Bilateral microinjections (0.2–2 nmol/site) of a potent M2muscarinic receptor agonist,cis-methyldioxolane (CD), but not those of a relatively selective M1receptor agonist (McN-A343; 3 nmol/site), into the intermediate portion of nucleus tractus solitarii (NTS) of pentobarbital-anesthetized rats elicited a decrease in blood pressure (23–52 mm Hg) and heart rate (16–50 bpm). Previous microinjections of a selective competitive M2receptor antagonist (AFDX-116; 0.8 nmol/site), but not those of a potent selective M1receptor antagonist (pirenzepine; 2 nmol/site), into the NTS blocked the effects of CD. These results indicate that the muscarinic receptors in the intermediate portion of NTS are of M2type.
