Codeine is a narcotic pain-reliever and cough suppressant similar to morphine and hydrocodone. Moreover, a small amount of codeine is converted to morphine in the body. The precise mechanism of action of codeine is not known; however, like morphine, codeine binds to receptors in the brain (opioid receptors) that are important for transmitting the sensation of pain throughout the body and brain. Codeine increases tolerance to pain, decreasing discomfort, but the pain still is apparent to the patient.
âA topical preparation of a skin lightening composition containing MSM in an amount of approximately 1 to 25 weight percent, such as about 15%, or greater than 20% by weight, is applied to a personâs skin in a daily regimen.
MSM (methyl sulfonyl methane) is a sulfur-containing compound normally found in many of the foods we eat. It is chemically related to DMSO (dimethyl sulfoxide), a popular (although unproven) treatment for arthritis.When DMSO is applied on the skin or taken orally, about 15% of it breaks down in the body to form MSM. 1.SM (methyl sulfonyl methane) is a sulfur-containing compound normally found in many of the foods we eat.
