A unique and potentially fatal hypersensitivity reaction occurs in 2% to 5% of patients receiving abacavir. Symptoms typically occur within the first six weeks of therapy and include fever, rash, nausea, malaise, and respiratory complaints, in various combinations. Symptoms initially may be mild but increase in severity with continued administration. Discontinuation of the medication usually resolves all signs and symptoms, but rechallenge may cause rapid onset of severe reactions, hypotension, and death. Once an abacavir hypersensitivity reaction is suspected or confirmed, it is recommended that the patient never by rechallenged with abacavir.
Hardman, J.G., L.E. Limbird, P.B., A.G. Gilman. Goodman and Gilman's The Pharmacological Basis of Therapeutics. 10th ed. New York, NY: McGraw-Hill, 2001., p. 1359
The major toxicity associated with abacavir therapy is potentially life-threatening hypersensitivity reactions. In clinical studies, hypersensitivity reactions have been reported in approximately 5% of adult and pediatric patients receiving abacavir in conjunction with lamivudine and zidovudine. Fatalities related to hypersensitivity reactions to abacavir have been reported. Manifestations of hypersensitivity usually are apparent within the first 6 weeks of abacavir therapy, but may occur at any time during therapy. Severe hypersensitivity reactions are likely to recur within hours following rechallenge in patients with a prior history of hypersensitivity to the drug, and these reactions may include life-threatening hypotension and death. The most severe hypersensitivity reactions reported to date have been in individuals who were rechallenged with abacavir after a previous hypersensitivity reaction to the drug. There also have been reports of severe or fatal hypersensitivity reactions occurring after abacavir was reintroduced in patients with no identified history of abacavir hypersensitivity or with unrecognized manifestations of hypersensitivity to the drug. Although these patients had discontinued abacavir for reasons unrelated to hypersensitivity (e.g., interruption in drug supply, discontinuance of abacavir during treatment for other medical conditions), some may have had symptoms present before discontinuance of the drug that were consistent with hypersensitivity but were attributed to other medical conditions (e.g., acute onset respiratory disease, gastroenteritis, adverse reactions to other drugs). Most of the hypersensitivity reactions reported following reintroduction of abacavir in these patients were indistinguishable from hypersensitivity reactions associated with abacavir rechallenge (i.e., short time to onset, increased severity of symptoms, poor outcome including death).Hypersensitivity reactions can occur within hours after abacavir is reintroduced; however, in some cases, these reactions occurred days to weeks following reintroduction of the drug.

Lactic acidosis and severe hepatomegaly with steatosis (sometimes fatal) have been reported rarely in patients receiving abacavir and also have been reported in patients receiving dideoxynucleoside reverse transcriptase inhibitors. Most reported cases have involved women; obesity and long-term therapy with a nucleoside reverse transcriptase inhibitor also may be risk factors. Increased serum concentrations of Gamma-glutamyltransferase (GGT, GGPT) have been reported in patients receiving abacavir.
McEvoy, G.K. (ed.). American Hospital Formulary Service - Drug Information 2003. Bethesda, MD: American Society of Health-System Pharmacists, Inc. 2003 (Plus Supplements)., p. 620
Hypersensitivity reactions reported in patients receiving abacavir are characterized by the appearance of manifestations indicating involvement of multiple organ and body systems; these reactions have occurred in association with anaphylaxis, liver failure, renal failure, hypotension, and death. The most frequent manifestations of hypersensitivity reactions to abacavir include fever, rash, fatigue, GI symptoms such as nausea, vomiting, diarrhea, and abdominal pain, and respiratory symptoms such as pharyngitis, dyspnea, and cough. Other signs and symptoms include malaise, lethargy, myalgia, myolysis, headache, arthralgia, edema, paresthesia, lymphadenopathy, and mucous membrane lesions (e.g., conjunctivitis, mouth ulceration). Respiratory symptoms, including cough, dyspnea, and pharyngitis, have been reported in approximately 20% of patients with hypersensitivity reactions to abacavir. Fatalities have occurred in patients who developed hypersensitivity reactions in which the initial presentation included respiratory symptoms; some patients who experienced fatal hypersensitivity reactions were initially diagnosed as having an acute respiratory disease (pneumonia, bronchitis, flu-like illness). Hypersensitivity reactions can occur without rash; if rash occurs, it usually is maculopapular or urticarial, but may be variable in appearance. Laboratory abnormalities reported in patients experiencing a hypersensitivity reaction to abacavir include lymphopenia and increases in serum concentrations of liver enzymes, creatine kinase (CK, creatine phosphokinase, CPK), or creatinine.

