Answer to Question 1
Ans: B
Ergotamine relieves migraine headaches by constricting, not dilating, cerebral arterial vessels. The drug's ability to prevent norepinephrine reuptake may add to this effect. The net result is decreased pulsatile blood flow through the cerebral vessels and symptom relief. Ergotamine doesn't decrease peripheral vascular resistance or stimulation of baroreceptors.
