These divide into two groups:
Sumatriptan, Rizatriptan, Zolmitriptan, Eletriptan and Almotriptan have a higher speed of onset.
Naratriptan & Frovatriptan have a lower side-effect profile, and also possibly less chance of headache recurrence.
Interestingly, someone who hasn’t responded to one triptan still has an 80% chance of responding to another. (Which doesn’t sound quite right to me because I remember hearing that triptans only have about a 50% chance of working at all. Still, whatever the figure, the message is clear.)
