The HPLC method was established for the detection of doxazosin Mesylate sustained - release capsules. The C18 silica gel column was used and the mobile phase was consisted of methano:water:glacial acetic acid:diethylamine (700:300:10:2) o The detection wavelength was 249nm and flow rate 1.0 ml ·min^ - 1. A good linearity was obtained of 30.67 - 71.57μg · ml^ - 1. The average recovery was 99.38% and the RSD was 0.83% o This method is simple,rapid,accurate and suitable for the determination DOX sustained - release capsules .
