A precise and fast novel high-performance liquid chromatography method was developed and validated for the quantitative determination of Famotidine (FMT) in commercially available pharmaceutical dosage forms. An Agilent 1200 Series High Performance Liquid Chromatography (HPLC) system having the column C18 (5µm particle size, 150×4.6 mm) was used in this study and detection (diode array detector) was made at 280 nm. The mobile phase was acetonitrile, distilled water, triethylamine and phosphoric acid (49.9:49.9:0.1:0.1, v/v), isocratic elution under ambient temperature at flow rate of 1.5 mL min-1 with injection volume 5µL. In this method, the retention times for FMT pure, tablets and suspension were 0.787 min, 0.789 min and 0.839 minutes respectively. The new method was validated by different validation parameters. The procedure provided a linear response over the concentration range of 0.1-1.0 mg mL-1 (r2 =0.998) and equation was y=3902.6+18.651. The mean % recovery for inter-day (96.56%) and intra-day (97.36%) assuring a good precision and accuracy was 96-98%. The method was found to be very rapid and the overall assay time was less than 2 minutes and the results obtained were accurate, precise and selective enough to allow the determination of FMT in the presence of certain excipients.
