Almost identical numbers of people reported at least one adverse event (60%) in each group (n=585, 14 RCTs, RR 0.99 CI 0.87 to 1.13), although trifluoperazine was more likely to cause extrapyramidal adverse effects overall when compared to low potency antipsychotics such as chlorpromazine (n=130, 3 RCTs, RR 1.66 CI 1.03 to 2.67, NNH 6 CI 3 to 121).

Diphemanil methylsulfate is a quaternary ammonium anticholinergic. It binds muscarinic acetycholine receptors and thereby decreases secretory excretion of stomach acids as well as saliva and sweat.IC50 value: Target: mAChRDiphemanil Methylsulfate exerts its action by primarily binding the muscarinic M3 receptor.
