A simple, selective, rapid, and precise reverse phase HPLC method has been developed for the simultaneous estimation of duloxetine HCL in enteric coated capsules. An X Terra RP, C-8 column (4.6x150mm) was used for the separation. The mobile phase was acetonitrile: phosphate buffer (65:35%v/v) (Ph5.3) at a flow rate of 1.0 ml/min with detection at 230nm.
