Clinically, drugs that can cause an increase in blood pressure are mainly in the following categories: first, non-steroidal anti-inflammatory drugs, commonly used drugs including aspirin, meloxicam, celecoxib, ibuprofen, etc., which cause a decrease in prostaglandin synthesis through various pathways, causing vasoconstriction and water-sodium retention, resulting in an increase in blood pressure. Second, hormonal drugs, commonly used drugs such as dexamethasone, pine methylprednisolone, prednisone, etc., can lead to water and sodium retention, increase circulating blood volume, and eventually appear to increase blood pressure. Third, catecholamines, commonly used to raise blood pressure are epinephrine, norepinephrine, dopamine, through the excitation of α and β receptors, and ultimately constrict blood vessels, raising blood pressure. Fourth, other drugs used to raise high blood pressure, such as Midodrine, Chinese medicine, ginseng and wheat have a role in raising blood pressure.
