Questions and Answers

Explain the difference in anti-blood clotting mechanism between apixaban and acetylsalicylic acid (aspirin).

Apixaban primarily impacts the coagulation cascade by inhibiting specific clotting factors, while aspirin targets platelet function and aggregation via COX enzymes.

Why are people at higher risk of bleeding when combining apixaban with medicinal products that inhibit CYP3A4 and P-glycoproteins?

Combining apixaban with drugs that inhibit CYP3A4 or P-glycoprotein can lead to higher apixaban levels in the body, slowing down the breakdown of apixaban and prolonging its anticoagulant action, potentially increasing the risk of bleeding.

How does apixaban work as a directly acting anticoagulant?

Apixaban works as a directly acting anticoagulant, making it easier for the blood to flow through the body and preventing blood clots.

What is a common side effect associated with the mechanism of action of apixaban?

<p>A common side effect associated with the mechanism of action of apixaban is an increased risk of bleeding or hemorrhage.</p> Signup and view all the answers

What is P-glycoprotein and how does it relate to the action of apixaban?

<p>P-glycoprotein is a protein that helps remove substances, including medications, from cells. Apixaban is a substrate for P-glycoprotein, meaning it is pumped out of cells by this protein. Combining with drugs that inhibit P-glycoprotein can prolong the anticoagulant action of apixaban.</p> Signup and view all the answers

What is the mechanism of action of angiotensin II receptor blockers (ARBs) like valsartan?

<p>Antagonist of the AT1 receptor, leading to vasodilation and reduced aldosterone production, resulting in lower blood pressure.</p> Signup and view all the answers

What are the main indications for the use of angiotensin II receptor blockers (ARBs) like valsartan?

<p>Hypertension and heart failure.</p> Signup and view all the answers

How can the side-effect of dizziness from valsartan's mechanism of action be explained?

<p>Orthostatic hypotension and reduced capability for peripheral vasoconstriction, leading to lower blood pressure.</p> Signup and view all the answers

What is the difference in mechanism of action between ACE inhibitors and ARBs in the context of treating hypertension?

<p>ACE inhibitors inhibit the formation of angiotensin II, while ARBs inhibit the actions of angiotensin II mediated via the AT1 receptor. ACE inhibitors have a wider range of actions.</p> Signup and view all the answers

Explain how ARBs like valsartan lead to increased urinary water loss and lowered blood pressure.

<p>By reducing aldosterone production, lowering sodium re-uptake in the kidney, and leading to vasodilation.</p> Signup and view all the answers
