Gene Name SLC12A1
Uniprot ID S12A1_HUMAN
KEGG Pathway hsa:6557
Protein Family SLC12A transporter family
Protein Function
Renal sodium, potassium and chloride ion cotransporter that mediates the transepithelial NaCl reabsorption in the thick ascending limb and plays an essential role in the urinary concentration and volume regulation. Electrically silent transporter system.

      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 Etacrynic acid 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.
