Abstract: A nebuliser comprises an outlet aperture and a liquid capillary. A method of operating the nebuliser comprises supplying a gas to the outlet aperture, measuring a flow rate of the gas supplied to the outlet aperture, and determining a position of the liquid capillary relative to the outlet aperture based on the measured flow rate.

Abstract: The present invention provides pharmaceutical compositions which include (?)-pseudoephedrine and a pharmaceutically acceptable carrier, wherein the (?)-pseudoephedrine is substantially-free of (+)-pseudoephedrine. In another embodiment, the present invention provides methods of relieving nasal and bronchial congestion and of inducing pupil dilation which include administering a pharmaceutically effective amount of (?)-pseudoephedrine to a mammal. The (?)-pseudoephedrine used in the present methods is substantially free of (+)-pseudoephedrine and also substantially free of side effects caused by administration of (+)-pseudoephedrine.

Abstract: The present invention provides stereoscopically-pure diastereomers of Formula I: In a preferred embodiment, the stereoisomers of the present invention are of Formula II, depicted below: R2, R3 and R4 are independently H, OH, OCH3, CH2OH, NHCONH2, NH2, halogen or CF3, and R1 is pyridine, or an amine which may be substituted with hydrogen, lower alkyl, lower alkylenearyl, lower alkylenephenyl, lower alkylenehydroxyphenyl, lower alkyleneamine, lower alkyleneaminoaryl, lower alkylaminohydroxyphenyl, or a similar functional group. R5 is hydrogen, hydroxyl or methyl; R6 is hydrogen, lower alkyl, lower alkylenaryl, lower alkylenephenyl, lower alkylenehydroxyphenyl, lower alkyleneamine, lower alkyleneaminoaryl, lower alkylaminohydroxyphenyl, and the like. For both Formula I and Formual II, the first carbon on the side chain progressing from the ring is preferably in the R-configuration. The second carbon atom on the side chain of Formula II, which is attached to R5, may or may not be a chiral center.

Abstract: The present invention provides pharmaceutical compositions which include (−)-pseudoephedrine and a pharmaceutically acceptable carrier, wherein the (−)-pseudoephedrine is substantially-free of (+)-pseudoephedrine. In another embodiment, the present invention provides methods of relieving nasal and bronchial congestion and of inducing pupil dilation which include administering a pharmaceutically effective amount of (−)-pseudoephedrine to a mammal. The (−)-pseudoephedrine used in the present methods is substantially free of (+)-pseudoephedrine and also substantially free of side effects caused by administration of (+)-pseudoephedrine.

Abstract: The present invention relates to methods of using and compositions containing acrivastine which provide antihistaminic therapeutic benefits while minimizing undesirable central nervous system side effects. According to the present invention, the plasma concentration-response curve for acrivastine's sedative side effects is steeper than that of the plasma concentration-response curve for its antihistamine activity. Accordingly, when the peak blood plasma level of acrivastine is maintained within the levels provided by the present invention composition, the central nervous side effects are minimized while the antihistaminic effects are optimized.

Abstract: An aircraft cargo container (10) is provided with one or more expandable regions for expansion under blast loading thereby to absorb a portion of the blast energy from a blast within the container (10). The absorbing means may comprise corrugated or concertina shaped sheets (20, 22, 34) which expand under blast loading and together with a blast absorbing material (24). The sheets (20, 22, 34) and material (24) may be provided in one or more panels (12, 14) and/or at one or more edged if required.
