Rifampin is a prescription medication used for treatment of both tuberculosis and the meningococcal carrier state. Bacteriologic cultures should be obtained before the start of therapy to confirm the susceptibility of the organism to rifampin and they should be repeated throughout therapy to monitor the response to treatment.
What is the drug rifampin used to treat?
Rifampin is indicated for the treatment of asymptomatic carriers of Neisseria meningitidis to eliminate meningococci from the nasopharynx. Rifampin is not indicated for the treatment of meningococcal infection because of the possibility of the rapid emergence of resistant organisms.(See WARNINGS.)

With multidrug therapy used as the standard treatment of Hansen's disease, rifampicin is always used in combination with dapsone and clofazimine to avoid causing drug resistance.
How does rifampicin work?
It works by decreasing the production of RNA by bacteria. Rifampicin was discovered in 1965, marketed in Italy in 1968, and approved in the United States in 1971. It is on the World Health Organization's List of Essential Medicines.
How much of rifampicin is excreted in urine?
Only about 7% of the administered drug is excreted unchanged in urine, though urinary elimination accounts for only about 30% of the drug excretion. About 60% to 65% is excreted through feces. The half-life of rifampicin ranges from 1.5 to 5.0 hours, though hepatic impairment significantly increases it.
What is the mechanism of action of rifampicin?
Mechanism of action. Binding of rifampicin in the active site of RNA polymerase. Mutation of amino acids shown in red are involved in resistance to the antibiotic. Rifampicin inhibits bacterial DNA-dependent RNA synthesis by inhibiting bacterial DNA-dependent RNA polymerase.
How long does rifampicin last?
For the treatment of tuberculosis, it is administered daily for at least six months. Combination therapy is used to prevent the development of resistance and to shorten the length of treatment.
Where are rifampicin mutations in rpob?
When describing mutations in rpoB in other species, the corresponding amino acid number in E. coli is usually used. In Mycobacterium tuberculosis, the majority of mutations leading to rifampicin resistance are in cluster I, in a 81bp hotspot core region called RRDR for "rifampcin resistance determining region".
What are the side effects of rifampicin?
The more common side effects include fever, gastrointestinal disturbances, rashes, and immunological reactions. Taking rifampicin usually causes certain bodily fluids, such as urine, sweat, and tears, to become orange-red in color, a benign side effect that nonetheless can be frightening if it is not expected.
