A simple and specific second-order-derivative spectorophotometric method has been developed and validated for simultaneous quantification of atorvastatin calcium (ATV) and fenofibrate (FEN) in tablet dosage forms. ATV was determined at a wavelength of 281 nm (zero-crossing wavelength point of FEN). Similarly, FEN was measured at 296 nm (zero-crossing wavelength point of ATV) in phosphate buffer, pH 2.8 as solvent. The second derivative amplitude-concentration plots were rectilinear over the range of 2-12 µg/mL for ATV and 1-30 µg/mL for FEN. The % assay in commercial formulation was found to be in the range 98.8 – 102.5 for ATV and 99.6 – 100.25 for FEN by the proposed method. The method was validated as per ICH guidelines. The proposed method can be effectively applied for routine analysis of ATV and FEN in tablets.
