Population pharmacokinetic/pharmacodynamic modelling to evaluate favipiravir in combination with lopinavir–ritonavir in patients with COVID‐19

British Journal of Clinical Pharmacology, EarlyView.
Aims The repurposed use of favipiravir in COVID‐19 has been reported to have limited clinical efficacy, yet it has been widely used in some countries. Favipiravir causes mutagenesis in RNA viruses, and it is currently unknown whether it may have a measurable effect on the virus in humans.

Early administration of nirmatrelvir/ritonavir leads to faster negative SARS-CoV-2 nasal swabs than monoclonal antibodies in COVID 19 patients at high-risk for severe disease [PDF]

Purpose Besides the well-established efficacy in preventing severe COVID-19, the impact of early treatments, namely antivirals and monoclonal antibodies (mAbs), on the time length to negativization of SARS-CoV-2 nasal swabs is still unclear.

Safety, Pharmacokinetics, and Dose Recommendations for Nirmatrelvir/Ritonavir in Individuals with Mild to Moderate COVID‐19 and Severe Renal Impairment

Clinical Pharmacology &Therapeutics, EarlyView.
Patients with severe renal impairment and COVID‐19 are at high risk for severe disease and death. Nirmatrelvir/ritonavir, an antiviral therapy for COVID‐19, is eliminated by renal excretion and can accumulate in patients with severe renal impairment.

Nirmatrelvir/Ritonavir Utilization for the Treatment of Non-hospitalized Adults with COVID-19 in the National Veterans Affairs (VA) Healthcare System

Infectious Diseases and Therapy
Introduction Limited data exist regarding real-world utilization of nirmatrelvir/ritonavir. We identified predictors of nirmatrelvir/ritonavir use among Veterans Affairs (VA) outpatients nationally. Methods We conducted a retrospective cohort study among

The anti-COVID-19 drug nirmatrelvir crosses the blood‒brain barrier and exhibits herb–drug pharmacokinetic interactions with Scutellaria baicalensis formulations

Heliyon
Aim of the study: Our hypothesis is that nirmatrelvir can penetrate the blood‒brain barrier and reach effective concentrations in the brain. Furthermore, herbal formulations can help maintain nirmatrelvir levels in the body, suggesting potential ...

The protease inhibitor Nirmatrelvir synergizes with inhibitors of GRP78 to suppress SARS-CoV-2 replication [PDF]

Nirmatrelvir, the active compound of the drug Paxlovid, inhibits the Main protease of SARS-CoV-2 (MPro, 3CLPro, NSP5). Its therapeutic application reduces but does not abolish the progression of COVID-19 in humans.

Development of a physiologically‐based pharmacokinetic model for Ritonavir characterizing exposure and drug interaction potential at both acute and steady‐state conditions

CPT: Pharmacometrics &Systems Pharmacology, Volume 14, Issue 3, Page 523-539, March 2025.
Abstract Ritonavir (RTV) is a potent CYP3A inhibitor that is widely used as a pharmacokinetic (PK) enhancer to increase exposure to select protease inhibitors. However, as a strong and complex perpetrator of CYP3A interactions, RTV can also enhance the exposure of other co‐administered CYP3A substrates, potentially causing toxicity.
