개요

Lamivudine is a new generation orally active nucleoside analog launched in the U.S.A. for use in combination with zidovudine (AZT) as a first-line therapy for patients with HIV infection. Lamivudine is rapidly converted to phosphorylated metabolites in the body which act as inhibitors and chain terminators of HIV reverse transcriptase (RT), the enzyme required for the replication of the HIV genome. Lamivudine has similar inhibitory potency to RT as AZT but is 10 times less toxic and is active against AZT-resistant strains of HIV. Combination therapy of lamivudine and AZT produced a large decrease in blood-borne virus with an increase in CD4 cells, an effect that can be sustained for 2 years. Since hepatitis B virus (HBV) also encodes a polymerase with a RT function necessary for the conversion of a RNA replicative intermediate to DNA, clinical efficacy has been reported for lamivudine in treating patients with HBV infection. It was reported that the enantiomer of lamivudine is equipotent against HIV but with considerably higher cytotoxicity.

용도

A reverse transcriptase inhibitor. Antiviral.

정의

ChEBI: A monothioacetal that consists of cytosine having a (2R,5S)-2-(hydroxymethyl)-1,3-oxathiolan-5-yl moiety attached at position 1. An inhibitor of HIV-1 reverse transcriptase.

Indications

Lamivudine is a synthetic cytidine analogue used in the treatment of HIV and HBV. Its activation requires phosphorylation by cellular enzymes. Lamivudine triphosphate competitively inhibits HBV DNA polymerase and HIV reverse transcriptase and causes chain termination. It inhibits the activity of mammalian DNA polymerases with a much lower potency.
HIV-1 frequently acquires mutations in reverse transcriptase that result in resistance to lamivudine within 12 weeks of treatment. Mutations in the DNA polymerase of HBV are associated with decreased lamivudine efficacy and have been documented in patients treated with this agent for 6 months or more.

상표명

Epivir (GlaxoSmithKline).

원료

A single codon change at position 184 in the HIV reverse transcriptase gene confers high-level resistance. The K65R mutation is also associated with resistance. In-vitro data indicate that lamivudine resistance may restore HIV sensitivity to zidovudine- and tenofovir-resistant virus.

일반 설명

Lamivudine is (-)-2',3'-dideoxy-3'-thiacytidine, (-)-β-L-(2R,5S)-1,3-oxathiolanylcytosine, 3TC, or (-)-(S)-ddC.Lamivudine is a synthetic nucleoside analog that differsfrom 2β,3β-dideoxycytidine (ddC) by the substitution of asulfur atom in place of a methylene group at the 3'-positionof the ribose ring. In early clinical trials, lamivudine exhibitedhighly promising antiretroviral activity against HIVand low toxicity in the dosages studied.Preliminarypharmacokinetic studies indicated that it exhibited goodoral bioavailability (F=~80%) and a plasma half-life of 2to 4 hours.

Pharmaceutical Applications

An analog of cytidine available for oral administration.

Pharmaceutical Applications

An antiretroviral agent that also exhibits activity against hepatitis B virus and duck hepatitis B virus. Its properties are described in Ch. 36 . Use is limited by the development of resistance within 1 year in up to 25% of treated patients. It is likely to be used with other drugs in the future.

Pharmacokinetics

Oral absorption: 80–85%
Cmax, 300 mg once daily: 2.0 mg/L
Plasma half-life: 5–7 h
Volume of distribution: 1.3 L/kg
Plasma protein binding: <36%
Absorption
It is rapidly absorbed and there is no significant difference in bioavailability when taken with food.
Distribution
It penetrates moderately well into the CNS. The semen:plasma ratio is about 9.1 (2.3–16.1). It is secreted into breast milk.
Metabolism and excretion
Less than 10% of the administered dose undergoes hepatic metabolism. Over 70% of the dose is subject to renal clearance via active tubular secretion. Dosage adjustments are not routinely recommended in the presence of renal or hepatic impairment.

Clinical Use

Therapy of chronic hepatitis B

Clinical Use

Lamivudine is indicated for the treatment of HIV when used in combination with other antiretroviral agents.A lower dose than that used to treat HIV is approved for the treatment of HBV. Although lamivudine initially improves histological and biochemical measures of hepatic function and reduces HBV DNA to below the limits of detection, withdrawal of the drug usually results in disease recurrence. Resistance appears in up to onethird of patients after 1 year of treatment.

부작용

Lamivudine is relatively safe and non-toxic. Animal studies of very high doses did not result in any organ toxicity. In patients co-infected with HIV and HBV, cessation of lamivudine therapy may result in clinical and/or laboratory evidence of recurrent hepatic disease that may be more severe in patients with hepatic decompensation. Tests of liver function and inflammation and markers of HBV replication should be periodically monitored.
Lamivudine competes with emtricitabine for the enzymes involved in intracellular phosphorylation and co-administration is contraindicated.

부작용

The most common adverse effects of lamivudine seen at doses used to treat HBV are mild; they include headache, malaise, fatigue, fever, insomnia, diarrhea, and upper respiratory infections. Elevated alanine aminotransferase (ALT), serum lipase, and creatine kinase may also occur. The safety and efficacy of lamivudine in patients with decompensated liver disease have not been established. Dosage adjustment is required in individuals with renal impairment. Coadministration of trimethoprim–sulfamethoxazole decreases the renal clearance of lamivudine.
