Interactions between your drugs

Moderate

stiripentol polatuzumab vedotin

Applies to: Diacomit (stiripentol) and polatuzumab vedotin

MONITOR: Coadministration with inhibitors of CYP450 3A4 may increase exposure to unconjugated monomethyl auristatin E (MMAE), the anti-mitotic and cytotoxic component of polatuzumab vedotin. MMAE is a substrate for CYP450 3A4. Concomitant use of polatuzumab vedotin with ketoconazole, a potent CYP450 3A4 inhibitor, is predicted to increase unconjugated MMAE exposure (AUC) by 45% according to the product labeling. No data are available for other, less potent CYP450 3A4 inhibitors.

MANAGEMENT: Caution is advised when polatuzumab vedotin is used concomitantly with CYP450 3A4 inhibitors. Patients should be monitored for development or exacerbation of toxicities such as peripheral neuropathy, myelosuppression, opportunistic infections, tumor lysis syndrome and hepatotoxicity, and the dosing of polatuzumab vedotin adjusted or withheld as necessary in accordance with the product labeling.

Drug and food interactions

Moderate

stiripentol food

Applies to: Diacomit (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.
