A Simple UV-Vis Spectrophotometric Assay study on different brands of Mefenamic Acid, Paracetamol and Furosemide

Abstract

The objective of the project seeks to develop an effective significant less going to consume as well as simple spectrophotometry for such assay of Mefenamic acid Paracetamol and Furosemide. Comparative of assay of 3 distinct brand products of Mefenamic acid (Meftal 250-dt, Mefacid, Mefac), Paracetamol (T-98, Parawal-500, Crocin) and Furosemide (Lasix, Frusenex, and Furosemide) available in medical store of Akkalkuwa dist-nandurbar, India has also been done. With us results reveal that between the all 3 brand products anyway of Mefac shows highest percent assay 105.48% while mefacid shows lowest value for percentage assay 95.48% and in all brands of Paracetamol Parawal-500 shows highest percent assay 106.66% T-98 shows lowest percent assay 98.66% & Furosemide Frusenex shows greatest percentage assay of 104% while Furosemide demonstrates lower critical for percentage assay 95%. The part of its success excellent reliability inside the variety of 6.25-100 µg/ml with all brands of Mefenamic acid and Furosemide to correlation coefficient of 0.999. The recovery among all brand products of Mefenamic acid, Paracetamol and Furosemide was > 90%. The dilution and assay method perform in water and NaOH as a solvent.
