A new gradient reverse phase Ultra Performance Liquid Chromatography (UPLC) method was developed for the analysis of Dissolution profile samples of Paricalcitol in Paricalcitol Soft Gelatin capsules. The aim of the new method was to achieve proper accuracy and precision for the highly potent low dose drug product formulations. The normal injection loop allows upto 10µL of the sample in normal condition in UPLC systems.  For the current method the loop was modified to handle 50µL of injection volume in order to achieve quantifiable area counts. Efficient separation is achieved on Acquity UPLC HSS T3 (100 mm length × 2.1 mm ID with, 1.8 m particle size. Validation parameters such as specificity, linearity, precision, accuracy, and robustness were evaluated as per ICH guidelines. The validated RP-UPLC method was successfully applied to the Dissolution of Paricalcitol Soft Gelatin Capsules dosage forms.
