A Study of Inhaled Atropine Sulfate in Healthy Adults
Development of an Inhaled, Dry Powder Delivery System for the Administration of Atropine Sulfate
MicroDose Defense Products, LLC is developing an atropine dry powder inhaler (ADPI). This pilot study compares the pharmacokinetics (PK) of inhaled dry powder atropine as delivered by the ADPI to atropine delivery from the AtroPen autoinjector.
