MONITOR: Coadministration with inhibitors of CYP450 3A4 may increase the systemic bioavailability of budesonide, which undergoes extensive first-pass and systemic metabolism via intestinal and hepatic CYP450 3A4. In pharmacokinetic studies, 6- to 8-fold increases in budesonide systemic exposure (AUC) have been observed during coadministration of the potent CYP450 3A4 inhibitor ketoconazole with different oral formulations of budesonide. When ketoconazole was administered 12 hours after budesonide in one study, the AUC increase was approximately half that reported during simultaneous administration. In a prospective study of a cystic fibrosis center patient population, 11 of 25 patients receiving high-dose itraconazole (400 to 600 mg/day) and budesonide oral inhalation therapy (800 to 1600 mcg/day) were found to have adrenal insufficiency, including one who developed Cushing's syndrome, compared to none in a group of 12 patients treated with itraconazole alone. There was also no adrenal insufficiency in a group of 30 cystic fibrosis patients retrospectively included as controls, 24 of whom had been treated with high-dose inhaled budesonide for several years. Adrenal function improved, but did not normalize, in 10 of the 11 patients during a follow-up of two to ten months after discontinuation of itraconazole and institution of hydrocortisone replacement therapy. Limited pharmacokinetic data indicate that itraconazole (200 mg once daily) may increase the plasma levels of budesonide by about 4-fold following inhalation of a single 1000 mcg dose, which may be mainly due to increased bioavailability of the swallowed portion of the dose.

MANAGEMENT: The possibility of increased systemic adverse effects of budesonide should be considered during coadministration with CYP450 3A4 inhibitors. If concomitant use cannot be avoided, the dosing times between budesonide and the CYP450 3A4 inhibitor should be separated by as much as possible. In addition, the lowest effective dosage of budesonide should be prescribed, and further adjustments made as necessary according to therapeutic response and tolerance. Patients should be monitored for signs and symptoms of hypercorticism such as acne, striae, thinning of the skin, easy bruising, moon facies, dorsocervical "buffalo" hump, truncal obesity, increased appetite, acute weight gain, edema, hypertension, hirsutism, hyperhidrosis, proximal muscle wasting and weakness, glucose intolerance, exacerbation of preexisting diabetes, depression, and menstrual disorders. Other systemic glucocorticoid effects may include adrenal suppression, immunosuppression, posterior subcapsular cataracts, glaucoma, bone loss, and growth retardation in children and adolescents.

Drug and food interactions

Moderate

budesonide food

Applies to: Uceris (budesonide)

GENERALLY AVOID: Grapefruit juice may increase the plasma concentrations and systemic effects of orally administered budesonide. The proposed mechanism is inhibition of CYP450 3A4-mediated first-pass metabolism in the gut wall by certain compounds present in grapefruits. According to the manufacturer, the systemic exposure of oral budesonide approximately doubles after extensive intake of grapefruit juice.

MANAGEMENT: Patients receiving budesonide should avoid the regular consumption of grapefruits and grapefruit juice to prevent undue increases in plasma budesonide levels and systemic effects.

MONITOR: Grapefruit juice may increase the plasma concentrations of orally administered drugs that are substrates of the CYP450 3A4 isoenzyme. The proposed mechanism is inhibition of CYP450 3A4-mediated first-pass metabolism in the gut wall by certain compounds present in grapefruit. Because grapefruit juice inhibits primarily intestinal rather than hepatic CYP450 3A4, the magnitude of interaction is greatest for those drugs that undergo significant presystemic metabolism by CYP450 3A4 (i.e., drugs with low oral bioavailability). 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. Pharmacokinetic interactions involving grapefruit juice are also subject to a high degree of interpatient variability, thus the extent to which a given patient may be affected is difficult to predict.

MANAGEMENT: Patients who regularly consume grapefruit or grapefruit juice should be monitored for adverse effects and altered plasma concentrations of drugs that undergo significant presystemic metabolism by CYP450 3A4. Grapefruit and grapefruit juice should be avoided if an interaction is suspected. Orange juice is not expected to interact with these drugs.

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.
