Adverse Reactions
Neutropenia, leukopenia; decreased appetite; neuropathy, dizziness, dysgeusia; vision disorder; bradycardia; vomiting, diarrhoea, nausea, constipation; elevated transaminases; rash; oedema, fatigue. Prolonged ECG QT, syncope; interstitial lung disease; oesophagitis, dyspepsia; increased blood alkaline phosphatase; renal cyst, increased blood creatinine; decreased blood testosterone.
Drug Interactions
Increased plasma conc w/ strong CYP3A inhibitors (eg, atazanavir, indinavir, nelfinavir, ritonavir, saquinavir), azole antifungals (eg, itraconazole, ketoconazole, voriconazole), macrolides (eg, clarithromycin, telithromycin, troleandomycin), grapefruit or grapefruit juice. Increased systemic exposure w/ ketoconazole. May alter plasma conc of CYP3A substrates w/ narrow therapeutic indices eg, alfentanil, cisapride, cyclosporine, ergot derivatives, fentanyl, pimozide, quinidine, sirolimus, tacrolimus. Decreased AUCinf & Cmax w/ rifampicin. Decreased plasma conc w/ strong CYP3A inducers eg, carbamazepine, phenobarb, phenytoin, rifabutin, rifampin, St. John's wort. Concomitant use w/ drugs predominantly metabolized by pregnane X receptor-regulated enzymes eg, CYP2B6, CYP2C8, CYP2C9, UGT1A1 (except CYP3A4); substrates of UGTs eg, paracetamol, morphine, irinotecan. Effectiveness of OCs may be altered. May increase therapeutic effect & AR of P-gp substrates eg, digoxin, dabigatran, colchicine, pravastatin. Decreased solubility & subsequently reduced bioavailability w/ drugs that elevate gastric pH eg, PPIs, H2 blockers, antacids.
