Following on from providing two listings for darunavir according to whether it is used with cobicistat or ritonavir, we have now split atazanavir into three options.
Like darunavir, atazanavir can be used with either cobicistat or ritonavir, but in addition it is licensed in some geographical regions for use without a pharmacokinetic enhancer in certain patients.
Atazanavir now appears on the interaction checker as atazanavir alone (Reyataz), atazanavir/cobicistat (coformulated as Evotaz), and atazanavir + ritonavir (available as Reyataz + Norvir).
