The efficacy of safety of naproxen sodium and ergotamine tartrate were compared for the treatment of acute migraine attack in a randomized, parallel trial with 114 participating patients. At the start of symptoms, patients took either three tablets of naproxen sodium (275 mg each) or one of an ergotamine combination (containing 2 mg ergotamine tartrate, 91.5 mg caffeine, and 50 mg cyclizine chlorhydrate). Patients were followed for three months or until six attacks were monitored, whichever came first. Both medications substantially shortened the duration of migraine attacks and reduced the severity of symptoms. When the test medications were taken within 2 h of onset of attack, naproxen sodium was statistically significantly more effective than the ergotamine combination in reducing the severity of headache pain, nausea, and lightheadedness. The ergotamine combination was associated with significantly more vomiting, need for rescue medication, and side effects than was naproxen sodium. Four patients required discontinuation of the ergotamine combination and one of naproxen sodium. Both patients and investigators rated tolerance for naproxen sodium as superior to tolerance for the ergotamine combination. Naproxen sodium seems to be an effective and safe treatment for migraine attacks.

Naproxen sodium, a potent inhibitor of prostaglandin biosynthesis and platelet aggregation, was studied for efficacy in migraine prophylaxis in a randomized, double-blind, placebo-controlled, crossover trial. On naproxen treatment, 52% of the patients had no severe headaches, whereas 19% had no severe headaches during placebo. Naproxen sodium was much better than placebo when patients' diaries were reviewed for severity of attacks, nausea, vomiting, activity reduction, duration of headache, and decreased use of therapeutic medication. The degree of platelet inhibition did not correlate with efficacy in preventing headache. Naproxen sodium can be recommended as a drug of first choice for migraine prevention.

Studies have elucidated the regulatory interplay between ovarian hormonal changes, prostaglandin levels and the evolution of intrauterine pressure that leads to dysmenorrhea. These studies substantiated the premise that primary dysmenorrhea is caused by endogenous prostaglandin excess and prompted clinical trials with naproxen sodium (Anaprox) in patients with primary dysmenorrhea. The primary action of prostaglandin is constriction of uterine blood vessels, with consequent anoxia and sustained myometrial contraction. Cyclic uterine contractions evolve later but gradually, with the progress of time. However, the cyclic contractions are not perceived as painful. It is important to realize that the source of uterine pain in dysmenorrhea is the high resting intrauterine pressure (tonus). Penetration of excess prostaglandins into general circulation fully accounts for the systemic symptoms of dysmenorrhea (nausea, vomiting, diarrhea, headache, etc). Rational treatment of dysmenorrhea should be directed at elimination of the excess prostaglandin action. Naproxen sodium and other prostaglandin synthesis inhibitors decrease intrauterine resting pressure as well as amplitude and frequency of uterine contractions and reduce the uterine concentrations of prostaglandins. These changes are associated with substantial pain relief. Thus, naproxen sodium and other prostaglandin synthesis inhibitors present a logical treatment modality to be used in dysmenorrhea.
