      Drug Name Benzatropine Potassium chloride
      Mechanism Delayed gastric emptying Absorption affected by delayed gastric emptying
      Key Mechanism Factor 1
Factor Name Gastrointestinal Motility
Factor Description Gastrointestinal motility is an important factor in determining the absorption of orally administered drugs, and it controls the residence time of the drug in the digestive tract.
      Mechanism Description
  • Altered absorption of Potassium chloride due to GI dynamics variation caused by Benzatropine 

Recommended Action
      Management The use of oral solid formulations of potassium chloride is considered contraindicated in patients receiving agents with anticholinergic properties at sufficient doses to exert anticholinergic effects. A liquid formulation of potassium chloride should be considered. Patients prescribed a solid oral formulation should be advised to discontinue potassium therapy and contact their physician if they experience potential symptoms of upper GI injury such as severe vomiting, abdominal pain, distention, and gastrointestinal bleeding.
