Drug interactions

Major drug interactions

Major:

zinc sulfate elvitegravir

Applies to: Multiple Trace Element (trace elements) and elvitegravir
Adjust dosing interval

Coadministration with medications or supplements containing polyvalent cations such as zinc may decrease the plasma concentrations of integrase strand transfer inhibitors (INSTIs). The proposed mechanism involves chelation of the INSTI by polyvalent cations, forming a complex that is poorly absorbed from the gastrointestinal tract.

Management

If concomitant use is required, monitor for virologic efficacy and administer the INSTI at least 2 hours before or 6 hours after products containing polyvalent cations such as zinc.

Food/lifestyle interactions

Moderate food/lifestyle interactions

Moderate:

elvitegravir Food/Lifestyle

Applies to: elvitegravir
Adjust dosing interval

Food enhances the oral bioavailabilities of both elvitegravir and tenofovir. When a single dose of cobicistat/elvitegravir/emtricitabine/tenofovir (trade name Stribild) was given with a light meal (approximately 373 kcal; 20% fat), mean elvitegravir and tenofovir systemic exposures (AUCs) increased by 34% and 24%, respectively, relative to fasting conditions. When administered with a high-fat meal (approximately 800 kcal; 50% fat), the mean AUC of elvitegravir and tenofovir increased by 87% and 23%, respectively, relative to fasting conditions. The alterations in mean AUCs of cobicistat and emtricitabine were not clinically significant with either the light or high-fat meal.

Management

Cobicistat/elvitegravir/emtricitabine/tenofovir as a fixed-dose preparation should be administered once daily with food. Elvitegravir as a single-ingredient preparation should also be administered once daily with food.

Disease interactions

7 potential interactions Applies to: 4 conditions, including Liver Disease, Malabsorption Syndrome, Renal Dysfunction, and Biliary Obstruction.

Biliary Obstruction

Moderate:

Multiple Trace Element

The copper sulfate and manganese sulfate in Multiple Trace Element both have a moderate potential interaction with Biliary Obstruction.

The trace elements, copper and manganese, are excreted in the bile. Copper and manganese doses may need to be adjusted, reduced, or omitted in patients with liver disease or biliary obstruction.

Liver Disease

Major:

elvitegravir

Elvitegravir has a major potential interaction with Liver Disease.

The use of elvitegravir is not recommended for use in patients with severe hepatic impairment (Child-Pugh Class C). No dosage adjustment is required in patients with mild (Child-Pugh Class A) or moderate (Child-Pugh Class B) hepatic impairment.

Moderate:

Multiple Trace Element

The copper sulfate and manganese sulfate in Multiple Trace Element both have a moderate potential interaction with Liver Disease.

The trace elements, copper and manganese, are excreted in the bile. Copper and manganese doses may need to be adjusted, reduced, or omitted in patients with liver disease or biliary obstruction.

Malabsorption Syndrome

Moderate:

Multiple Trace Element

The chromic chloride hexahydrate, copper sulfate, manganese sulfate and zinc sulfate in Multiple Trace Element all have a moderate potential interaction with Malabsorption Syndrome.

The trace metals manganese, chromium, copper, selenium, and zinc are absorbed in the GI tract from dietary sources and following administration of oral supplements. GI absorption may be decreased in patients with malabsorption syndromes. Therefore, larger dosages may be required when these supplements are given orally. Parenteral administration may be appropriate.

Renal Dysfunction

Major:

elvitegravir

Elvitegravir has a major potential interaction with Renal Dysfunction.

The use of elvitegravir is not recommended in patients with severe renal impairment (estimated creatinine clearance below 30 mL per minute). No dosage adjustment is recommended in patients with estimated creatinine clearance greater than or equal to 30 mL per minute.

Moderate:

Multiple Trace Element

The manganese sulfate in Multiple Trace Element has a moderate potential interaction with Renal Dysfunction.

Manganese sulfate and manganese chloride preparations contain aluminum and may reach toxic levels with prolonged parenteral administration if kidney function is impaired. Premature neonates are particularly at risk because their kidneys are immature, and they require large amounts of calcium and phosphate solutions, which also contain aluminum. Patients with impaired kidney function, including premature neonates, who receive parenteral levels of aluminum at greater than 4 to 5 mcg/kg/day accumulate aluminum at levels associated with central nervous system and bone toxicity. Tissue loading may occur at even lower rates of administration. Caution is advised in patients with renal impairment, particularly in premature or neonates patients.

Moderate:

Multiple Trace Element

The chromic chloride hexahydrate and zinc sulfate in Multiple Trace Element both have a moderate potential interaction with Renal Dysfunction.

The trace metals, chromium and zinc, are excreted primarily in the urine. Selenium is partially excreted in the urine. Supplemental doses of these agents may need to be adjusted, reduced, or omitted in patients with renal dysfunction.

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.
