Abstract: There is described a device for dispensing a drug or medicament in pellet form. The device includes a cartridge including a chamber for containing a plurality of pellets and a screw pump, wherein the screw pump is configured to receive pellets from the chamber and, upon rotation of the screw pump, transport the pellets from the chamber to be dispensed from the device via the screw pump. The device further includes a rotating member extending through the cartridge and configured to rotate the screw pump so as to dispense pellets therefrom. The cartridge further includes a tapered portion configured to guide pellets contained within the chamber into the screw pump for dispensing from the device via the screw pump as aforesaid. The screw pump is located outside of the tapered portion of the cartridge.

Abstract: This invention relates to compounds having the formula: ##STR1## in which R.sub.1 and R.sub.2 are independently hydrogen, a C.sub.1-4 alkyl group or an aliphatic or aromatic acyl group, provided R.sub.1 and R.sub.2 are not simultaneously hydrogen, or, together with the nitrogen atom to which they are attached, R.sub.1 and R.sub.2 form a 5- or 6-membered ring which may carry another heteroatom; R.sub.3 is a C.sub.1-4 alkyl group; and R.sub.4 and R.sub.5 represent independently a hydrogen or halogen atom, a C.sub.1-4 alkyl group or a C.sub.1-4 alkoxy group; and the acid addition salts of the above compounds. Said new compounds have an anxiolytic and diuretic action, together with a spasmolytic action of non-.alpha.-adrenalytic nature on the unstriated muscle fibers.
