Why some drugs require coagulation profile monitoring and some not? Which ? And Why?

[@Foxterrier]

Drugs like DOACs (Dabigatran, Rivaroxaban, Apixaban) and LMWH (Enoxaparin) have predictable absorption, distribution, metabolism, and excretion profiles, leading to stable anticoagulant effects at fixed doses. In contrast to this drugs like warfarin / heparin have a very narrow therapeutic index, meaning that small changes in dose or drug levels can result in under-anticoagulation (leading to clotting) or over-anticoagulation (leading to bleeding) + some drugs have significant variability between patients due to genetic factors (e.g., warfarin metabolism varies due to CYP2C9 and VKORC1 genotypes).
