| Mechanism 1 |
Antihypertensive agent Angiotensin II receptor Antagonist |
Antihypertensive agent | |||||||
| 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.

|---|---|---|---|---|---|---|---|---|---|
| Management | Caution and close monitoring for altered efficacy and safety are recommended if patients receive apomorphine with an antihypertensive agent or vasodilator. Patients should be made aware of the possible side effects (e.g., dizziness, lightheadedness, orthostasis) and be cautioned about driving, operating machinery, or performing other hazardous tasks. They should also be advised to avoid rising abruptly from a sitting or recumbent position and to contact their physician if they experience symptoms of hypotension such as dizziness, lightheadedness, or fainting. | ||||||||
