Epitol and Letermovir
Determining the interaction of Epitol and Letermovir and the possibility of their joint administration.
In the database of official manuals used in the service creation an interaction registered by statistical results of studies was found, which can either lead to negative consequences for the patient health or strengthen a mutual positive effect. A doctor should be consulted to address the issue of joint drug administration.
Consumer:Consumer information for this interaction is not currently available.GENERALLY AVOID: Coadministration with inducers of the P-glycoprotein (P-gp) efflux transporter and/or the uridine diphosphate glucuronosyltransferase (UGT) enzymes may decrease the plasma concentrations of letermovir according to the product labeling. Because letermovir is a substrate of P-gp and UGT 1A1 and 1A3, induction of the efflux transporter and metabolic enzymes may theoretically increase the clearance of letermovir. Concomitant use of rifampin initially resulted in a clinically insignificant increase in letermovir plasma concentrations (due to inhibition of organic anion transporting polypeptide [OATP] 1B1/3 and/or P-gp), followed by clinically significant decreases in letermovir plasma concentrations with continued rifampin coadministration (due to induction of P-gp/UGT). MANAGEMENT: Letermovir product labeling recommends avoiding concomitant use with inducers of P-gp and/or UGT. References Cerner Multum, Inc. "UK Summary of Product Characteristics."
