The rifamycin group includes the classic rifamycin drugs as well as the rifamycin derivatives rifampicin (or rifampin), rifabutin, rifapentine, rifalazil and rifaximin. Rifamycin, sold under the trade name Aemcolo, is approved in the United States for treatment of travelers' diarrhea in some circumstances. [1] [2] [3]
Rifampicin is of the rifamycin group of antibiotics. [3] It works by decreasing the production of RNA by bacteria. [3] Rifampicin was discovered in 1965, marketed in Italy in 1968, and approved in the United States in 1971. [5] [6] [7] It is on the World Health Organization's List of Essential Medicines. [8]
Rifaximin is a semisynthetic broad spectrum antibacterial drug, derived through chemical modification of the natural antibiotic rifamycin. [29] It has very low bioavailability due to its poor absorption after oral administration.
For Mycobacterium tuberculosis, the rifamycin-resistant mutations most commonly encountered involve codons 516, 526, and 531 (numbered, by convention, as in Escherichia coli rpoB). [ 11 ] [ 12 ] These mutations result in high rifampicin resistance with a relatively low loss of fitness. [ 8 ]
It produces the rifamycin antibiotics (e.g., rifamycin SV), which are used to treat mycobacterial diseases such as tuberculosis and leprosy. [2] The type strain of Amycolatopsis rifamycinica (DSM 46095) has been reclassified several times. When it was first isolated from a French soil sample in 1957, it was identified as Streptomyces ...
The main result was a relative risk (RR) of 0.40 (95% confidence interval (CI) 0.31 to 0.52) for development of active tuberculosis over two years or longer for patients treated with INH, with no significant difference between treatment courses of six or 12 months (RR 0.44, 95% CI 0.27 to 0.73 for six months, and 0.38, 95% CI 0.28 to 0.50 for ...
