At least a portion of the pushrod is movably disposed in the delivery passage. A distal end portion of the pushrod is configured to move a drug dosage form through at least a portion of the delivery passage to convey the drug dosage form through the exit port when the distal end portion of the pushrod is moved from a first position to a second position. A surface of at least one of the pushrod or the housing defining the delivery passage is nonplanar, curved and/or contoured.
