RAPID AND SIMPLE SPECTROPHOTOMETRIC METHOD  FOR THE DETERMINATION OF ANTIVIRAL  AND ANTI-PARKINSONISM DRUGS
A rapid and sensitive spectrophotometric method has been developed for the quantitative analysis of three antiviral, anti-parkinsonism drugs, namely amantadine (AMA), memantine (MET), and rimantadine (RIM). The method is based on the usage of 1,3-indandione (IDO) as a chromogenic reagent to form charge transfer complexes with the studied drugs and produce colored reaction products with an absorbance maximum at 522 ... إقراء المزيد
