Ritonavir is thus used to deliberately inhibit CYP3A4 and perpetrate a DDI on nirmatrelvir, effectively boosting the PK of the latter to therapeutic levels. It’s a marriage of convenience that turns an also-ran molecule into a drug. 7/ https://t.co/SfgD9XovV0

@_KJKelly @USMortality Indeed. It has nothing to do with HIV. Ritonivir (RTV) slows the metabolism of the anti-viral compound PF-07321332 (nirmatrelvir), ensuring its concentration remains high enough to be effective significantly longer then it would otherwise. https://t.co/l4atFgXMND https://t.co/tMYCu3khB4
