Pharmaceutical compositions comprising meloxicam
Disclosed herein are compositions comprising an NSAID such as meloxicam and/or rizatriptan in combination with a cyclodextrin and/or a carbonate or a bicarbonate. These compositions may be orally administered, for example, to improve the bioavailability or pharmacokinetics of the NSAID for the treatment of pain such as migraine, arthritis, and other conditions. Also disclosed herein are methods of treating pain, such as migraine, comprising administering meloxicam and rizatriptan to a human being suffering from pain, such as migraine. For migraine, these methods may be particularly useful when the meloxicam and rizatriptan are administered while the human being is suffering from an acute attack of migraine pain or migraine aura. In some embodiments, the combination of meloxicam and rizatriptan may be administered in a manner that results in a T max of meloxicam of 3 hours or less.
1. A method of treating migraine, comprising administering a meloxicam and about 8 mg to about 13 mg of a rizatriptan, based upon the weight of rizatriptan in the free base form, to a human being who is suffering from an acute attack of migraine pain or migraine aura, wherein the meloxicam and the rizatriptan are in a single dosage form, wherein the single dosage form is structured so that administering the single dosage form to healthy human subjects would result in a median T max of meloxicam of 90 minutes or less, and an AUC 0-24 of meloxicam of about 30 μg·hr/mL to about 60 μg·hr/mL, wherein the human being has nausea associated with migraine pain, and wherein one hour after the meloxicam and the rizatriptan are administered, the human being experiences greater relief from migraine pain and nausea than the human being would have experienced one hour after receiving the same amount of the rizatriptan alone.
2. The method of claim 1 , wherein the rizatriptan is administered in a salt form in an amount that is a molar equivalent to about 10 mg of rizatriptan in the free base form.
3. The method of claim 2 , wherein the rizatriptan is present as rizatriptan benzoate.
4. The method of claim 1 , wherein about 15 mg to about 25 mg of the meloxicam, based upon the weight of meloxicam in the free acid form, is administered to the human being.
5. The method of claim 1 , wherein about 20 mg of the meloxicam, based upon the weight of meloxicam in the free acid form, is administered to the human being.
6. The method of claim 1 , wherein about 15 mg of the meloxicam, based upon the weight of meloxicam in the free acid form, is administered to the human being.
7. The method of claim 1 , wherein the human being has a history of inadequate response to prior migraine treatments.
8. The method of claim 7 , wherein the rizatriptan is administered in a salt form in an amount that is a molar equivalent to about 10 mg of rizatriptan in the free base form.
9. The method of claim 7 , wherein about 15 mg to about 25 mg of the meloxicam, based upon the weight of meloxicam in the free acid form, is administered to the human being.
10. The method of claim 8 , wherein about 20 mg of the meloxicam, based upon the weight of meloxicam in the free acid form, is administered to the human being.
11. The method of claim 8 , wherein about 15 mg of the meloxicam, based upon the weight of meloxicam in the free acid form, is administered to the human being.
12. The method of claim 1 , wherein two hours after the meloxicam and the rizatriptan are administered, the human being experiences greater pain relief than the human being would have experienced two hours after receiving the same amount of the meloxicam alone.
13. The method of claim 1 , wherein two hours after the meloxicam and the rizatriptan are administered, the human being experiences greater pain relief than the human being would have experienced two hours after receiving the same amount of the rizatriptan alone.
14. A method of treating migraine, comprising administering a meloxicam and about 8 mg to about 13 mg of a rizatriptan, based upon the weight of rizatriptan in the free base form, to a human being who is suffering from an acute attack of migraine pain or migraine aura, wherein the meloxicam and the rizatriptan are in a single dosage form, wherein the single dosage form is structured so that administering the single dosage form to healthy human subjects would result in a median T max of meloxicam of 90 minutes or less, and an AUC 0-24 of meloxicam of about 30 μg·hr/mL to about 60 μg·hr/mL, wherein the human being has nausea associated with migraine pain, and wherein one hour after the meloxicam and the rizatriptan are administered, the human being experiences greater relief from migraine pain and nausea than the human being would have experienced one hour after receiving the same amount of the meloxicam alone.
15. The method of claim 14 , wherein the rizatriptan is administered in a salt form in an amount that is a molar equivalent to about 10 mg of rizatriptan in the free base form.
16. The method of claim 15 , wherein the rizatriptan is present as rizatriptan benzoate.
17. The method of claim 14 , wherein about 15 mg to about 25 mg of the meloxicam, based upon the weight of meloxicam in the free acid form, is administered to the human being.
18. The method of claim 14 , wherein about 20 mg of the meloxicam, based upon the weight of meloxicam in the free acid form, is administered to the human being.
19. The method of claim 14 , wherein about 15 mg of the meloxicam, based upon the weight of meloxicam in the free acid form, is administered to the human being.
20. The method of claim 14 , wherein the human being has a history of inadequate response to prior migraine treatments.
21. The method of claim 20 , wherein the rizatriptan is administered in a salt form in an amount that is a molar equivalent to about 10 mg of rizatriptan in the free base form.
22. The method of claim 21 , wherein about 15 mg to about 25 mg of the meloxicam, based upon the weight of meloxicam in the free acid form, is administered to the human being.
23. The method of claim 22 , wherein about 20 mg of the meloxicam, based upon the weight of meloxicam in the free acid form, is administered to the human being.
24. The method of claim 22 , wherein about 15 mg of the meloxicam, based upon the weight of meloxicam in the free acid form, is administered to the human being.
25. The method of claim 14 , wherein two hours after the meloxicam and the rizatriptan are administered, the human being experiences greater pain relief than the human being would have experienced two hours after receiving the same amount of the meloxicam alone.
26. The method of claim 14 , wherein two hours after the meloxicam and the rizatriptan are administered, the human being experiences greater pain relief than the human being would have experienced two hours after receiving the same amount of the rizatriptan alone.
