Therapeutic Indications Of Atenolol

Question 1. Discuss Hypertension Mode Of Action And Therapeutic Indications Of Atenolol.
Answer:

Atenolol is a selective beta blocker.

Therapeutic Indications Of Atenolol

• In young hypertensive patients who have high renin levels.
• In patients with angina pectoris.
• In patients with postmyocardial infarction.
• In patients with migraine.
• In patients with psychosomatic disorders.
• It is indicated in patients who receive vasodilators to counteract reflex tachycardia.
• It is indicated to subside symptoms of alcohol withdrawal.
• It is also indicated to treat the symptoms of grave disease till anti-thyroid medication produces its effect.

Question 2. Explain The Pharmacological Basis For Beta Blockers In Hypertension And Angina Pectoris.
Answer:

Pharmacological Basis For Beta Blockers In Hypertension

When a beta blocker is administered total peripheral resistance is increased initially and cardiac output is reduced, so there is little decrease in blood pressure.

With continued treatment resistance vessels gradually adapt to chronically reduced cardiac output so that total peripheral resistance decreases and both systolic and diastolic blood pressure falls.

Pharmacological Basis For Beta Blockers In Angina Pectoris

Beta-blockers reduce cardiac work and oxygen consumption. Total coronary flow is reduced but this is largely restricted affected.

The main overall effect of beta blockers in angina pectoris is that these drugs improve oxygen supply/demand status and exercise tolerance is increased.