FDA Label
Ziagen is indicated in antiretroviral combination therapy for the treatment of Human Immunodeficiency Virus (HIV) infection in adults, adolescents and children.
The demonstration of the benefit of Ziagen is mainly based on results of studies performed with a twice daily regimen, in treatment-nave adult patients on combination therapy.
Before initiating treatment with abacavir, screening for carriage of the HLA-B*5701 allele should be performed in any HIV-infected patient, irrespective of racial origin. Abacavir should not be used in patients known to carry the HLA-B*5701 allele.
Abacavir is a nucleoside reverse transcriptase inhibitor (NRTI) with activity against Human Immunodeficiency Virus Type 1 (HIV-1). Abacavir is phosphorylated to active metabolites that compete for incorporation into viral DNA. They inhibit the HIV reverse transcriptase enzyme competitively and act as a chain terminator of DNA synthesis. The concentration of drug necessary to effect viral replication by 50 percent (EC50) ranged from 3.7 to 5.8 M (1 M = 0.28 mcg/mL) and 0.07 to 1.0 M against HIV-1IIIB and HIV-1BaL, respectively, and was 0.26 0.18 M against 8 clinical isolates. Abacavir had synergistic activity in cell culture in combination with the nucleoside reverse transcriptase inhibitor (NRTI) zidovudine, the non-nucleoside reverse transcriptase inhibitor (NNRTI) nevirapine, and the protease inhibitor (PI) amprenavir; and additive activity in combination with the NRTIs didanosine, emtricitabine, lamivudine, stavudine, tenofovir, and zalcitabine.

Absorption
Rapid and extensive after oral administration (83% bioavailability, tablet). When a 300 mg tablet is given twice daily to subjects, the peak plasma concentration (Cmax) was 3.0 0.89 mcg/mL and the area under the curve (AUC 0-12 hours) was 6.02 1.73 mcghr/mL.
Route of Elimination
Elimination of abacavir was quantified in a mass balance study following administration of a 600-mg dose of 14C-abacavir: 99% of the radioactivity was recovered, 1.2% was excreted in the urine as abacavir, 30% as the 5-carboxylic acid metabolite, 36% as the 5-glucuronide metabolite, and 15% as unidentified minor metabolites in the urine. Fecal elimination accounted for 16% of the dose. Renal excretion of unchanged abacavir is a minor route of elimination in humans.

Hepatic, by alcohol dehydrogenase and glucuronosyltransferase to a 5′-carboxylic acid metabolite and 5′-glucuronide metabolite, respectively. These metabolites have no antiviral activity. Abacavir is not significantly metabolized by cytochrome P450 enzymes.
Abacavir is partially metabolized by alcohol dehydrogenase (to form the 5'-carboxylic acid) and glucuronidation (to form the 5'-glucuronide).

The metabolic fate of abacavir has not been fully determined, but the drug is metabolized in the liver. Abacavir is metabolized by alcohol dehydrogenase to form the 5-carboxylic acid and by glucuronyltransferase to form the 5-glucuronide; these metabolites do not appear to have any antiviral activity. Any involvement of cytochrome p450 isoenzymes in the metabolism of abacavir is limited.

Intracellularly, abacavir is phosphorylated to abacavir monophosphate by adenosine phosphotransferase; abacavir monophosphate is then converted to carbovir monophosphate in a reaction catalyzed by cytosolic enzymes and then to carbovir triphosphate by cellular kinases. Intracellular (host cell) conversion of abacavir to carbovir triphosphate is necessary for the antiviral activity of the drug. The in vitro intracellular half-life of carbovir triphosphate in CD4+ CEM cells is 3.3 hours.

