Pregnancy. Renal impairment. Hepatomegaly, hepatic steatosis, hepatitis, hepatic impairment or at risk for liver disease. Patients co-infected with hepatitis C and HIV and on αinterferon and ribavirin therapy. Test for presence of chronic HBV before initiating therapy. If emtricitabine is discontinued in patients co-infected with HIV and HBV, monitor hepatic function for several months for acute exacerbation of hepatitis. Discontinue therapy if there is a rapid rise in aminotransferase concentrations, progressive hepatomegaly or steatosis, metabolic or lactic acidosis of unknown cause. Patient to seek medical advice if there is joint aches or stiffness or difficulty in movement. Monitor child exposed in utero to combination drug for possible mitochondrial dysfunction.
Phản ứng phụ
Diarrhoea, nausea, vomiting, dyspepsia, abdominal pain, elevated amylase, lipase, creatine kinase or LFT, anaemia, headache, insomnia, dizziness, abnormal dreams, rash, hyper-pigmentation, asthenia, pain, osteonecrosis, metabolic abnormalities (e.g. hypertriglyceridaemia, hypercholesterolaemia, insulin resistance, hyperglycaemia, hyperlactataemia), hyperbilirubinaemia, lipodystrophy, immune reconstitution syndrome, neutropenia, anaemia.
Potentially Fatal: Lactic acidosis and severe hepatomegaly with steatosis.
Quá liều
Treatment is supportive and monitor for signs of toxicity. Haemodialysis may be useful.
Tương tác
Increased serum concentration of emtricitabine or co-administered drug if taken with drugs that are eliminated by active tubular secretion. Increased risk of peripheral neuropathy with bortezomib.
Potentially Fatal: Do not use emtricitabine with lamivudine due to similar resistance profile. Increased risk if lactic acidosis with α-interferon.
Tác dụng
Description: Emtricitabine, a synthetic nucleoside analogue of cytidine, undergoes phosphorylation intracellularly to emtricitabine 5'-triphosphate. Emtricitabine 5'-triphosphate then competes with deoxycytidine 5'-triphosphate and is incorporated into viral DNA which results in chain termination. It has activity against HIV-1 and HIV-2 viruses as well as hepatitis B virus (HBV).
Pharmacokinetics:
Absorption: Rapidly and well absorbed from GI tract; peak plasma concentrations achieved in 1-2 hours. Bioavailability: 93% (capsules); 75% (oral solution).
Distribution: Protein binding: < 4%, independent of concentration.
Metabolism: Limited metabolism.
Excretion: Excreted largely unchanged in the urine and to a lesser extent in the faeces. Plasma elimination half-life: 10 hr.
Bảo quản
Capsule: Store between 15-30°C (59-86°F). Oral Solution: Store refrigerated, between 2-8°C (36-46°F), use within 3 mth if stored between 15-30 °C (59-86 °F).
