The 32 pages that link to Atropine, each with the reason it gives.

• Autonomic nervous systemRelated: Blocking parasympathetic signaling can increase heart rate and reduce secretions.

• Muscarinic acetylcholine receptorRelated: Its broad receptor blockade reveals muscarinic contributions to heart rate, secretion, and pupil size.

• AlkaloidBroader topic: Its effects on the eyes, heart, and secretions demonstrate receptor-selective alkaloid action.

• Organophosphate poisoningRelated: It treats dangerous muscarinic effects but does not reverse muscle paralysis.

• BradycardiaRelated: It is used in some urgent cases of symptomatic bradycardia.

• Parasympathetic nervous systemCompared with: Its effects reveal what happens when muscarinic parasympathetic signaling is inhibited.

• EpinephrineCompared with: It treats some emergencies through a different receptor system than epinephrine.

• PralidoximeCompared with: Unlike pralidoxime, atropine blocks receptor effects rather than reactivating the enzyme.

• ScopolamineRelated: It shares scopolamine’s receptor target but differs in clinical effects and uses.

• Cholinergic crisisRelated: It treats dangerous muscarinic effects such as bronchorrhea and bradycardia, but not nicotinic weakness.

• Acetylcholinesterase inhibitorRelated: It counteracts muscarinic effects during severe cholinesterase-inhibitor poisoning.

• Nerve agentRelated: It treats some nerve-agent effects by reducing excessive muscarinic signaling.

• SarinRelated: It reduces life-threatening muscarinic effects of sarin poisoning, though it does not reactivate acetylcholinesterase.

• AnticholinergicBroader topic: It is used for bradycardia, organophosphate poisoning, and selected eye procedures.

• AntidoteBroader topic: It counters excess acetylcholine signaling in organophosphate poisoning.

• Anticholinergic syndromeBroader topic: It illustrates how therapeutic receptor blockade can cause the same pattern at excessive doses.

• Chemical warfare agentRelated: It is a key antidote for excessive cholinergic activity after nerve-agent exposure.

• Tokyo subway sarin attackRelated: Medical teams used antidotal treatment, including atropine, against sarin’s cholinergic effects.

• Atropa belladonnaBroader topic: It is the racemic form associated with belladonna’s principal antimuscarinic alkaloid.

• Tropane alkaloidBroader topic: It exemplifies how a tropane scaffold can interrupt parasympathetic signaling.

• Novichok agentsRelated: It counters some effects of excess acetylcholine during treatment.

• NeostigmineRelated: It is commonly paired with neostigmine to limit muscarinic effects during neuromuscular-blockade reversal.

• HyoscyamineCompared with: Atropine is the racemic form associated with hyoscyamine, while hyoscyamine is its naturally active levorotatory form.

• Neurogenic shockRelated: It may be used when clinically significant bradycardia accompanies neurogenic shock.

• PilocarpineCompared with: It blocks the receptor actions pilocarpine stimulates, including pupil constriction and glandular secretion.

• Poisoning of Alexei NavalnyRelated: It is part of standard treatment for symptoms caused by excessive acetylcholine signaling.

• SomanRelated: It counters dangerous muscarinic effects such as airway secretions and bronchoconstriction.

• Sick sinus syndromeRelated: It may be used for acute symptomatic bradycardia, though effects can be limited in intrinsic node disease.

• SolanineCompared with: Despite the shared nightshade association, atropine is chemically distinct and has a different primary action.

• Conium maculatumCompared with: Its receptor action and medical role differ from those of poison hemlock’s nicotinic-acting alkaloids.

• MuscarineRelated: It can reverse muscarinic effects in symptomatic muscarine poisoning.

• Tetraethyl pyrophosphateRelated: It counters muscarinic effects of acetylcholine accumulation, though not the enzyme inhibition itself.
