Coenzyme Q compositions persisting in blood
View Patent ↗The object of the present invention is to provide a composition maintaining a blood coenzyme Q concentration at a high level in blood for a prolonged period of time, in order to surely attain an effect of coenzyme Q, which can be expected to manifest a superior effect in maintaining health in humans and animals. By using a composition which comprises a coenzyme Q being a mixture of a reduced coenzyme Q and an oxidized coenzyme Q with the proportion of the reduced coenzyme Q to the whole coenzyme Q of more than 95% by weight, the present invention can attain a high maximum blood concentration of a coenzyme Q as well as long maintenance of high concentration of coenzyme Q in blood for a prolonged period of time, and the area under the blood concentration curve (AUC) can be expanded.
1. A coenzyme Q composition for maintaining high concentration of coenzyme Q in blood
which comprises, as the active ingredients, a reduced coenzyme Q represented by the following formula (1), wherein n represents an integer of 1 to 12, and an oxidized coenzyme Q represented by the following formula (2), wherein n represents an integer of 1 to 12, with the proportion of the reduced coenzyme Q to the whole coenzyme Q of more than 95% by weight
2. The coenzyme Q composition for maintaining high concentration of coenzyme Q in blood according to claim 1 ,
wherein the coenzyme Q is coenzyme Q 10 .
3. coenzyme Q composition for maintaining high concentration of coenzyme Q in blood according to claim 1
which further comprises an antioxidant substance and/or an antioxidant enzyme.
4. The coenzyme Q composition for maintaining high concentration of coenzyme Q in blood according to claim 3 ,
wherein said antioxidant substance is at least one member selected from the group consisting of vitamin E, a vitamin E derivative, vitamin C, a vitamin C derivative, probucol, lycopene, vitamin A, a carotenoid, vitamin B, a vitamin B derivative, a flavonoid, a polyphenol, glutathione, pyrroloquinoline quinone, Pycnogenol, Flavangenol, selenium, a lipoic acid and a lipoic acid derivative.
5. The coenzyme Q composition for maintaining high concentration of coenzyme Q in blood according to claim 3 ,
wherein said antioxidant enzyme is at least one member selected from the group consisting of superoxide dismutase, glutathione peroxidase, glutathione-S-transferase, glutathione reductase, catalase and ascorbic acid peroxidase.
6. A method of maintaining the blood coenzyme Q concentration for a prolonged period of time
which comprises administering a composition comprising a reduced coenzyme Q represented by the following formula (1), wherein n represents an integer of 1 to 12, and an oxidized coenzyme Q represented by the following formula (2), wherein n represents an integer of 1 to 12, with the proportion of the reduced coenzyme Q to the whole coenzyme Q of more than 95% by weight
7. The method according to claim 6 ,
wherein the dosage form of said composition is an oral formulation.
8. The method according to claim 7 ,
wherein said oral formulation is in the form of capsules, tablets, a powder or a liquid.
9. The method according to claim 6 ,
wherein the coenzyme Q is coenzyme Q 10 .
10. The method according to claim 6 ,
by which the blood coenzyme Q concentration can be maintained at levels not lower than half the maximum blood concentration shown after administration of said composition for at least 8 hours.
11. The coenzyme Q composition for maintaining high concentration of coenzyme Q in blood according to claim 2
which further comprises an antioxidant substance and/or an antioxidant enzyme.
12. The method according to any one of claims 7 ,
wherein the coenzyme Q is coenzyme Q 10 .
13. The method according to any one of claims 8 ,
wherein the coenzyme Q is coenzyme Q 10 .
14. The method according to claim 9 ,
by which the blood coenzyme Q 10 concentration can be maintained at levels not lower than half the maximum blood concentration shown after administration of said composition for at least 8 hours.
15. The method according to claim 10 ,
wherein the dosage form of said composition is an oral formulation.
16. The method according to claim 15 ,
wherein said oral formulation is in the form of capsules, tablets, a powder or a liquid.
