Blood pressure-lowering drugs can be divided into the following categories: 1. diuretics, mainly potassium-preserving diuretics and thiazides, which can reduce the volume of extracellular fluid through urination, thereby lowering blood pressure. 2. calcium channel blockers, such as nifedipine and verapamil, can reduce vascular resistance by blocking calcium ions from calcium channels into the blood vessels, thus playing a role in lowering blood pressure. 3. beta-receptor antagonists, mainly for middle-aged and young people or patients with combined heart failure. 4. 4, angiotensin-converting enzyme inhibitors, because the drug for reducing proteinuria and insulin resistance have better efficacy, so for patients with diabetes or obese hypertension is better. Therefore, the choice of drugs to lower blood pressure should be based on their own situation and condition.
