Abstract

The invention relates to an ibuprofen liquid injection which is characterized by comprising active ingredient ibuprofen and cosolvent arginine at molar ratio of 1:1-1:1.2, and adopting ammonia water and hydrochloric acid as pH regulator. Ammonia water is added into solution of ibuprofen and arginine to regulate pH value to 7.8-9.0, to obviously reduce insoluble particles, and solve compatibility problem between the liquid injection and sodium chloride and glucose liquid injection; then hydrochloric acid is adopted to regulate pH value back to 7.0-8.0, to enable solution pH value to be same asor approximate to human body blood pH value, and improve administration compliance and comfort of patient.

Description

technical field [0001] The invention belongs to the field of pharmaceutical preparations, and relates to an ibuprofen injection composition and a preparation method thereof. Background technique [0002] Ibuprofen is a non-steroidal anti-inflammatory analgesic with the following structural formula, which has anti-inflammatory, analgesic and antipyretic effects. [0003] [0004] α-Methyl-4-(2-methylpropyl)phenylacetic acid [0005] Ibuprofen is a classic antipyretic and analgesic drug, which can inhibit the synthesis of prostaglandins and has analgesic and antipyretic effects. [0006] Ibuprofen is a classic antipyretic and analgesic drug, which can inhibit the synthesis of prostaglandins and has analgesic, antipyretic and anti-inflammatory effects.
