Diphemanil Methylsulfate is a quaternary ammonium anticholinergic, it binds muscarinic acetycholine receptors (mAchR). In vitro
Diphemanil Methylsulfate exerts its action by primarily binding the muscarinic M3 receptor. In addition to its well known antimuscarinic effects, Diphemanil Methylsulfate also possesses direct smooth musclespasmolytic activity.
In vivo
The pharmacokinetic experiments show that absorption of diphemanil methylsulphate is slow (tmax = 2 to 4 h), the mean half-life is 8.35 h, and the amount of the drug recovered in urine within 48 h ranges from 0.6 to 7.4% of the administered dose. Poorly absorbed from the gastrointestinal tract with an absolute bioavailability of 15 to 25%. Cell Data
