Patients with hypertension with slow heart rate can choose diphenhydramine drugs, such as nifedipine, amlodipine and felodipine. Since one of the side effects of diphenhydramine is an increase in heart rate, patients with hypertension with a slow heart rate can take these drugs to relieve the slow heart rate and also have the effect of lowering blood pressure. Patients with hypertension with slow heart rate must be careful in the choice of antihypertensive drugs, or try to avoid the use of bisoprolol or metoprolol drugs, because in addition to lowering blood pressure, these drugs also have the effect of lowering the heart rate. For the priligy class such as enalapril, captopril and irbesartan or hydrochlorothiazide, there are no contraindications for patients with hypertension and slow heart rate, and they can be applied normally.
