aspirin tofacitinib

Applies to: aspirin / caffeine / dihydrocodeine and tofacitinib

MONITOR: Coadministration of Janus kinase (JAK) inhibitors with corticosteroids, nonsteroidal anti-inflammatory drugs (NSAIDs), and/or opioids may increase the risk of gastrointestinal (GI) perforation. Patients with a prior history of peptic ulceration or diverticular disease may also have an increased risk. Adverse events of diverticulitis and GI perforation have been infrequently reported in clinical studies and postmarketing use of JAK inhibitors such as baricitinib, ruxolitinib, tofacitinib, and upadacitinib. However, the role of JAK inhibition in these events has not been determined. In studies with rheumatoid arthritis and ulcerative colitis patients, many were receiving background therapy with NSAIDs or corticosteroids.

MANAGEMENT: Caution is recommended when using JAK inhibitors in patients with a history of peptic ulceration or diverticular disease and in patients receiving concomitant treatment with drugs associated with an increased risk of GI perforation such as corticosteroids, NSAIDs, and opioids. Patients should be advised to contact their healthcare provider if they experience signs and symptoms of GI perforation such as severe abdominal pain, fever, chills, nausea, or vomiting.

aspirin caffeine

Applies to: aspirin / caffeine / dihydrocodeine and aspirin / caffeine / dihydrocodeine

One study has reported that coadministration of caffeine and aspirin lead to a 25% increase in the rate of appearance and 17% increase in maximum concentration of salicylate in the plasma. A significantly higher area under the plasma concentration time curve of salicylate was also reported when both drugs were administered together. The exact mechanism of this interaction has not been specified. Physicians and patients should be aware that coadministration of aspirin and caffeine may lead to higher salicylate levels faster.

Drug and food interactions

Moderate

tofacitinib food

Applies to: tofacitinib

MONITOR: Grapefruit juice may increase the plasma concentrations of tofacitinib. The proposed mechanism is inhibition of CYP450 3A4-mediated first-pass metabolism in the gut wall by certain compounds present in grapefruits. The extent and clinical significance are unknown. Moreover, pharmacokinetic alterations associated with interactions involving grapefruit juice are often subject to a high degree of interpatient variability.

MANAGEMENT: Until more information is available, some authorities recommend avoiding consumption of grapefruit juice during tofacitinib therapy (Canada). Patients receiving tofacitinib therapy who ingest grapefruits or grapefruit juice should be monitored for adverse effects and undue fluctuations in plasma drug levels.

Moderate

aspirin food

Applies to: aspirin / caffeine / dihydrocodeine

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.

caffeine food

Applies to: aspirin / caffeine / dihydrocodeine

The effect of grapefruit juice on the pharmacologic activity of caffeine is controversial. One report suggests that grapefruit juice increases the effect of caffeine. The proposed mechanism is inhibition of cytochrome P-450 metabolism of caffeine. However, a well-conducted pharmacokinetic/pharmacodynamic study did not demonstrate this effect. The clinical significance of this potential interaction is unknown.

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.
