Description

technical field [0001] The invention belongs to the technical field of medicine, and in particular relates to an ibuprofen suspension and a preparation method thereof. Background technique [0002] Ibuprofen, also known as ibuprofen, has anti-inflammatory, analgesic and antipyretic effects. Ibuprofen is suitable for the treatment of rheumatoid arthritis, rheumatoid arthritis, osteoarthritis, ankylosing spondylitis and neuritis. [0003] Since the advent of ibuprofen, it has been favored by consumers because of its anti-inflammatory, pain-relieving and antipyretic effects, which are far superior to aspirin, phenylbutazone and paracetamol. After widely entering the family, ibuprofen has made a huge contribution to relieving the head and body pain caused by patients' joint pain, neuralgia, dysmenorrhea and other diseases. According to the usage data of ibuprofen, the sales volume of ibuprofen is about double that of similar antipyretic and analgesic drugs. [0004] At presen...
