Compositions comprising citrulline and leucine and their use in the treatment of diabetes and metabolic syndrome
View Patent ↗The present disclosure relates generally to compositions that comprise citrulline and leucine or a metabolite thereof including, for example, a synergistic amount of citrulline and leucine. Such compositions may be used in methods for the treatment of metabolic syndrome, hyperglycemia, and/or hyperinsulinemia.
1. A method of treating a disease or condition hyperinsulinemia in a subject in need thereof, the method comprising: administering to the subject a therapeutically effective amount of citrulline and a therapeutically effective amount of leucine or a metabolite thereof.
2. The method of claim 1 , wherein the metabolite of leucine is hydroxy isocaproic acid (HICA) or beta-hydroxy-beta-methylbutyrate (HMB).
3. The method of claim 1 , wherein the therapeutically effective amount of citrulline and the therapeutically effective amount of leucine or a metabolite thereof results a synergistic effect.
4. The method of claim 1 , wherein the citrulline and the leucine or metabolite thereof are administered to the subject using a regimen selected from the group consisting of weekly, daily, two times a day, and three times a day.
5. The method of claim 1 , wherein the subject is administered a fixed amount of the citrulline and the leucine or metabolite thereof.
6. The method of claim 1 , wherein the subject is administered a weight based dose of the citrulline and the leucine or metabolite thereof.
7. The method of claim 1 , wherein a pharmaceutical composition is administered to the subject that comprises both the therapeutically effective amount of citrulline and the therapeutically effective amount of leucine or a metabolite thereof.
8. The method of claim 1 , wherein the therapeutically effective amount of citrulline and the therapeutically effective amount of leucine or a metabolite thereof are administered orally.
9. The method of claim 1 , wherein the method is effective to achieve reduction of hyperinsulinemia.
10. The method of claim 1 , wherein the therapeutically effective amount of citrulline and the therapeutically effective amount of leucine or a metabolite thereof is administered in conjunction with at least one additional treatment method, said additional treatment method comprising administering at least one pharmaceutical composition comprising an active agent selected from the group consisting of: a sulfonylurea, a meglitinide, a biguanide, an alpha-glucosidase inhibitor, a thiazolidinedione, a DPP-IV inhibitor, a glucagon-like peptide (GLP)-1 analog, and insulin.
11. The method of claim 6 , wherein the weight based dose is 1.0 g/kg of the citrulline and 1.0 g/kg of the leucine.
12. The method of claim 1 , wherein the subject is administered protein in conjunction with the citrulline and the leucine or metabolite thereof.
