What is the primary action of anticholinergic medications in treating overactive bladder?

Anticholinergic medications primarily target the muscarinic receptors in the bladder, leading to a reduction in bladder contractions. This action is particularly beneficial in treating overactive bladder, a condition characterized by involuntary bladder contractions that result in sudden and frequent urges to urinate. By decreasing these involuntary contractions, anticholinergics help to improve bladder control and reduce episodes of urgency and incontinence.

The mechanism involves inhibiting the action of acetylcholine, a neurotransmitter responsible for signaling bladder muscle contractions. This results in a more controlled and less reactive bladder, allowing individuals to manage their symptoms more effectively. The focus on decreasing bladder contractions addresses the core problem in overactive bladder, making this treatment option a standard approach in managing the condition.
