Drug and food interactions

Moderate

ganciclovir food

Applies to: ganciclovir

ADJUST DOSING INTERVAL: Food delays but enhances the oral absorption and bioavailability of ganciclovir capsules, possibly due to prolongation of gastrointestinal transit time. In 20 HIV- and CMV-seropositive subjects, ganciclovir dosing (1000 mg every 8 hours) following a standardized high-fat breakfast increased the mean steady-state peak plasma concentration (Cmax) and area under the concentration-time curve (AUC) of ganciclovir by an average of 15% and 22%, respectively, compared to dosing after an overnight fast. The time to reach peak plasma concentration (Tmax) was prolonged from 1.8 to 3 hours. In another study of 15 such patients, administration of ganciclovir (2000 mg) within 30 minutes following a high-fat breakfast increased the Cmax and AUC an average of 111% and 114%, respectively, compared to administration in the fasting state (i.e. at least 1 hour before or 2 hours after a meal or snack). Over the total day of dosing (2000 mg orally three times a day), there was a mean increase of 48% and 97% in Cmax and AUC, respectively, and a 36% decrease in half-life during administration with meals.

MANAGEMENT: To ensure maximal oral absorption, oral ganciclovir should be administered with or immediately after a meal.

Moderate

nalbuphine food

Applies to: Nubain (nalbuphine)

GENERALLY AVOID: Ethanol may potentiate the central nervous system (CNS) depressant effects of opioid analgesics. Concomitant use may result in additive CNS depression and impairment of judgment, thinking, and psychomotor skills. In more severe cases, hypotension, respiratory depression, profound sedation, coma, or even death may occur.

MANAGEMENT: Concomitant use of opioid analgesics with ethanol should be avoided.

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.
