stockpeeker, nice summary ...
Anti-Virals
Tamiflu - Roche. Also Gilead licenesed to Roche, and is going to court trying to get it back, claiming Roche did not effectively market it.
Relenza - I think GSK, and I believe also licensed from another co., can't think of it at them moment
Off-Patent Amantitidines, effective against some strains
Symmetrel (Endo)
Flumandine (Forrest Labs)
Mutations will continue, and other anti-virals will be effective against different strains
