Abstract
In the present work, the electrochemical behavior of an antimigraine drug, almotriptan malate (ALM), on a multiwalled carbon nanotube (MWCNT) film modified glassy carbon electrode under cyclic voltammetry was described for the first time. A significant enhancement in the oxidation peak current of ALM was noticed at MWCNT-GCE. This property was exploited to develop a simple, sensitive and time-saving differential pulse voltammetric method for the determination of ALM in bulk and pharmaceutical samples. A linear relationship was observed between concentration and peak current with a correlation coefficient of 0.9915 in the range of 0.25-37.5μM ALM.
