[Many snips in above passage].
My sister has been given "Imitrex" (Sumatriptan succinate) for a third, disabling migraine.
The FAQ in the booklet for Imitrex says :
"Imitrex connects w/certain receptors near the blood vessel wall and causes some of thee
blood vessels to constrict...When Imitrex connects to its receptors, it 'unlocks' the door
of the cell. This causes a chain of events that lead to blood vessel constriction (narrowing)."
There's a contradiction here.I don't trust their "explanation" :
Constriction in the main vessels of the left brain are found in schizophrenics according to
my biopsychology text (I think you can apply the misalignment of MLT and the lack of PRL
release directly to the onset of schizophrenia).
Is there any info on sumatriptan succinate ?
