Tenofovir

Identification

Summary

Tenofovir is a nucleotide analog indicated in the treatment of HIV infections.

Generic Name
Tenofovir
DrugBank Accession Number
DB14126
Background

Tenofovir is an acyclic nucleotide diester analog of adenosine monophosphate.4 In the most strict sense and due to the fact that it presents a phosphate group bound to the nitrogenous base, it is determined as an actual nucleotide analog.4 The antiviral activities of tenofovir were first reported in 1993 and this agent was commercially available since 2008 in the form of tenofovir disoproxil and tenofovir alafenamide in order to obtain oral bioavailability.3,6

Pharmacology

Indication

Tenofovir has been shown to be effective against HIV, herpes simplex virus-2, and hepatitis B virus.5

Pharmacodynamics

Tenofovir has been shown to be highly effective in patients that have never had an antiretroviral therapy and it seemed to have lower toxicity than other antivirals such as stavudine. In phase 3 clinical trials, tenofovir presented a similar efficacy than efavirenz in treatment-naive HIV patients.5 In hepatitis B infected patients, after one year of tenofovir treatment, the viral DNA levels were undetectable.6

Mechanism of action

Once tenofovir is activated by a bi-phosphorylation it acts as an antiviral acyclic nucleoside phosphonate. It is a potent inhibitor of the viral reverse transcriptase with an inhibitory constant of approximately 0.022 micromolar.3

Once activated, tenofovir acts with different mechanisms including the inhibition of viral polymerase causing chain termination and the inhibition of viral synthesis.12 All these activities are attained by its competition with deoxyadenosine 5'-triphosphate in the generation of new viral DNA. Once tenofovir is incorporated in the chain, it induces a chain termination which in order inhibits viral replication.5 The safety of tenofovir relies on its low affinity towards the cellular DNA polymerase including the mitochondrial DNA polymerase gamma.11

Absorption

Tenofovir as the active moiety presents a very low bioavailability when orally administered. Hence, the administration of this active agent is required to be under its two prodrug forms, tenofovir disoproxil and tenofovir alafenamide. This reduced absorption is suggested to be related to the presence of two negative charges among its structure. This negative charge limits its cellular penetration, and its passive diffusion across cellular membranes and intestinal mucosa hindering its availability for oral administration.1

Intravenous tenofovir has been shown to produce a maximum plasma concentration of 2500 ng/ml with an AUC of 4800 ng.h/ml.3

Volume of distribution

Accumulation of tenofovir in plasma is related to the presence of nephrotoxic effects.1 It is reported that tenofovir presents a volume of distribution of 0.813 L/kg.7

Protein binding

Tenofovir is minimally bound to plasma proteins and only about 7.2% of the administered dose is found in the bound state.7

Metabolism

Tenofovir activation is performed by a bi-phosphorylation which in order forms the biologically active compound, tenofovir biphosphate.1 This metabolic activation has been shown to be performed in hepG2 cells and human hepatocytes.8

Route of elimination

Tenofovir is eliminated in the urine by tubular secretion and glomerular filtration. The elimination of this compound is driven by the activity of the human organic anion transporters 1 and 3 and its secretion is mainly ruled by the activity of the multidrug resistance-associated protein 4.1

Half-life

The reported half-life of tenofovir is of 32 hours.2

Clearance

The clearance of tenofovir is highly dependent on the patient renal stage and hence the clearance rate in patients with renal impairment is reported to be of 134 ml/min while in patients with normal function the clearance rate can be of 210 ml/min.9

Toxicity

There haven't been reports regarding the LD50 of the parent compound nor the effects of an overdose. However, based on the reports with the derivative that most rapidly transforms into tenofovir, tenofovir disoproxil, it is recommended to monitor overdose patients. As well, it is widely known that tenofovir is efficiently removed by hemodialysis.10

Administration of high doses of tenofovir has been reported to produce bone toxicity reported as osteomalacia and reduced bone mineral density and to produce some degree of renal toxicity.14
