Application

Rifapentine is an antibiotic clinically used to treat tuberculosis. It is used in tuberculosis research.

Biochem/physiol Actions

Rifapentine is a semisynthetic derivative of rifampicin with antibacterial activity against Gram-positive and Gram-negative bacteria and against Mycobacterium tuberculosis. Rifapentine inhibits DNA-dependant RNA polymerase and prevents RNA transcription. It interacts with bacterial RNA polymerase but does not inhibit the mammalian enzyme.

Preventive therapy is essential for reducing tuberculosis (TB) burden among people living with HIV (PLWH) in high-burden settings. Short-course preventive therapy regimens, such as three-month weekly rifapentine and isoniazid (3HP) and one-month daily rifapentine and isoniazid (1HP), may help facilitate uptake

Targeting biofilm-embedded and intraosteoblastic Staphylococcus aureus, rifampicin gained a pivotal role in bone and joint infection (BJI) treatment. Two other rifamycins, rifabutin and rifapentine, may represent better-tolerated alternatives, but their activity against bacterial reservoirs associated with BJI chronicity has never
