Viracept Protease Inhibitor
Yes: The HIV mutates frequently, and when a mutation produces resistance to protease inhibitors this will allow that form of the virus to multiply over other forms which are sensitive. That is one of the reasons for a drug combination which makes single mutational changes less likely to be favorable to the virus. ...Read more
Anti-HIV: Yes, but more better tolerated combinations exist. ...Read more

So a cox-2 inhibitor is, in effect, a pain blocker. ...Read more
