In August 2020, the U.S. Food and Drug Administration (FDA) became aware of nitrosamine impurities in certain samples of rifampin. [61] The FDA and manufacturers are investigating the origin of these impurities in rifampin, and the agency is developing testing methods for regulators and industry to detect the 1-methyl-4-nitrosopiperazine (MNP ...

Isoniazid/rifampicin, also known as isoniazid/rifampin, is a medication used to treat tuberculosis. [1] It is a fixed dose combination of isoniazid and rifampicin (rifampin). [1] It is used together with other antituberculosis medication. [1] It is taken by mouth. [1] It is on the World Health Organization's List of Essential Medicines. [2]
Rifampin rapidly kills fast-dividing bacilli strains as well as "persisters" cells, which remain biologically inactive for long periods of time that allow them to evade antibiotic activity. [7] In addition, rifabutin and rifapentine have both been used against tuberculosis acquired in HIV-positive patients.
These may include poor coordination, loss of appetite, nausea, joint pain, feeling tired, and numbness. [2] Severe side effects include liver problems. [3] Use in those under the age of 15 may not be appropriate. [3] It is unclear if use in pregnancy is safe for the baby. [3]
In non-resistant TB, rifampin binds the beta subunit of RNA polymerase and disrupts transcription elongation. Mutation in the rpoB gene changes the sequence of amino acids and eventual conformation, or arrangement, of the beta subunit. In this case, rifampin can no longer bind or prevent transcription, and the bacterium is resistant. [19] [20]
Pyridoxine may be used to decrease the risk of numbness. [2] It is not recommended in people with liver problems or severe kidney problems. [3] Use may not be suitable in children. [1] It is unclear if use during pregnancy is safe. [3] It is on the World Health Organization's List of Essential Medicines. [4]
