Atropa belladonna
Plante européenne notoirement toxique utilisée depuis l'antiquité dans la médecine populaire et la pharmacie ; source d'atropine et de scopolamine.
Atropa belladonna (deadly nightshade) is a highly toxic European plant historically used for its tropane alkaloids, primarily atropine, scopolamine, and hyoscyamine. Despite its dangerous profile, these compounds have well-established pharmaceutical applications in ophthalmology, cardiology, and as antispasmodics. Modern use is strictly limited to purified alkaloids due to the plant's narrow therapeutic index and severe toxicity.
The tropane alkaloids competitively antagonize muscarinic acetylcholine receptors (M1–M5), blocking parasympathetic neurotransmission. Atropine preferentially blocks M2 receptors in the heart and M3 receptors in smooth muscle, leading to tachycardia, bronchodilation, and reduced glandular secretions. Scopolamine exhibits greater central nervous system penetration, causing sedation, amnesia, and antiemetic effects. These compounds also possess weak antihistaminic and local anesthetic properties.
