/EXPERIMENTAL THER/ /Investigators/ describe five patients with HIV-2 infection (four antiretroviral-experienced and one antiretroviral-naive) treated with a regimen containing raltegravir. All responded to treatment as demonstrated by viral load and CD4(+) T-cell count monitoring. /This/ series confirms the clinical effectiveness of raltegravir in HIV-2-infected patients when given with other antiretrovirals to which the virus is susceptible.

/EXPERIMENTALTHER VET/ Feline leukemia virus (FeLV) is a gammaretrovirus that is a significant cause of neoplastic-related disorders affecting cats worldwide. Treatment options for FeLV are limited, associated with serious side effects, and can be cost-prohibitive. The development of drugs used to treat a related retrovirus, human immunodeficiency virus type 1 (HIV-1), has been rapid, leading to the approval of five drug classes. Although structural differences affect the susceptibility of gammaretroviruses to anti-HIV drugs, the similarities in mechanism of replication suggest that some anti-HIV-1 drugs may also inhibit FeLV. This study demonstrates the anti-FeLV activity of four drugs approved by the US FDA (Food and Drug Administration) at non-toxic concentrations. Of these, tenofovir and raltegravir are anti-HIV-1 drugs, while decitabine and gemcitabine are approved to treat myelodysplastic syndromes and pancreatic cancer, respectively, but also have anti-HIV-1 activity in cell culture. Our results indicate that these drugs may be useful for FeLV treatment and should be investigated for mechanism of action and suitability for veterinary use.

Severe, potentially life-threatening skin reactions have been reported, including some fatalities. Stevens-Johnson syndrome, toxic epidermal necrolysis, and hypersensitivity reactions characterized by rash, constitutional findings, and organ dysfunction (including hepatic failure) have occurred.
American Society of Health-System Pharmacists 2012; Drug Information 2012. Bethesda, MD. 2012
Raltegravir and any other suspect agents should be discontinued immediately if signs or symptoms of severe skin or hypersensitivity reactions occur, including (but not limited to) severe rash or rash accompanied by fever, general malaise, fatigue, muscle or joint aches, blisters, oral lesions, conjunctivitis, facial edema, hepatitis, eosinophilia, or angioedema. Clinical status, including liver aminotransferases, should be monitored and appropriate therapy initiated. A life-threatening reaction could occur if there is a delay in discontinuing raltegravir or other suspect agents after the onset of severe rash.
American Society of Health-System Pharmacists 2012; Drug Information 2012. Bethesda, MD. 2012
During initial treatment, patients who respond to antiretroviral therapy may develop an inflammatory response to indolent or residual opportunistic infections (e.g., Mycobacterium avium, M. tuberculosis, cytomegalovirus (CMV), Pneumocystis jiroveci (formerly P. carinii), varicella-zoster virus (VZV)); this may necessitate further evaluation and treatment. Autoimmune disorders (e.g., Graves' disease, polymyositis, Guillain-Barre syndrome) have been reported to occur in the setting of immune reconstitution; the time to onset is more variable and can occur many months after initiation of antiretroviral therapy.

Individuals with phenylketonuria (i.e., homozygous genetic deficiency of phenylalanine hydroxylase) and other individuals who must restrict their intake of phenylalanine should be advised that raltegravir chewable tablets contain aspartame (NutraSweet), which is metabolized in the GI tract to phenylalanine. Each 25-mg chewable tablet provides approximately 0.05 mg of phenylalanine and each 100-mg chewable tablet provides approximately 0.1 mg of phenylalanine.

Absorption
Absorbed from the gastrointestinal tract.
Route of Elimination
Feces and urine
Volume of Distribution
Approximately 83% bound to human plasma protein and is minimally distributed into red blood cells (blood-to-plasma partitioning ratio of 0.6).
Clearance
The major mechanism of clearance of raltegravir in humans is glucuronidation mediated by UGT1A1, the renal clearance of unchanged drug is a minor pathway of elimination of raltegravir (9% of total dose).
Raltegravir (film-coated tablet) is absorbed with a Tmax of approximately 3 hours postdose in the fasted state. Raltegravir AUC and Cmax increase dose proportionally over the dose range 100 mg to 1600 mg. Raltegravir C12hr increases dose proportionally over the dose range of 100 to 800 mg and increases slightly less than dose proportionally over the dose range 100 mg to 1600 mg.

With twice-daily dosing, pharmacokinetic steady state is achieved within approximately the first 2 days of dosing. There is little to no accumulation in AUC and Cmax. The average accumulation ratio for C12hr ranged from approximately 1.2 to 1.6.

The absolute bioavailability of raltegravir has not been established. Based on a formulation comparison study in healthy adult volunteers, the chewable tablet has higher oral bioavailability compared to the 400 mg film-coated tablet.

Hepatic (UGT1A1)
In feces, only raltegravir was present, most of which is likely derived from hydrolysis of raltegravir-glucuronide secreted in bile as observed in preclinical species. Two components, namely raltegravir and raltegravir-glucuronide, were detected in urine and accounted for approximately 9 and 23% of the dose, respectively. The major circulating entity was raltegravir and represented approximately 70% of the total radioactivity; the remaining radioactivity in plasma was accounted for by raltegravir-glucuronide.
US Natl Inst Health; DailyMed. Current Medication Information for ISENTRESS (raltegravir) tablet, film coated; tablet, chewable (Janurary 2013). Available from, as of March 14, 2013: https://dailymed.nlm.nih.gov/dailymed/lookup.cfm?setid=89a5ec53-d956-4329-8004-0f40f51c88a3
Studies using isoform-selective chemical inhibitors and cDNA-expressed UDP-glucuronosyltransferases (UGT) show that UGT1A1 is the main enzyme responsible for the formation of raltegravir-glucuronide. Thus, the data indicate that the major mechanism of clearance of raltegravir in humans is UGT1A1-mediated glucuronidation.

9 hours
The apparent terminal half-life of raltegravir is approximately 9 hours, with a shorter alpha-phase half-life (approximetly1 hour) accounting for much of the AUC.

Raltegravir inhibits HIV integrase to prevent the viral genome being incorporated into the human genome. Raltegravir is primarily metabolized by glucuronidation.
Raltegravir inhibits the catalytic activity of HIV-1 integrase, an HIV-1 encoded enzyme that is required for viral replication. Inhibition of integrase prevents the covalent insertion, or integration, of unintegrated linear HIV-1 DNA into the host cell genome preventing the formation of the HIV-1 provirus. The provirus is required to direct the production of progeny virus, so inhibiting integration prevents propagation of the viral infection. Raltegravir did not significantly inhibit human phosphoryltransferases including DNA polymerases alpha, beta, and gamma.
