Abstract

A method of administering small, bioadhesive drug tablets includes moving an end portion of a delivery member. A surface of the delivery member can be positioned to prevent movement of the drug tablet from a tablet cartridge channel to a delivery passage of a delivery device when the end portion of the delivery member is in a first stopped position. The end portion of the delivery member can be moved to a second position within the delivery passage such that the tablet cartridge channel is in communication with the delivery passage. The drug tablet can be conveyed into the delivery passage via the tablet cartridge channel. The end portion of the delivery member can be moved to a third position within the delivery passage to convey the drug tablet through an exit opening of the delivery device.
