Atropine is an anticholinergic drug that can effectively relieve smooth muscle spasm and reduce glandular secretion. Atropine can be used in the following cases: first, to treat abdominal pain and stomach pain in children, because most of the causes of abdominal pain and stomach pain in children are related to smooth muscle spasm of the gastrointestinal tract, so the application of atropine can play a good role in relieving smooth muscle spasm and thus play a pain-relieving effect. Secondly, it is applied to organophosphorus poisoning. After the occurrence of organophosphorus poisoning in children, atropine can also be applied for treatment, so children can also apply atropine, but under the guidance of professional doctors.
