This is just a small copy and paste about isentress from wikipedia that i think is of interest to many of us. Research on human cytomegalovirus (HCMV) terminase proteins demonstrated that Raltegravir may block viral replication of the herpesviruses. In January 2013, a Phase II trial was initiated to evaluate the therapeutic benefit of raltegravir in treating multiple sclerosis (MS). The drug is active against Human Endogenous Retroviruses (HERVs) and possibly Epstein-Barr Virus, which have been suggested in the pathogenesis of relapsing-remitting MS. I dont know if isentress would be stronger then say valcyte but it would be interesting if someone new?? cheers!!!
