Medicine Description megatab 100mg
Megatab 100mg Tablets is a medication that primarily functions as a selective agonist for serotonin (5-HT) receptors, specifically the 5-HT1B and 5-HT1D subtypes. By binding to these receptors in the cranial vasculature, sumatriptan effectively induces vasoconstriction of dilated cranial blood vessels, which alleviates the migraine-associated pain. The activation of these receptors also inhibits the release of pro-inflammatory neuropeptides, thereby reducing the transmission of pain signals to the central nervous system. This dual mechanism of action not only tackles the immediate symptoms of a migraine but is also instrumental in counteracting the underlying pathophysiological processes involved in migraine attacks.
