GENERALLY AVOID: Grapefruit and/or grapefruit juice may increase the plasma concentrations of suzetrigine and M6-SUZ, a major active metabolite whose systemic exposure (AUC) at steady state is approximately 3 times that of the parent drug but exhibits 3.7-fold less potency in blocking the NaV1.8 voltage-gated sodium channels responsible for transmission of pain signals to the spinal cord and brain. The proposed mechanism for the interaction is inhibition of CYP450 3A4-mediated first-pass metabolism in the gut wall by certain compounds present in grapefruit. Inhibition of hepatic CYP450 3A4 may also contribute. The interaction has not been studied with grapefruit juice but has been reported for other CYP450 3A4 inhibitors. When a single dose of suzetrigine was administered with itraconazole, a potent CYP450 3A4 inhibitor, mean suzetrigine peak plasma concentration (Cmax) and systemic exposure (AUC) increased by 1.5- and 4.8-fold, respectively, while mean Cmax of M6-SUZ decreased by 32% and AUC increased by 4.4-fold. Coadministration of fluconazole, a moderate CYP450 3A4 inhibitor, with suzetrigine dosed according to the manufacturer's recommended dosage modification is predicted to increase the mean Cmax and AUC of suzetrigine by 1.4- and 1.5-fold, respectively, while the mean Cmax and AUC of M6-SUZ are predicted to increase by 1.1- and 1.2-fold, respectively, compared to suzetrigine administered at the regular recommended dosage without fluconazole. In general, the effects of grapefruit products are concentration-, dose- and preparation-dependent, and can vary widely among brands. Certain preparations of grapefruit (e.g., high dose, double strength) have sometimes demonstrated potent inhibition of CYP450 3A4, while other preparations (e.g., low dose, single strength) have typically demonstrated moderate inhibition.
ADJUST DOSE INTERVAL: Food may delay the absorption of suzetrigine without impacting the overall systemic exposures to parent drug and M6-SUZ. Administration of suzetrigine 100 mg (the first dose) with a high-fat meal (800 to 1000 calories; 50% from fat), a moderate-fat meal (600 calories; 30% from fat), and a low-fat meal (<=500 calories; <=25% from fat) resulted in decreased initial plasma concentrations of suzetrigine and M6-SUZ compared to administration in a fasted state. The median time to reach peak plasma concentration (Tmax) for suzetrigine and M6-SUZ when administered with either a high-fat or moderate-fat meal was 5 hours and 24 hours, respectively, versus 3 hours and 8 to 10 hours, respectively, when administered in the fasted state. The Cmax and AUC of suzetrigine and M6-SUZ were not affected by any of the meal conditions, including a high-fat meal consumed one hour after suzetrigine. Administration of the second suzetrigine dose of 50 mg with or without regard to meals is also predicted to have no effect on the systemic exposures of suzetrigine and M6-SUZ.
MANAGEMENT: Patients should avoid consumption of foods or drinks containing grapefruit during treatment with suzetrigine. The starting dose of 100 mg should be taken on an empty stomach at least 1 hour before or 2 hours after food, although clear liquids (e.g., water, apple juice, vegetable broth, tea, black coffee) may be consumed during this time. Subsequent doses may be taken with or without food.
cholecalciferol food
Applies to: Vitamin D3 (cholecalciferol)
Treatment with cholecalciferol may require you to adjust your dietary intake of foods which contain natural or added calcium, phosphate (organic and inorganic), and vitamin D. Ingesting too much vitamin D or having elevated calcium and/or phosphorus levels in the blood and urine can lead to toxic effects, such as having an irregular heart rhythm, seizures, kidney stones, and eventual calcification of your blood vessels, cornea and/or the soft tissues in your body. Your doctor will monitor the levels of calcium and phosphorus in your blood during treatment with cholecalciferol. Please speak with your healthcare team to determine if you require a specialized diet, particularly if you have reduced kidney function, and to discuss any other questions or concerns you have. You may require additional monitoring or a dose adjustment of cholecalciferol if your diet changes. Fortified foods will state on their labeling how much calcium, phosphate, and/or vitamin D has been added. The National Institutes of Health, Office of Dietary Supplements also provides information on which foods contain calcium, phosphorus, and vitamin D. You should avoid abrupt changes in your dietary calcium intake and seek medical attention if you experience early symptoms of vitamin D intoxication such as weakness, fatigue, headache, drowsiness, vertigo, ringing in the ears, loss of appetite, nausea, vomiting, constipation, dry mouth, metallic taste, muscle pain, bone pain, muscle incoordination, and low muscle tone. Late symptoms may include frequent urination, excessive thirst, weight loss, conjunctivitis ("pink eye"), light sensitivity, runny nose, itching, increased body temperature, and irregular heart rhythm. It is important to tell your doctor about all other medications you use, including vitamins and herbs. Do not stop using any medications without first talking to your doctor.
