The present invention describes the combination of a NK1-antagonist with pramipexole or a pharmaceutically acceptable salt or solvate thereof, useful for treating depressive disorders, including major depressive disorder.
1. A method for treating a depressive disorder, in a patient, which comprises administering to said patient in need of said treatment an effective daily dose of a NK1-antagonist in combination with an effective daily dose of pramipexole or a pharmaceutically acceptable salt or solvate thereof.
2. The method of claim 1 , wherein said NK1-antagonist effective daily dose in said combination is from 1 μg to 600 mg.
3. The method of claim 1 , wherein said effective daily dose of pramipexole or a pharmaceutically acceptable salt or solvate thereof in said combination is equivalent to from 0.375 mg to 45 mg of pramipexole dihydrochloride monohydrate.
4. The method of claim 1 , wherein said NK1-antagonist in said combination is aprepitant or a pharmaceutically acceptable salt or solvate thereof.
5. The method of claim 1 , wherein said NK1-antagonist in said combination is rolapitant or a pharmaceutically acceptable salt or solvate thereof.
6. The method of claim 1 , wherein said NK1-antagonist in said combination is aprepitant and said pramipexole or a pharmaceutically acceptable salt or solvate thereof in said combination is pramipexole dihydrochloride monohydrate.
7. The method of claim 1 , wherein said NK1-antagonist in said combination is aprepitant, at an effective daily dose of from 10 mg to 250 mg and said pramipexole or pharmaceutically acceptable salt or solvate thereof in said combination is pramipexole dihydrochloride monohydrate, at an effective daily dose in a range selected from the group consisting of from more than 4.5 mg to 45 mg, from 5 mg to 45 mg, from more than 6 mg to 45 mg, from 6.5 mg to 45 mg, from more than 10 mg to 45 mg, or from 15 mg to 45 mg.
8. The method of claim 1 , wherein said NK1-antagonist and said pramipexole or pharmaceutically acceptable salt or solvate thereof in said combination are each formulated in a pharmaceutical composition in dosage unit form comprising, respectively, said NK1-antagonist and said pramipexole or pharmaceutically acceptable salt or solvate thereof, each in admixture with a pharmaceutical carrier or vehicle.
9. The method of claim 1 , wherein said NK1-antagonist and said pramipexole or pharmaceutically acceptable salt or solvate thereof in said combination are each formulated in a pharmaceutical composition in dosage unit form comprising, respectively,
said NK1-antagonist in an amount per unit form of from 1 μg to 600 mg; and
said pramipexole or pharmaceutically acceptable salt or solvate thereof in an amount per unit form equivalent to of from 0.125 mg to 45 mg of pramipexole dihydrochloride monohydrate,
each in admixture with a pharmaceutical carrier or vehicle.
10. The method of claim 1 , wherein said NK1-antagonist and pramipexole or pharmaceutically acceptable salt thereof are co-formulated in a pharmaceutical composition in dosage unit form comprising said NK1-antagonist, in an amount per unit form of from 1 μg to 600 mg, and said pramipexole or pharmaceutically acceptable salts and solvates thereof, in an amount per unit form equivalent to from 0.125 mg to 45 mg of pramipexole dihydrochloride monohydrate, in admixture with a pharmaceutical carrier or vehicle.
