A powder inhalation device comprising a housing containing a pharmacologically active compound, a conduit (8) with an outlet extending into the housing through which a user can inhale to create an airflow through the conduit, a dosing unit (6,7) for delivering a dose of the compound to the conduit and baffles (9) arranged within the said conduit to aid disintegration of powder agglomerates entrained in said airflow. The baffles (9) comprise a plurality of staggered plates extending into the conduit from opposite sides of the conduit at an angle of less than 90.degree. to the sides of the conduit and are inclined towards the outlet to create a plurality of constrictions within the conduit and a plurality of changes in the direction of the said airflow through the conduit.
An inhalation device comprising a housing, an outlet through which a user can inhale, a medicament holder defining a pocket for containing a single dose of medicament in the form of a powder, a closure member having a closure pad resiliently urged into contact with the medicament holder to close said pocket, the closure pad and holder acting to contain the medicament, means for moving the pocket into registration with the outlet and means for lifting the closure pad away from the medicament holder to open the pocket when the pocket is brought into registration with the outlet, wherein the rotation of the medicament holder causes the closure pad to be lifted away from the medicament holder.
