[2] [3] It is a fixed-dose combination of the medications diphenoxylate, as the hydrochloride, an antidiarrheal; and atropine, as the sulfate, an anticholinergic. [1] It is taken by mouth. [2] Onset is typically within an hour. [4] Side effects may include abdominal pain, angioedema, glaucoma, heart problems, feeling tired, dry mouth, and ...
Topical atropine is used as a cycloplegic, to temporarily paralyze the accommodation reflex, and as a mydriatic, to dilate the pupils. [15] Atropine degrades slowly, typically wearing off in 7 to 14 days, so it is generally used as a therapeutic mydriatic, whereas tropicamide (a shorter-acting cholinergic antagonist) or phenylephrine (an α-adrenergic agonist) is preferred as an aid to ...
Organophosphate based nerve agent poisoning, such as VX, sarin, tabun, and soman (atropine is favoured in conjunction with an oxime, usually pralidoxime) [6] [7] Anticholinergics generally have antisialagogue effects (decreasing saliva production), and most produce some level of sedation, both being advantageous in surgical procedures. [8] [9]
Diphenoxylate is used to treat diarrhea in adults; it is only available as a combination drug with a subtherapeutic dose of atropine to prevent abuse. [2] It should not be used in children due to the risk of respiratory depression. [2] It does not appear harmful to a fetus but the risks have not been fully explored. [2]

In the United States, belladonna is marketed as a dietary supplement, typically as an atropine ingredient in over-the-counter cold medicine products. [40] [56] Although such cold medicine products are probably safe for oral use at typical atropine dosages (0.2 milligram), there is inadequate scientific evidence to assure their effectiveness. [56]
Muscarinic antagonist effects and muscarinic agonist effects counterbalance each other for homeostasis. Certain muscarinic antagonists can be classified into either long-acting muscarinic receptor antagonists ( LAMA s) or short-acting muscarinic receptor antagonists ( SAMA s), depending on when maximum effect occurs and for how long the effect ...
Ipratropium is a derivative of atropine [3] but is a quaternary amine and therefore does not cross the blood–brain barrier, which prevents central side effects. Ipratropium should never be used in place of salbutamol (albuterol) as a rescue medication.
