Vitamin K, a fat-soluble vitamin synthesized by plants, is found in large quantities within green leafy vegetables, such as collard, mustard, turnip and spinach. These greens are commonly cooked with fat to enhance flavor. The vitamin K in these greens can leach out during cooking into the liquid portion of the pot, which is referred to as potlicker. Vitamin K activates clotting factors (II, VII, IX, and X,), which can lead to the formation of a thromboembolism (blood clot). People at a higher risk of forming blood clots are often prescribed warfarin, an anti-coagulant that acts as a competitive inhibitor …

The goal of the in vitro research was to evaluate the potential for inhibition of warfarin protein binding by tizoxanide. Warfarin was of particular interest for the present investigation because it has been shown to be highly bound to plasma proteins and is a narrow therapeutic index drug. Tizoxanide is an active metabolite of an anti-infective prodrug nitazoxanide and also highly protein-bound medication. Both drugs are expected to be co-administered clinically. Protein binding of warfarin was investigated using a centrifugal ultrafiltration technique. Co-administration of tizoxanide significantly inhibited protein binding of warfarin for all concentrations tested. Tizoxanide increased free fraction (fu) …
