Assay Of Lamotrigine And Nicorandil By Difference Spectroscopy
Two analytical methods for the estimation of lamotrigine and nicorandil in bulk drug and in their tablet formulations are described. These methods are based upon difference spectroscopy and are quite, simple, rapid, sensitive and selective. The Beer's law range was followed in the concentration range of 5-35 Î¼g/ml and 10-40 Î¼g/ml. The molar absorptivities were 9.731x103 I/mol.cm and 2.407x103 I/mol.cm for lamotrigine and nicorandil respectively.
