WHAT IS CLAIMED IS:

1. A composition useful for the treatment of obesity, depression, drug abuse and narcolepsy comprising:
a. a norepinephrine precursor; and
b. a norepinephrine re-uptake inhibitor.

2. The composition of claim 1 further comprising an effective amount of one or more enzymatic cofactors for the biosynthesis of norepinephrine.

3. The composition of claims 1 or 2 and a pharmaceutically acceptable carrier.

4. The composition of claim 3 in the form of a liquid, a suspension, a tablet, a dragee, an injectable solution, or a suppository.

5. The composition of claim 2 wherein the enzymatic cofactors include at least one of pyridoxine, ascorbic acid, or the pharmaceutically acceptable salts thereof in an amount, effective to enzymatically cofactor biosynthesis of norepinephrine.

6. The composition of claim 1 wherein the norepinephrine precursor is selected from the group consisting of L-tyrosine and L-phenylalanine, or the pharmaceutically acceptable salts thereof.

7. The composition of claim 6 wherein the norepinephrine precursor is L-tyrosine.

8. The composition of claim 1 wherein the norephinephrine re-uptake inhibitor is selected from the group consisting of desipramine, imipramine, amoxapine, nortriptyline, protriptyline, and maprotiline, or the pharmaceutically acceptable salts thereof.

9. The composition of claim 8 wherein the norepinephrine re-uptake inhibitor is desipramine.

10. The composition of claim 1 comprising, per part by weight of the norepinephrine re-uptake inhibitor or an equivalent amount of the pharmaceutically acceptable salt of said norepinephrine re-uptake inhibitor, 0.5-500 parts by weight of said norepinephrine precursor or an equivalent amount of the pharmaceutically acceptable salt of said norepinephrine precursor.

11. The composition of claim 5 comprising, per part by weight of the norepinephrine re-uptake inhibitor or an equivalent amount of the pharmaceutically acceptable salt of said norepinephrine re-uptake inhibitor, 0.5-500 parts by weight of said norepinephrine precursor, or an equivalent amount of the pharmaceutically acceptable salt of said norepinephrine precursor, 0.05-4 parts by weight of pyridoxine or an equivalent amount of a pharmaceutically acceptable salt of pyridoxine, and 0.4-20 parts by weight of said ascorbic acid or an equivalent amount of a pharmaceutically acceptable salt of said ascorbic acid.

12. The composition of claim 1 comprising, per unit dose, 125-2000 mg of said norepinephrine precursor and 10-75 mg of said norepinephrine re-uptake inhibitor.

13. The composition of claim 7 comprising, per unit dose, 125-2000 ag of L-tyrosine and 10-75 mg of said norepinephrine re-uptake inhibitor.

14. The composition of claim 8 comprising, per unit dose, 10-75 mg of desipramine and 125-2000 mg of a norepinephrine precursor.

15. The composition of claim 5 comprising, per unit dose, 125-2000 mg of said norepinephrine precursor, 10-75 mg of said norepinephrine re-uptake inhibitor, 10-100 mg of pyridoxine, and 50-500 mg of ascorbic acid.

16. The composition of claim 15 wherein the said norepinephrine precursor is L-tyrosine and the said norepinephrine re-uptake inhibitor is desipramine.

17. A method for treating obesity, depression, drug abuse, or narcolepsy in an animal comprising administering to said animal a composition comprising:
a. a norepinephrine precursor; and
b. a norepinephrine re-uptake inhibitor.

18. The method of claim 17 wherein said composition further comprises one or more enzymatic cofactors for the biosynthesis of norepinephrine.

19. The method of claim 18 wherein said enzymatic cofactors include at least one of pyridoxine, ascorbic acid or the pharmaceutically acceptable salts thereof in an amount, effective to enzymatically cofactor biosynthesis of norepinephrine.

20. The method of claim 17 wherein said animal is a human.

21. The method of claims 17, 18, or 19 wherein said norepinephrine precursor is selected from the group of consisting of L-phenylalanine, L-tyrosine, and the pharmaceutically acceptable salts of L-phenylalanine and L-tyrosine, and said norepinephrine re-uptake inhibitor is selected from the group consisting of desipramine, imipramine, amoxapine, nortriptyline, protriptyline, and maprotiline, and the pharmaceutically acceptable salts of desipramine, imipramine, amoxapine, nortriptyline, protriptyline, and maprotiline.

22. The method of claim 17 wherein said composition comprises per part by weight of said norepinephrine re-uptake inhibitor or an equivalent amount of the pharmaceutically acceptable salt of said norepinephrine re-uptake inhibitor, 0.5-500 parts by weight of the norepinephrine precursor or an equivalent amount of the pharmaceutically acceptable salt thereof.

23. The method of claim 19 wherein said composition comprises, per part by weight of said norepinephrine re-uptake inhibitor or an equivalent amount of the pharmaceutically acceptable salt of said norepinephrine re-uptake inhibitor, 0.5-500 parts by weight of said norepinephrine precursor, 0.05-4 parts by weight of pyridoxine or an equivalent amount of a pharmaceutically acceptable salt of pyridoxine, and 0.4-20 parts by weight of said ascorbic acid or an equivalent amount of a pharmaceutically acceptable salt of said ascorbic acid.

24. The method of claims 17, 18 or 19 wherein said composition is administered to said animal one to eight times per day, each unit dose containing 125-2000 mg of said norepinephrine precursor or an equivalent amount of the pharmaceutically acceptable salt of said norepinephrine precursor, 10-75 mg of said norepinephrine re-uptake inhibitor or an equivalent amount of the pharmaceutically acceptable salt of said norepinephrine re-uptake inhibitor, 10-100 mg of said pyridoxine or an equivalent amount of the pharmaceutically acceptable salt of said pyridoxine, and 50-500 mg. of said ascorbic acid or an equivalent amount of the pharmaceutically acceptable salt of said ascorbic acid.

25. The method of claim 17, wherein said composition comprises, per unit dose, 1 gm L-tyrosine and 25 mg desipramine administered four times daily.

26. The method of claim 19, wherein said composition comprises, per unit dose, 1 gm L-tyrosine, 25 mg desipramine, 50 mg pyridoxine and 250 mg ascorbic acid.
