Question 1

What is the Meaning of Antihypertensive Drugs?

Accepted Answer

Antihypertensive drugs are a class of pharmaceutical agents specifically designed to lower elevated blood pressure, thereby mitigating the health risks associated with hypertension. These medications target various physiological mechanisms involved in blood pressure regulation to achieve their therapeutic effect.

Question 2

What is the Context of Antihypertensive Drugs?

Accepted Answer

These agents function within the cardiovascular system, directly influencing components such as vascular tone, cardiac output, and renal fluid balance. Their action helps to restore hemodynamic equilibrium, reducing the chronic strain on arterial walls and vital organs like the heart, kidneys, and brain.

Question 3

What is the Significance of Antihypertensive Drugs?

Accepted Answer

The clinical significance of antihypertensive drugs is substantial, as their appropriate use directly reduces the incidence of cardiovascular events, including myocardial infarction, stroke, and heart failure. Effective blood pressure management improves patient prognosis and quality of life, preventing organ damage and extending healthy lifespan.

Question 4

What is the Mechanism of Antihypertensive Drugs?

Accepted Answer

Antihypertensive drugs operate through diverse mechanisms, including blockade of the renin-angiotensin-aldosterone system (RAAS) by ACE inhibitors or ARBs, direct vasodilation via calcium channel blockers, reduction of cardiac output through beta-blockade, or increasing sodium and water excretion with diuretics. Each class interacts with specific receptors or enzymes to achieve blood pressure reduction.

Question 5

What is the Application of Antihypertensive Drugs?

Accepted Answer

Clinically, antihypertensive drugs are prescribed for the long-term management of primary and secondary hypertension, often initiated based on blood pressure readings exceeding established thresholds. Treatment protocols frequently involve a stepped-care approach, starting with a single agent and escalating to combination therapy as needed to achieve target blood pressure goals.

Question 6

What is the Metric of Antihypertensive Drugs?

Accepted Answer

The effectiveness of antihypertensive therapy is primarily monitored through regular blood pressure measurements, both in the clinical setting and through home monitoring. Additionally, assessments of end-organ function, such as kidney function tests (serum creatinine, GFR) and urine albumin-to-creatinine ratio, along with electrocardiograms, help evaluate treatment impact and detect potential complications.

Question 7

What is the Risk of Antihypertensive Drugs?

Accepted Answer

Potential risks associated with antihypertensive drugs include adverse effects like orthostatic hypotension, electrolyte imbalances, renal dysfunction, and specific class-related side effects such as cough with ACE inhibitors or ankle edema with calcium channel blockers. Careful patient selection, dose titration, and ongoing monitoring are essential to minimize these risks and ensure patient safety.
