Eutectic-based self-nanoemulsified drug delivery system
View Patent ↗A eutectic-based self-nanoemulsified drug delivery system (SNEDDS) is formulated from polyoxyl 35 castor oil (Cremophor), medium chain mono- and diglycerides (capmul), essential oils, and a pharmacologically effective drug or nutraceutical or dietary supplement. The preferred pharmacologically effective drug is a poorly water soluble drug, such as ubiquinone (CoQ 10 ). The SNEDDS can be further incorporated into a powder to produce a solid dosage form. The solid dosage form contains the SNEDDS, a copolymer of vinylpyrrolidone and vinyl acetate (Kollidon VA 64), maltodextrin, and microcrystalline cellulose (MCC).
1. An orally administered dietary supplement including a eutectic-based delivery system, comprising:
a) ubiquinone; and
b) a sufficient amount of a volatile essential oil to solubilize the ubiquinone, and wherein said volatile essential oil is present in a sufficient amount to reduce the melting point of ubiquinone to 37° C. or below, and thereby solubilize the ubiquinone comprised in the orally administered dietary supplement at or below body temperature.
2. The orally administered dietary supplement of claim 1 , wherein said volatile essential oil is selected from the group consisting of menthol, spearmint oil, peppermint oil, lemon oil, anise oil, and mixtures thereof.
3. The orally administered dietary supplement of claim 1 , further comprising a surfactant.
4. A delivery system for pharmacologically effective agents, comprising:
a) ubiquinone;
b) a surfactant;
c) a sufficient amount of a volatile essential oil to reduce the melting point of ubiquinone to 37° C. or below, and thereby solubilize the ubiquinone comprised in the delivery system at or below body temperature.
5. The eutectic-based delivery system of claim 4 , wherein said volatile essential oil is selected from the group consisting of menthol, spearmint oil, peppermint oil, lemon oil, anise oil, and mixtures thereof.
6. The eutectic-based delivery system of claim 5 , wherein said essential oil is lemon oil.
7. The eutectic-based delivery system of claim 4 , wherein said surfactant is polyoxyl 35 caster oil or a medium chain mono- and diglyceride.
8. The orally administered dietary supplement of claim 1 , wherein the dietary supplement composition is contained in a capsule.
9. The eutectic-based delivery system of claim 4 , wherein the delivery system is contained in a capsule.
10. An orally administered dietary supplement including a eutectic-based delivery system, comprising
a) ubiquinone; and
b) a sufficient amount of a volatile essential oil to solubilize the ubiquinone, and wherein said volatile essential oil is present in a sufficient amount to reduce the melting point of ubiquinone to 37° C. or below, and thereby solubilize the ubiquinone comprised in the orally administered dietary supplement at or below body temperature; and
c) wherein the dietary supplement composition is contained within a capsule.
11. The orally administered dietary supplement of claim 10 , wherein the capsule is a hard capsule.
12. The orally administered dietary supplement of claim 10 , wherein the capsule is a soft capsule.
13. The orally administered dietary supplement of claim 1 , wherein the amount of the volatile essential oil is sufficient to solubilize the ubiquinone after ingestion by a patient.
