A drug dispensing assembly for dispensing solid drug delivery vessels from a bottle includes a first layer having a vessel exit passage. A second layer is operatively connected to the first layer, and includes a vessel entry passage horizontally offset from the exit passage. A vessel dispensing layer is positioned between the first and second layers, is movable with respect to the first and second layers, and includes a holding chamber sized to receive the vessel. The holding chamber is movable from a first loading position in which the holding chamber is aligned with the entry passage and is horizontally offset from the exit passage to receive the vessel, to a second dispensing position in which the holding chamber is aligned with the exit passage and is horizontally offset from the entry passage to dispense the vessel through the exit passage. The holding chamber may be configured with a fulcrum and a ramp. Interchangeable alignment inserts and interchangeable chamber inserts may be inserted into slots within the second layer and vessel dispensing layer for receiving interchangeable inserts.
