wherein the respective amounts of said 5-HT agonist and said LA-NSAID in said composition are effective, upon concomitant administration to said patient of one or more of said unit dosage forms of said composition, to produce longer lasting efficacy compared to the administration of said 5-HT agonist in the absence of said LA-NSAID or the administration of said LA-NSAID in the absence of said 5-HT agonist.

4. A therapeutic package for dispensing to, or for use in dispensing to, a migraine headache patient, which comprises: (a) one or more unit dosage forms, each unit dosage form comprising: (i) a 5-HT agonist, wherein said 5-HT agonist is a triptan; and (ii) a long-acting, non-steroidal, anti-inflammatory drug (LA-NSAID), wherein said LA-NSAID has a pharmacokinetic half-life of at least 4 hours and a duration of action of at least 6 hours;

wherein the respective amounts of said 5-HT agonist and said LA-NSAID in said unit dosage f6 rms are effective, upon concomitant administration to said patient of one or more of said unit dosage forms, to produce longer lasting efficacy compared to the administration of said 5-HT agonist in the absence of said LA-NSAID or the administration of said LA-NSAID in the absence of said 5-HT agonist; and (b) a finished pharmaceutical container therefore, said container containing said unit dosage form or unit dosage forms, and further comprising labeling directing the use of said package in the treatment of migraine headache.

5. A method for producing longer lasting efficacy in a migraine headache patient which comprises: (a) administering a 5-HT agonist to said patient, wherein said 5-HT agonist is a triptan; and (b) administering a long-acting, non-steroidal, anti-inflammatory drug (LA-NSAID) to said patient, wherein said LA-NSAID has a pharmacokinetic half-life of at least 4 hours and a duration of action of at least 6 hours; wherein: (i) said 5-HT agonist and said LA-NSAID are concomitantly administered in unit dosage form after the onset of symptoms associated with migraine headache; and (ii) the respective amounts of said 5-HT agonist and said LA-NSAID administered to said patient are effective to produce longer lasting efficacy compared to the administration of said 5-HT agonist in the absence of said LA-NSAID or the administration of said LA-NSAID in the absence of said 5-HT agonist.

6. The method or composition of any one of claims 1-5, wherein said 5-HT agonist is sumatriptan.

7. The method or composition of any one of claims 1-5, wherein said 5-HT agonist is sumatriptan non-parenterally administered in an amount of from about 25 to 100 mg.

8. The method or composition of any one of claims 1-5, wherein said 5-HT agonist and said said LA-NSAID are administered orally, intranasally, rectally, or sublingually.

9. The method or composition of any one of claims 1-5, wherein said 5-HT agonist is sumatriptan administered parenterally in an amount of about 6 mg.

10. The method or composition of any one of claims 1-5, wherein said LA-NSAID is naproxen or a pharmaceutically acceptable salt thereof.

11. The method or composition of any one of claims 1-5, wherein said LA-NSAID is naproxen or a pharmaceutically acceptable salt in an amount of greater than 200 mg.
