Oral anticoagulants are
medications that have an important place in the prevention and treatment of
thromboembolic events that can be seen in the course of many diseases today. Warfarin,
vitamin K antagonists are the most commonly known and used oral anticoagulants.
Drugs known as new oral anticoagulants have emerged due to the difficulties in
treatment and follow-up with warfarin. New oral anticoagulants exhibit
anticoagulant effects, disrupting the structure and function of some factors in
the coagulation cascade. There are many advantages such as monitorisation
requirement, constant dose use, patient compliance and ease of follow-up.
Meta-analyzes of large studies with new oral anticoagulants have shown that
they are non-inferior from warfarin in the prevention and treatment of
thromboembolic events, and even superior in some cases. Due to the ease of use
and advantages of these new agents, they have been rapidly spreading and taking
place in the prevention and treatment of embolism and ischemic events.
Therefore, the areas of use of these drugs, the location of treatment,
follow-up, possible side effects and most importantly management of bleeding
complications should be well known and applied.

Oral antikoagülanlar günümüzde
birçok hastalığın seyrinde görülebilen tromboembolik olayların engellenmesinde
ve tedavisinde çok önemli yeri olan ilaçlardır. Varfarin vitamin k
antagonistlerinden en çok bilinen ve kullanılan oral antikoagülanlardır.
Varfarin ile yapılan tedavi ve takiplerinde görülen zorluklarından dolayı yeni
oral antikoagülanlar olarak bilinen ilaçlar ortaya çıkmıştır. Yeni oral
antikogülanlar, koagülasyon kaskatında bazı faktörlerin yapı ve işlevlerini
bozarak antikoagülan etki göstermektedirler. Monitorizasyon gerektirmemesi,
sabit dozda kullanımı, hasta uyumu ve takip kolaylığı gibi birçok avantajları
vardır. Yeni oral antikoagülanlar ile yapılan büyük çalışmaların meta-analizlerine
bakıldığında, tromboembolik olaylardan koruma ve tedavisinde varfarinden
aşağıda kalmadığı, hatta bazı durumlarda üstün olduğu saptanmıştır. Bu
ajanların kullanım kolaylığı ve avantajlarından dolayı emboli ve iskemik
olaylardan korunma ve tedavisinde hızlı bir şekilde yer bulmuş ve
yaygınlaşmıştır. Bu nedenle bu ilaçların kullanımı, tedavideki yerleri,
takipleri, olası yan etkileri ve en önemlisi kanama komplikasyonlarının
yönetimi iyi bilinmeli ve uygulanmalıdır.
