HPLC method for determination of moxifloxacin in plasma and its application in pharmacokinetic analysis

ABSTRACT

Moxifloxacin is a representative of the fourth generation of fluoroquinolones. It possesses bacteriostatic activity against Gram-positive and Gram-negative bacteria. A simple and fast high performance liquid chromatography-ultraviolet detection (HPLC-UV) method was developed for moxifloxacin analysis. The separation was performed on C18 column. The mobile phase was a mixture of acetonitrile and 0.4% triethylamine solution. The regression curve was linear over the range 0.2–10.0 µg/mL. The validation parameters obey the European Medicine Agency limits. The in vivo study confirmed the practical application of the method.
