Beschreibung

General description

Atropine, a belladonna alkaloid, is an anti-muscarinic drug. It is extracted from Atropa belladonna. Atropine is an anticholinergic agent, which is linked to passive mydriasis. It blocks acetylcholine receptors in brain and has hallucinogenic effects. Atropine eye drops are used to treat uveitis and early amblyopia. It is also used to treat nerve agents.

Application

Atropine has been used to study it′s in vitro cytotoxicity, antiviral and antimicrobial activities. It has also used to antagonize acetylcholine induced K⁺ current.

Atropine has been used:

• as a tastant to analyse the bitter taste perception in Drosophila larvae
• as a muscarinic acetylcholine autoreceptors (mAChRs) antagonist to investigate the involvement of individual mAChR subtypes in the control of synapse elimination
• to investigate the pathways of serotonin (5-HT) action in zebrafish hearts[1]

Biochem/physiol Actions

Kompetitiver nichtselektiver Antagonist an zentralen und peripheren muskarinischen Acetylcholin-Rezeptoren.

Atropine is used to treat myopia and ocular axial elongation in Asian children. Small dosage of atropine is used to slow down the heart rate.
