This is a dry powder inhaler that was made available in 1948 in USA by Abbott. Small re-usable ‘sifter’ cartridges were prepared and loaded into the inhaler for the medicine to be taken. Penicillin cartridges were available - the text shows the PDR entry. Additionally, cartridges of the bronchodilator norisodrine sulfate were also available. Advert download 1 (PDF)
