Pharmacology - Beta-Blockers:
Beta-blockers are a group of drugs which target specific receptors in the human body, inhibiting the ability of these receptors to bind norepinephrine; list four targets in the cardiovascular system for this group of drugs and clearly and concisely explain their mechanism of action for lowering blood pressure:
I'm having a hard time figuring this out, any help is greatly appreciated. Thank you so much!!
Beta blockers play an important role in cardio vascular diseases including hypertension and heart failures.
Beta blockers bind with beta adreno receptors and further they block the binding of norepinephrine and epinephrine.Because of this normal sympathetic functions gets affected.
Beta blockers vs Hypertension : Beta blockers decrease arterial blood pressure by reducing cardiac output.Beta blockers slows the heart rate and makes contractions easier. Blood pressure falls down as heart pumps smaller amount of blood.These drugs actually increase the life span of people with angina, Heart failures, arrhythmias and also atrial fibrillation.
Examples of Beta blockers : Metoprolol, Atenolol, Propranalol, Cardevolol etc.
Oral beta blockers are also very effective in treating atrial fibrillation by reducing ventricular rates.They actually alter the electrical signals in the heart and reduces the rhythm thus reducing the stress.Beta blockers also helps to treat systolic heart failure by reducing heart rate which makes the heart to take more time to fill the blood which reduces the chances of heart failure.
