Atropine blocks muscarinic acetylcholine receptors. Acetylcholine (ACh) is the neurotransmitter of the parasympathetic nervous system and blocking its action means the pupil cannot constrict.
Cocaine inhibits the reuptake of noradrenaline within a nerve synapse. When a solution of cocaine is dropped into the eye, noradrenaline is no longer reabsorbed by neurons, and its levels increase. Noradrenaline, the neurotransmitter for the SNS, causes dilation of the pupil. Many other drugs such as amphetamines and psychedelic drugs (LSD, psychedelic mushrooms, mescaline, MDMA, Datura stramonium) are also known to cause mydriasis. The mydriasis caused by cocaine is used as a diagnostic test for Horner's Syndrome, in which the pupil is not dilated by cocaine.
Antihistamines and tricyclic antidepressants may cause mydriasis.
