Curator's Comment: Description was created based on several sources, including https://www.ncbi.nlm.nih.gov/pubmed/15224555 and https://www.drugs.com/international/urfamycin.html

Thiamphenicol aminoacetate 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. It is used in many countries as a veterinary antibiotic, but is available in China, Morocco and Italy for use in humans. Thiamphenicol aminoacetate is reported as an ingredient of Urfamycin in Ecuador, Indonesia, Italy, Taiwan, Thailand, Turkey, Japan. It is indicated for the treatment of GUT, hepatobiliary, respiratory tract, enteric tract infections, typhoid, paratyphoid fever and salmonellosis, brucellosis.
