Atropine is an alkaloid originally synthesized from Atropa belladonna. It is a racemic mixture of d-and l-hyoscyamine, of which only l-hyoscyamine is pharmacologically active.[A251670,L42835] Atropine is generally available as a sulfate salt and can be administered by intravenous, subcutaneous, intramuscular, intraosseous, endotracheal and ophthalmic methods. Oral atropine is only available in combination products.[A251660,L42840] Atropine is a competitive, reversible antagonist of muscarinic receptors that blocks the effects of acetylcholine and other choline esters.[A251660,L42815,L42825,L42835] It has a variety of therapeutic applications, including pupil dilation and the treatment of anticholinergic poisoning and symptomatic bradycardia in the absence of reversible causes.[A251660] Atropine is a relatively inexpensive drug and is included in the World Health Organization List of Essential Medicines.[A251675]

The intravenous, intramuscular, subcutaneous, intraosseous and endotracheal use of atropine is indicated for the temporary blockade of severe or life-threatening muscarinic effects.[L42815,L42835] The intramuscular use of atropine in the form of a pen injector is indicated for the treatment of poisoning by susceptible organophosphorus nerve agents having cholinesterase activity as well as organophosphorus or carbamate insecticides in adult and pediatric patients.[L42825] The ophthalmic use of atropine is indicated for mydriasis, cycloplegia, and penalization of the healthy eye in the treatment of amblyopia.[L42830] In combination with difenoxin or diphenoxylate (tablets for oral use), atropine is indicated as adjunctive therapy in the management of acute nonspecific diarrhea.[L42840,L42865]
