What are Paxzen Tablets – Nirmatrelvir 150mg and Ritonavir 100mg?

Paxzen is an antiviral drug under study approved for emergency use, containing the active ingredients nirmatrelvir 150 mg and ritonavir 100 mg. Paxzen is indicated for the treatment of mild to moderate coronavirus disease in adult and pediatric patients (> 12 years and body weight > 40 kg) who test positive for the SARS-CoV-2 virus and are at high risk of developing, including hospitalization or death.

Paxzen Nirmatrelvir is an important protease inhibitor of SARS-CoV-2. It works by preventing the growth of the virus that causes COVID-19. Ritonavir increases (“boosts”) levels of Nirmatrelvir. This helps nirmatrelvir work better. For more information about nirmatrelvir and ritonavir, see the FDA Emergency Information Sheet for Patients, Parents and Carers and the Health Canada Drug Patient Information Sheet.

Information about how safe and effective the combination of Nirmatrelvir and ritonavir is to treat COVID-19 is limited. Study results suggest that Paxzen Nirmatrelvir and ritonavir can help people who have recently tested positive for the coronavirus leave the hospital. This product should not be used by people who are hospitalized with COVID-19.

The information in this document reflects new, evolving data and is subject to re-evaluation. Users should be aware of these considerations in their reviews of Nirmatrelvir and Ritonavir, and it is always the responsibility of the treating physician to exercise independent judgment in making treatment decisions.

Ritonavir is used with Nirmatrelvir because it acts as a pharmacokinetic enhancer, resulting in higher systemic concentrations and a longer half-life of Nirmatrelvir, thereby maintaining a twice-daily dosing regimen.
