🔬 How This Medicine Works (Pharmacology)

Pharmacokinetics

AbsorptionEmtricitabine is rapidly and extensively absorbed after oral administration, with peak plasma concentrations reached within about 1 to 2 hours. Tenofovir disoproxil fumarate is a prodrug that is rapidly converted to tenofovir, and peak tenofovir concentrations occur within about 1 to 2 hours. Food does not significantly affect the absorption of either component.

DistributionBoth emtricitabine and tenofovir distribute into body tissues, including intracellular compartments where they are activated. Tenofovir binds minimally to plasma proteins, while emtricitabine binding is very low. Both are eliminated primarily by the kidneys.

Protein BindingEmtricitabine is less than 4% bound to plasma proteins. Tenofovir is less than 1% bound to plasma proteins. These low binding values mean that protein-binding interactions with other medicines are unlikely.

MetabolismEmtricitabine undergoes limited metabolism, with a small amount converted to inactive metabolites. Tenofovir disoproxil fumarate is rapidly converted to tenofovir by esterases, and tenofovir itself is not significantly metabolized. Neither component strongly affects liver enzymes.

Half-LifeThe elimination half-life of emtricitabine is approximately 10 hours. The elimination half-life of tenofovir is approximately 17 hours. These values may be prolonged in people with reduced kidney function.

ExcretionEmtricitabine is excreted primarily unchanged in the urine by glomerular filtration and active tubular secretion. Tenofovir is also excreted unchanged in the urine by glomerular filtration and active tubular secretion. Kidney function significantly affects the removal of both medicines.

BioavailabilityThe oral bioavailability of emtricitabine is approximately 93%. The oral bioavailability of tenofovir from tenofovir disoproxil fumarate is approximately 25% under fasting conditions. Food does not meaningfully change the bioavailability of either component.

Onset of ActionAntiviral effects begin within days of starting therapy, but a measurable reduction in viral load is usually seen within 2 to 4 weeks. Full suppression of the virus may take several months of consistent treatment.

Peak Plasma TimePeak plasma concentrations of emtricitabine occur about 1 to 2 hours after oral administration. Peak plasma concentrations of tenofovir occur about 1 to 2 hours after oral administration.

Duration of ActionThe antiviral effect lasts as long as the medicine is taken regularly. Because the half-lives allow once-daily dosing, the effect is maintained over a 24-hour period when taken as prescribed.

How It Works

This medicine combines two antiretroviral agents that work by interfering with the reverse transcriptase enzyme, which human immunodeficiency virus uses to convert its ribonucleic acid into deoxyribonucleic acid. Emtricitabine is a nucleoside analogue that is phosphorylated inside cells to its active triphosphate form, which competes with natural nucleotides and causes chain termination when incorporated into viral deoxyribonucleic acid. 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 help control the infection. This medicine does not cure human immunodeficiency virus infection.

Mechanism Steps

1

Cellular uptake and activation: Emtricitabine and tenofovir disoproxil fumarate enter cells and are converted by cellular enzymes into their active triphosphate forms.

2

Competition with natural nucleotides: The active forms compete with natural deoxynucleotides for incorporation into viral deoxyribonucleic acid by reverse transcriptase.

3

Deoxyribonucleic acid chain termination: Once incorporated, these agents lack the chemical group needed to continue the deoxyribonucleic acid chain, so viral deoxyribonucleic acid synthesis stops.

4

Reduced viral replication: Because the virus cannot complete its deoxyribonucleic acid, it cannot replicate efficiently, which lowers the viral load in the body.
