Anticholinergic drugs mainly refers to the clinical use of antispasmodic and analgesic drugs, common atropine, scopolamine, belladonna, etc., and their adverse reactions are different, as follows.
1. Atropine: it may cause acute closed-angle glaucoma, atropine has the effect of paralyzing the pupillary sphincter, pointing at the eye or injection will lead to pupil dilatation, interruption of atrial fluid circulation, thus inducing acute glaucomatous episodes; it may also cause facial flushing, dry mouth, and other side effects, which is due to the atropine caused by the dilation of the facial capillaries, the glands to reduce secretion caused by.
2. Scopolamine: The side effects of scopolamine are similar to those of atropine, which will lead to facial capillary dilatation and decreased secretion of glands, resulting in side effects such as facial flushing and dry mouth.
3. Belladonna: Belladonna has the effect of inhibiting glandular secretion, so it may lead to side effects such as dry mouth, reduced sweating, and dryness of the oral mucosa or nasal mucosa.
