Elvitegravir/cobicistat/emtricitabine/tenofovir alafenamide (EVG/COBI/FTC/TAF) is specified in its package insert to be taken with food to obtain sufficient exposure of EVG. It has been reported that a nutritional protein-rich drink shows comparable pharmacokinetics (PK) of EVG to those with a standard breakfast. In this study, the PK profiles of EVG and COBI were evaluated by administration of a single dose of EVG/COBI/FTC/TAF, after ingestion of either a nutritional protein-rich drink, milk, or apple juice. The geometric means for Cmax and AUCinf of EVG following milk ingestion slightly decreased by 21% and 14%, respectively, and those following apple juice ingestion decreased by 67% and 61%, respectively, compared with a nutritional protein-rich drink. There were no differences in any PK parameters of COBI. Therefore, taking EVG/COBI/FTC/TAF after milk or apple juice ingestion appeared to be not appropriate. However, for plasma trough concentrations (Ctau ), it is known that Ctau is best correlated with the efficacy of EVG. The mean C24 of EVG after milk ingestion was 620.6 ng/mL, which was more than 10-fold the protein binding-adjusted 95% inhibitory concentration. With all the above considerations, it was concluded that taking EVG/COBI/FTC/TAF with milk could be an option to maintain sufficient plasma concentrations of EVG.

An acute, often fatal disease caused by the ingestion of milk, milk products, or the flesh of cattle or sheep which have a disease known as trembles. It is marked by weakness, anorexia, vomiting, constipation, and sometimes muscular tremors. It is caused by poisoning by white snakeroot (Eupatorium rugosum) and the rayless goldenrod (Haplopappus heterophyllus). (From Dorland, 27th ed)
4-Hydroxy-4H-furo(3,2-c)pyran-2(6H)-one. A mycotoxin produced by several species of Aspergillus and Penicillium. It is found in unfermented apple and grape juice and field crops. It has antibiotic properties and has been shown to be carcinogenic and mutagenic and causes chromosome damage in biological systems.
Allergic reaction to milk (usually cow's milk) or milk products. MILK HYPERSENSITIVITY should be differentiated from LACTOSE INTOLERANCE, an intolerance to milk as a result of congenital deficiency of lactase.
