Question

which of the following is a short acting anticholinergic agent used to treat bronchospasm?
tiotropium
epinephrine
almeterol
ipratropium bromide

Explanation:

To determine the short - acting anticholinergic agent for bronchospasm:

1. Analyze Tiotropium: It is a long - acting anticholinergic, so it is not the answer.
2. Analyze Epinephrine: It is an adrenergic agonist (sympathomimetic), not an anticholinergic, so it is not the answer.
3. Analyze Almeterol: It is a long - acting beta - agonist, not an anticholinergic, so it is not the answer.
4. Analyze Ipratropium bromide: It is a short - acting anticholinergic agent used to treat bronchospasm.

Answer:

D. Ipratropium bromide
