A simple precise and economical reverse phase high performance liquid chromatographic method has been developed and validated for the simultaneous estimation of Cilnidipine (CDP), Atenolol (ATL) and Chlorthalidone (CTD).The chromatographic separation was achieved by using Hypersil- keystone C18 (4.6 x 250mm, 5μm) under isocratic conditions The mobile phase consisted of methanol and triple distilled water (80/20, v/v) having pH 7 with a flow rate of 1.0 mL/min. The eluents were monitored at 225 nm for simultaneous measurement.The selected chromatographic conditions were found to effectively separate CDP (Rt: 3.25 min), ATL (Rt: 5.366 min) and CTD (Rt: 9.025 min) having good resolution. The developed method was validated for linearity, accuracy, precision, LOD, LOQ, robustness and for system suitability parameters as per ICH guidelines. In this study, an excellent linearity was obtained with r2 = 0.999, r² = 0.999, r² = 1, for CDP, ATL and CTD respectively. The developed chromatographic method proved to be simple, precise, accurate, robust and reproducible Thus, this method would be employed for routine simultaneous quantification of CDP, ATL and CTD in bulk form or tablet dosage form.   Keywords: Cilnidipine, Atenolol and Chlorthalidone, RP-HPLC.

A simple, accurate, precise high-performance liquid chromatographic (HPLC) method has been developed and validated for the simultaneous determination of abacavir sulphate (ABA) and lamivudine (LAM) in combined dosage form. Separation was performed on a C18 column [Agilent ODS UG 5 column, 250 mm x 4.5 mm], with methanol: water (50:50 V/V) isocratic elution using a flow rate of 1mL/min. Good sensitivity was observed with UV detection at 277 nm. After method development, the interference of other active compounds and excipients, repeatability and linearity, were investigated. Retention times of LAM and ABA were found to be 3.3 and 6.3 min, respectively. The method was validated over the range from 2.5-12.5 μg/mL for LAM and 5-25 μg/mL for ABA with correlation coefficients of 0.9997 and 0.9996, respectively. This method was shown to be accurate, robust, selective, linear, and repeatable and can be successfully employed in routine quality control for the simultaneous analysis of ABA and LAM in tablets.

This paper describes validated reverse phase high-performance liquid chromatographic (RP-HPLC) method for simultaneous estimation of trihexyphenidyl hydrochloride (THP) and risperidone (RSP) in the pure powder form and in combined tablet dosage form. The HPLC separation was achieved on a core shell C18 (100 mm length × 4.6 mm, 2.6 μm particle size) using methanol : ammonium acetate buffer 1% (85 : 15 v/v; pH-6.5) as mobile phase and delivered at flow rate of 0.8 mL/min. The calibration plot showed good linear relationship with r2 = 0.997 ± 0.001 for THP and r2 = 0.998 ± 0.001 for RSP in concentration range of 50–175 μg/mL and 50–175 μg/mL, respectively. LOD and LOQ were found to be 0.40 and 1.29 μg/mL for THP and 1.24 and 3.92 μg/mL for RSP. Assay of THP and RSP was found to be 100.16 ± 0.03% and 99.83 ± 0.02%, respectively. THP and RSP were subjected to different stress conditions (acidic, basic, oxidative, thermal, and photolytic degradation). The degraded product peaks were well resolved from the pure drug peak. The method was successfully validated as per the ICH guidelines. The developed RP-HPLC method was successfully applied for the estimation of THP and RSP in tablet dosage form.
