A multicenter, randomized, double-blind, placebo-controlled clinical trial to evaluate the efficacy and safety of sumatriptan naproxen sodium succinate tablets in the treatment of acute migraine attacks.

Migraine is a common chronic nerve vascular disease, the disease characteristic to break out repeatedly, one side or both sides of the pulsatile partial side head, severe headache and can combine autonomic nervous system dysfunction such as nausea, vomiting, photophobia, and fear the symptom such as, about one-third of patients with migraine aura symptoms can appear before the onset of the nervous system. Sulaptan is a 5-HT1 receptor agonist with a high affinity for binding to 5-HT1b and 5-HT1D receptors. Naproxen is an NSAID that inhibs the synthesis of inflammatory mediators. Thus, sulaptan and naproxen alleviate migraine through different pharmacological mechanisms of action. For this test center, randomized, double-blind, placebo-controlled, parallel-group Ⅲ phase of clinical trial, aimed to verify shu Ma Putan naproxen sodium treatment of acute migraine headache, headache complete remission rate after 2 hours, evaluation of succinic acid shu Ma Putan naproxen sodium tablets for efficacy and safety of the treatment of acute migraine attacks.
