Rifapentine-HongQi Pharm is an antibiotic that inhibits DNA-dependent RNA polymerase activity in susceptible cells. Specifically, it interacts with bacterial RNA polymerase but does not inhibit the mammalian enzyme. It is bactericidal and has a very broad spectrum of activity against most gram-positive and gram-negative organisms (including Pseudomonas aeruginosa) and specifically Mycobacterium tuberculosis. Because of rapid emergence of resistant bacteria, use is restricted to treatment of mycobacterial infections and a few other indications. Rifampin is well absorbed when taken orally and is distributed widely in body tissues and fluids, including the CSF. It is metabolized in the liver and eliminated in bile and, to a much lesser extent, in urine, but dose adjustments are unnecessary with renal insufficiency.

Rifapentine-HongQi Pharm is also used to associated treatment for these conditions: Active Tuberculosis, Late phase Tuberculosis

How Rifapentine-HongQi Pharm works

Rifapentine-HongQi Pharm has shown higher bacteriostatic and bactericidal activities especially against intracellular bacteria growing in human monocyte-derived macrophages. Rifapentine-HongQi Pharm inhibits DNA-dependent RNA polymerase in susceptible strains of M. tuberculosis. Rifapentine-HongQi Pharm acts via the inhibition of DNA-dependent RNA polymerase, leading to a suppression of RNA synthesis and cell death.

Food Interaction

Take with food. Taking rifapentine with food increases its bioavailability and reduces gastrointestinal upset. Rifapentine-HongQi Pharm tablets can be crushed and mixed with semisolid food if necessary.

Rifapentine-HongQi Pharm Drug Interaction
