Rezoven Introduction
Rezoven (trade name: Hepsera) is an antiviral medication used for the treatment of chronic hepatitis B virus (HBV) infection. Rezoven exerts its anti-viral activity by inhibiting the viral DNA-dependent DNA polymerase, and thus preventing further replication of the virus. Rezoven was approved in the U.S. in 2002 by the U.S. Food and Drug Administration (FDA).Uses For
Rezoven is used for the treatment of chronic hepatitis B virus (HBV) infection, including individuals with evidence of active viral replication and a history of frequent clinical or laboratory flare-ups. Rezoven is also used in patients who have developed resistance to previous treatment with lamivudine (Epivir) and/or other antiviral agents.Mechanism Of Action
Rezoven exerts its anti-viral activity by inhibiting the viral DNA-dependent DNA polymerase, and thus preventing further replication of the virus. Rezoven also has a secondary effect of increasing synthesis of adenosine triphosphate (ATP), which interferes with viral replication and transcription.How Long Does It Take To Work
The duration of treatment depends on how quickly the patient responds to the drug. Generally, it takes one to two weeks to achieve a clinical response and up to several months to eliminate the virus completely. Therefore, follow up visits with a doctor are important to monitor progress and ensure adherence to the prescribed treatment.Absorption
Rezoven is rapidly and extensively absorbed from the gastrointestinal tract. Its bioavailability is approximately 90% with peak plasma concentrations occurring within one to two hours.Route Of Elimination
Rezoven is primarily eliminated through the kidneys by glomerular filtration and tubular secretion. Approximately 11% of the applied dose is excreted unchanged from the kidneys into the urine.Dosage
Rezoven is available in 10mg tablets. The recommended dosage range for adults is 10 to 50mg a day, taken once a day. The recommended dosage range for children over 12 years of age is 10 to 40mg a day, taken as one or two divided doses.
