Interactions between your drugs

Moderate

oxyCODONE capivasertib

Applies to: Combunox (ibuprofen / oxycodone) and capivasertib

MONITOR: Coadministration with capivasertib may increase the plasma concentrations of drugs that are substrates of CYP450 3A4 via inhibition of the isoenzyme. Based on clinical studies and model-informed approaches, concomitant use of capivasertib and midazolam, a sensitive CYP450 3A4 substrate, increased midazolam systemic exposure (AUC) by 1.8-fold on day 4 and by 1.2-fold on day 7 of capivasertib treatment.

MANAGEMENT: Caution is advised if capivasertib is coadministered with CYP450 3A4 substrates, particularly sensitive substrates, or those with a narrow therapeutic range. Clinical and laboratory monitoring may be appropriate whenever capivasertib is added to or withdrawn from therapy. The prescribing information for concomitant medications may be consulted to assess the benefits versus risks of coadministration and for any dosage adjustments that may be required.

Drug and food interactions

Major

oxyCODONE food

Applies to: Combunox (ibuprofen / oxycodone)

GENERALLY AVOID: Alcohol may potentiate the central nervous system (CNS) depressant effects of opioid analgesics including oxycodone. 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.

GENERALLY AVOID: Grapefruit juice may increase the plasma concentrations of oxycodone. The proposed mechanism is inhibition of CYP450 3A4-mediated metabolism of oxycodone by certain compounds present in grapefruit, resulting in decreased formation of metabolites noroxycodone and noroxymorphone and increased formation of oxymorphone due to a presumed shifting of oxycodone metabolism towards the CYP450 2D6-mediated route. In 12 healthy, nonsmoking volunteers, administration of a single 10 mg oral dose of oxycodone hydrochloride on day 4 of a grapefruit juice treatment phase (200 mL three times a day for 5 days) increased mean oxycodone peak plasma concentration (Cmax), systemic exposure (AUC) and half-life by 48%, 67% and 17% (from 3.5 to 4.1 hours), respectively, compared to administration during an equivalent water treatment phase. Grapefruit juice also decreased the metabolite-to-parent AUC ratio of noroxycodone by 44% and that of noroxymorphone by 45%. In addition, oxymorphone Cmax and AUC increased by 32% and 56%, but the metabolite-to-parent AUC ratio remained unchanged. Pharmacodynamic changes were modest and only self-reported performance was significantly impaired after grapefruit juice. Analgesic effects were not affected.

MANAGEMENT: Patients should not consume alcoholic beverages or use drug products that contain alcohol during treatment with oxycodone. Any history of alcohol or illicit drug use should be considered when prescribing oxycodone, and therapy initiated at a lower dosage if necessary. Patients should be closely monitored for signs and symptoms of sedation, respiratory depression, and hypotension. Due to a high degree of interpatient variability with respect to grapefruit juice interactions, patients treated with oxycodone may also want to avoid or limit the consumption of grapefruit and grapefruit juice.

capivasertib food

Applies to: capivasertib

GENERALLY AVOID: Grapefruit juice may increase the plasma concentrations of capivasertib, which is primarily metabolized by CYP450 3A4. The proposed mechanism is inhibition of CYP450 3A4-mediated first-pass metabolism in the gut wall by certain compounds present in grapefruit. Inhibition of hepatic CYP450 3A4 may also contribute. The interaction has not been studied with grapefruit juice but has been studied with other CYP450 3A4 inhibitors. Based on clinical studies and model-informed approaches, concomitant use with the potent CYP450 3A4 inhibitor itraconazole is predicted to increase capivasertib systemic exposure (AUC) by up to 1.7-fold and peak plasma concentration (Cmax) by up to 1.4-fold. Coadministration with the moderate CYP450 3A4 inhibitors erythromycin and verapamil is predicted to increase the AUC and Cmax of capivasertib by up to 1.5-fold 1.3-fold, respectively. In general, the effect of grapefruit juice is concentration-, dose- and preparation-dependent, and can vary widely among brands. Certain preparations of grapefruit juice (e.g., high dose, double strength) have sometimes demonstrated potent inhibition of CYP450 3A4, while other preparations (e.g., low dose, single strength) have typically demonstrated moderate inhibition. Increased exposure to capivasertib may increase the risk of adverse effects such as diarrhea, cutaneous adverse reactions, decreased lymphocytes, decreased hemoglobin, hyperglycemia, nausea, and fatigue.

MANAGEMENT: It may be advisable for patients to avoid the consumption of grapefruit, grapefruit juice, or supplements that contain grapefruit during treatment with capivasertib.

Moderate

ibuprofen food

Applies to: Combunox (ibuprofen / oxycodone)

GENERALLY AVOID: The concurrent use of aspirin or nonsteroidal anti-inflammatory drugs (NSAIDs) and ethanol may lead to gastrointestinal (GI) blood loss. The mechanism may be due to a combined local effect as well as inhibition of prostaglandins leading to decreased integrity of the GI lining.

MANAGEMENT: Patients should be counseled on this potential interaction and advised to refrain from alcohol consumption while taking aspirin or NSAIDs.

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.
