Anti-overingestion abuse deterrent compositions
View Patent ↗Described herein are abuse deterrent oral pharmaceutical compositions, methods for making the same, and methods of treatment using such compositions. In particular, oral pharmaceutical compositions that mitigate the risk of overingestion of one or more active pharmaceutical ingredients are described.
1. An oral pharmaceutical composition comprising:
(a) about 50% to about 70% by mass of glyceryl monolinoleate;
(b) about 2% to 50% by mass ion exchanger;
(c) about 25% to about 40% by mass of a polyethylene oxide having a molecular weight (M v ) of about 1,000,000 to about 7,000,000; and
(d) about 1% to 20% by mass of one or more active pharmaceutical ingredients (API), wherein 15% or about 30% of the API is in a free form and 70% or about 85% of the API is bound to the ion exchanger.
2. The composition of claim 1 , wherein the composition forms an abuse deterrent elastic semi-solid composition after being heated at a temperature of about 50° C. to about 80° C. for a time period of about 10 min to about 180 min and then cooling the composition to room temperature.
3. The composition of claim 1 , wherein a greater quantity of API is adsorbed by the ion exchanger when a plurality of dosage forms are simultaneously ingested or successively ingested over about a 4 hour period.
4. The composition of claim 1 , wherein the plurality of doses is 2 or greater.
5. The composition of claim 1 , wherein the plurality of doses is from 2 to 30.
6. The composition of claim 1 , wherein the portion of API bound to the ion exchanger is about 70%.
7. The composition of claim 1 , wherein the portion of API bound to the ion exchanger is about 85%.
8. The composition of claim 1 , wherein following ingestion of the composition by a subject, the one or more ion exchanger adsorbs a quantity of the one or more API and impedes its release into the subject's systemic circulation.
9. The composition of claim 1 , wherein the API comprises oxycodone or a pharmaceutically acceptable salt thereof.
10. The composition of claim 1 , further comprising:
(a) about 0.1% to about 0.4% by mass of BHA; and
(b) about 0.05% to about 0.1% by mass of BHT.
11. The composition of claim 1 , wherein the composition comprises:
(a) about 50% to about 70% by mass of glyceryl monolinoleate;
(b) about 2% to 50% by mass ion exchanger;
(c) about 25% to about 40% by mass of polyethylene oxide having a molecular weight (M v ) of about 1,000,000 to about 7,000,000;
(d) about 0.05% to about 0.4% by mass of BHA;
(e) about 0.05% to about 0.1% by mass of BHT; and
(f) about 1% to about 20% of by mass of oxycodone hydrochloride.
12. The composition of claim 1 , wherein the composition comprises:
(a) about 1% to about 30% by mass API; and
(b) about 20% to 50% by mass ion exchanger.
13. The composition of claim 1 , wherein the ion exchanger comprises: polystyrene sulfonate or a salt thereof.
14. The composition of claim 1 , wherein the composition comprises:
(a) about 2% to about 10% by mass API; and
(b) about 5% to about 50% by mass ion exchanger.
15. The composition of claim 1 , wherein the composition is capable of achieving one or more of the following pharmacokinetic parameters:
(a) a lower C max for the API as compared to an equivalent API dose lacking an ion exchanger;
(b) a delayed T max for the API as compared to an equivalent API dose lacking an ion exchanger;
(c) a similar plasma AUC for the API as compared to an equivalent API dose lacking an ion exchanger;
(d) an extended absorption time for the API as compared to an equivalent API dose lacking an ion exchanger; or
(e) an extended clearance time for the API as compared to an equivalent API dose lacking an ion exchanger.
16. The composition of claim 1 , wherein the composition exhibits an in vitro disintegration or dissolution rate comprises about 50% after about 120 minutes in simulated gastric fluid (pH 1.2) in an USP Apparatus III.
17. The composition of claim 1 , wherein the composition is a non-layered semi-solid composition.
18. The composition of claim 1 , wherein the API comprises about 5 mg to about 120 mg of oxycodone hydrochloride.
19. The composition of claim 1 , wherein the composition comprises an API to ion exchanger mass ratio of about 1:2 to about 1:5.
20. The composition of claim 1 , wherein the composition comprises an API to ion exchanger mass ratio of about 1:2 to about 1:3.
