Multiple unit dosage form having a therapeutic agent in combination with a nutritional supplement
Compositions and methods for combination therapy are provided. The compositions comprise a multiple unit dosage form having both a therapeutic agent and a nutritional supplement. The combination therapy is useful for restoring a nutrient depletion associated with a particular disease state. Additionally, the combination therapy can prevent or attenuate the depletion of a nutrient caused, in whole or in part, by the co-administrated therapeutic drug. Methods of manufacturing the formulations are likewise described.
1. A dosage form for oral administration comprising:
an inner therapeutic agent;
a middle barrier layer disposed over the therapeutic agent, wherein the therapeutic agent is selected from anxiolytics, anticonvulsants, antiemetics, hormonal contraceptives, selective estrogen receptor modulators, and fertility agents, or combinations thereof; and
an outer nutritional supplement layer disposed over the barrier layer, wherein the nutritional supplement is a vitamin, a mineral, or a combination thereof;
wherein said inner therapeutic agent and outer nutritional supplement layer are formulated as a single dose.
2. The dosage form of claim 1 , wherein the therapeutic agent further comprises one or more of analgesics, anesthetics, bronchodilators, decongestants, anti-proliferatives, antibiotics, anti-virals, chemotherapeutics, immuno-suppressants, and anti-pruritics, or combinations thereof.
3. The dosage form of claim 2 , wherein the therapeutic agent is provided in a therapeutically effective amount.
4. The dosage form of claim 1 , wherein the therapeutic agent is selected from anxiolytics, hormonal contraceptives, and fertility agents, or combinations thereof.
5. The dosage form of claim 4 , wherein the therapeutic agent is selected from hormonal contraceptives and fertility agents.
6. The dosage form of claim 5 , wherein the therapeutic agent is one or more hormonal contraceptives.
7. The dosage form of claim 5 , wherein the therapeutic agent is one or more fertility agents.
8. The dosage form of claim 1 , wherein the barrier layer is comprised of a controlled-release, delayed-release, or enteric coating.
9. The dosage form of claim 1 , wherein the nutritional supplement is provided in a therapeutically effective amount.
10. The dosage form of claim 1 , wherein the nutritional supplement is selected from the group consisting of biotin, choline, folate, niacin, pantothenic acid, riboflavin, thiamine, vitamin A, vitamin B6, vitamin B12, vitamin C, vitamin E, bromine, cobalt, copper, fluorine, germanium, iodine, iron, magnesium, manganese, molybdenum, potassium, selenium, silicon, zinc, calcium, phosphorous, sodium, sulfur, and vanadium, or combinations thereof.
11. A method of preventing and/or attenuating depletion of a nutrient caused by the co-administration of a therapeutic agent to an individual in need thereof, comprising:
identifying an individual presenting with nutrient depletion associated with the administration of a therapeutic agent; and
administering to the individual the dosage form of claim 1 , wherein said therapeutic agent causes or exacerbates nutrient depletion, wherein said nutritional supplement prevents and/or attenuates said depletion; and wherein said nutrient is selected from the group consisting of biotin, choline, folate, niacin, pantothenic acid, riboflavin, thiamine, vitamin A, vitamin B6, vitamin B12, vitamin C, vitamin E, bromine, cobalt, copper, fluorine, germanium, iodine, iron, magnesium, manganese, molybdenum, potassium, selenium, silicon, zinc, calcium, phosphorous, sodium, sulfur, and vanadium, or combinations thereof.
12. The method of claim 11 , wherein said therapeutic agent is selected from anxiolytics, anticonvulsants, antiemetics, hormonal contraceptives, selective estrogen receptor modulators, and fertility agents, or combinations thereof.
13. The method of claim 11 , wherein said therapeutic agent is selected from anxiolytics, hormonal contraceptives, and fertility agents, or combinations thereof.
14. The method of claim 11 , wherein said therapeutic agent is selected from hormonal contraceptives and fertility agents.
15. The method of claim 11 , wherein said therapeutic agent is one or more hormonal contraceptives.
16. The method of claim 11 , wherein said therapeutic agent is one or more fertility agents.
17. The method of claim 11 , wherein said nutritional supplement prevents said nutrient depletion.
18. The method of claim 11 , wherein said nutritional supplement attenuates said nutrient depletion.
19. A method of synergistically treating a disease or condition caused or exacerbated by nutrient depletion comprising administering to an individual in need thereof the dosage form of claim 1 , wherein the disease or condition is selected from cardiovascular disease, stroke, cardiovascular lesions, aterial and myocardial lesions, cardiac arrhythmias, depletion of selenium, cardiomyopathy resulting from selenium depletion, depletion of co-enzyme Q10 caused by statin drug therapy, and combinations thereof.
