      Drug Name Eprosartan Lofexidine
      Mechanism Antihypertensive agent
Angiotensin II receptor  Antagonist 		Hypotensive effects
Alpha-2 adrenergic receptor  Agonist
      Key Mechanism Factor 1
Factor Name Angiotensin II receptor Structure Sequence
Protein Family G-protein coupled receptor 1 family
Protein Function
Receptor for angiotensin II. Mediates its action by association with G proteins that activate a phosphatidylinositol-calcium second messenger system.; (Microbial infection) During SARS coronavirus-2/SARS-CoV-2 infection, it is able to recognize and internalize the complex formed by secreted ACE2 and SARS-CoV-2 spike protein through DNM2/dynamin 2-dependent endocytosis.

      Key Mechanism Factor 2
Factor Name Adrenergic receptor alpha-2 Structure Sequence
Protein Family G-protein coupled receptor 1 family
Protein Function
Alpha-2 adrenergic receptors mediate the catecholamine-induced inhibition of adenylate cyclase through the action of G proteins. The rank order of potency for agonists of this receptor is oxymetazoline > clonidine > epinephrine > norepinephrine > phenylephrine > dopamine > p-synephrine > p-tyramine > serotonin = p-octopamine. For antagonists, the rank order is yohimbine > phentolamine = mianserine > chlorpromazine = spiperone = prazosin > propanolol > alprenolol = pindolol.

      Mechanism Description
  • Additive hypotensive effects by the combination of Eprosartan and Lofexidine 

Recommended Action
      Management Hemodynamic responses should be monitored during coadministration of lofexidine with antihypertensive agents, especially during the first few weeks of therapy.
