Interactions between your drugs

Minor

dolutegravir sotorasib

Applies to: Triumeq PD (abacavir / dolutegravir / lamivudine) and sotorasib

Coadministration with inducers of UGT1A and CYP450 3A4 isoenzymes may decrease the plasma concentrations of dolutegravir, which is primarily metabolized by UGT1A1 with some contribution from CYP450 3A4. Dolutegravir is also a substrate of UGT1A3, UGT1A9, and P-glycoprotein in vitro. In 9 study subjects, administration of dolutegravir 50 mg once daily with rifabutin 300 mg once daily decreased dolutegravir trough plasma concentration (Cmin; 24 hours postdose) by 30% compared to administration without rifabutin. The clinical significance is unknown. Given the risk of reduced viral susceptibility and resistance development associated with subtherapeutic antiretroviral drug levels, caution may be advisable if dolutegravir is used in combination with mild or moderate UGT1A/CYP450 3A4 inducers.

Drug and food interactions

Minor

dolutegravir food

Applies to: Triumeq PD (abacavir / dolutegravir / lamivudine)

Food increases the extent of absorption and slows the rate of absorption of dolutegravir. When administered with a low-, moderate- or high-fat meal, dolutegravir peak plasma concentration (Cmax) increased by 46%, 52% and 67%, systemic exposure (AUC) increased by 33%, 41% and 66%, and time to reach Cmax (Tmax) increased from 2 hours to 3, 4 and 5 hours, respectively, compared to administration under fasted conditions. Dolutegravir may be taken with or without food.

Minor

sotorasib food

Applies to: sotorasib

Food does not appear to have a clinically significant effect on the oral bioavailability of sotorasib. When a 960 mg dose of sotorasib was administered to study patients with a high-fat, high-calorie meal (approximately 800 to 1000 calories; 150, 250, and 500 to 600 calories from protein, carbohydrate, and fat, respectively), sotorasib peak plasma concentration (Cmax) did not change while systemic exposure (AUC 0-24 hours) increased by 25% compared to administration under fasted conditions. Sotorasib can be administered with or without food at approximately the same time each day.

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.
