The patient should not double the dose to make up for a missed dose.

Interaction of Paxovir 150 mg+100 mg

Co-administration of this tablet with drugs highly dependent on CYP3A for clearance and for which elevated plasma concentrations are associated with serious and/or life-threatening events is contraindicated. Co-administration with other CYP3A substrates may require a dose adjustment or additional monitoring. Nirmatrelvir and Ritonavir are CYP3A substrates; therefore, drugs that induce CYP3A may decrease Nirmatrelvir and Ritonavir plasma concentrations and reduce this tablet therapeutic effect.

Contraindications

History of clinically significant hypersensitivity reactions to the active ingredients (Nirmatrelvir or Ritonavir) or any other components. Co-administration with drugs highly dependent on CYP3A for clearance and for which elevated concentrations are associated with serious and/or life-threatening reactions. Co-administration with potent CYP3A inducers where significantly reduced Nirmatrelvir or Ritonavir plasma concentrations may be associated with the potential for loss of virologic response and possible resistance.

Side Effects of Paxovir 150 mg+100 mg

Adverse events (incidence >1% and subject difference) were dysgeusia, diarrhea, hypertension, and myalgia.

Precautions & Warnings

Storage Conditions

Mode Of Action

This inhibits the main protease (Mpro) of the SARS-CoV-2. This main protease (Mpro) is also referred as 3C-like protease (3CLpro) or nsp5 protease. This inhibition of Mpro hampers the peptidomimetic activity of SARS-CoV-2. Ritonavir is an HIV-1 protease inhibitor but is not active against SARS-CoV-2 Mpro. Ritonavir inhibits the CYP3A mediated metabolism of Nirmatrelvir, resulting in increased plasma concentrations of Nirmatrelvir

Pregnancy

This is not recommended during pregnancy and in people who can become pregnant and who are not using contraception. Breastfeeding should be interrupted during treatment. These recommendations are because laboratory studies in animals suggest that high doses of this may impact the growth of the fetus. This drug should be used during pregnancy only if clearly needed and the benefit outweighs the risk to the fetus; use of oral solution is not recommended.
