What complication can atropine cause related to urinary function?

Atropine is an anticholinergic medication that works by blocking the effects of acetylcholine, a neurotransmitter involved in various bodily functions, including the regulation of the urinary system. By inhibiting the action of acetylcholine on the muscarinic receptors in the bladder, atropine decreases bladder muscle contractions which can lead to urinary retention.

Urinary retention occurs because the medication reduces the urge to void by relaxing the detrusor muscle, which is responsible for bladder contraction. This can make it difficult for individuals to fully empty their bladder, resulting in discomfort and an increased risk for complications such as urinary tract infections.

While options like urinary incontinence or frequent urination may pertain to issues with bladder control, they are not typically associated with the pharmacological effects of atropine. Instead, atropine is more likely to cause retention due to its relaxing effect on the bladder. Therefore, its impact on urinary function primarily manifests as urinary retention.
