Final answer:
Anticoagulants, certain antifungal, and antiviral drugs can potentially lead to a pulmonary embolus, highlighting the importance of careful patient monitoring by healthcare providers.
Step-by-step explanation:
The class of drugs that can lead to a pulmonary embolus includes anticoagulants and some antifungal and antiviral medications. Among anticoagulants, drugs like Rivaroxaban (Xarelto), Dabigatran (Pradaxa), Apixaban (Eliquis), Heparin, and Warfarin (Coumadin) are used to prevent blood clots, but if not managed correctly, they can also contribute to their formation. Additionally, the allylamines class of antifungal drugs and the antiviral drug amantadine also have the potential to affect clotting mechanisms, potentially leading to adverse events such as a pulmonary embolism. It is essential for healthcare providers to monitor patients on such medications carefully to minimize this risk.
