The Tenofovir disoproxil fumarate has a brand name VIREAD. It is obtained from a fumaric acid salt of bis-isopropoxycarbonyloxymethyl ester derivative of tenofovir. Tenofovir disoproxil fumarate is converted to tenofovir, which is an acyclic nucleoside phosphonate (nucleotide) analog of adenosine 5'-monophosphate. Tenofovir exhibits activity against HIV-1 reverse transcriptase. VIREAD are taken orally . The most common aderse reactions include: light to moderate gastrointestinal upset (diarrhea, nausea, vomiting, and flatulence), Metabolic system of low incidence (1%) disease phosphatase, serum phosphate light to moderate decrease. It can also show dangerous lactic acidosis.

【Disposal Methods】
SRP: The most favorable course of action is to use an alternative chemical product with less inherent propensity for occupational exposure or environmental contamination. Recycle any unused portion of the material for its approved use or return it to the manufacturer or supplier. Ultimate disposal of the chemical must consider: the material's impact on air quality; potential migration in soil or water; effects on animal, aquatic, and plant life; and conformance with environmental and public health regulations.

Biomedical Effects and Toxicity

【Pharmacological Action】
- 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.
- Inhibitors of reverse transcriptase (RNA-DIRECTED DNA POLYMERASE), an enzyme that synthesizes DNA on an RNA template.
【Therapeutic Uses】
Tenofovir is indicated, in combination with other antiretroviral agents, for treatment of HIV-1 infection. /Included in US product labeling/
Chronic viral hepatitis has emerged as one of the leading causes of morbidity and mortality among HIV-positive patients. These individuals are at risk for aggressive chronic active hepatitis, cirrhosis, and hepatocellular carcinoma, and eventually, death. Currently available therapies for hepatitis B are limited and include interferon-alpha, lamivudine (3TC), and adefovir. Tenofovir (TDF), a recently approved drug for the treatment of HIV, is also active against hepatitis B. the case of a HIV-positive patient with liver cirrhosis secondary to chronic hepatitis B virus (HBV) with evidence of resistance to 3TC /was reported/. The patient was initially accepted as a liver transplant candidate. However, when TDF was added to his treatment, a remarkable virologic and histopathologic improvement was achieved. The patient was subsequently removed from the liver transplant program and has not suffered from any further hepatic complications. [Ristig M et al; AIDS Patient Care STDS 17 (9): 439-42 (2003)]
【Biomedical Effects and Toxicity】
Tenofovir is eliminated by a combination of glomerular filtration and active tubular secretion. There may be competition for elimination with other compounds that are also renally eliminated.
Following intravenous administration, approximately 70-80% of tenofovir is eliminated unchanged in the urine within 72 hours; following multiple oral doses of tenofovir 300 mg once a day (under fed conditions), 32 +/- 10% of the administered dose is recovered in urine over 24 hours.
Volume of distribution at steady state: 1.3 +/- 0.6 l/kg and 1.2 +/- 0.4 l/kg, following intravenous administration of tenofovir at doses of 1 and 3 mg/kg body weight, respectively.
Oral bioavailability of tenofovir in fasted patients is approximately 25%. Following a single oral dose of 300 mg, the area under the plasma concentration-time curve (AUC) is 2287 +/- 685 ng*hours per ml. NOTE: Administration of food (high in fat meal containing 40-50% fat) increases the oral bioavailability, with an increase in the AUC of approximately 40%.
Plasma tenofovir concentrations and area under the plasma concentration-time curve (AUC) are increased when the drug is administered with a high-fat meal, and administration with a meal is recommended to enhance bioavailability of the drug.
It is unknown whether tenofovir is distributed into human breast milk. However, it is distributed into the milk in lactating rats.
