Atropine Eye Drops: A Proposed Field Expedient Substitute in the Absence of Atropine Autoinjectors.

Nerve agents are a threat to military and civilian health. The antidote, atropine sulfate, is delivered by autoinjector, which is a limited resource. We propose the use of 1% atropine ophthalmic solution (supplied commercially in 5mL or 15 mL bottles) via oral, ocular, and intranasal administration as an expedient substitute in austere environments.
