Atropine:
Its a naturally occurring tropane alkaloid ( Tropane alkaloids are a class of alkaloids and secondary metabolites that contain a tropane ring in their chemical structure) extracted from Deadly Nightshade ( Scientific Name: Atropa belladonna), Jimson weed ( SN: Datura stramonium) and other plants of Solanaceae family.
Scopolamine ( Hyoscine):
Scopolamine, also known as levo-duboisine and hyoscine, is a tropane alkaloid drug with muscarinic antagonist effects. It is among the secondary metabolites of plants from Solanaceae (nightshade) family of plants, such as henbane, jimson weed, Angel's Trumpets (Daturaor Brugmansia), and corkwood (Duboisia).
Difference b/w Atropine and Hyoscine:
ATROPINE HYOSCINE
1. Selective muscarinic blocker. 1. Selective muscarinic blocker.
2. Obtained from Atropa belladonna and 2. Obtained from Hyoscyamus Niger.
Datura stramonium.
3. Racemic mixture of alkaloids. 3. Levo-isomer of alkaloids.
4. CNS Stimulant 4. CNS Depressant
5. More actions on heart, bronchial smooth 5. More action on eyes, exocrine
muscles and GIT. glands- Salivary glands, sweat,and
tracheo-bronchial.
6. Long duration of action. 6. Short duration of action.
From my understanding there is not much of a difference. Atropine and hyoscyamine are isomers of each other but other than their shape position, they are the same. Scopolamine has a chemical structure that is very similar but a little bit different, thus it is mostly recognized in the body as the same chemical as the former two.
Physostigmine is the antidote for atropine poisoning. It works by reversing the effects of atropine on the body's nervous system. It should be administered under medical supervision due to potential side effects.
The functional group of atropine is a tertiary amine, as it contains a nitrogen atom bonded to three carbon atoms.
Atropine counteracts nerve gas by blocking the action of acetylcholine at nerve receptors. Nerve gases inhibit the enzyme acetylcholinesterase, which leads to an accumulation of acetylcholine and overstimulation of nerve cells. Atropine acts as an antidote by binding to the same receptors as acetylcholine, preventing excessive stimulation.
Atropine nasal sprays improve rhinorrhea and postnasal drip. Ipratropium bromide nasal spray dilates and relaxes bronchial passageways. These two nasal sprays are not the same, they are used for two completely different medical issues.
There is not much difference between them. Atropine and Hysocyamine are isomers of each other. Atropine is (+/-) Hyoscyamine, the tropic acid ester of tropine. The naturally occurring alkaloid is (-) Hyocyamine. Thus it can be said that Hyoscyamine is a racemic form of Atropine. In other words, Atropine is a racemic variety of tropine tropate, hysocyamine being the levorotatory enantiomorph of tropine tropate.
It doesn't atropine only acts on muscarinic receptors (it's a competitive antagonist here for ACh), but histamine acts on different receptors (histamine receptors). There is no direct interaction between atropine and histamine receptors

Atropine is a drug prepared from propanal and ethanol
No! Atropine is commonly used with steroids after proper diagnosis.
Atropine - album - was created on 2009-08-10.
purpose of Demerol and atropine sulfate as preanaesthetic
Atropine is generally considered to be a cholinergic muscarinic receptor antagonist.
Atropine does not only block nicotinic receptors but also acetylcholine at muscarinic receptors
