Gene Name ADRB1
Uniprot ID ADRB1_HUMAN
KEGG Pathway hsa:153
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).

      Key Mechanism Factor 2
Factor Name Guanylate cyclase soluble Structure Sequence
Protein Family Adenylyl cyclase class-4/guanylyl cyclase family
Protein Function
There are two types of guanylate cyclases: soluble forms and membrane-associated receptor forms. Activated by nitric oxide in the presence of magnesium or manganese ions.

      Mechanism Description
  • Additive hypotensive effects by the combination of Nebivolol and Nitrous acid 

Recommended Action
      Management Sodium nitrite should be used with caution in the presence of concomitant antihypertensive agents, diuretics, vasodilators, or PDE5 inhibitors. Hemodynamics should be monitored during and after administration of sodium nitrite, and the infusion rate decreased if significant hypotension occurs. In addition, methemoglobin levels should be monitored and oxygen administered during treatment whenever possible.
