| Abstract: | Objective To establish a HPLC method for determining the concentration of oxaprozin in human plasma. Methods The proteins were precipitated by adding methanol in the plasma samples. The supernatant was injected directly into the system. The analytical column was Kromasil C18 100 -5 （250 mm ×4.6 mm, 5 μm）, the mobile phase was methanol -0. 166 mol/L NaH2PO4 （80 ： 20,pH =2.22）, the flow rate was 1.0 mL/min, the detection wavelength was 285 nm. Results The linear range of oxaprozin was 0. 25 - 60 μg/mL（ r = 0.999 9）, the inter and intra day RSD were lower than 2.52%. Conclusion The method is simple, rapid, accurate, sensitive and economic. It can be used for studying pharmacokinetics of oxaprozin in human body. |
