Which of the following is NOT a side effect of anticholinergic drugs?

• A. Dry mouth
• B. Palpitations
• C. Excessive salivation
• D. Dizziness

Answer: (C)

Anticholinergic drugs are known for their mechanism of action, which involves blocking the action of acetylcholine in the nervous system. This leads to a variety of side effects due to reduced activity of the parasympathetic nervous system. Common side effects include dry mouth, palpitations, and dizziness, all of which are consistent with the effects of blocking acetylcholine. The statement about excessive salivation is significant because anticholinergic drugs typically cause a decrease in salivation rather than an increase. This reduction in secretions is a hallmark effect of anticholinergic therapy and is commonly experienced by patients taking these medications. Therefore, excessive salivation is not associated with anticholinergic drugs and serves as the correct choice for what is NOT a side effect of these medications.
