Warfarin, the traditional anticoagulant, has drawbacks such as narrow therapeutic range and frequent monitoring. Direct Oral Anticoagulants (DOAC) address these limitations. DOACs directly inhibit clotting factors, unlike warfarin which indirectly inhibits them. They are preferred due to easier administration, fewer interactions, and superior efficacy. Dabigatran, rivaroxaban, apixaban, and edoxaban are the available DOACs, each with unique attributes and considerations for administration and interactions.

What You Need to Know: Hemostasis
Hemostasis is achieved through primary and secondary stages. The coagulation cascade, part of secondary hemostasis, stabilizes the platelet plug. It consists of extrinsic, intrinsic, and common pathways, involving multiple clotting factors and calcium ions. Vitamin K is essential for the synthesis of some clotting factors. Each pathway is triggered by specific factors and leads to the activation of the common pathway, ultimately resulting in the formation of a stabilizing fibrin complex.
