Step-by-step explanation:
Atropine and scopolamine are muscarinic antagonists derived from the Atropa genus of plants. Although both drugs have similar effects on the body, there are some differences between them. Atropine acts primarily on the heart and is commonly used to treat bradycardia and as an antidote for certain poisonings. On the other hand, scopolamine acts mainly on the central nervous system and is commonly used to treat motion sickness and as a sedative. While atropine can be fatal in high doses, scopolamine is safer to use in controlled low doses, such as in the transdermal patch for motion sickness.
