 Mechanism of Benzatropine-Bisoprolol Interaction (Severity Level: Moderate)
     Altered gastrointestinal dynamics Click to Show/Hide Mechanism Graph
Could Not Find 2D Structure
      Drug Name Benzatropine Bisoprolol
      Mechanism 1 Decrease gastrointestinal motility Absorption is influenced by gastrointestinal motility
      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 Bisoprolol due to GI dynamics variation caused by Benzatropine 
     Additive CNS depression effects Click to Show/Hide Mechanism Graph
Could Not Find 2D Structure
      Drug Name Benzatropine Bisoprolol
      Mechanism 2 CNS depression effects CNS depression effects
      Key Mechanism Factor 2
Factor Name CNS depression effects
Factor Description CNS depressants are drugs that inhibit or suppress brain activity and can reduce mental and physical processes. Excessive CNS depression can lead to decreased heart rate, slow breathing (less than 10 breaths per minute), extreme confusion or loss of memory, nausea and vomiting, poor judgment, blue lips or fingertips, irritability and aggression, and clammy or cold skin.
      Mechanism Description
  • Additive CNS depression effects by the combination of Benzatropine and Bisoprolol 
     Antagonize the effects of beta receptor blockers Click to Show/Hide Mechanism Graph
      Drug Name Benzatropine Bisoprolol
      Mechanism 3 Tachycardia
Muscarinic acetylcholine receptor  Antagonist 		Bradycardia
Beta adrenergic receptor  Antagonist
      Key Mechanism Factor 3
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.

      Key Mechanism Factor 4
Factor Name Adrenergic receptor beta Structure Sequence
Protein Family G-protein coupled receptor 1 family
Protein Function
Beta-adrenergic receptors mediate the catecholamine-induced activation of adenylate cyclase through the action of G proteins. This receptor binds epinephrine and norepinephrine with approximately equal affinity. Mediates Ras activation through G(s)-alpha- and cAMP-mediated signaling. Involved in the regulation of sleep/wake behaviors (PubMed:31473062).

      Mechanism Description
  • Antagonize the effect of Bisoprolol when combined with Benzatropine 

Recommended Action
      Management Patients should be monitored for potentially excessive CNS adverse effects (e.g., drowsiness, dizziness, lightheadedness, confusion, blurred vision) if anticholinergic agents are used in combination with beta blockers. Patients should be counseled to avoid activities requiring mental alertness until they know how these agents affect them.
