Nirmatrelvir is an oral protease inhibitor that is active against MPRO, a viral protease that plays an essential role in viral replication by cleaving the 2 viral polyproteins.1 It has demonstrated antiviral activity against all coronaviruses that are known to infect humans.2 Nirmatrelvir is packaged with ritonavir (as Paxlovid), a strong cytochrome P450 (CYP) 3A4 inhibitor and pharmacokinetic boosting agent that has been used to boost HIV protease inhibitors. One of the reasons for this difference is that infections trigger many different parts of the immune system, and the size of the antibody response will depend on factors like how much virus you inhaled, whether you have underlying medical conditions and the severity of your symptoms.

CYP3A4 inhibition occurs rapidly after initiating ritonavir, with maximum inhibition occurring within 48 hours.28 After ritonavir is discontinued, 70% to 90% of CYP3A4 inhibition resolves within 2 to 3 days.29 The time to resolution of inhibition varies based on factors such as the patients age; therefore, resolution may take longer in some individuals, such as in adults of advanced age.
