Rifampin and two of its major metabolites, 25-O-desacetylrifampin and 3-formylrifamycin SV, were quantitated in serum, urine, and aqueous solutions by high-pressure, reverse-phase liquid chromatography. This rapid, precise, and simple method utilizes a single-step extraction, dual-wavelength monitoring, and quantitation by comparison of the absorbance of the drug or metabolite with that of an internal standard; the wavelengths used are 337 nm and 254 nm. The degrees of precision are +/- 1.3… CONTINUE READING
