<unk>  (also known as thiophenicol and dextrosulphenidol) is an antibiotic. It is the methyl-sulfonyl analogue of chloramphenicol and has a similar spectrum of activity, but is 2.5 to 5 times as potent.  Like chloramphenicol, it is insoluble in water, but highly soluble in lipids.  It is used in many countries as a veterinary antibiotic, but is available in China, Morocco and Italy for use in humans.  Its main advantage over chloramphenicol is that it has never been associated with aplastic anaemia.<unk>  is also widely used in Brazil, particularly for the treatment of sexually transmitted infections and pelvic inflammatory disease.
Unlike chloramphenicol,<unk>  is not readily metabolized in cattle, poultry, sheep, or humans, but is predominantly excreted unchanged. In pigs and rats the drug is excreted both as parent drug and as<unk>  glucuronate (FAO, 1997).
