Overview

Rifamycin is the prime member of the rifamycin family which are represented by drugs that are a product of fermentation from the gram-positive bacterium Amycolatopsis mediterranei, also known as Streptomyces mediterranei. The parent compound of rifamycin was rifamycin B which was originally obtained as a main product in the presence of diethylbarburitic acid. Some small modifications where performed in this inactive compound and with the creation of rifamycin SV there was the first antibiotic used intravenously for the treatment of tuberculosis. Rifamycin has had several direct derivative products such as rifamycin SV, rifaximin, rifampin and rifamycin CV. All of the derivatives have slight different physicochemical properties when compared to the parent structure. Rifamycin was further developed by Cosmo Technologies Ltd and approved in November 16, 2018 by the FDA as a prescription drug after being granted the designation of Qualified Infectious Disease Product which allowed it to have a status a priority review. This drug was also sent for review to the EMA in 2015 by Dr. Falk Pharma Gmbh and it was granted a waiver for the tested conditions.

Indication

Rifamycin is indicated for the treatment of adult patients with travelers' diarrhea caused by noninvasive strains of E. coli. The status of the disease should not be complicated by fever or blood in the stool. To prevent drug-resistant bacteria, it is important to mention that the use of rifamycin for this indication should be only done in cases where the infection is proven or strongly suspected to be caused by bacteria. Travallers' diarrhea is very common problem affecting 20-60% of the travellers and it is defined as an increase in frequency of bowel movements to three or more loose stools per day during a trip abroad. This condition is rarely life threatening but in severe cases it can produce dehydration and sepsis. The most common cause of travellers' diarrhea is a pathogen and from the pathogens identified, bacteria is the most common cause followed by norovirus, rotavirus and similar viruses.

Associated Conditions

  • Not complicated by fever, not complicated by bloody stool Traveler's Diarrhea caused by noninvasive strains of Escherichia coli
