Related to muscarinic receptors: cholinergic receptors

mus·ca·rin·ic re·cep·tors

membrane-bound proteins with an extracellular domain that contains a recognition site for acetylcholine (ACh); combination of Ach with the receptor initiates a physiologic change (slowing of heart rate, increased glandular secretory activity, and stimulation of smooth muscle contractions); changes are observed after treatment with the mushroom alkaloid muscarine. Muscarinic receptors are to be distinguished from nicotinic receptors.

Baseline and frequent monitoring should be completed of the patient's vital signs, urinary output, bowel sounds, and cardiac rhythm to determine therapeutic effect and signs of excessive anticholinergic stimulation brought about by muscarinic receptor blockade.
Second, the blockade of other muscarinic receptor subtypes leads to adverse effects of antimuscarinic therapy.
Activating the worms' muscarinic receptors triggered the identical behavior and biochemical response that starvation did, showing that the receptor controls the muscles' response to hunger.
Scopolamine is believed to bind well to all types of muscarinic receptors. In their study of 16 agents, Wood and Graybiel found that oral scopolamine was the most effective single agent in preventing vertigo.
Compared with older anticholinergics approved for OAB, solifenacin is a more selective muscarinic receptor blocker, as is trospium chloride, Richard Bercik, M.D., director of the division of urogynecology and reconstructive surgery at Yale University, New Haven, said in an interview.
As with other anticholinergics, tiotropium causes bronchodilation by blocking the muscarinic receptors in the parasympathetic nervous system.
Upon release into the synaptic cleft, acetylcholine diffuses to its site of action to combine with nicotinic or muscarinic receptors on the post-synaptic cell or pre-junctional receptors on the nerve terminal itself to auto-regulate further release.
KarXT, a proprietary oral modulator of muscarinic receptors, is the Company's lead product candidate that combines xanomeline, a novel muscarinic agonist, with trospium, an approved muscarinic antagonist, to preferentially stimulate muscarinic receptors in the central nervous system (CNS).
