In the setting where anticoagulation therapy is necessary, clinicians are faced with the challenge of utilizing agents that inherently have a small therapeutic window and the ability for medication mishaps when not used appropriately. This risk is balanced against the need to prevent against or treat thrombosis, which can also have life altering consequences. This is an excellent resource for any pharmacist who wants to build expertise in caring for inpatients on anticoagulants. It also serves as a resource for a pharmacist who is tasked with teaching other pharmacists the clinical knowledge they need to manage patients on anticoagulants.
