Ārstēšanas norādes:

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 [e.g., RIFATER® ]1 is recommended in the initial phase of short-course therapy which is usually continued for 2 months.

CLINICAL PHARMACOLOGY
INTRAVENOUS ADMINISTRATION
After intravenous administration of a 300 or 600 mg dose of rifampin
infused over 30
minutes to healthy male volunteers (n=12), mean peak plasma
concentrations were 9.0
± 3.0 and 17.5 ± 5.0 mcg/mL, respectively. Total body clearances
after the 300 and 600
mg IV doses were 0.19 ± 0.06 and 0.14 ± 0.03 L/hr/kg, respectively.
Volumes of

distribution at steady state were 0.66 ± 0.14 and 0.64 ± 0.11 L/kg
for the 300 and 600
mg IV doses, respectively. After intravenous administration of 300 or
600 mg doses,
rifampin plasma concentrations in these volunteers remained detectable
for 8 and 12
hours, respectively (see Table).
