noun. (Pharmaceutical: Drugs) Atropine is a poisonous alkaloid, obtained from deadly nightshade, which has an inhibitory action on the autonomic nervous system. Atropine is used in pre-anesthetic medication, to speed a slow heart rate, and in first aid to counter exposure to chemical nerve agents.
Where is atropine derived from?
Source and Synthesis Atropine and the genus name for deadly nightshade derive from Atropos, one of the three Fates who, according to Greek mythology, chose how a person was to die.

How much atropine is fatal?
In extreme toxicity, circulatory collapse secondary to respiratory failure may occur after paralysis and coma. Ten milligrams or less may be fatal to a child, while there is no known adult lethal dose. All Datura plant species have endogenous atropine and other assorted anticholinergic alkaloids.
What are the indications for atropine?
Atropine Sulfate Injection, USP, is indicated for temporary blockade of severe or life threatening muscarinic effects, e.g., as an antisialagogue, an antivagal agent, an antidote for organophosphorus or muscarinic mushroom poisoning, and to treat bradyasystolic cardiac arrest.
What is the meaning of the drug atropine?

Etymology: Gk, Atropos, one of the three Fates. an alkaloid from Atropa belladonna and Datura stramonium plants. It is related to other drugs, such as scopolamine and hyoscyamine, and has a similar action of blocking parasympathetic stimuli by raising the threshold of response of effector cells to acetylcholine.
When to use atropine as an anticholinesterase agent?
In clinical practice, atropine, a nonselective muscarinic receptor blocker, is employed to prevent the parasympathomimetic effects induced by neostigmine when the anticholinesterase agent is clinically used to reverse the blockage of neuromuscular transmission caused by non-depolarizing muscular relaxants (Barrio, Miguel, Garcia, & Pelegrin, 2007).
How does atropine prevent parasympathetic action in the body?
By preventing parasympathetic action where there is dual autonomic innervation, atropine allows the sympathetic influence to predominate, e.g. it increases the heart rate, dilates the pupils, reduces salivary secretion and relaxes intestinal smooth muscle.
