Issue 1 Retail health care providers are in an optimal position to monitor for drug interactions between warfarin and antibiotics because 80% to 90% of all
Jan 1, 2011 • The drug interaction between warfarin and erythromycin is not well known
Inhibition or induction of cytochrome P450 drug metabolizing isoenzymes is the most common mechanism by which clinically important drug interactions occur

Copper oxide nanoparticles (NCuO) have emerged as an alternative to pesticides due to their antifungal effect against various phytopathogens
Food intake does not appear to exert effects on serum concentrations of erythromycin
It inhabits the production of certain blood clotting proteins by the liver
This type of inhibition can cause interactions with drugs such as omeprazole, paroxetine, macrolide antibiotics, or mirabegron

5-7 These case reports were reviewed, and the issue of infectioninduced changes in warfarin discussed in a brief review
Fluconazole (Diflucan) - This popular antifungal can wreak havoc on your patient’s INR
Of the total drug interactions, 141 are major, 427 are moderate, and 70 are minor
Mechanism of action — Warfarin and related vitamin K antagonists (VKAs) block the function of the vitamin K epoxide reductase complex in the liver, leading to depletion of the reduced form of vitamin K that serves as a cofactor for gamma carboxylation of vitamin K-dependent coagulation factors [ 1 ]
Warfarin has >200 identified drug interactions, some with limited supporting evidence, 7,8 and therefore, the clinician must determine which interactions are clinically relevant and prudent to act on
