Indomethacin/prochlorperazine/caffeine: a review of its use in the acute treatment of migraine and in the treatment of episodic tension-type headache

The indomethacin/prochlorperazine/caffeine fixed combination (Difmetré®) combines the NSAID indomethacin with the phenothiazine antiemetic prochlorperazine and caffeine. It is currently available as two oral (effervescent tablet and coated tablet) and two rectal (suppository and low-dose suppository) formulations. Oral and rectal formulations of indomethacin/prochlorperazine/caffeine were effective and generally well tolerated in the treatment of migraine and episodic tension-type headache (TTH) in adult patients participating in randomized, multicentre, active-comparator controlled studies. For the most part, the efficacy of oral indomethacin/prochlorperazine/caffeine did not significantly differ from that of oral sumatriptan in patients with migraine and oral nimesulide in patients with episodic TTH. With rectal administration, indomethacin/prochlorperazine/caffeine was, in general, significantly more effective than sumatriptan in patients with migraine. Thus, oral and rectal formulations of indomethacin/prochlorperazine/caffeine provide a further option in the acute treatment of migraine and in the treatment of episodic TTH in adult patients.
