Final answer:
Diphenhydramine works through anticholinergic mechanisms to reduce allergy symptoms.
Step-by-step explanation:
Anticholinergic mechanisms refer to the pharmacological actions or effects that block or inhibit the activity of acetylcholine, a neurotransmitter in the central and peripheral nervous systems. Acetylcholine plays a crucial role in the transmission of nerve impulses and is involved in the regulation of various physiological processes, including muscle contraction, heart rate, glandular secretion, and neurotransmission.
Diphenhydramine works through anticholinergic mechanisms. It blocks the action of acetylcholine, a neurotransmitter that plays a role in various bodily functions. By blocking the action of acetylcholine, diphenhydramine helps to reduce symptoms of allergies, such as itching, sneezing, and runny nose.
