🔬 How This Medicine Works (Pharmacology)

Pharmacokinetics

AbsorptionLamivudine is rapidly absorbed after oral administration, with a bioavailability of approximately 80-85% in adults. Tenofovir disoproxil fumarate is absorbed as tenofovir, with a bioavailability of about 25% when taken with food. Food does not significantly affect the absorption of either drug.
DistributionBoth drugs distribute widely into body tissues. Lamivudine has a volume of distribution of about 1.3 L/kg. Tenofovir has a volume of distribution of about 1.3 L/kg. Both drugs cross the placenta and are excreted in breast milk.
Protein BindingLamivudine is less than 36% bound to plasma proteins. Tenofovir is less than 1% bound to plasma proteins.
MetabolismLamivudine is not significantly metabolized and is excreted largely unchanged in the urine. Tenofovir disoproxil fumarate is rapidly converted to tenofovir, which is not metabolized by the liver and is excreted unchanged by the kidneys.
Half-LifeThe elimination half-life of lamivudine is approximately 5 to 7 hours. The elimination half-life of tenofovir is approximately 17 hours.
ExcretionBoth drugs are primarily excreted unchanged in the urine. Lamivudine is eliminated by renal excretion, and tenofovir is eliminated by a combination of glomerular filtration and active tubular secretion.
BioavailabilityLamivudine bioavailability is approximately 80-85%. Tenofovir bioavailability is approximately 25% when taken with food.
Onset of ActionThe antiviral effect begins within days of starting therapy, but a significant reduction in viral load is usually seen within 2 to 4 weeks. Maximum suppression may take several months.
Peak Plasma TimeLamivudine reaches peak plasma concentrations in about 1 hour. Tenofovir reaches peak plasma concentrations in about 1 to 2 hours.
Duration of ActionThe antiviral effect lasts as long as the drug is present in the body. With once-daily dosing, the effect is maintained throughout the 24-hour dosing interval.

How It Works

This medicine combines two antiretroviral drugs that inhibit the reverse transcriptase enzyme of HIV. Lamivudine is a nucleoside analogue that is phosphorylated inside cells to its active triphosphate form, which competes with natural nucleotides and causes chain termination during viral DNA synthesis. Tenofovir disoproxil fumarate is a prodrug that is converted to tenofovir, a nucleotide analogue that also inhibits reverse transcriptase and acts as a chain terminator. Together they reduce viral replication and lower the viral load.

Mechanism Steps

1
Cellular uptake and phosphorylation: Lamivudine enters cells and is converted by cellular kinases to lamivudine triphosphate, its active form. Tenofovir disoproxil fumarate is hydrolyzed to tenofovir, which is then phosphorylated to tenofovir diphosphate.
2
Competition with natural nucleotides: The active triphosphate forms of both drugs compete with the natural deoxynucleotides for binding to the active site of HIV reverse transcriptase.
3
DNA chain termination: Once incorporated into the growing viral DNA chain, both drugs lack the necessary 3'-hydroxyl group, causing the chain to terminate and preventing further viral DNA synthesis.
4
Reduction of viral replication: The combined effect is a marked reduction in the ability of HIV to replicate, which lowers the viral load and allows the immune system to recover.
