The Expiring Patent: A Timeline for Apixaban's Global Availability
Apixaban, a popular anticoagulant medication, has been a game-changer in the treatment of atrial fibrillation and deep vein thrombosis. Developed by Pfizer, apixaban has been a commercial success, with its sales reaching billions of dollars worldwide. However, like all patented medications, apixaban's patent is set to expire, paving the way for generic versions of the drug to enter the market. In this article, we'll explore the timeline for apixaban's worldwide patent expiration and what it means for patients and pharmaceutical companies.
What is Apixaban?
Apixaban is a direct oral anticoagulant (DOAC) that works by inhibiting the activity of factor Xa, a key enzyme in the blood clotting process. It's used to prevent stroke and systemic embolism in patients with non-valvular atrial fibrillation, as well as to treat and prevent deep vein thrombosis and pulmonary embolism.

According to a report by Deloitte, the loss of patent protection can lead to a decline in sales and revenue for pharmaceutical companies. However, companies can mitigate this risk by developing new products and entering new markets.
