; and the drug layer is prepared from the following components: loxoprofen sodium, a skeleton material, an adhesive, a transdermal enhancers a skeleton material solvent, and the weight ratio of the loxoprofen sodium to the skeleton material is 1 to (1 to 2). When the drug layer is prepared, adhesive cement is homogenized by adopting a homogenizing machine, so that various components are more uniformly dispersed, the uniformity of the drug release speed is guaranteed, and the curative effect is relatively good.

Description

technical field [0001] The invention relates to the technical field of medicine, in particular to a pharmaceutical composition containing loxoprofen sodium and a preparation method thereof. Background technique [0002] Loxoprofen sodium is the first phenylpropionic acid non-steroidal antipyretic analgesic. Loxoprofen sodium is a non-steroidal antipyretic, analgesic, and anti-inflammatory drug developed by Daiichi Sankyo Co., Ltd. for the treatment of rheumatoid arthritis, rheumatoid arthritis, osteoarthritis, and osteoarthritis , low back pain, frozen shoulder, neck and wrist syndrome, and swelling and pain after surgery, trauma and tooth extraction. [0003] Loxoprofen sodium is absorbed rapidly after oral administration, and is distributed in the liver, kidney, and plasma at a higher concentration; thereafter, most of it is the glucuronic acid conjugate of the original substance or the glucuronic acid conjugate of the hydroxylated substance, mainly through Urinary excre...
