654-2 has obvious peripheral anticholinergic effects, which can resist the intestinal and bladder smooth muscle contraction and blood pressure drop caused by acetylcholine, and can reduce intestinal tone in the body, but has no central sedative effect.

Uses of 654-1 and 654-2:

Scopolamine is one of the most potent alkaloids in belladonna, which can be used to block parasympathetic nerves and can also be used as a central nervous system depressant.

Scopolamine has obvious peripheral anticholinergic effect, which can resist the intestinal and bladder smooth muscle contraction and blood pressure drop caused by acetylcholine, and can reduce intestinal tone in the body, and the intensity of action is similar to that of atropine.

Clinically, acute appendicitis, anaphylactic shock, acute nephritis combined with heart failure, hypertensive encephalopathy, lung diseases and dichlorvos poisoning have achieved good curative effects.

Commonly used its hydrobromide, white crystalline or crystalline powder, odorless, very soluble in water, soluble in ethanol, hyoscyamine dilates the pupil and inhibits the secretion of glands The effect is weak, and it rarely causes central excitatory symptoms.

Physicochemical properties:Scopolamine is density:, boiling point:

At 760 mmHg, refractive index: , melting point: 176 181, commonly used its hydrobromide, white crystalline or crystalline powder, odorless.
