Abstract:
Until about 4 years ago, warfarin was the only oral anticoagulant approved in the United States, and switching between oral anticoagulants has become an option since the emergence of the novel oral anticoagulants dabigatran, rivaroxaban, and apixaban. What are the reasons one may switch between the agents and how is this done? Discussed in this article are the 4 agents approved in the United States, their characteristics, reasons one may switch, and methods for conversion. After a thorough search of original trial data and recent expert review articles, we have summarized the most recent recommendations below and briefly discuss upcoming oral anticoagulants that show promise.
Insights
Switching between oral anticoagulants like warfarin, dabigatran, rivaroxaban, and apixaban is now possible. This article details reasons for switching and conversion methods for these anticoagulants.
Area of Science:
- Pharmacology
- Cardiology
- Internal Medicine
Background:
- Warfarin was the sole oral anticoagulant in the US until novel agents emerged.
- Novel oral anticoagulants (NOACs) include dabigatran, rivaroxaban, and apixaban.
- Switching between these anticoagulants is now a clinical consideration.
Purpose of the Study:
- To review the characteristics of four US-approved oral anticoagulants.
- To outline the indications for switching between these anticoagulant agents.
- To describe established methods for converting between oral anticoagulants.
Main Methods:
- Comprehensive literature search of original trial data.
- Review of recent expert consensus articles.
- Synthesis of current recommendations for anticoagulant switching.
Main Results:
- Detailed comparison of the four main oral anticoagulants.
- Identification of clinical scenarios necessitating anticoagulant switching.
- Summary of practical conversion strategies between agents.
- Brief overview of emerging oral anticoagulants.
Conclusions:
- Understanding anticoagulant characteristics is crucial for informed switching.
- Specific clinical factors guide the decision to switch anticoagulants.
- Established protocols facilitate safe and effective conversion between agents.
