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; R1 represents —(CO)xC1-9 alkyl or —(CO)xC1-9 fluoroalkyl, which fluoroalkyl moiety contains at least 1 fluorine atom and not more than 3 consecutive perfluorocarbon atoms wherein x represents 0 or 1; and R2 and R3 independently represent C1-3alkyl or hydrogen, (ii) at least one medicament, and (iii) at least one propellant.

Abstract: The present invention relates to an improved analytical method and apparatus therefor, in particular to a method and apparatus for continuous titration in which at least one parameter of at least one compound in a test mixture may be monitored as the composition of the mixture is continuously varied. The method comprises the steps of continuously mixing at least two component fluid streams to form a test mixture stream and passing the test mixture stream through a spectrophotometric detection zone, with the volume to volume ratio of at least two of the component streams forming the test mixture stream continuously and linearly varied with time by alteration of the relative proportions of the component streams forming the test mixture, while the total volume of the test mixture stream remains constant.

Abstract: There are provided according to the invention compounds of the formula (I) or a salt or solvate thereof, wherein: n represents an integer 1 to 6; N represents an integer 1 to 15; R1 represents (CO)xC1-9alkyl or (CO)xC1-9fluoroalkyl, which fluoroalkyl moiety contains at least 1 fluorine atom and not more than 3 consecutive perfluorocarbon atoms wherein x represents 0 or 1; and R2 and R3 independently represent C1-3alkyl or hydrogen. There are also provided pharmaceutical aerosol formulations employing said compounds as suspension stabilising agents.
