KEGG Pathway hsa:154
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. The beta-2-adrenergic receptor binds epinephrine with an approximately 30-fold greater affinity than it does norepinephrine.

      Mechanism Description
  • Antagonize the effect of Acebutolol when combined with Ritodrine 

Recommended Action
      Management In general, the use of beta blockers with ritodrine is discouraged. Selective beta blockers (e.g. acebutolol, atenolol, betaxolol, bisoprolol, metoprolol) may be preferable if the use of a beta blocker is unavoidable.
