| Patent Claims: |
1. A pharmaceutical composition comprising: (i) budesonide in an amount of about 0.1 mg to about 10 mg per unit dose of the composition; (ii) ethylenediaminetetraacetic acid, ascorbyl palmitate, sodium ascorbate, or a combination of two or more thereof; (iii) about 50 mg/mL to about 600 mg/mL of maltodextrin; and (iv) an aqueous liquid vehicle; wherein the composition is an oral liquid suspension suitable for oral administration, and wherein the composition has a viscosity of greater than 2 cP at 25° C. and a shear rate of about 13.2 sec-1. 2. The composition of claim 1, wherein (ii) is ethylenediaminetetraacetic acid. 3. The composition of claim 1, wherein (ii) is sodium ascorbate. 4. The composition of claim 1, wherein the composition has a viscosity of about 50 cP or greater at 25° C. and a shear rate of about 13.2 sec-1. 5. The composition of claim 1, wherein the composition has a viscosity of about 200 cP at 25° C. and a shear rate of about 13.2 sec-1. 6. The composition of claim 1, wherein the composition is thixotropic. 7. The composition of claim 1, wherein the composition has a volume of about 2 mL to about 20 mL. 8. The composition of claim 1, comprising budesonide in an amount from about 0.25 mg to about 5 mg per unit dose of the composition. 9. The composition of claim 1, wherein (i) is budesonide microparticles; and wherein at least 95% of the budesonide microparticles have a diameter of less than 10 microns. 10. A pharmaceutical composition comprising: (i) budesonide in an amount of about 0.1 mg to about 10 mg per unit dose of the composition; (ii) about 50 mg/mL to about 600 mg/mL of maltodextrin; and (iii) an aqueous liquid vehicle; wherein the composition is an oral liquid suspension suitable for oral administration, and wherein the composition has a viscosity of greater than 2 cP at 25° C. and a shear rate of about 13.2 sec -1. 11. The composition of claim 1, wherein the composition has a viscosity of about 25 cP to about 800 cP at 25° C. and a shear rate of about 13.2 sec-1. 12. The composition of claim 10, wherein the composition has a viscosity of about 25 cP to about 800 cP at 25° C. and a shear rate of about 13.2 sec-1. 13. The composition of claim 10, wherein the composition has a volume of about 2 mL to about 20 mL. 14. The composition of claim 10, comprising budesonide in an amount from about 0.25 mg to about 5 mg per unit dose of the composition. 15. The composition of claim 10, comprising about 200 mg/mL to about 400 mg/mL of maltodextrin. |
