Direct Oral Anticoagulants: An Overview of Indications, Pharmacokinetics, Comorbidities, and Perioperative Management.

Direct oral anticoagulants (DOACs) have catalyzed a significant paradigm shift in the landscape of anticoagulant therapy, emerging as pivotal agents for the prevention of stroke in atrial fibrillation and venous thromboembolism. Although the absolute advantages of DOACs over vitamin K antagonists (VKAs) may appear modest, clinical guidelines advocate for their preference across various indications, attributing this endorsement to their ease of administration and heightened safety. DOACs find application in preventing and treating diverse cardiovascular conditions. With the progressive expansion of DOAC utility, clinicians encounter intricate decisions concerning the selection of appropriate agents, determination of optimal treatment duration, and utilization within specialized patient subgroups. Extensive evidence has substantiated the noninferiority or superiority of DOACs compared with VKAs in both prophylaxis and treatment of thromboembolic events. Notably, routine monitoring to evaluate treatment efficacy is not mandated for DOACs; however, they exhibit interactions with co-administered drugs and exert influence on functional coagulation assessments. This review aims to synthesize existing literature, encompassing the delineation of appropriate clinical indications, tailored employment in patients with specific concurrent conditions, needs in monitoring parameters, seamless transitions during shifts between anticoagulant regimens, and a glimpse into forthcoming perspectives in this evolving field.
