2. The method of claim 1 further comprising administering a p450 3A4 promoter.
3. The method of claim 2 wherein the tyrosine hydroxylase inhibitor and the p450 3A4 promoter are administered simultaneously.
4. The method of claim 2 wherein the tyrosine hydroxylase inhibitor and the p450 3A4 promoter are administered orally, subcutaneously, intravenously, transdermally, vaginally, rectally or in any combination thereof.
5. The method of claim 4 wherein the transdermal administration is performed in combination with oleic acid, 1-methyl-2-pyrrolidone, or dodecylnonaoxyethylene glycol monoether.
6. The method of claim 1 wherein the tyrosine hydroxylase inhibitor and the p450 3A4 promoter are administered during a cycle consisting of five to seven days of administering the tyrosine hydroxylase inhibitor and the p450 3A4 promoter, and one to two days of not administering the tyrosine hydroxylase inhibitor and the p450 3A4 promoter.
7. The method of claim 6 that includes at least six of said cycles.
8. The method of claim 1 comprising administering α-methyl-D-tyrosine to said subject.
9. The method of claim 1 comprising administering α-methyl-DL-tyrosine in a racemic form to said subject.
10. The method of claim 1 wherein 60 mg of the tyrosine derivative is administered orally and 0.25 mL of a 2 mg/mL suspension of the tyrosine derivative is administered subcutaneously.
11. The method of claim 2 wherein the p450 3A4 promoter is 5, 5-diphenylhydantoin.
12. The method of claim 2 wherein the p450 3A4 promoter is valproic acid or carbamazepine.
13. The method of claim 1 wherein the subject is a human.
14. The method of claim 1 further comprising assessing progression of said hyperglycemia in said subject.
