title: Automatic piercing spinhaler (Halermatic): a comparative study.
abstract: Fifty patients, 27 females and 23 males with a mean age of 30 years and a history of chronic asthma, were studied during treatment with cromolyn sodium administered via the standard spinhaler and a new automatic piercing spinhaler, Halermatic. The study period consisted of a baseline period of 3 weeks (spinhaler use) and an 8-week period of Halermatic use. In the final analysis of results, it was noted that fewer inhalations (P less than .001) were needed to empty the cromolyn Spincaps with the Halermatic and a higher number of patients (61%) preferred the Halermatic over the Spinhaler.
