sumatriptan succinate is a selective 5-ht1 receptor agonist with specificity towards 5-ht1d, 5-ht1b and 5-ht1a. in addition, the
physicochemical properties of sumatriptan succinate can be characterized using ft-ir, hplc, sem and xrd. it has been reported
that sumatriptan succinate can be produced via reactive precipitation without the presence of surfactants. further studies show that
molecules of sumatriptan succinate are carried through cells using liposomes, with positively charged liposomes exhibiting the
highest loading efficiency.
