1 point
which of the following medications is classified as an anticholinergic?
tiotropium
albuterol
salmeterol
formoterol

Explanation:

1. Antibiotics target bacterial cells, not viruses, so they are ineffective against viral colds. The other options help manage cold symptoms or support recovery.
2. Tiotropium is an anticholinergic medication that blocks acetylcholine receptors, used for respiratory conditions. Albuterol, Salmeterol, and Formoterol are beta-2 adrenergic agonists, not anticholinergics.

Answer:

1. Antibiotics
2. Tiotropium
