      Mechanism Anticholinergic effects
Muscarinic acetylcholine receptor  Antagonist 		Anticholinergic effects
Muscarinic acetylcholine receptor  Antagonist
      Key Mechanism Factor 1
Factor Name Muscarinic acetylcholine receptor M Structure Sequence

Protein Function
The muscarinic acetylcholine receptor mediates various cellular responses, including inhibition of adenylate cyclase, breakdown of phosphoinositides and modulation of potassium channels through the action of G proteins. Primary transducing effect is Pi turnover.

      Mechanism Description
  • Additive anticholinergic effects by the combination of Benzatropine and Dicyclomine 

Recommended Action
      Management Caution is advised when agents with anticholinergic properties are combined, particularly in the elderly and those with underlying organic brain disease, who tend to be more sensitive to the central anticholinergic effects of these drugs and in whom toxicity symptoms may be easily overlooked. Patients should be advised to notify their physician promptly if they experience potential symptoms of anticholinergic intoxication such as abdominal pain, fever, heat intolerance, blurred vision, confusion, and/or hallucinations.
