Naivex
Drug profile of Naivex
Naivex tablet are an anti-retro viral medicine, which containing an anti-retroviral agent known as Dolutegravir.Dolutegravir is a termed as DTG used in HIV-1 infection, classified as an integrase inhibitor.
Dolutegravir is generally used in combination with other anti-retroviral drugs for improved results.
Naivex are used for reducing the progression of infection to AIDS, but not for curing the infections.
Dolutegravir binds to infected cells, block the integration process and prevents the further formation of cells.
Naivex tablet is pharmacologically categorized as;
Human immuno deficiency virus integrase strand transfer inhibitor.
Naivex are prescription medicine, used only in HIV infected patients with proper prescription under the knowledge of medical practitioner.

1. Dolutegravir Naivex tablet prohibits the renal organic cation transporter, OCT2 in-vitro.
2. Dolutegravir prohibits tubular secretion of creatinine by obstructing OCT2 in-vivo.
3. Co administration of dofetilide or metformin (drugs excreted through OCT2), causes increasing plasma concentration of these drugs.
4Naivex combined with drugs which induces UGT1A3, UGT1A9, BCRP & P-gp enzymes & transporters may leads to deplete the Naivex tablet plasma concentration.
5. Concurrent use of Naivex with drugs which inhibits these above meioned enzymes, causes increasing concentration of Dolutegravir.
6. Dolutegravir plasma concentration may reduced by etravirine.
7. Naivex tablet with nevirapine causes decreasing the effect of concentration of Dolutegravir.
8. Naivex co administered with protease inhibitors like fosamprenavir/ritonavir, tipranavir/ritonavir; causes decreasing the effect of concentration of Dolutegravir.
