Interactions between your drugs

Moderate

atazanavir avatrombopag

Applies to: atazanavir and avatrombopag

MONITOR: Concomitant use of avatrombopag with strong CYP450 3A4/5 or CYP450 2C9 inhibitors may increase the systemic exposure (AUC) to avatrombopag. The increase in avatrombopag exposure is not expected to have a clinically important effect on platelet counts in patients with chronic liver disease scheduled to undergo a procedure due to the 5-day treatment duration .

MANAGEMENT: No dose adjustment is recommended; however, it may be advisable to monitor the platelet count more closely.

Drug and food interactions

Moderate

atazanavir food

Applies to: atazanavir

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.

avatrombopag food

Applies to: avatrombopag

ADJUST DOSING INTERVAL: Food reduces the variability in oral absorption and bioavailability of avatrombopag. According to the product labeling, avatrombopag peak plasma concentration (Cmax) and systemic exposure (AUC) were not affected when administered with either a low-fat (500 calories; 3 g fat, 15 g proteins, 108 g carbohydrates) or high-fat (918 calories; 59 g fat, 39 g proteins, 59 g carbohydrates) meal. However, the variability of avatrombopag exposure was reduced by 40% to 60% with food, and the time to reach Cmax was delayed by 0 to 2 hours relative to the fasted state.

MANAGEMENT: To ensure consistent absorption and plasma drug levels, avatrombopag should be taken with food.

Drug Interaction Classification

These classifications are only a guideline. The relevance of a particular drug interaction to a specific individual is difficult to determine. Always consult your healthcare provider before starting or stopping any medication.
Major Highly clinically significant. Avoid combinations; the risk of the interaction outweighs the benefit.
Moderate Moderately clinically significant. Usually avoid combinations; use it only under special circumstances.
Minor Minimally clinically significant. Minimize risk; assess risk and consider an alternative drug, take steps to circumvent the interaction risk and/or institute a monitoring plan.
Unknown No interaction information available.
