Atropine, a natural tropane alkaloid found in plants like deadly nightshade (*Atropa belladonna*), is officially categorized as a potent anticholinergic and antimuscarinic agent. This classification explains its mechanism of action and its diverse uses in medical practice, particularly in emergency and critical care settings.

Included on the World Health Organization's List of Essential Medicines, atropine is a cornerstone of modern medical practice [1.7.1, 1.7.2]. But what type of drug is atropine considered, and why is it so vital in both emergency and routine procedures?

Atropine is a naturally occurring alkaloid, originally derived from plants like deadly nightshade, with a long history of medicinal use. Its drug classification is primarily as an anticholinergic and, more specifically, an antimuscarinic agent, known for blocking the effects of the neurotransmitter acetylcholine. This versatile medication is a cornerstone in emergency medicine, ophthalmology, and various other clinical applications.

Over six decades since its approval, tropicamide remains a standard eye medication used to dilate pupils for eye examinations. The question, 'Is tropicamide a muscarinic antagonist?', goes to the core of its pharmacological action, revealing how this anticholinergic agent achieves its effect on the eye's delicate muscles.

Originally isolated from plants in the nightshade family, such as deadly nightshade, atropine is a potent anticholinergic agent with diverse medical applications. So, what does atropine do? It exerts its effects by blocking the action of acetylcholine, a key neurotransmitter, thereby impacting various bodily systems, from cardiac function to glandular secretions and the eyes.

Included on the World Health Organization's List of Essential Medicines, atropine is a naturally derived alkaloid from plants like the deadly nightshade (Atropa belladonna) [1.3.3, 1.7.5]. Understanding **what is the mechanism of action of atropine** is key to its many emergency and clinical uses.

Atropine is a naturally occurring alkaloid derived from the deadly nightshade plant, *Atropa belladonna*, with a history of medicinal use dating back centuries. Today, this powerful anticholinergic medication is used in modern medicine to block the action of the neurotransmitter acetylcholine, addressing a wide range of critical medical issues.
