ACEI drugs tend to cause irritating dry cough, mainly because ACEI drugs lead to abnormal metabolism of prostaglandins and are prone to this type of complication, such as captopril and enalapril. If the patient cannot tolerate irritating cough, it is recommended to switch to another drug, such as ARB drugs, like Irbesartan and Valsartan, or calcium channel antagonists, such as Nifedipine and Amlodipine, which can help prevent irritating dry cough. People with hypertension who have an irritating dry cough should choose to gradually discontinue the drug if their blood pressure is well controlled, to prevent excessive fluctuations in blood pressure from affecting the patient’s blood pressure control after immediate discontinuation, and to keep their blood pressure below 140/90 mmHg and actively improve their poor lifestyle habits.
