atazanavir ↔ food
Moderate Food Interaction
Consumer information for this interaction is not currently available.
ADJUST DOSING INTERVAL: Administration of atazanavir with food enhances oral bioavailability and reduces pharmacokinetic variability. According to the manufacturer, administration with a light meal increased the peak plasma concentration (Cmax) and area under the concentration-time curve (AUC) of a single 400 mg dose of atazanavir by 57% and 70%, respectively, relative to the fasting state. Administration with a high-fat meal resulted in a mean increase of 35% in atazanavir AUC and no change in Cmax compared to fasting. The coefficient of variation of AUC and Cmax decreased by approximately one-half when given with either a light or high-fat meal compared to the fasting state.
MANAGEMENT: To ensure maximal oral absorption, atazanavir should be administered with or immediately after a meal.

High Cholesterol (Hyperlipoproteinemia, Hypertriglyceridemia, Sitosterolemia)
Moderate Potential Hazard, High plausibility
PIs - hyperlipidemia
Hyperlipidemia has been observed in 10% of patients receiving ritonavir during clinical trials. Increases of 30% to 40% from baseline have been reported for total cholesterol and 200% to 300% or more for triglycerides. These effects have also been reported during postmarketing experience with other protease inhibitors (PIs) but may be the most dramatic with ritonavir. The clinical significance of these elevations is unclear. Severe hyperlipidemia is known to sometimes cause pancreatitis. In addition, some patients have reportedly developed symptomatic atherosclerosis and coronary artery disease after initiating PI treatment. Patients with preexisting hyperlipidemia may require closer monitoring during PI therapy, and adjustments made accordingly in their lipid-lowering regimen. PI therapy should be administered cautiously in patients with coronary artery disease or a history of ischemic heart disease.
