Within certain embodiments, the present invention provides a method for treating an inflammatory disorder in a patient with uninterrupted doses of aminopterin.
1. A method for treating an inflammatory disorder in a patient, comprising administering to said patient a therapeutically effective amount of aminopterin, or a pharmaceutically acceptable salt thereof, in uninterrupted cycles, wherein the therapeutically effective amount of aminopterin, or pharmaceutically acceptable salt thereof, administered per week is between 0.0005 and 0.07 mg per kilogram of patient body weight, and wherein the inflammatory disorder is selected from the group consisting of rheumatoid arthritis, juvenile rheumatoid arthritis, psoriasis, psoriatic arthritis, atopic dermatitis, inflammatory bowel disease, bronchopulmonary dysplasia, and canine atopic dermatitis.
2. A method of claim 1 , wherein the number of uninterrupted cycles is at least 24.
3. A method of claim 1 , wherein the periodicity of the uninterrupted cycles is weekly.
4. A method of claim 1 , wherein the number of doses in each cycle is 2.
5. A method of claim 1 , wherein the number of doses in each cycle is 1.
6. A method of claim 1 , comprising the additional step of using a second drug in a combination therapy.
7. A method of claim 6 , wherein the second drug is folic acid.
8. A method of claim 1 , wherein the amount of aminopterin given in each cycle is less than 0.07 mg aminopterin per kilogram of patient body weight.
9. A method of claim 1 , wherein the therapeutically effective amount of aminopterin, or pharmaceutically acceptable salt thereof, is between 0.1 and 2.0 mg for each cycle.
10. A method of claim 1 , wherein the therapeutically effective amount of aminopterin, or pharmaceutically acceptable salt thereof, is a pharmaceutical composition, and wherein the pharmaceutical composition is a tablet.
11. A method for treating an inflammatory disorder in a patient, comprising administering to said patient a therapeutically effective amount of aminopterin, or a pharmaceutically acceptable salt thereof, wherein the therapeutically effective amount of aminopterin, or pharmaceutically acceptable salt thereof, administered per week is between 0.0005 and 0.07 mg per kilogram of patient body weight, and wherein the inflammatory disorder is selected from the group consisting of rheumatoid arthritis, juvenile rheumatoid arthritis, psoriasis, psoriatic arthritis, arthritis, atopic dermatitis, inflammatory bowel disease, bronchopulmonary dysplasia, and canine atopic dermatitis.
12. A method of claim 11 , wherein the amount of aminopterin, or pharmaceutically acceptable salt thereof, administered is between 0.0005 and 0.05 mg per kilogram of patient body weight.
13. A method of claim 11 , wherein the amount of aminopterin, or pharmaceutically acceptable salt thereof, administered per week is between 0.001 and 0.07 ing per kilogram of patient body weight.
14. A method of claim 11 , wherein the amount of aminopterin, or pharmaceutically acceptable salt thereof, administered per week is between 0.005 and 0.07 mg per kilogram of patient body weight.
15. A method of cLaim 11 , comprising the additional step of using a second drug in a combination therapy.
16. A method of claim 15 , wherein the second drug is folic acid.
17. A method of claim 11 , wherein the therapeutically effective amount of aminopterin, or pharmaceutically acceptable salt thereof, is a pharmaceutical composition, and wherein the pharmaceutical composition is a tablet.
