Pharmacology of Viraday

PHARMACODYNAMIC MECHANISM OF ACTION: An acyclic nucleoside phosphonate di ester associate of adenosine monophosphate is Tenofovir Disoproxil Fumarate (Viraday), that hydrolysed to Tenofovir, finally cellular enzymes phosphorylated to form Tenofovir diphosphate, an restrict chain terminator. Tenofovir involves with DNA synthesis of HIV through aggressive inhibition of reverse transcriptase and fusion into viral DNA. Tenofovir also prevents hepatitis B virus polymerase, resulting in blockage of viral replication. Emtricitabine (Viraday) is a synthetic nucleoside coordinate of cytidine, which go through phosphorylation occurring inside a cell to emtricitabine 5'-triphosphate, then take part with deoxycytidine 5'-triphosphate and is incorporated into viral DNA which leads to chain termination. Emtricitabine activity against HIV-1, HIV-2 viruses and hepatitis B virus (HBV) while Efavirenz (viraday) is an non nucleoside reverse transcriptase inhibitor that fight against HIV-1 and stops HIV-1 replication and RNA & DNA dependent polymerase activities. PHARMACOKINETIC ABSORPTION: Tenofovir (Viraday) absorbed immediately from the GI tract, bioavailability with high fat meal is approx 25% and duration of peak plasma concentration (PPC) is 1-2hr. In Emtricitabine (Viraday) , bioavailability is 93%(capsulel) and solution 75%, PPC is 1-2 hrs. finally Efavirenz (Viraday) , bioavailabilty is 42% and PPC is 3-5hr. DISTRIBUTION: Tenofovir(Viraday) volume of distribution is 1.2-1.3 L/kg and plasma protein binding is <1%, In Emtricitabine (Trustiva) independent of concentration and protein binding is <4%. Efavirenz (Viraday) is distributed in CSF, enter into breast milk and protein bound is 99% METABOLISM: Tenofovir Disoproxil Fumarate (Viraday), that hydrolysed to Tenofovir, finally cellular enzymes phosphorylated to form Tenofovir diphosphate, an restrict chain terminator. In Emtricitabine (Viraday) is limited metabolism. while in Efavirenz (Viraday) mainly metabolized inCYP3A4 and CYP2B and isoenzyme to inactive hydroxyl metabolite. ELIMINATION: Tenofovir (Viraday) excreted through urine by active glomerular filtration and tubular secretion and half life is 18hr. Emtricitabine (Viraday eliminated highly unchanged in urine and low limit in faeces, half life is 10hr. In Efavirenz (Viraday) excreted via urine(14-34%) and faeces is 16-61% while terminal half life is 52-76hr(single dose) and 40-55hr (multiple dose).
