Question: 1 / 400

What are anticholinergics primarily used for?

Immediate relief of asthma symptoms

Prevention of bronchospasm in chronic bronchitis or emphysema

Anticholinergics are primarily used to prevent bronchospasms in patients with chronic bronchitis or emphysema. These medications work by blocking the action of acetylcholine, a neurotransmitter that constricts the airways. This action helps to relax the muscles in the airways and prevent bronchospasms. A is incorrect because anticholinergics do not provide immediate relief for asthma symptoms. C is incorrect because anticholinergics are not typically used to treat hypertension. D is incorrect because anticholinergics are not used to treat allergic reactions.
