Remarks: Raltegravir is a novel HIV-1 integrase strand transfer inhibitor with potent in vitro activity against wild-type and multi-class resistant HIV-1 virus (in vitro IC95 for HIV-1 in 50% normal human serum = 33 nM). Inhibition of integrase prevents insertion of HIV DNA into the human DNA genome, thus blocking the ability of HIV to replicate. Raltegravir is administered orally every 12h and does not require boosting with low-dose ritonavir (RTV) to achieve therapeutic concentrations. Raltegravir is not a potent inhibitor or inducer of cytochrome P450 3A4, and it is predominantly metabolized by glucuronidation, specifically by the enzyme UDP-glucuronosyltransferase 1A1
None of the products will be supplied to countries in which this could be in conflict with the existing patents. However the final responsibility lies with the Buyer.
