  • Title: Efficacy of parecoxib, sumatriptan, and rizatriptan in the treatment of acute migraine attacks.

    Abstract:
    Triptans and analgetic nonsteroidal inflammatory drugs reduce acute pain syndromes in migraine. A further treatment option for an acute headache attack in patients with migraine may be the application of cyclooxygenase-2-specific inhibitors, as they have anti-inflammatory and analgesic properties. The objective of this pilot study was to investigate the effects of an oral fast-dissolving tablet of 10 mg of rizatriptan, an intravenous infusion of 40 mg of parecoxib, and a subcutaneous pen injection of sumatriptan (6 mg/0.5 mL) on pain relief in 3 cohorts of patients with episodic migraine. They were treated owing to the acute onset of a pain attack as a case of emergency. They were randomized to treatment with sumatriptan, rizatriptan, or parecoxib. The participants completed a visual analog scale for pain intensity at baseline before the drug administration and then after intervals of 20, 30, 60, and 120 minutes. Rizatriptan, parecoxib, and sumatriptan reduced pain symptoms. Twenty and 30 minutes after drug intake, rizatriptan was more efficacious than parecoxib and sumatriptan, and parecoxib was more effective than sumatriptan. Only a significant difference between rizatriptan and sumatriptan was found after 60 and 120 minutes. This trial demonstrates the effectiveness of a parecoxib infusion in the treatment of acute migraine and that the circumvention of the first pass effect of the liver by rizatriptan may be beneficial for fast pain relief.
