Muscarinic effect

The muscarinic effect refers to the physiological responses mediated by muscarinic acetylcholine receptors, which are G-protein-coupled receptors found in various tissues, including the heart, smooth muscle, and glands. These effects are crucial in clinical practice as they influence autonomic functions such as heart rate, glandular secretion, and smooth muscle contraction. A key association is the role of muscarinic agonists in managing conditions like glaucoma, where they promote aqueous humour outflow.
