Abstract

The invention relates to an aerosol with the efficacies of diminishing inflammation and easing pain and a preparation method of the aerosol. The aerosol is composed of a gas phase and a liquid phase, wherein the gas phase is a propellant; the liquid phase is prepared from the following raw materials in parts by weight: 10-20 parts of diclofenac sodium, 5-10 parts of laurocapram, 20-50 parts of propylene glycol, 30-40 parts of alcohol, and 10-20 parts of polyethylene glycol; the weight ratio of the gas phase to the liquid phase is 1: (2-6); the propellant is one or more of dimethylmethane and butane mixture, iso-butane, tetrafluoroethane, heptafluoropropane and dimethyl ether. The aerosol with the efficacies of diminishing inflammation and easing pain provided by the invention has the efficacies of diminishing inflammation and relieving swelling, resolving heat and easing pain, and the like; the test of many clinical research institutions proves that the aerosol provided by the invention has very good treatment effects for sport injuries or the acute attack of acute arthritis such as gout and degenerative arthritis.

Description

technical field [0001] The invention relates to the field of medicine, in particular to an anti-inflammatory and analgesic aerosol and a preparation method thereof. Background technique [0002] Diclofenac sodium is a new type of non-steroidal anti-inflammatory analgesic, which has good antipyretic and analgesic effects. Pain and fever of various causes. [0003] Diclofenac sodium anti-inflammatory and analgesic drugs have the advantages of good curative effect, small side effects, and no accumulation in long-term use among similar drugs. At present, there are many dosage forms of diclofenac sodium on the market, and they have better therapeutic effects. For example, diclofenac sodium oral tablet has better anti-inflammatory and analgesic effects, and diclofenac sodium gel has anti-inflammatory, anti-rheumatic, pain-relieving and antipyretic effects. effect. But these different dosage forms also have various weak points when bringing into play its effect. For example, or...
