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 combination of a meloxicam and a rizatriptan to a human being in need thereof, wherein the combination of the meloxicam and the rizatriptan is administered while migraine pain is mild, and wherein the combination contains about 15 mg to about 30 mg of the meloxicam free acid, or a molar equivalent amount of a salt form of meloxicam.
2. The method of claim 1 , wherein the combination of the meloxicam and the rizatriptan is orally administered, and wherein the combination contains about 8 mg to about 13 mg of the rizatriptan free base, or a molar equivalent amount of a salt of rizatriptan.
3. The method of claim 2 , wherein the human being experiences a reduction in migraine pain at 30 minutes after the combination of the meloxicam and the rizatriptan is orally administered.
4. The method of claim 2 , wherein the human being experiences a reduction in migraine pain at 60 minutes after the combination of the meloxicam and the rizatriptan is orally administered.
5. The method of claim 2 , wherein the human being experiences a reduction in migraine pain at 90 minutes after the combination of the meloxicam and the rizatriptan is orally administered.
6. The method of claim 5 , wherein the human being experiences a reduction in migraine pain at 24 hours after the combination of the meloxicam and the rizatriptan is orally administered.
7. The method of claim 2 , wherein the combination of the meloxicam and the rizatriptan contains about 20 mg of the meloxicam free acid, or a molar equivalent amount of the salt form of meloxicam.
8. The method of claim 2 , wherein the human being experiences freedom from the human being's most bothersome migraine-associated symptom at two hours after the combination is orally administered, and wherein the human being's most bothersome migraine-associated symptom is nausea, photophobia, or phonophobia.
9. The method of claim 8 , wherein the combination of the meloxicam and the rizatriptan contains about 20 mg of the meloxicam free acid, or a molar equivalent amount of the salt form of meloxicam.
10. The method of claim 2 , wherein the migraine is associated with an aura.
11. The method of claim 2 , wherein the human being has reduced use of rescue medication after the combination of the meloxicam and the rizatriptan is orally administered.
12. The method of claim 2 , wherein the human being does not use rescue medication after the combination of the meloxicam and the rizatriptan is orally administered.
13. The method of claim 2 , wherein the human being achieves pain freedom by two hours after the combination of the meloxicam and the rizatriptan is orally administered.
14. The method of claim 2 , wherein the human being achieves pain freedom by two hours after the combination of the meloxicam and the rizatriptan is orally administered, and wherein the pain freedom continues for at least 24 hours.
15. The method of claim 2 , wherein the human being achieves pain freedom by two hours after the combination of the meloxicam and the rizatriptan is orally administered, and wherein the pain freedom continues for at least 48 hours.
16. The method of claim 2 , wherein the human being achieves the ability to perform normal activities at 24 hours after the combination of the meloxicam and the rizatriptan is orally administered.
17. The method of claim 2 , wherein the human being has a patient global impression of change that is “much improved” or “very much improved” at 2 hours after the combination of the meloxicam and the rizatriptan is orally administered.
18. The method of claim 2 , wherein the combination is in a dosage form, and wherein the dosage form has the property that administering the dosage form to a healthy human subject under fasted conditions results in a T max of meloxicam that is two hours or less.
19. The method of claim 2 , wherein the combination is in a dosage form, and wherein the dosage form has the property that administering the dosage form to a healthy human subject under fasted conditions results in a T max of meloxicam that is one hour or less.
20. A method of treating migraine, comprising administering a combination of a meloxicam and a rizatriptan to a human being in need thereof, wherein the combination of the meloxicam and the rizatriptan is administered while migraine pain is mild, and wherein the migraine pain does not progress beyond mild after the combination of the meloxicam and the rizatriptan is administered.
