Antimuscarinic drugs

Antimuscarinic drugs are medications that block certain nerve signals called acetylcholine from attaching to specific receptors called muscarinic receptors. These receptors are found in various parts of the body, including the bladder, lungs, and salivary glands. By blocking these signals, antimuscarinic drugs help reduce muscle spasms, decrease secretions, and improve symptoms like overactive bladder, chronic bronchitis, or excessive salivation. They are used in conditions where controlling muscle activity or secretions is beneficial. However, they can also cause side effects like dry mouth, blurred vision, or constipation because they affect normal bodily functions controlled by the nervous system.
