適応症:

In the treatment of both tuberculosis and the meningococcal carrier state, the small number of resistant cells present within large populations of susceptible cells can rapidly become the predominant type. 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. Since resistance can emerge rapidly, susceptibility tests should be performed in the event of persistent positive cultures during the course of treatment. If test results show resistance to rifampin and the patient is not responding to therapy, the drug regimen should be modified. Rifampin is indicated in the treatment of all forms of tuberculosis. A three-drug regimen consisting of rifampin, isoniazid, and pyrazinamide (eg, RIFATER® 1) is recommended in the initial phase of short-course therapy which is usually continued for 2 months.

and pediatric populations vary widely from individual to individual.
Following a single 600 mg oral
dose of rifampin in healthy adults, the peak serum concentration
averages 7 mcg/mL but may vary from 4
to 32 mcg/mL. Absorption of rifampin is reduced by about 30% when the
drug is ingested with food.
Rifampin is widely distributed throughout the body. It is present in
effective concentrations in many
organs and body fluids, including cerebrospinal fluid. Rifampin is
about 80% protein bound. Most of
