- Brand products Invirase (capsules) and Fortovase (soft gelatin capsules) are not bioequivalent and are not interchangeable. When using saquinavir as part of an antiviral regimen, FORTOVASE is the recommended formulation. In rare circumstances, INVIRASE may be considered if it is to be combined with antiretrovirals that significantly inhibit saquinavir's metabolism.
