Applies to: Sinuva (mometasone nasal) and stiripentol

Consumer information for this interaction is not currently available.

MONITOR: Coadministration with potent inhibitors of CYP450 3A4 may increase the plasma concentrations of mometasone, which is primarily metabolized by the isoenzyme. In healthy subjects coadministered mometasone (400 mcg inhaled twice daily for 9 days) with the potent CYP450 3A4 inhibitor ketoconazole (200 mg orally twice daily on days 4 to 9), 4 out of 12 subjects had peak plasma concentrations of mometasone increase from less than 150 pcg/mL on day 3 before the addition of ketoconazole to more than 200 pcg/mL afterwards. Serum cortisol AUC also decreased slightly after ketoconazole was added. The clinical significance of these findings is unknown.

MANAGEMENT: The possibility of increased systemic adverse effects of mometasone should be considered during coadministration with potent CYP450 3A4 inhibitors. Some authorities advise against concomitant use unless the potential benefit outweighs the risk. If the combination cannot be avoided, the dosing times between mometasone and the CYP450 3A4 inhibitor should be separated by as much as possible. In addition, the lowest effective dosage of mometasone should be prescribed, and further adjustments made as necessary according to therapeutic response and tolerance. Alternatively, a less potent, less lipophilic, and/or shorter-acting agent such as beclomethasone may be considered. Beclomethasone is also less dependent on CYP450 3A4 metabolism. Patients should be monitored for signs and symptoms of hypercorticism such as acne, striae, thinning of the skin, easy bruising, moon facies, dorsocervical "buffalo" hump, truncal obesity, increased appetite, acute weight gain, edema, hypertension, hirsutism, hyperhidrosis, proximal muscle wasting and weakness, glucose intolerance, exacerbation of preexisting diabetes, depression, and menstrual disorders. Other systemic glucocorticoid effects may include adrenal suppression, immunosuppression, posterior subcapsular cataracts, glaucoma, bone loss, and growth retardation in children and adolescents.

Drug and food interactions


stiripentol food

Applies to: stiripentol

Consumer information for this interaction is not currently available.

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.
