Interactions between your drugs
cycloSPORINE ticagrelor
Applies to: cyclosporine and Brilinta (ticagrelor)
MONITOR: Coadministration of cyclosporine and ticagrelor may increase the plasma concentrations of both drugs. Although the interaction has not been studied, competitive or noncompetitive inhibition of P-glycoprotein and CYP450 3A4 is possible, since these drugs are substrates as well as inhibitors of both the drug efflux transporter and isoenzyme. A case report of a 49-year-old man with a stable renal graft managed with cyclosporine (75 mg twice a day) who was initiated on ticagrelor for treatment of unstable angina pectoris showed an increase in previously stable cyclosporine trough concentrations and minor bleeding events 7 days after ticagrelor was started. Systemic cyclosporine exposure (AUC) was estimated to have increased from 1980 mcg*h/L up to 4740 mcg*h/L. Ticagrelor was discontinued and replaced by clopidogrel, and the daily dose of cyclosporine was reduced by 25 mg. Cyclosporine trough concentrations decreased within 13 days after ticagrelor therapy was stopped and the patient subsequently returned to stable cyclosporine trough levels and the original cyclosporine dose of 75 mg twice a day. There were no further reports of bleeding events.
MANAGEMENT: Caution is advised if cyclosporine and ticagrelor are used in combination. Cyclosporine blood levels and renal function should be monitored more closely whenever ticagrelor is added to or withdrawn from therapy, and the cyclosporine dosage adjusted as necessary. Patients should be advised to notify their physician if they experience bleeding complications or signs and symptoms of cyclosporine toxicity such as nausea, vomiting, diarrhea, abdominal pain, dizziness, fatigue, headache, tremors, and convulsions.

Drug and food interactions
cycloSPORINE food
Applies to: cyclosporine
GENERALLY AVOID: Administration with grapefruit juice (compared to water or orange juice) has been shown to increase blood concentrations of cyclosporine with a relatively high degree of interpatient variability. The mechanism is inhibition of CYP450 3A4-mediated first-pass metabolism in the gut wall by certain compounds present in grapefruits.
GENERALLY AVOID: Administration with red wine or purple grape juice may decrease blood concentrations of cyclosporine. In 12 healthy volunteers, 12 ounces total of a merlot consumed 15 minutes prior to and during cyclosporine administration (single 8 mg/kg dose of Sandimmune) decreased cyclosporine peak blood concentration (Cmax) and systemic exposure (AUC) by 38% and 30%, respectively, compared to water. The time to reach peak concentration (Tmax) doubled, and oral clearance increased 50%. Similarly, one study were 12 healthy patients were administered purple grape juice and a single dose of cyclosporine showed a 30% and a 36% decrease in cyclosporine systemic exposure (AUC) and peak blood concentration (Cmax), respectively. The exact mechanism of interaction is unknown but may involve decreased cyclosporine absorption.
MONITOR: Food has been found to have variable effects on the absorption of cyclosporine. There have been reports of impaired, unchanged, and enhanced absorption during administration with meals relative to the fasting state. The mechanisms are unclear. Some investigators found an association with the fat content of food. In one study, increased fat intake resulted in significantly increased cyclosporine bioavailability and clearance. However, the AUC and pharmacodynamics of cyclosporine were not significantly affected, thus clinical relevance of these findings may be minimal.
MANAGEMENT: Patients receiving cyclosporine therapy should be advised to either refrain from or avoid fluctuations in the consumption of grapefruits and grapefruit juice. Until more data are available, the consumption of red wine or purple grape juice should preferably be avoided or limited. All oral formulations of cyclosporine should be administered on a consistent schedule with regard to time of day and relation to meals so as to avoid large fluctuations in plasma drug levels.
