Determination and Validation of HPTLC Method for Cinacalcet Hydrochloride

Authors:Swetha Kamatham, Ciddi Veeresham

ABSTRACT
Cinacalcet Hydrochloride (CIN) is a new calcimimetic agent indicated for the use in hypercalcemia. The present work is aimed at development and validation of a novel and simple high-performance thin-layer chromatographic (HPTLC) method for the analysis of Cinacalcet Hydrochloride (active pharmaceutical ingredient, API. In the method, Aluminum-backed silica gel 60 F254 plates (10 × 10 cm) were used as stationary phase and chloroform: acetonitrile (6:4, v/v) as the mobile phase, which showed compact bands of Cinacalcet HCl (RF 0.30 ± 0.02). Quantitative analysis was carried out by densitometry at a wavelength of 282 nm. Linear regression analysis for the calibration spots showed good correlation ship with regression co-efficient r2 = 0.9994 in the range of 40 – 160 ng/band. The developed method suitability for quantification of CIN was learned by validating it as per the ICH guidelines. CIN detection limit was 0.48 ng/band and the quantification limit was 1.59 ng/band. The proposed method was found to be linear (r2 = 0.999), precise (%RSD < 2% for intraday and intermediate precision), accurate, specific, and robust. Further, the developed method was validated and found suitable for stress induced studies, since presence of degradants has no effect on CIN estimation. The proposed method was found to be simple, sensitive, precise, accurate and reproducible for the estimation of CIN.
