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.
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.
Atropine sulfate drops sublingually, scopolamine transdermal patches, robinul subcutaneous injections, or HYOSCYAMINE sublingual tablets can be used to dry the secretions that cause the "death rattle."
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
hell no
well find out...
atropine
it increase amount of apposition between iris and lens
I think Belladonna is derived from it. ------------------------------- REVISION OF ANSWER ----------------------------- belladonna is another name for the plant 'deadly nightshade'. Atropine is the name of the tropane alkaloid extracted from deadly nightshade and various other plants of the family Solanaceae. A potentially deadly drug, it acts as a competitive antagonist for the muscarinic acetylcholine receptor. It is classified as an anticholinergic drug.

No!
Atropine is a drug prepared from propanal and ethanol
No! Atropine is commonly used with steroids after proper diagnosis.
