Pharmaceutical composition having modified carrier
View Patent ↗A composition comprising: (a) one to three bioactive agents; and (b) a modified liquid vehicle; wherein immediately after manufacture of the composition, said composition can be administered to a host such that the one to three bioactive agents is released to the host on a sustained basis is provided.
1. A composition comprising:
(a) crystalline ceftiofur free acid; and
(b) a modified liquid vehicle, said vehicle comprising;
i) a modified unsaturated oil having a peroxide value of between about 10 to about 600 milliequivalents (mEq) of peroxide per 1000 grams of oil and optionally,
ii) a saturated oil;
wherein said modified unsaturated oil comprises corn oil, peanut oil, sesame oil, olive oil, palm oil, safflower oil, soybean oil cottonseed oil, rapeseed oil, sunflower oil, a modified oxidizable synthetic oil, or mixtures thereof; wherein said saturated oil comprises coconut oil; wherein the saturated oil may be present at a level such that the ratio of modified unsaturated oil to saturated oil is from about 0.01:99.99 to about 90:10 (v/v).
2. The composition according to claim 1 wherein said modified liquid vehicle comprises a modified unsaturated oil and a saturated oil.
3. The composition according to claim 1 wherein said modified liquid vehicle comprises a mixture of a modified unsaturated oil with either a non-modified saturated oil or a non-modified unsaturated oil.
4. The composition according to claim 1 wherein said modified unsaturated oil comprises modified cottonseed oil.
5. The composition according to claim 1 wherein said modified liquid vehicle is a mixture of modified cottonseed oil and saturated coconut oil.
6. The composition according to claim 1 wherein said modified liquid oil includes a substantially peroxidized unsaturated oil.
7. A composition comprising crystalline ceftiofur free acid, modified cottonseed oil and coconut oil.
8. The composition according to claim 7 wherein the ratio by volume of modified cottonseed oil to coconut oil is between 0.01:99.99 to 30:70.
9. The composition according to claim 8 wherein the ratio by volume of modified cottonseed oil to coconut oil is between 10:90 to 20:80.
10. The composition according to claim 7 wherein the concentration of crystalline ceftiofur free acid in said composition ranges from 50 mg/ml to 250 mg/ml.
11. The composition according to claim 10 wherein the concentration of crystalline ceftiofur free acid in said composition ranges from about 100 mg/ml to about 200 mg/ml.
12. A composition consisting essentially of crystalline ceftiofur free acid, modified cottonseed oil and coconut oil wherein the concentration of crystalline ceftiofur free acid in said composition ranges from about 100 mg/ml to about 200 mg/ml and the ratio by volume of modified cottonseed oil to coconut oil is between about 10:90 to about 20:80.
13. A composition comprising:
(a) crystalline ceftiofur free acid; and
(b) a modified liquid vehicle, said vehicle comprising;
i) a modified unsaturated oil comprising a substantially peroxidized unsaturated oil having a peroxide value of between about 10 to about 600 milliequivalents (mEq) of peroxide per 1000 grams of oil and,
ii) a saturated oil
wherein the unsaturated oil is modified before it is combined with the saturated oil to form a modified liquid vehicle.
