Interactions between your drugs

Moderate

caffeine osilodrostat

Applies to: BC Fast Pain Relief (aspirin / caffeine) and osilodrostat

MONITOR: Coadministration with osilodrostat may increase the plasma concentrations of drugs that are metabolized by CYP450 1A2, 2C19, 2D6, and/or 3A4. Osilodrostat has been shown to be a moderate inhibitor of CYP450 1A2, a mild to borderline moderate inhibitor of CYP450 2C19, and a weak inhibitor of CYP450 2D6 and 3A4. In a pharmacokinetic study with 20 healthy volunteers using a single 50 mg dose of osilodrostat and a probe drug cocktail, osilodrostat increased the exposures to caffeine (CYP450 1A2 substrate), omeprazole (CYP450 2C19 substrate), dextromethorphan (CYP450 2D6 substrate), and midazolam (CYP450 3A4/5 substrate) by 2.5-, 1.9-, 1.5- and 1.5-fold, respectively.

MANAGEMENT: Caution is advised when osilodrostat is used concurrently with drugs that are substrates of CYP450 1A2, 2C19, 2D6 and/or 3A4, particularly those with a narrow therapeutic range. Dosage adjustments as well as clinical and laboratory monitoring may be appropriate for some drugs whenever osilodrostat is added to or withdrawn from therapy.

aspirin caffeine

Applies to: BC Fast Pain Relief (aspirin / caffeine) and BC Fast Pain Relief (aspirin / caffeine)

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

aspirin food

Applies to: BC Fast Pain Relief (aspirin / caffeine)

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

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.
