M2 and M3 antagonism does not affect amplitude or AUC of basal spontaneous contractions. A: effect of 0.1 μM AF-DX 116 on basal spontaneous contractions. Values are means (SD); n = 4. B: effect of 0.05 μM 4-diphenylacetoxy-N-(2-chloroethyl)piperidine hydrochloride (4-DAMP mustard) on basal spontaneous contractions. Values are means (SD); n = 12. *P < 0.05 vs. basal. M, muscarinic.
