Nisar Ahmed: The Evolution of Anticoagulation Therapy

Nisar Ahmed, Pharmacist at Zubair Pharmacy, shared a post on LinkedIn:

“70 years of warfarin vs the new generation.

Here’s why anticoagulation has changed forever.

Warfarin — blocks vitamin K clotting factors, needs constant INR monitoring, dozens of food and drug interactions.

Still irreplaceable for mechanical heart valves.

Apixaban (Eliquis) — directly inhibits Factor Xa, predictable, no monitoring, fewer interactions.

The landmark ARISTOTLE trial: 21% less stroke, 31% less major bleeding, 11% lower mortality vs warfarin in AF.

  • Mechanical heart valve? Stick with warfarin – DOACs are contraindicated.
  • Non-valvular AF or VTE? Apixaban is now the standard of care.
