The choice of which antihypertensive drug is appropriate for patients with psoriasis is mainly based on whether there is a combination of other diseases or other symptoms. If hypertension is accompanied by tachycardia, beta-blockers can be given; if combined with diabetes, angiotensin-converting enzyme inhibitors and angiotensin II receptor antagonists can be given; if combined with cardiac insufficiency, diuretics can be given. Common antihypertensive drugs for hypertension include diuretics, β-receptor antagonists, calcium channel blockers, angiotensin-converting enzyme inhibitors, angiotensin II receptor antagonists and so on. 1. Diuretics: mainly include thiazides, diuretics and potassium-sparing diuretics, thiazides are the most common, commonly used hydrochlorothiazide; diuretics are not suitable for patients with renal insufficiency, potassium-sparing diuretics can cause hyperkalemia, and should be used with caution in patients with renal insufficiency. 2. β-receptor antagonists: commonly used drugs include propranolol, metoprolol, etc., which can inhibit myocardial contractility, slow down the heart rate, so as to play a role in lowering blood pressure. 3. Calcium channel blockers: including dihydropyridines such as nifedipine and non-dihydropyridines such as verapamil, etc., which have rapid onset of antihypertensive effect and obvious antihypertensive efficacy. 4. Angiotensin-converting enzyme inhibitors: including captopril and enalapril, etc., slow onset of antihypertensive effect, hyperkalemia, pregnant women, bilateral renal artery stenosis patients are prohibited. 5. Angiotensin II receptor antagonist: mainly including chlorosartan and valsartan and other drugs, the effect of lowering blood pressure is slow but smooth, with fewer adverse reactions. Psoriasis patients with hypertension should use drugs under the guidance of doctors.
