| Mechanism |
Antihypertensive agent Angiotensin II receptor Antagonist |
Hypotensive effects Phosphodiesterase 5A 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 | PDE5A | ||||||||
| Uniprot ID | PDE5A_HUMAN | ||||||||
| KEGG Pathway | hsa:8654 | ||||||||
| Protein Family | Cyclic nucleotide phosphodiesterase family | ||||||||
| Protein Function |
Plays a role in signal transduction by regulating the intracellular concentration of cyclic nucleotides. This phosphodiesterase catalyzes the specific hydrolysis of cGMP to 5'-GMP (PubMed:9714779, PubMed:15489334). Specifically regulates nitric-oxide-generated cGMP (PubMed:15489334).

| Recommended Action | |||||||||
|---|---|---|---|---|---|---|---|---|---|
| Management | Caution is advised if PDE5 inhibitors are prescribed in combination with antihypertensive agents. Patients receiving the combination should be advised to avoid rising abruptly from a sitting or recumbent position, especially following treatment initiation or a dosage increase, and to contact their doctor if they experience symptoms of hypotension such as dizziness, lightheadedness, fainting, or tachycardia. | ||||||||
