methylPREDNISolone ISOtretinoin

Applies to: Adlone-80 (methylprednisolone) and Myorisan (isotretinoin)

MONITOR: Theoretical concerns exist that isotretinoin and corticosteroids may have additive effects on bone loss. Decreased bone mineral density (osteomalacia, osteopenia, osteoporosis) and bone fractures have been reported with either treatment alone during prolonged administration. Avascular necrosis has also been reported with corticosteroids, particularly when given in high dosages or for prolonged periods. However, no formal clinical trials have been conducted to evaluate whether there is an interactive effect on bone loss during coadministration.

MANAGEMENT: Caution is advised when isotretinoin is used in combination with corticosteroids, particularly in patients with a history of osteomalacia, osteoporosis, or other disorders of bone metabolism. Bone-related laboratory and radiological tests should be considered.

Drug and food interactions

Moderate

methylPREDNISolone food

Applies to: Adlone-80 (methylprednisolone)

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.
