4 Drug and Medication Information
4.1 Drug Indication

Tenofovir has been shown to be effective against HIV, herpes simplex virus-2, and hepatitis B virus. To know more about the specific product indications, please visit the information in the orally available forms of tenofovir, [tenofovir alafenamide] and [tenofovir disoproxil].


Treatment of HIV-1 infection:

- Truvada is indicated in antiretroviral combination therapy for the treatment of HIV-1 infected adults.

- Truvada is also indicated for the treatment of HIV-1 infected adolescents, with NRTI resistance or toxicities precluding the use of first line agents, aged 12 to < 18 years.

Pre-exposure prophylaxis (PrEP):

- Truvada is indicated in combination with safer sex practices for pre-exposure prophylaxis to reduce the risk of sexually acquired HIV-1 infection in adults at high risk.


5 Pharmacology and Biochemistry
5.1 Pharmacology

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. In hepatitis B infected patients, after one year of tenofovir treatment, the viral DNA levels were undetectable.


5.2 MeSH Pharmacological Classification

Antiviral Agents

Agents used in the prophylaxis or therapy of VIRUS DISEASES. Some of the ways they may act include preventing viral replication by inhibiting viral DNA polymerase; binding to specific cell-surface receptors and inhibiting viral penetration or uncoating; inhibiting viral protein synthesis; or blocking late stages of virus assembly. (See all compounds classified as Antiviral Agents.)


Anti-HIV Agents

Agents used to treat AIDS and/or stop the spread of the HIV infection. These do not include drugs used to treat symptoms or opportunistic infections associated with AIDS. (See all compounds classified as Anti-HIV Agents.)


Reverse Transcriptase Inhibitors

Inhibitors of reverse transcriptase (RNA-DIRECTED DNA POLYMERASE), an enzyme that synthesizes DNA on an RNA template. (See all compounds classified as Reverse Transcriptase Inhibitors.)

5.5 Absorption, Distribution and Excretion

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


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.


Volume of Distribution

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


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.


5.6 Metabolism/Metabolites

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


5.7 Biological Half-Life

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


5.8 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. Once activated, tenofovir acts with different mechanisms including the inhibition of viral polymerase causing chain termination and the inhibition of viral synthesis. 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. The safety of tenofovir relies on its low affinity towards the cellular DNA polymerase including the mitochondrial DNA polymerase gamma.
