A metered-dose inhaler having a medication-containing cartridge and a tubular outlet is used with an aerosol holding chamber having an elongated body having a rear end wall formed with a hole shaped to fit snugly around the tubular outlet of the inhaler, a longitudinally extending side wall, and a front end wall. A mouthpiece formed on the front end wall has a large-diameter tubular rear portion extending forward from the front end wall, a small-diameter tubular front bite portion extending forward from the large-diameter rear portion, and a transverse wall between the rear and front portions and extending generally perpendicular thereto. The front bite portion is of a height equal to at most half a height of the large-diameter rear portion. |
