Interactions between your drugs

Moderate

stiripentol apixaban

Applies to: stiripentol and Eliquis (apixaban)

MONITOR: Coadministration with inhibitors of CYP450 3A4 and/or P-glycoprotein (P-gp) may increase the plasma concentrations of apixaban, which is a substrate of both the isoenzyme and efflux transporter. When apixaban was coadministered with the moderate CYP450 3A4 and P-gp inhibitor diltiazem (360 mg once a day), mean apixaban peak plasma concentration (Cmax) and systemic exposure (AUC) increased by 1.3- and 1.4-fold, respectively. Likewise, coadministration with the P-gp inhibitor naproxen (500 mg single dose) increased the mean apixaban Cmax and AUC by approximately 1.6- and 1.5-fold, respectively.

MANAGEMENT: No dosage adjustment for apixaban is required during concomitant therapy with lone inhibitors of CYP450 3A4 or P-gp, or moderate or weak dual inhibitors of both CYP450 3A4 and P-gp. However, caution may be advisable. Closer monitoring of the pharmacologic effects of apixaban may be appropriate whenever a CYP450 3A4 or P-gp inhibitor is added to or withdrawn from therapy. Patients should be routinely evaluated for signs and symptoms suggesting blood loss such as a drop in hemoglobin and/or hematocrit, hypotension, or fetal distress (in pregnant women).

Drug and food interactions

Moderate

stiripentol food

Applies to: stiripentol

GENERALLY AVOID: Taking stiripentol on an empty stomach may reduce its oral bioavailability. Stiripentol degrades rapidly when exposed to gastric acid in an empty stomach.

GENERALLY AVOID: Alcohol may potentiate the depressant effects of stiripentol on the central nervous system. Concomitant use may result in increased sedation and dizziness as well as impairment of psychomotor skills.

GENERALLY AVOID: It is not known whether stiripentol may reduce theophylline and caffeine metabolism, as data on the potential for inhibition of CYP450 1A2 are limited. Consumption of foods and nutritional products such as cola drinks (which contain significant quantities of caffeine) and chocolate (which contains caffeine and trace amounts of theophylline) may be unsafe during treatment with stiripentol, particularly in children.

MANAGEMENT: Stiripentol should be taken during a meal for optimal absorption; however, it should not be taken with milk, dairy products (e.g., yogurt, soft cream cheese), fruit juice, or carbonated beverages. Patients should be advised to avoid or limit consumption of alcohol and to avoid activities requiring mental alertness such as driving or operating hazardous machinery until they know how the medication affects them. Food and beverages that may contain caffeine or theophylline such as colas, chocolate, coffee, tea, or energy drinks should also be avoided during treatment with stiripentol.

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.
