What class of drug is atropine, and what are some of its side effects?

Atropine is classified as an anticholinergic drug, which means it works by blocking the action of acetylcholine, a neurotransmitter involved in numerous bodily functions, including the autonomic nervous system. This classification is important because anticholinergic drugs are commonly used to treat various conditions, including bradycardia (slow heart rate), and to prevent salivation and airway secretions during surgery.

The side effects associated with atropine include dry mouth and blurred vision, both of which are typical for anticholinergic medications. Dry mouth occurs due to reduced saliva production, while blurred vision results from the drug's effect on the eye muscles, which can lead to pupil dilation (mydriasis) and impaired accommodation (the ability of the eye to focus on near objects). Other common side effects can include urinary retention, constipation, and increased heart rate, but the specific side effects stated, dry mouth and blurred vision, align directly with the pharmacological action of atropine as an anticholinergic agent. Understanding these effects helps both healthcare professionals and patients recognize and manage potential reactions to the medication effectively.
