Valved inhalation chambers are important instruments to increase the available dose of pressurized metered dose inhalers, in this study inhalation chambers are compared by means of the System of Objectified Judgement Analysis (SOJA) method. The SOJA method is a model for rational drug selection. The relevant selection criteria for inhalation chambers are defined and judged by a panel of experts and each selection criterion is given a relative weight. The following inhalation chambers were included: Aerochamber, Inspirachamber, Optichamber, Volumatic and Vortex. Selection criteria were: Transparancy, Feedback system in case of too forceful inhalation, Antistatic properties, Dose delivery, Availability of mouth masks, Easy to carry, Suitability for children and inclusion in Summaries of Product Characteristics of metered dose inhalers. Aerochamber showed by far the highest score. If performed well on all selection criteria. Vortex and Optichamber also performed well. Volumatic showed the lowest score.
