c) decreased average plasma levels of at least one metabolite of said compound per dosage unit thereof as compared to the non-isotopically enriched compound;

d) increased average plasma levels of at least one metabolite of said compound per dosage unit thereof as compared to the non-isotopically enriched compound; or

e) an improved clinical effect during the treatment in said subject per dosage unit thereof as compared to the non-isotopically enriched compound.

13. The method as recited in claim 1 , wherein said compound has at least two of the following properties:

a) decreased inter-individual variation in plasma levels of said compound or a metabolite thereof as compared to the non-isotopically enriched compound;

b) increased average plasma levels of said compound per dosage unit thereof as compared to the non-isotopically enriched compound;

c) decreased average plasma levels of at least one metabolite of said compound per dosage unit thereof as compared to the non-isotopically enriched compound;

d) increased average plasma levels of at least one metabolite of said compound per dosage unit thereof as compared to the non-isotopically enriched compound; or

e) an improved clinical effect during the treatment in said subject per dosage unit thereof as compared to the non-isotopically enriched compound.

14. The method as recited in claim 1 , wherein the method affects a decreased metabolism of the compound per dosage unit thereof by at least one polymorphically-expressed cytochrome P450 isoform in the subject, as compared to the corresponding non-isotopically enriched compound.

15. The method as recited in claim 14 , wherein the cytochrome P 450 isoform is selected from the group consisting of CYP2C8, CYP2C9, CYP2C19, and CYP2D6.

16. The method as recited in claim 1 , wherein said compound is characterized by decreased inhibition of at least one cytochrome P 450 or monoamine oxidase isoform in said subject per dosage unit thereof as compared to the non-isotopically enriched compound.
