Posted in on 16.03.10
Mechanism of Action
Generic Imitrex injection contains a chemical called Sumatriptan which is quite identical in nature to serotonin, a neurotransmitter involved in memory, sleep, and depression. The medication itself triggers off very particular receptors detected in the arteries supplying blood to the cerebral cortex.
Migraine headaches are frequently induced by expansion of the cerebral arteries, which gives rise to surplus flow of blood to the head. Sparking off the receptors brings forth vasoconstriction or a reduction in the diameter of blood vessels, which retorts the expansion, checks blood flow and ends migraine pain.
Generic Imitrex injection also creates the action in the trigeminal nerve (the fifth cranial nerve accountable for sensation in the head and face) to decelerate. This decline in action is partly accountable for Generic Imitrex achievement in the intervention of cluster headaches (agonizing chronic headaches connected to the discharge of histamine from cells) too.
