My mother brought back a few boxes of this stuff called Mark-Fast frm Egypt. It contains 200mg clozoxazone & 200mg ibuprofen. I looked on the search engine and theres nothing I found very helpful. Id like to know how these work so well, it seems much more potent than soma and is potentiating my hydrocodone almost too much like phenobarbital and suboxone. Does anyone have experiences with chlorzoxazone and other things it may potentiate more than one would think and any info on what it works on in the body. The wiki article is only like a paragraph
