A Study of Inhaled Atropine Sulfate in Healthy Adults

August 10, 2010 updated by: MicroDose Defense Products L.L.C.

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.
