- Magtrate (magnesium gluconate)
Interactions between your drugs
magnesium gluconate dolutegravir
Applies to: Magtrate (magnesium gluconate) and abacavir / dolutegravir / lamivudine
ADJUST DOSING INTERVAL: Coadministration with medications containing polyvalent cations such as aluminum, calcium, iron, or magnesium may decrease the oral bioavailability of dolutegravir. The mechanism of interaction has not been established. In 16 study subjects, administration of a single 50 mg dose of dolutegravir simultaneously with an antacid (Maalox) decreased dolutegravir peak plasma concentration (Cmax), systemic exposure (AUC) and trough plasma concentration (Cmin; 24 hours post-dose) by 72%, 74% and 74%, respectively, compared to administration without the antacid. When the antacid was administered 2 hours after dolutegravir, the Cmax, AUC and Cmin of dolutegravir decreased by just 18%, 26% and 30%, respectively. Administration of single-dose dolutegravir simultaneously with a multivitamin (One-A-Day) decreased the Cmax, AUC and Cmin of dolutegravir by 35%, 33% and 32%, respectively.
MANAGEMENT: Dolutegravir should be administered 2 hours before or 6 hours after medications containing polyvalent cations such as antacids, laxatives, or mineral supplements.

Drug and food interactions
dolutegravir food
Applies to: 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.
