Which type of nasal discharge is commonly associated with anticholinergic medication use?

Anticholinergic medications are known to dry secretions in the respiratory tract, including nasal passages. As a result, the type of nasal discharge that is commonly associated with the use of these medications is clear and watery. This occurs because anticholinergics inhibit the action of acetylcholine, which is involved in stimulating mucosal secretion. Consequently, instead of producing thick or purulent secretions, the nasal passages may become dry, leading to a clear, watery discharge as the body attempts to maintain moisture despite the suppressed mucous secretion. This characteristic aligns with the body's response to anticholinergic effects, making clear, watery discharge the correct association with such medication use.