The plasma elimination half-life of abacavir following a single oral dose (given as abacavir sulfate) is about 1.5 hours. In HIV-infected children 3 months to 13 years of age who received 8 mg/kg of abacavir every 12 hours (given as an oral solution containing abacavir sulfate), steady-state plasma elimination half-life averaged 1.3 hours and was essentially the same as that reported after a single dose. Following oral administration of a single 300-mg dose of abacavir to an individual with renal failure (glomerular filtration rate less than 10 mL/minute) undergoing peritoneal dialysis, the plasma elimination half-life of the drug was 1.33 hours.

Abacavir is a carbocyclic synthetic nucleoside analogue and an antiviral agent. Intracellularly, abacavir is converted by cellular enzymes to the active metabolite carbovir triphosphate, an analogue of deoxyguanosine-5'-triphosphate (dGTP). Carbovir triphosphate inhibits the activity of HIV-1 reverse transcriptase (RT) both by competing with the natural substrate dGTP and by its incorporation into viral DNA. Viral DNA growth is terminated because the incorporated nucleotide lacks a 3'-OH group, which is needed to form the 5 to 3 phosphodiester linkage essential for DNA chain elongation.
Like dideoxynucleoside reverse transcriptase inhibitors (e.g., didanosine, lamivudine, stavudine, zalcitabine, zidovudine), the antiviral activity of abacavir appears to depend on intracellular conversion of the drug to a 5-triphosphate metabolite; thus, carbovir triphosphate (carbocyclic guanosine triphosphate) and not unchanged abacavir appears to be the pharmacologically active form of the drug. Substantial differences exist in the rates at which human cells phosphorylate various nucleoside antiviral agents and in the enzymatic pathways involved.
McEvoy, G.K. (ed.). American Hospital Formulary Service - Drug Information 2003. Bethesda, MD: American Society of Health-System Pharmacists, Inc. 2003 (Plus Supplements)., p. 621
Enzymatic conversion of abacavir to carbovir triphosphate appears to be complex and involves certain steps and enzymes that differ from those involved in the enzymatic conversion of dideoxynucleoside reverse transcriptase inhibitors. Abacavir is phosphorylated by adenosine phosphotransferase to abacavir monophosphate, which is converted to carbovir monophosphate by a cytosolic enzyme. Subsequently, carbovir monophosphate is phosphorylated by cellular kinases to carbovir triphosphate. Abacavir is not a substrate for enzymes (i.e., thymidine kinase, deoxycytidine kinase, adenosine kinase, mitochondrial deoxyguanosine kinase) known to phosphorylate other nucleoside analogs. Because phosphorylation of abacavir depends on cellular rather than viral enzymes, conversion of the drug to the active triphosphate derivative occurs in both virus-infected and uninfected cells. Carbovir triphosphate is a structural analog of deoxyguanosine-5-triphosphate (dGTP), the usual substrate for viral RNA-directed DNA polymerase. Although other mechanisms may be involved in the antiretroviral activity of the drug, carbovir triphosphate appears to compete with deoxyguanosine-5-triphosphate for viral RNA-directed DNA polymerase and incorporation into viral DNA. Following incorporation of carbovir triphosphate into the viral DNA chain instead of deoxyguanosine-5-triphosphate, DNA synthesis is prematurely terminated because the absence of the 3-hydroxy group on the drug prevents further 5 to 3 phosphodiester linkages.

The complete mechanism(s) of antiviral activity of abacavir has not been fully elucidated. Following conversion to a pharmacologically active metabolite, abacavir apparently inhibits replication of retroviruses, including human immunodeficiency virus type 1 (HIV-1) and type 2 (HIV-2), by interfering with viral RNA-directed DNA polymerase (reverse transcriptase). The drug, therefore, exerts a virustatic effect against retroviruses by acting as a reverse transcriptase inhibitor.
