Drugs that make blood pressure rise rapidly are mainly adrenergic agonists, which can be categorized into alpha, beta, alpha and beta agonists.
1. Alpha agonists: the representative drug is norepinephrine, which can agonize the α1 receptor of blood vessels, making blood vessels constrict. In small doses, cardiac excitation mainly increases systolic blood pressure, and in large doses, both systolic and diastolic blood pressure increase, which can be used for diseases such as neurogenic shock.
2. β-agonists: the representative drug is isoprenaline, which can make the heart excited and peripheral vasodilatation, and make the systolic blood pressure rise, and can be used in cardiac arrest, atrioventricular conduction block, and so on.
3. α and β agonists: the representative drug is epinephrine, at low doses, systolic blood pressure rises, diastolic blood pressure remains unchanged or slightly decreases; at high doses, both systolic blood pressure and diastolic blood pressure rise, which can be used for cardiac arrest, anaphylactic shock, etc..
All of the above drugs should be used under the supervision of a physician.
