| Description | Diphenmanil methylsulfate (Diphemanil mesylate), a quaternary ammonium anticholinergic, binds muscarinic acetylcholine receptors and thus decreases secretory excretion of stomach acids, sweat, and saliva. |
| In vitro | Pharmacokinetic studies indicate that Diphemanil Methylsulphate is slowly absorbed, with a peak time (tmax) of 2-4 hours and an average half-life of 8.35 hours. Within 48 hours, 0.6%-7.4% of the administered dose is recovered in the urine. The compound exhibits poor gastrointestinal absorption, with bioavailability ranging from 15% to 25%. |
| In vivo | Diphemanil Methylsulfate exerts its anticholinergic effects primarily by binding to muscarinic M3 receptors, and it also acts directly on smooth muscle to provide antispasmodic benefits. |
| Synonyms | Diphemanil Methylsulfate, Diphemanil mesylate |
