      Drug Name Darifenacin Pyridostigmine
      Mechanism Anticholinergic effects
Muscarinic acetylcholine receptor  Antagonist 		Cholinergic effects
Acetylcholinesterase  Inhibitor
      Key Mechanism Factor 1
Factor Name Muscarinic acetylcholine receptor M Structure Sequence
Protein Family G-protein coupled receptor 1 family
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
  • Antagonize the effect of Pyridostigmine when combined with Darifenacin 

Recommended Action
      Management Agents with potent anticholinergic activity should preferably be avoided in patients receiving cholinergic skeletal muscle stimulants. If concurrent use is necessary, patients treated for myasthenia gravis should be monitored for potential exacerbation of symptoms.
