WebRifamycins are broad-spectrum antibiotics and the first-line of drugs, which are used for the treatment of infections with Mycobacterium tuberculosis and in combinational therapies with other drugs. This is because they are capable of inducing cell death in mycobacteria species, although resistance can rapidly be developed. WebRifampin also induces Phase II metabolizing enzymes, which are responsible for biotransformations such as glucuronidation and sulfation, as well as the efflux pump p-glycoprotein and other drug transporters. Induction of these enzymes can lead to reduced plasma concentrations of co-administered drugs that are substrates of these enzymes.
