@burcinc-- I believe it's still off the market because my aunt orders some from my cousins in France.
I think they should finish up any studies they're doing and release it as soon as possible. It's a good medication, I've heard of many people with chronic pain and sports injuries using it. My aunt has chronic back pain because of a hernia and she has to use a topical muscle relaxant and pain reliever on a regular basis.
Oral ibuprofen has side effects, it causes a lot of stomach problems. This is true for all oral NSAIDs. It's even been shown in studies to be a major cause of ulcers. The good thing about the topical cream is that it absorbs into skin and enters the bloodstream without going through the intestinal tract. So the chances of stomach issues become less likely.
