Abstract

A titration dosing regimen for the administration of controlled release tramadol analgesic to patients. The titration dosing regimen provides a significant reduction in the occurrence of adverse effects from the introduction of controlled released tramadol dosing, thus increasing patient compliance and medication tolerability.

Claims

1-8. -8. (canceled)

9. A dosage regimen for administering tramadol to a patient comprising administering:

about 100 mg of tramadol in a controlled release dosage form once-a-day on days 1 through 7;

then about 200 mg of tramadol in a controlled release dosage form once-a-day on days 8 through 14;

then about 300 mg of tramadol in a controlled release dosage form once-a-day on day 15 and optionally thereafter.

10. The dosage regimen of claim 9 wherein the controlled release dosage forms are each oral dosage forms.

11. The dosage regimen of claim 10 wherein the tramadol is present in each oral dosage form in the form of tramadol hydrochloride.

12. The dosage regimen of claim 11 each oral dosage form provides in vitro release of tramadol hydrochloride for about 24 hours or longer.

13. The dosage regimen of claim 9 comprising administering about 300 mg of tramadol in a controlled release dosage form once-a-day on days 15 through 21 and optionally thereafter.

14. The dosage regimen of claim 13 wherein 100 mg of tramadol is administered on days 1 through 7;

15. The dosage regimen method of claim 14 wherein the tramadol is present in each oral dosage form in the form of tramadol hydrochloride.

16. The dosage regimen method of claim 15 wherein each oral dosage form provides an in vitro release of tramadol hydrochloride of about 24 hours or more.

17. A dosage regimen for administering tramadol to a patient comprising administering:

about 175 mg to about 225 mg of tramadol in a controlled release dosage form once-a-day for about 4 to about 10 days;

then about 275 mg to about 325 mg of tramadol in a controlled release dosage form once-a-day for at least 1 day and optionally thereafter.

18. The dosage regimen of claim 17 wherein the controlled release dosage forms are each oral dosage forms.

19. The dosage regimen of claim 18 wherein the tramadol is present in each oral dosage form in the form of tramadol hydrochloride.

21. The dosage regimen of claim 17 comprising administering about 275 mg to about 325 mg of tramadol in a controlled release dosage form once-a-day for at least 6 days and optionally thereafter.

20. The dosage regimen of claim 20 wherein each oral dosage form provides an in vitro release of tramadol hydrochloride of about 24 hours or more.

22. A dosage regimen for administering tramadol to a patient comprising administering:
