methylPREDNISolone tofacitinib

Applies to: Depopred (methylprednisolone) and tofacitinib

MONITOR CLOSELY: Coadministration of baricitinib or tofacitinib with other immuno- or myelosuppressive agents may potentiate the risk of infections as well as lymphoma and other malignancies. Serious and sometimes fatal infections due to bacterial, mycobacterial, invasive fungal, viral, or other opportunistic pathogens have been reported in patients receiving baricitinib and tofacitinib, most of whom were taking concomitant immunosuppressants such as methotrexate or corticosteroids. Lymphoma and other malignancies have also been observed with tofacitinib use, with or without concomitant immunosuppressants. Epstein Barr virus-associated posttransplant lymphoproliferative disorder has been observed at an increased rate in renal transplant patients treated with tofacitinib and concomitant immunosuppressive agents (basiliximab, high-dose corticosteroids, and mycophenolic acid) relative to cyclosporine plus the same induction regimen (2.3% vs. 0%). The most common serious infections reported with baricitinib treatment include pneumonia, herpes zoster, and urinary tract infection. Opportunistic infections include tuberculosis, multidermatomal herpes zoster, esophageal candidiasis, pneumocystosis, acute histoplasmosis, cryptococcosis, cytomegalovirus, and BK virus. Lymphoma and other malignancies have also been observed with baricitinib use, with or without concomitant immunosuppressants.

MANAGEMENT: Close monitoring for the development of infection is recommended if baricitinib or tofacitinib is used in combination with other immuno- or myelosuppressive agents, including the possible development of tuberculosis in patients who tested negative for latent tuberculosis infection prior to initiating therapy. Lymphocyte and neutrophil counts as well as hemoglobin should be evaluated at baseline and regularly during therapy, and the baricitinib or tofacitinib dosage adjusted as necessary in accordance with the product labeling. Patients should be advised to contact their physician if they develop signs and symptoms of infection such as fever, chills, diarrhea, sore throat, muscle aches, shortness of breath, blood in phlegm, weight loss, red or inflamed skin, body sores, and pain or burning during urination. If a serious infection, an opportunistic infection, or sepsis develops, baricitinib should be interrupted until the infection is controlled.

MONITOR Baricitinib and tofacitinib, both Janus kinase (JAK) inhibitors, have been associated with an increased risk of diverticulitis (DV) and gastrointestinal (GI) perforation, particularly in patients with risk factors (e.g., history of diverticulosis or diverticulitis, concomitant use of other agents associated with DV). Cases of DV and GI perforation have been reported in patients receiving baricitinib concomitantly with other agents linked to an increased risk of DV, such as aspirin, non-steroidal anti-inflammatory drugs (NSAIDs), corticosteroids, and opioids. The mechanism of this interaction and the role of JAK inhibition, if any, has not been determined.

MANAGEMENT: Caution is recommended when using baricitinib or tofacitinib in patients with a history of diverticular disease and in patients receiving long-term concomitant treatment with drugs associated with an increased risk of DV and/or GI perforation, such as aspirin, NSAIDs, corticosteroids, and opioids. Patients should be advised to contact their healthcare provider if they experience signs of DV or GI perforation, such as severe abdominal pain, fever, nausea, or vomiting.

Drug and food interactions

Moderate

methylPREDNISolone food

Applies to: Depopred (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.
