Study Notes

Antihypertensive Drugs

Antihypertensive drugs are often combined for a synergistic effect, as they affect different areas of blood pressure control.
Hypertension, or high blood pressure, occurs when blood pressure is consistently too high.
90% of hypertension cases have no known cause and are called essential hypertension.
Antihypertensive agents work by altering the body's regulating mechanisms responsible for maintaining normal blood pressure.
These regulating mechanisms include the baroreceptors and the renin-angiotensin-aldosterone system.
Individuals respond differently to antihypertensive agents because hypertension is multifactorial.
The presence of comorbidities, such as diabetes and myocardial infarction, may impact the suitability of certain antihypertensives for treatment.
