Abstract

Compositions and methods for making robust pellets that contain a high percentage, by weight, of active drug agent, and which also contain additional components that enhance the absorption and solubility of the active drug agent within the gastrointestinal tract (GI tract) without diminishing the robust nature of the pellet, are disclosed.

Claims (16)

1. A pharmaceutical pellet comprising a granulated mixture, wherein the granulated mixture comprises at least one active ingredient drug component, at least one pharmaceutically acceptable absorption enhancing agent, wherein said at least one pharmaceutically acceptable absorption enhancing agent is selected from the group consisting of: non ionic surfactants, hydrophilic surfactants, hydrophobic surfactants, short chain fatty acids, long chain fatty acids, short chain triglycerides, and long chain triglycerides, and at least one pharmaceutically acceptable solubility enhancing agent, wherein said at least one pharmaceutically acceptable solubility enhancing agent is selected from the group consisting of: Methyl-2 Pyrrolidone, diethylene glycol monoethyl ether, and pharmaceutically accepted alcohols; wherein said at least one active ingredient drug component comprises at least one beta lactam penicillin and constitutes at least 50% W/W of said pharmaceutical pellet, wherein said at least one pharmaceutically acceptable absorption enhancing agent constitutes 2 to 10% W/W of said pharmaceutical pellet; wherein said at least one pharmaceutically acceptable solubility enhancing agent is a solvent for said at least one active ingredient drug component.

2. The pharmaceutical pellet of claim 1 , wherein said at least one active ingredient drag component is Amoxicillin present in an amount of from 70-90% W/W of said pharmaceutical pellet, wherein said at least one pharmaceutically acceptable absorption enhancing agent is Caprylocaproyl Macrogogol-6 Glycerides present in an amount of from 2-10% W/W of said pharmaceutical pellet, and wherein said at least one pharmaceutically acceptable solubility enhancing agent is Methyl-2 Pyrrolidone present in an amount of 2-10% W/W of said pharmaceutical pellet.

3. The pharmaceutical pellet of claim 1 , wherein said active drug component is Amoxicillin.

4. The pharmaceutical pellet of claim 1 , wherein said Beta-Lactam Penicillin is selected from the group consisting of Amoxicillin, Penicillin, and Dicloxicillin.

5. A pharmaceutical pellet comprising a granulated mixture, wherein the granulated mixture comprises: at least one active ingredient drug component comprising at least one beta lactam penicillin, at least one pharmaceutically acceptable absorption enhancing agent, and at least one pharmaceutically acceptable solubility enhancing agent, wherein said at least one pharmaceutical acceptable solubility enhancing agent is selected from the group consist of: Methyl-2 Pyrrolidone, diethylene glycol monoethyl ether, and pharmaceutically accepted alcohols; wherein said at least one active ingredient drug component constitutes at least 50% W/W of said pharmaceutical pellet, wherein said at least one pharmaceutically acceptable absorption enhancing agent is a surfactant triglyceride; wherein said at least one pharmaceutically acceptable solubility enhancing agent is a solvent for said at least one active ingredient drug component; wherein said at least one pharmaceutically acceptable absorption enhancing agent constitutes 2 to 10% W/W of said pharmaceutical pellet; wherein said at least one pharmaceutically acceptable solubility enhancing agent constitutes 2 to 10% W/W of said pharmaceutical pellet.

6. The pharmaceutical pellet of claim 5 , wherein the triglyceride is a caprylic/capric glyceride.

7. The pharmaceutical pellet of claim 5 , wherein said beta-lactam penicillin is selected from the group consisting of Amoxicillin, Penicillin, and Dicloxicillin.

8. The pharmaceutical pellet of claim 7 , wherein said beta-lactam penicillin is Amoxicillin and is present in an amount of from 70-90% W/W of said pharmaceutical pellet.

9. The pharmaceutical pellet of claim 5 , wherein said at least one pharmaceutically acceptable solubility enhancing agent is Methyl-2 Pyrrolidone or diethylene glycol monoethyl ether and said beta-lactam penicillin is Amoxicillin and said Amoxicillin is present in an amount of from 70-90% W/W of said pharmaceutical pellet.

10. The pharmaceutical pellet of claim 1 , wherein said at least one pharmaceutically acceptable solubility enhancing agent constitutes 2 to 10% W/W of said pharmaceutical pellet.

11. The pharmaceutical pellet of claim 10 , wherein said at least one pharmaceutically acceptable solubility enhancing agent is Methyl-2 Pyrrolidone or diethylene glycol monoethyl ether and said at least one pharmaceutically acceptable absorption enhancing agent is an alkoxylate or a caprylocaproyl macrogogol-6 glyceride.

12. The pharmaceutical pellet of claim 11 , wherein said beta-lactam penicillin is selected from the group consisting of Amoxicillin, Penicillin, and Dicloxicillin.

13. The pharmaceutical pellet of claim 12 , wherein said beta lactam penicillin is Amoxicillin and is present in an amount of from 70-90% W/W of said pharmaceutical pellet.

14. The pharmaceutical pellet of claim 13 , wherein said at least one pharmaceutically acceptable solubility enhancing agent is Methyl-2 Pyrrolidone and said at least one pharmaceutically acceptable absorption enhancing agent is caprylocaproyl macrogogol-6 glyceride.

15. The pharmaceutical pellet of claim 10 , wherein said beta-lactam penicillin is Amoxicillin.

16. The pharmaceutical pellet of claim 5 , wherein said beta-lactam penicillin is Amoxicillin.
