Implementation of QbD Approach to the Analytical Method Development and Validation for the Estimation of Propafenone Hydrochloride in Tablet Dosage Form

Abstract

Chromatographic and spectrophotometric methods were developed according to Quality by Design (QbD) approach as per ICH Q8(R2) guidelines for estimation of propafenone hydrochloride in tablet dosage form. QbD approach was carried out by varying various parameters and these variable parameters were designed into Ishikawa diagram. The critical parameters were determined by using principal component analysis as well as by observation. Estimated critical parameters in HPTLC method include solvent methanol, mode of detection absorbance, precoated aluminium backed TLC plate (10 cm 10 cm), wavelength: 250 nm, saturation time: 20 min, band length: 8 mm, solvent front: 70 mm, volume of mobile phase: 5 mL, type of chamber: 10 cm 10 cm, scanning time: 10 min, and mobile phase methanol : ethyl acetate : triethylamine (1.5 : 3.5 : 0.4 v/v/v). Estimated critical parameters in zero order spectrophotometric method were solvent methanol, sample preparation tablet, wavelength: 247.4 nm, slit width: 1.0, scan speed medium, and sampling interval: 0.2, and for first order derivative spectrophotometric method it was scaling factor: 5 and delta lambda 4. The above methods were validated according to ICH Q2(R1) guidelines. Proposed methods can be used for routine analysis of propafenone hydrochloride in tablet dosage form as they were found to be robust and specific.

DEVELOPMENT OF UV SPECTROPHOTOMETRIC METHOD FOR THE DETERMINATION OF BENIDIPINE HYDROCHLORIDE BY USING QUALITY BY DESIGN (QbD) APPROACH

“…Spectral shape, sharpness, and absorbance intensity of spectrum were recorded and compared at varied scan speed such as fast, medium, slow, and very slow and varied sampling interval was such as of 0.1, 0.2, 0.5, 1.0, and 2.0 nm [17]. As shown in fig.…”

Analytical Quality by Design: A Tool for Regulatory Flexibility and Robust Analytics

“…Other method performance characteristics such as linearity and specificity are not needed to be incorporated in the ATP, as they are not directly linked to understand the agreement of a measurement with the true value. For example, an assay ATP should include a statement of accuracy and precision but not necessarily include linearity and specificity [ 31 , 32 ].…”

Standardization of Trigonella foenum-graecum L. Seeds: A Quality by Design Approach

“…QbD approach indicates exploring the quality of analytical process during the development stage itself. 6,7 Trigonella foenum-graceum also is known as Fenugreek or methi belongs to the Fabaceae family, the plant is cultivated in India and North African countries. The seeds of the plant have a long history of usage as potent antidiabetic agent in Ayurvedic and folklore medicine.…”
