Abstract
Compositions containing β2 adrenergic agonists in combination with carbonates and carbamates of the formula and in combination with related steroid carbonates and carbamates are disclosed. The compositions are useful for treating bronchospasm, for inducing bronchodilation and for treating rhinitis, asthma, and chronic obstructive pulmonary disease (COPD) and inflammatory diseases, particularly by inhalation.

A composition comprising a β2 adrenergic agonist in combination with a compound of Formula I:
- wherein
- R1 and R2, independently for each occurrence, represent a hydrogen, lower alkyl or lower acyl, or taken together R1 and R2 form a substituted or unsubstituted ketal;
- R3 is —OR4 or —NR5R6;

- R5 is hydrogen or C7 to C24 hydrocarbon;
- R6 is chosen from C7 to C24 hydrocarbon and —(C7 to C24 hydrocarbon)-COOH;
- R9 is hydrogen or C1 to C17 hydrocarbon;
- R10 is hydrogen or C1 to C17 hydrocarbon;
- R11 is methyl or —OR2;
- and
- X and Y are independently hydrogen or halogen.
