Somatrann Tablet 4'S belongs to the class of medicines called 'antimigraine agents' used to prevent migraine symptoms such as headache, nausea, and vomiting. Migraine is a neurological condition which is characterised by an intense pulsating, throbbing, pounding, debilitating headache which usually occurs on one side of the head; however, it can occur on both sides or shift. Hormonal changes, stress, bright lights, loud sounds, certain foods and drinks can trigger migraine headaches. 

Somatrann Tablet 4'S is a combination of two drugs, namely: Sumatriptan and Naproxen. Sumatriptan acts on the serotonin (5-HT) receptors located in the brain, thereby causing the narrowing of the brain's blood vessels, which in turn affects the blood flow patterns associated with headache. Naproxen is a painkiller which works by blocking the effect of chemical messengers that cause pain.  Thus, Somatrann Tablet 4'S prevents symptoms of migraine-like headache, nausea and vomiting.

Somatrann Tablet 4'S is a combination of two drugs, namely: Sumatriptan and Naproxen. Somatrann Tablet 4'S is indicated for the acute treatment of migraine with or without aura. Sumatriptan is a serotonin receptor agonist that acts on the serotonin (5-HT) receptors located in the brain, which causes the narrowing of the brain's blood vessels, thereby affecting the blood flow patterns with a headache. Naproxen is a pain killer which works by blocking the effect of a chemical messenger known as cyclo-oxygenase (COX) enzymes that make other chemical prostaglandins. By blocking the effect of COX enzymes, lesser prostaglandins are produced, thereby reducing pain in migraine.
