Both drugs acts like inside cell Lamivudine (Duovir) and Zidovudine (Duovir) is phosphorylated to its active 5-triphosphate metabolite and forms Zidovudine (Duovir) triphosphate and Lamivudine (Duovir) triphosphate (L-TP). The basic action of L-TP and ZDV-TP is inhibition of reverse transcriptase (RT) via DNA chain termination after incorporation of the nucleoside correlated.Both L-TP and ZDV-TP is a weak inhibitor of mammalian DNA polymerases a and b, and mitochondrial DNA polymerase g which has been reported to be incorporated into DNA of cells in culture. PHARMACOKINETIC Absorption: Fastly absorbed from the GI tract. Absorption with food is delayed Bioavailability: 80-87% (lamivudine); approx 60-70% (zidovudine). Time to peak plasma concentration: Approx 1 hr. Distribution: Passes through blood-brain barrier and placenta that enters breast milk and Detected in semen (zidovudine). Volume of distribution: 1.3 L/kg (lamivudine); 1-2.2 L/kg (zidovudine). Plasma protein binding: Up to 36% (lamivudine); 34-38% (zidovudine). Metabolism: Both regimens are metabolized inside the cells to form the active triphosphate . Zidovudine go through hepatic metabolism, mainly to the inactive glucuronide. Excretion: Lamiudine and zidovudine excreted Via urine, (mainly as unchanged drug) Elimination half-life: 5-7 hr (lamivudine); 0.5-3 hr (zidovudine).

Drug Interaction of Duovir

Duovir given with Emtricitabine may develop cross –resistance. Continue use of zidovudine with Ribavirin leads to Excerabtion of anemia. Lamivudine and zalcitabine may prevent intracellularily phosphorylation of one another. Interaction of zidovudine with stavudine and doxorubicin will produce antagonistic effects. Duovir used with interferon alfa in HIV may develop risk of hepatic decompenstion.

Precaution of Duovir

Obese women with hepatomegaly, hepatitis or other risk factors causes liver disease and hepatic steatosis; hepatitis B or C virus co-infection leads risk factors for pancreatitis Patient with poor bone marrow reserve before the treatment. Renal and severe hepatic impairment. Childern Pregnancy. Monitoring Parameters :Monitor haematological parameters observe for appearance of hardened infections and signs and symptoms of pancreatitis. Periodically check liver function test and for several month following discontinuation of therapy for patients co-infected with hepatitis B virus and HIV.
