Abstract

The invention provides improved methods for coadministration of colchicine with drugs metabolized by CYP3A4 (anciently referred to as cytochrome P450 isozyme 3A4) or the P-glycoprotein transporter, but not both. The method enables non-toxic coadministration of colchicine and the second drug at their ordinary levels safely and effectively without reducing the dose or frequency for either drug.

Claims

1-20. -20. (canceled)

21. A method of treating a patient for an inflammatory disorder, wherein the inflammatory disorder is chronic gout, familial Mediterranean fever or Behç

et'"'"'s disease, with colchicine while concomitantly administering a second drug that is not an inhibitor of the cytochrome P450 3A4 isoenzyme (CYP3A4) but is an inhibitor of P-glycoprotein 1 (P-gp), wherein the second drug is propafenone, wherein the method comprises;

a) administering to the patient a therapeutically effective fixed maintenance dose of colchicine in an amount of from about 0.6 to about 1.2 mg/day, for a maintenance period of a plurality of days, without administering propafenone;

b) after step (a), administering to the patient one or more therapeutically effective doses of propafenone; and

c) concomitantly with step (b), administering to the patient the fixed maintenance dose of colchicine of step (a) without dose reduction.

22. The method of claim 21, wherein propafenone is administered at a dose of from 300 mg/day to 900 mg/day.

23. The method of claim 21, wherein said fixed maintenance dose of colchicine is 0.6 mg/day.

24. The method of claim 21, wherein said fixed maintenance dose of colchicine is 1.2 mg/day.

25. The method of claim 21, wherein the inflammatory disorder is chronic gout.

26. The method of claim 21, wherein said plurality of days comprises at least 7 days.

27. The method of claim 21, wherein said fixed maintenance dose of colchicine is 0.6 mg/day, and said inflammatory disorder is chronic gout.

28. A method of treating a patient for an inflammatory disorder, wherein the inflammatory disorder is chronic gout, familial Mediterranean fever or Behç

et'"'"'s disease, by administering colchicine while concomitantly administering an inhibitor of P-glycoprotein 1 (P-gp) that is not an inhibitor of the cytochrome P450 3A4 isoenzyme (CYP3A4), wherein the inhibitor of P-gp is propafenone, wherein the method comprises;

a) administering to the patient a plurality of therapeutically effective doses of propafenone for a plurality of days without administering colchicine;

b) after step (a), administering to the patient one or more fixed maintenance doses of colchicine in an amount from about 0.6 to about 1.2 mg/day;

c) concomitantly with step (b) administering to the patient a plurality of effective doses of propafenone;

d) after step (c), discontinuing administration of propafenone and continuing to administer the fixed maintenance doses of colchicine administered in step (b) without dose adjustment.

29. The method of claim 28, wherein said fixed maintenance dose of colchicine is 0.6 mg/day, and said inflammatory disorder is chronic gout.

30. The method of claim 28, wherein said fixed maintenance dose of colchicine is 0.6 mg/day, said inflammatory disorder is chronic gout, and said propafenone is administered at a dose of from 300 mg/day to 900 mg/day.

31. The method of claim 28, wherein said fixed maintenance dose of colchicine is 1.2 mg/day, and said inflammatory disorder is chronic gout.

32. The method of claim 28, wherein said fixed maintenance dose of colchicine is 1.2 mg/day, said inflammatory disorder is chronic gout, and said propafenone is administered at a dose of from 300 mg/day to 900 mg/day.
