Pharmaceutical compositions comprising meloxicam
Disclosed herein are compositions comprising an NSAID such as meloxicam 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 conditions such as pain.
1. A method of treating pain comprising: orally administering a solid dosage form to a human being for at least six consecutive days, wherein the solid dosage form comprises: 1) a complex of meloxicam and a sulfobutyl ether β-cyclodextrin (SBEβCD), 2) a bicarbonate, and 3) esomeprazole, wherein orally administering the solid dosage form to the human being results in a T max of meloxicam that is shorter than a T max of a reference solid dosage form that: 1) contains the same amount of meloxicam, 2) does not contain an SBEβCD, and 3) does not contain a bicarbonate, and wherein the average gastric pH of the human being on the sixth consecutive day is at least 3.5.
2. The method of claim 1 , wherein the solid dosage form is in a tablet form.
3. The method of claim 1 , wherein the solid dosage form comprises about 1 mg to about 50 mg of meloxicam.
4. The method of claim 3 , wherein the solid dosage form comprises about 15 mg of meloxicam.
5. The method of claim 3 , wherein the solid dosage form comprises about 20 mg of meloxicam.
6. The method of claim 1 , wherein the bicarbonate is sodium bicarbonate or potassium bicarbonate.
7. The method of claim 6 , wherein the solid dosage form comprises 400 mg to 900 mg of sodium bicarbonate.
8. The method of claim 6 , wherein the solid dosage form comprises 450 mg to 550 mg of sodium bicarbonate.
9. The method of claim 6 , wherein the solid dosage form comprises 500 mg of sodium bicarbonate.
10. The method of claim 1 , wherein about 30 mg to about 50 mg of esomeprazole is present in the solid dosage form.
11. The method of claim 1 , wherein about 40 mg of esomeprazole is present in the solid dosage form.
12. The method of claim 1 , wherein the SBEβCD has about 6 to about 7 sulfobutyl ether groups for each molecule of β-cyclodextrin.
13. The method of claim 1 , wherein the solid dosage form contains about 75 mg to about 150 mg of the SBEβCD.
14. The method of claim 1 , wherein the solid dosage form contains about 100 mg to about 140 mg of the SBEβCD.
15. The method of claim 14 , wherein the solid dosage form contains about 100 mg of the SBEβCD.
16. The method of claim 1 , wherein the solid dosage form has been shown to have a median T max of meloxicam that is less than about 2 hours in fasted human subjects.
17. The method of claim 1 , wherein the solid dosage form has been shown to have a median T max of meloxicam that is within about 80 minutes in fasted human subjects.
18. The method of claim 1 , wherein the solid dosage form has been shown to have a median T max of meloxicam that is less than about 1 hour in fasted human subjects.
19. The method of claim 1 , wherein the solid dosage form has been shown to have a median time to half-maximal plasma concentration of meloxicam that is less than about 30 minutes in fasted human subjects.
20. The method of claim 1 , wherein the solid dosage form has been shown to have a median T max of meloxicam that is at least 5 times shorter as compared to the reference solid dosage form in fasted human subjects.
21. The method of claim 1 , wherein the solid dosage form has been shown to have a median C max of meloxicam that is at least 1800 ng/mL in fasted human subjects.
22. The method of claim 1 , wherein the solid dosage form has been shown to have a median C max of meloxicam that is about 2000 ng/mL to about 2500 ng/mL in fasted human subjects.
23. The method of claim 1 , wherein the pain is inflammatory pain.
24. The method of claim 1 , wherein the solid dosage form is orally administered to the human being to treat pain associated with osteoarthritis, rheumatoid arthritis, or juvenile rheumatoid arthritis.
