Generic Imitrex 100mg
Imitrex is a prescription drug administered to relieve the symptoms of migraines and cluster headaches. It cannot prevent migraine episodes, but if the attack has already happened, it can relieve the pain, nausea, light sensitivity and other migraine-associated symptoms. Imitrex works by stimulating specific receptors in the blood vessels of the brain, which leads to the constriction of the vessels (it's believed that dilation of these vessels causes migraine).
What is Imitrex?
Imitrex is a prescription medication used to relieve and reduce migraine headaches with or without aura. Imitrex works only if the headache has already started, it will not prevent an attack or reduce the number of migraine episodes. Imitrex can also be administered for the treatment of cluster headaches.
How does Imitrex work?
Sumatriptan is the active component of Imitrex. It belongs to the class of medications known as specific and selective agonists of 5HT1-receptors or triptans. By activating these receptors in the system of the carotid arteries, Imitrex causes their constriction without affecting the cerebral blood flow. The dilation and edema of these arteries are thought to be the cause of migraine attacks.
How to take Imitrex?
Imitrex is manufactured in the form of pills in the following dosages - 25 mg, 50 mg, 100 mg; and in the form of a nasal spray. The choice of the dose in every particular case should be made by a doctor taking into account individual characteristics of a patient. If a migraine attack returns or the patient has partially responded to the initial dose, a second dose may be taken after 2 hours. The therapeutic effect can be observed in about 30 minutes after taking the medicine. The maximum daily dose of Imitrex should not exceed 200 mg.
