4/The 'molecular scissor' that frees up these proteins is called a protease. If these proteins aren't separated from each other by the protease the virus becomes defective. Paxlovid grabs the protease and neutralizes it & stops the virus from replicating. https://t.co/fTC1PZxqGP

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

La 'tijera molecular' que libera estas proteínas se llama proteasa. Si estas proteínas no están separadas entre sí por la proteasa, el virus se vuelve defectuoso. Paxlovid toma la proteasa y la neutraliza y evita que el virus se replique. https://t.co/vLWB9YKr6f

@_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

https://t.co/qp5s0ufYT8 ファイザーの経口摂取可能なコロナ治療薬PF-07321332 (パクスロリド) これからは治療薬が必要になるからね 本当に素晴らしい 代謝安定性が低いからリトナビル併用で 少し制限があるけど しっかりと血中濃度が維持されて活性がある
