Abstract Background Dronedarone HCl is an anti-arrhythmic drug indicated for atrial fibrillation. Dronedarone HCl(DRN) has a low solubility of 2 µg/mL and 4% bioavailability, thus it is formulated as co-amorphous system to enhance its solubility by using Quercetin(QCT) as coformer. Literature lacks a sensitive, accurate and economic method for simultaneous quantification of DRN and QCT in formulation. Objective To develop a RP-HPLC method for simultaneous estimation of DRN and QCT in DRN-QCT co-amorphous system. Method Co-amorphous system was prepared using solvent evaporation technique using DRN and QCT in 1:1 molar ratio. The separation was achieved on Purospher® STAR C18 (250 mm × 4.6 mm × 5 μm) column with mobile phase comprising of Acetonitrile and 25 mM phosphate buffer pH 3.6 (60:40, % v/v). Results DRN and QCT retained at 6.7 and 3.5 min, respectively. For both molecules, method was developed with a wide linearity range of 0.2–500 µg/mL. LOD for DRN was found to be 0.0013 and 0.0026 µg/mL for QCT. Also, LOQ for DRN was found to be 0.0041 and 0.0078 µg/mL for QCT. Conclusion Method was validated as per ICHQ2R1 guidelines for linearity, precision, accuracy, and robustness. The method was used in simultaneous quantification of DRN and QCT in co-amorphous samples. Highlights The method developed was used for the analysis of content uniformity and solubility samples of co-amorphous system, where the method was able to successfully quantify DRN and QCT. Low detection and quantification limits contribute to sensitivity of the method and wide linearity range assures the robust and precise quantification of molecules.

Background: It has been hypothesized that delivery of aripiprazole through nanoemulsion formulation would better deliver the drug into the central nervous system to treat major depressive conditions in psychological patients. Due course of formulation development, to determine solubility of the drug in different matrices and nanoemulsion is an important step. Materials & Methods: Therefore, a simple, rapid and selective reversed phase high performance liquid chromatographic (RP-HPLC) method was developed and validated for the determination of aripiprazole as per International Conference of Harmonization (ICH) guidelines. Satisfactory analysis method was employed for the quantitative determination of aripiprazole during pre-formulation development. Results and Discussion: The separation technique was achieved using the mobile phases of methanol-acetonitrile, 80:20 (v/v) delivered at 1.0 mL.min-1 flow rate through HIQ SIL C18 250x4.6 mm (5 μm particle size) column and detected at 218 nm wavelength. The method depicted linear calibration plots within the range of 5 to 50 µg.mL-1 with a determination coefficient (r2) of 0.9991 calculated by least square regression method. The validated method was sensitive with LOD of 10.0 ng.mL-1 and 30.0 ng.mL-1 of LOQ. The intra-day and inter-day precision values were ranged between 0.37-0.89 and 0.63-1.11 respectively, with accuracy ranging from 98.24 to 100.88 and 97.03 to 100.88, respectively. This developed and validated method was found to be sensitive for the determination of aripiprazole for the first time from various oils, surfactants, co-surfactants, and nanoemulsion formulation. Conclusion: This RP-HPLC method was successfully implemented for the quantitative determination of aripiprazole at developmental stages of nanoemulsion formulation.
