ABSTRACT:
A method for treating respiratory disorders comprises administering to a patient a pharmaceutical aerosol formulation comprising: (i) a compound of formula (I)or a salt or solvate thereof, wherein:n represents an integer 1 to 6;N represents an integer 1 to 15;R1represents —(CO)xC1-9alkyl or —(CO)xC1-9fluoroalkyl, which fluoroalkyl moiety contains at least 1 fluorine atom and not more than 3 consecutive perfluorocarbon atomswherein x represents 0 or 1; andR2and R3independently represent C1-3alkyl or hydrogen, (ii) at least one medicament, and (iii) at least one propellant.
