Additive hypotensive effects Click to Show/Hide Mechanism Graph

Drug Name		Eprosartan				Safinamide
Mechanism		Antihypertensive agent Angiotensin II receptor Antagonist				Hypotensive effects Monoamine oxidase-B selective Inhibitor
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.

		Gene Name		MAOB
		Uniprot ID		AOFB_HUMAN
		KEGG Pathway		hsa:4129
		Protein Family		Flavin monoamine oxidase family
		Protein Function		Catalyzes the oxidative deamination of primary and some secondary amines such as neurotransmitters, and exogenous amines including the tertiary amine, neurotoxin 1-methyl-4-phenyl-1,2,3,6-tetrahydropyridine (MPTP), with concomitant reduction of oxygen to hydrogen peroxide and participates in the metabolism of neuroactive and vasoactive amines in the central nervous system and peripheral tissues (PubMed:11134050, PubMed:8665924, PubMed:8316221, PubMed:11049757, PubMed:20493079). Preferentially degrades benzylamine and phenylethylamine (PubMed:11134050, PubMed:8665924, PubMed:8316221, PubMed:11049757, PubMed:20493079). Click to Show/Hide
Mechanism Description		Additive hypotensive effects by the combination of Eprosartan and Safinamide

Recommended Action
Management		Caution is advised during coadministration of MAOIs and other medications with hypotensive effects, especially during the first few weeks of treatment. Close monitoring for development of hypotension is recommended. Ambulatory patients should be advised to avoid rising abruptly from a sitting or recumbent position and to notify their physician if they experience dizziness, lightheadedness, syncope, orthostasis, or tachycardia.
