Tolfenamic acid (a potent inhibitor of prostaglandin biosynthesis), ergotamine tartrate, acetylsalicylic acid, or placebo was administered during 160 migraine attacks in twenty women in a double-blind, cross-over study. Tolfenamic acid and ergotamine were equally effective in reducing the duration and intensity of attacks, but side-effects, especially nausea, were less common with tolfenamic acid. This probably accounted for the patients' preference for tolfenamic acid. The effectiveness of tolfenamic acid in acute migraine attacks accords with the postulated role of prostaglandins in migraine.

In a double-blind cross-over study we compared tolfenamic acid with paracetamol in out-patients with common migraine (migraine without aura). Each patient was treated during (at least) 4 attacks with one of the following alternatives: tolfenamic acid 200 mg, tolfenamic acid 400 mg, paracetamol 500 mg or paracetamol 1000 mg in a randomized sequence. The same sequence of treatments was applied to (preferably) 4 more attacks. Dosage was repeated after 2 h if the attack had not abated. Escape medication was allowed after 4 h if the treatment was inefficient. A total of 83 patients were admitted to the study, but 3 dropped out, while 10 completed less than 4 attacks. Seventy completed 4 attacks, and 58 completed all 8. The total number of attacks treated was 545. We found a significant superiority of tolfenamic acid over paracetamol with regard to effect on pain after 2 h (p less than 0.01), patients' global evaluation (p less than 0.001), and use of escape medication (p less than 0.02). The trend was the same for duration of attacks, confinement to bed during attack and nausea, but the results were not statistically significant. There was no significant difference between the smaller and the larger dose of either drug nor between the need for escape medication, although the trend favoured tolfenamic acid. Side effects were few. Tolfenamic acid is evidently valuable in treatment of migraine.

Tolfenamic acid (TA), a potent inhibitor of prostaglandin (PG) biosynthesis and action, was tested prophylactically against hangover symptoms in 30 healthy volunteers in a double-blind cross-over study. One capsule of TA (200 mg) or placebo was taken before starting to drink alcohol and another before going to bed. The hangover symptoms were evaluated in the morning. TA was found significantly better than placebo in the subjective evaluation of drug efficacy (p less than 0.001) and in reducing the reported hangover symptoms in general (p less than 0.01). In the TA group, significantly lower symptom scores were obtained for headache (p less than 0.01), and for nausea, vomiting, irritation, tremor, thirst and dryness of mouth (all p less than 0.05). In a separate study with eight participants, plasma levels of PGs were followed during ingestion of alcohol with or without TA. The plasma concentrations of PGE2 and TXB2 (a metabolite of thromboxane A2) were lower in the TA group during alcohol ingestion, while PGF2 alpha and 6-keto-PGF1 alpha (a metabolite of prostacyclin) were unaffected. TXB2 correlated with blood alcohol levels in a U-shaped manner.
