Dimethyl sulphoxide, or DMSO, was the first nonsteroidal anti-inflammatory discovered since aspirin. DMSO reduces inflammation by several mechanisms. It is an antioxidant, a scavenger of the free radicals that gather at the site of injury. Studies have shown DMSO helps relieve the pain in inflammatory conditions, including rheumatoid arthitis, and that DMSO is of major benefit in scleroderma, as it has softening effect on collagen. DMSO has wide application range in the manufacture of pharmaceuticals, as it quickly penetrates the skin, thus facilitating the absorbption of other topical therapeutic agents. DMSO for human therapeutic use was recently made a prescription only medicine in NSW. Please e-mail or fax your prescription to us prior ordering.
