Therefore, the main action of antihypertensive agents is to alter the body’s regulating mechanisms (e.g. baroreceptors, renin-angiotensin-aldosterone system, etc.) responsible for maintaining normal blood pressure.  Different people have different responses towards hypertensive agents because hypertension is multifactorial. For an instance, the presence of comorbidities (e.g. diabetes, myocardial infarction, etc.) may make some antihypertensives not suitable for treatment. Hypertension elevated blood pressure - is a serious medical condition that significantly increases the risks of heart, brain, kidney and other diseases. Types 1. essential hypertension: there is elevated total peripheral resistance. Also, the organs are perfused effectively and people with essential hypertension usually exhibit no symptoms. It is also the reason why hypertension is tagged as the “silent killer.” 2. secondary hypertension is characterized by elevated blood pressure due to a known cause. For example, a tumor in the adrenal medulla called phaeochromocytoma can cause the organ to release a high amount of catecholamines, which greatly increase blood pressure.
