Bupropion dosage forms with reduced food and alcohol dosing effects
This disclosure relates to dosage forms comprising bupropion hydrochloride, another salt form of bupropion, or the free base form of bupropion; dextromethorphan hydrobromide, another salt form of dextromethorphan, or the free base form of dextromethorphan, and a polymer. In some embodiments, the dosage form has no significant dose dumping of bupropion in the presence of ethanol in vitro. In some embodiments, the dosage form does not have a food effect for bupropion or dextromethorphan when taken with a high-fat meal in human subjects. Some embodiments include a method of treating a nervous system condition (such as depression, e.g., major depressive disorder, including treatment-resistant depression, agitation associated with Alzheimer's disease (or agitation associated with dementia of the Alzheimer's type), agitation associated with dementia, anxiety (or generalized anxiety disorder), neuropathic pain, or peripheral diabetic neuropathic pain) comprising, administering a dosage form described herein to a human being in need thereof.
1. A method of avoiding seizures during treatment of major depressive disorder in a human patient in need thereof, comprising: 1) selecting a human patient with major depressive disorder who is consuming alcohol; 2) administering a dosage form twice a day to the human patientto avoid seizures; and 3) advising the human patient to minimize, but not abruptly discontinue, alcohol consumption;
wherein the dosage form comprises 105 mg of bupropion hydrochloride, or a molar equivalent amount of another salt form of bupropion or the free base form of bupropion, 45 mg of dextromethorphan hydrobromide, or a molar equivalent amount of another salt form of dextromethorphan or the free base form of dextromethorphan, and a polymer;
wherein the human patient minimizes, but does not abruptly discontinue, alcohol consumption;
wherein if the human patient is an adult male, the human patient consumes two servings or less of alcohol per day after the human patient is advised to minimize alcohol consumption; and
wherein if the human patient is an adult female, the human patient consumes one serving or less of alcohol per day after the human patient is advised to minimize alcohol consumption.
2. The method of claim 1 , wherein the dosage form further comprises colloidal silicon dioxide.

7. The method of claim 1 , wherein the dosage form further comprises microcrystalline cellulose.
8. The method of claim 1 , wherein the dosage form further comprises polyvinyl alcohol.
9. The method of claim 1 , wherein the dosage form further comprises sodium lauryl sulfate.
10. The method of claim 1 , wherein the dosage form further comprises stearic acid.
11. The method of claim 1 , wherein the dosage form further comprises titanium dioxide.
12. The method of claim 1 , wherein the polymer is a carbomer homopolymer.
13. The method of claim 1 , wherein the dosage form further comprises: colloidal silicon dioxide, crospovidone, glyceryl monocaprylocaprate, L-cysteine hydrochloride monohydrate, magnesium stearate, microcrystalline cellulose, polyvinyl alcohol, red iron oxide, sodium lauryl sulfate, stearic acid, talc, titanium dioxide, or yellow iron oxide, or a combination thereof.
