Interactions between your drugs

Moderate

atovaquone pegaspargase

Applies to: Mepron (atovaquone) and pegaspargase

MONITOR: Concomitant use of asparaginase with other hepatotoxic agents may potentiate the risk of liver injury. Asparaginase-associated hepatotoxicity has been reported more commonly in adults than in children and has been strongly associated with obesity. Hepatomegaly, acute severe hepatotoxicity, and fatal liver failure have been reported with asparaginase treatment in adults. Also, asparaginase may increase the toxicity of drugs bound to plasma proteins or metabolized by the liver.

MANAGEMENT: The risk of additive hepatotoxicity should be considered when asparaginase is used with other hepatotoxic agents (e.g., alcohol, androgens, antituberculosis agents, azole antifungal agents, ACE inhibitors, macrolide antibiotics, nonsteroidal anti-inflammatory agents, nucleoside reverse transcriptase inhibitors, sulfonamides, thiazolidinediones, and statins). Liver function tests should be monitored at regular intervals during asparaginase treatment with or without other hepatotoxic drugs. Patients should be advised to seek medical attention if they experience potential symptoms of hepatotoxicity such as right upper quadrant pain, increasing abdominal size, fever, rash, itching, anorexia, nausea, vomiting, fatigue, malaise, dark urine, pale stools, and jaundice.

Drug and food interactions

Moderate

atovaquone food

Applies to: Mepron (atovaquone)

ADJUST DOSING INTERVAL: Food, particularly high-fat food, significantly enhances the oral absorption and bioavailability of atovaquone. In 16 healthy volunteers, administration of a single 750 mg dose of atovaquone suspension following a standard breakfast (23 g fat: 610 kCal) resulted in an approximately 3.4-fold increase in the mean peak plasma concentration (Cmax) and a 2.5-fold increase in the mean area under the plasma concentration-time curve (AUC) of atovaquone compared to administration following an overnight fast. In a study consisting of 19 HIV-infected volunteers receiving atovaquone suspension 500 mg/day, Cmax and AUC of atovaquone increased by 72% and 66%, respectively, in the fed state relative to the fasting state.

MANAGEMENT: To ensure maximal oral absorption, atovaquone products (suspension, tablet, or in combination with proguanil) should be administered with a meal or milky drink, or enteral nutrition at the same time(s) each day. Because plasma atovaquone concentrations have been shown to correlate with the likelihood of successful treatment and in some cases, survival, alternative therapies may be appropriate for patients who have difficulty taking atovaquone 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.
