Did a search on Ketotifen and found some rather interesting info on a body building message board of all places! Seems those crazy people are using that drug along with the steroids and other junk they take. Unfortunately the poster did not say what these studies were.
"What Is It?
Ketotifen is very safe antihistamine used extensively in Europe to treat bronchial asthma and allergies. It is also being studied as a treatment for colitis. When used for asthma, weight gain and an increase in appetite are among the most frequent side effects. Ketotifen also protects the cells in the stomach, small intestine and perhaps the rest of the gut from a number of toxins. A number of case studies suggest that it may be helpful treating skin problems such as acne. Ketotifen also reduces edema (swelling and puffiness caused by water retention) around sores.
Ketotifen Studies
German researchers have published data showing that ketotifen lowers tnf-alpha in the test tube. One study used ketotifen in combination with oxymethadone, a steroid like Megace that helps people gain weight, so it is hard to gauge what effect ketotifen had (the study notes a 14% reduction in TNF-alpha levels and weight gains of 11-12 pounds in less than four weeks). A larger placebo controlled study of this combination is underway. The other study used ketotifen by itself in eight patients with elevated TNF-alpha, (but no wasting). Taking ketotifen for 12 weeks, these patients gained an average of six pounds, had increases in their body cell mass and reductions in their TNF-alpha levels. "
I found the part about TNF-alpha levels interesting since some of us are thought to have too much of it. Wish I knew what these studies were though.
