rifAMPin calaspargase pegol

Applies to: rifampin and calaspargase pegol

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

rifAMPin food

Applies to: rifampin

GENERALLY AVOID: Concurrent use of rifampin in patients who ingest alcohol daily may result in an increased incidence of hepatotoxicity. The increase in hepatotoxicity may be due to an additive risk as both alcohol and rifampin are individually associated with this adverse reaction. However, the exact mechanism has not been established.

ADJUST DOSING INTERVAL: Administration with food may reduce oral rifampin absorption, increasing the risk of therapeutic failure or resistance. In a randomized, four-period crossover phase I study of 14 healthy male and female volunteers, the pharmacokinetics of single dose rifampin 600 mg were evaluated under fasting conditions and with a high-fat meal. Researchers observed that administration of rifampin with a high-fat meal reduced rifampin peak plasma concentration (Cmax) by 36%, nearly doubled the time to reach peak plasma concentration (Tmax) but reduced overall exposure (AUC) by only 6%.

MANAGEMENT: The manufacturer of oral forms of rifampin recommends administration on an empty stomach, 30 minutes before or 2 hours after meals. Patients should be encouraged to avoid alcohol or strictly limit their intake. Patients who use alcohol and rifampin concurrently or have a history of alcohol use disorder may require additional monitoring of their liver function during treatment with rifampin.

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.
