Therapeutic methods using bupropion hydrobromide to treat Major Depressive Disorder
View Patent ↗Disclosed are methods of treating a patient having Major Depressive Disorder (MDD). The methods include administering to the patient a therapeutically effective amount of bupropion hydrobromide in extended-release form. The methods are more therapeutically effective in treating MDD than administration of an equivalent plasma dose of bupropion hydrochloride in extended-release form. Optionally, in addition, the therapeutically effective amount of bupropion hydrobromide reduces the incidence of one or more adverse events (anxiety, agitation and/or insomnia), when compared to the administration of the equivalent plasma dose of bupropion hydrochloride in extended-release form.
1. A method of treating a patient having Major Depressive Disorder (MDD), the method comprising:
selecting a MDD patient who previously tried bupropion hydrochloride in extended-release form at an adequate plasma dose for an adequate duration in a current depressive episode and experienced an inadequate therapeutic response; and
administering to the patient a therapeutically effective amount of bupropion hydrobromide in extended-release form, wherein the bupropion hydrobromide in extended-release form is more therapeutically effective in treating MDD in the patient than administration of an equivalent plasma dose of bupropion hydrochloride in extended-release form.
2. The method of claim 1 , wherein the therapeutically effective amount of bupropion hydrobromide in extended-release form is 174 mg of bupropion hydrobromide and the equivalent plasma dose of bupropion hydrochloride in extended-release form is 150 mg of bupropion hydrochloride.
3. The method of claim 1 , wherein the therapeutically effective amount of bupropion hydrobromide in extended-release form is 348 mg of bupropion hydrobromide and the equivalent plasma dose of bupropion hydrochloride in extended-release form is 300 mg of bupropion hydrochloride.
4. The method of claim 1 , wherein the therapeutically effective amount of bupropion hydrobromide in extended-release form is 522 mg of bupropion hydrobromide and the equivalent plasma dose of bupropion hydrochloride in extended-release form is 450 mg of bupropion hydrochloride.
5. The method of claim 1 , wherein the therapeutically effective amount of bupropion hydrobromide in extended-release form is from 150 mg to 800 mg of bupropion hydrobromide and the equivalent plasma dose of bupropion hydrochloride in extended-release form is from 84 to 88% of the dose of the therapeutically effective amount of bupropion hydrobromide.
6. The method of claim 5 , wherein the equivalent plasma dose of bupropion hydrochloride in extended-release form is about 86.2% of the dose of the therapeutically effective amount of bupropion hydrobromide.
7. The method of claim 1 , wherein the method is adjunctive to administration of a second drug to treat the patient.
8. The method of claim 1 , wherein the patient previously tried and failed at least one selective serotonin reuptake inhibitor (SSRI) or serotonin and norepinephrine reuptake inhibitor (SNRI) that had been administered for adequate dose and duration or that had been discontinued due to side effects.
9. The method of claim 6 , wherein the patient who previously tried bupropion hydrochloride in extended-release form experienced one or more side effects selected from the group consisting of anxiety, agitation and insomnia and wherein the one or more side effects were reduced or ameliorated when the patient was administered the therapeutically effective amount of bupropion hydrobromide in extended-release form.
10. A method of treating a patient having Major Depressive Disorder (MDD), the method comprising:
selecting a MDD patient that previously tried bupropion hydrochloride in extended-release form at an adequate plasma dose for an adequate duration in a current depressive episode and experienced an inadequate therapeutic response and side effects; and
administering to the patient a therapeutically effective amount of bupropion hydrobromide in extended-release form, wherein the bupropion hydrobromide in extended-release form is more therapeutically effective in treating MDD than administration of an equivalent plasma dose of bupropion hydrochloride in extended-release form, and wherein the therapeutically effective amount of bupropion hydrobromide reduces or ameliorates one or more side effects selected from the group consisting of anxiety, agitation and insomnia, when compared to administration of the equivalent plasma dose of bupropion hydrochloride in extended-release form.
11. The method of claim 10 , wherein the therapeutically effective amount of bupropion hydrobromide in extended-release form is from 150 mg to 800 mg of bupropion hydrobromide and the equivalent plasma dose of bupropion hydrochloride in extended-release form is from 84 to 88% of the dose of the therapeutically effective amount of bupropion hydrobromide.
12. The method of claim 10 , wherein the method is adjunctive to administration of a second drug to treat the patient.
