Alcohol Resistant Pharmaceutical Formulations
The present invention provides alcohol resistant oral dosage pharmaceutical forms and methods of using such oral dosage forms to avoid dose dumping if the dosage form is taken together with alcohol.
1 . A modified release oral dosage form, comprising
(a) a therapeutic agent and;
(b) an alcohol insoluble coating,
wherein between 0% and 35% of the therapeutic agent is released from the dosage form in vitro after 60 minutes in the presence of 40% alcohol at pH 1.2.
2 . The modified release oral dosage form of claim 1 , wherein between 0% and 20% of the therapeutic agent is released from the dosage form in vitro after 60 minutes in the presence of 40% alcohol at pH 1.2.
3 . The modified release oral dosage form of claim 1 , wherein between 0% and 10% of the therapeutic agent is released from the dosage form in vitro after 60 minutes in the presence of 40% alcohol at pH 1.2.
4 . The modified release oral dosage form of claim 1 , wherein the modified release comprises extended release.
5 . The modified release oral dosage form of claim 1 , wherein the modified release comprises delayed release.
6 . The modified release oral dosage form of claim 1 , wherein the alcohol insoluble coating is water insoluble.
7 . The modified release oral dosage form of claim 1 , wherein the alcohol insoluble coating comprises one or more compounds listed in Table 1.
8 . The modified release oral dosage form of claim 1 , wherein the modified release oral dosage comprises a tablet.
9 . The modified release oral dosage form of claim 1 , wherein the modified release oral dosage comprises a capsule.
10 . The modified release oral dosage form of claim 1 , wherein the alcohol insoluble coating comprises a 1% to 40% weight gain in the oral dosage form.
11 . The modified release oral dosage form of claim 1 , wherein the alcohol insoluble coating is between 5 microns thick and 1000 microns thick.
12 . The modified release oral dosage form of claim 1 , wherein the therapeutic comprises an analgesic, or a pharmaceutically acceptable salt thereof.
13 . The modified release oral dosage form of claim 1 , wherein the analgesic comprises an opioid analgesic, or a pharmaceutically acceptable salt thereof.
14 . The modified release oral dosage form of claim 13 , wherein the therapeutic further comprises a non-opioid drug.
15 . A method for alleviating pain, comprising administering to an individual in need thereof an amount effective to alleviate pain of the oral dosage form of claim 12 .
16 . A method for alleviating pain, comprising administering to an individual in need thereof an amount effective to alleviate pain of the oral dosage form of claim 13 .
17 . A method for alleviating pain, comprising administering to an individual in need thereof an amount effective to alleviate pain of the oral dosage form of claim 14 .
18 . The method of claim 15 , wherein the individual in need thereof drinks alcoholic beverages or is otherwise exposed to alcohol.
19 . The method of claim 16 , wherein the individual in need thereof drinks alcoholic beverages or is otherwise exposed to alcohol.
20 . The method of claim 17 , wherein the individual in need thereof drinks alcoholic beverages or is otherwise exposed to alcohol.
