Insights
Nirmatrelvir-ritonavir (NMVr) treats high-risk COVID-19 patients. Co-administration with cardiovascular drugs may cause dangerous interactions due to ritonavir
Area of Science:
- Pharmacology
- Cardiology
- Infectious Diseases
Background:
- Nirmatrelvir-ritonavir (NMVr) is a key treatment for nonhospitalized, high-risk COVID-19 patients.
- Patients with cardiovascular disease (CVD) are at higher risk for severe COVID-19 and more likely to receive NMVr.
- Ritonavir, a component of NMVr, inhibits CYP3A4, CYP2D6, and P-glycoprotein, impacting drug metabolism.
Purpose of the Study:
- To review potential drug-drug interactions (DDIs) between NMVr and common cardiovascular medications.
- To highlight the clinical significance of these interactions for patient safety.
- To inform healthcare providers on managing concurrent NMVr and cardiovascular therapy.
Main Methods:
- Review of pharmacokinetic and pharmacodynamic properties of NMVr and cardiovascular drugs.
- Analysis of known interactions involving ritonavir as a CYP3A4 and P-glycoprotein inhibitor.
- Identification of cardiovascular medications frequently co-prescribed with NMVr.
Main Results:
- Significant potential for DDIs exists between NMVr and various cardiovascular medications.
- Inhibition of CYP3A4 and P-glycoprotein by ritonavir can alter the efficacy and toxicity of cardiovascular drugs.
- Specific examples of high-risk cardiovascular drug classes requiring careful consideration are discussed.
Conclusions:
- Awareness of NMVr-cardiovascular drug interactions is critical for preventing adverse events.
- Close monitoring and potential dose adjustments of cardiovascular medications are necessary during NMVr treatment.
- Proactive management strategies are essential to ensure patient safety in this vulnerable population.
Abstract:
Nirmatrelvir-ritonavir (NMVr) is used to treat symptomatic, nonhospitalized patients with coronavirus disease-2019 (COVID-19) who are at high risk of progression to severe disease. Patients with cardiovascular risk factors and cardiovascular disease are at a high risk of developing adverse events from COVID-19 and as a result have a higher likelihood of receiving NMVr. Ritonavir, the pharmaceutical enhancer used in NMVr, is an inhibitor of the enzymes of CYP450 pathway, particularly CYP3A4 and to a lesser degree CYP2D6, and affects the P-glycoprotein pump. Co-administration of NMVr with medications commonly used to manage cardiovascular conditions can potentially cause significant drug-drug interactions and may lead to severe adverse effects. It is crucial to be aware of such interactions and take appropriate measures to avoid them. In this review, we discuss potential drug-drug interactions between NMVr and commonly used cardiovascular medications based on their pharmacokinetics and pharmacodynamic properties.

Antianginal Drugs: Nitrates and β-Blockers
Organic nitrates, such as nitroglycerin, play a pivotal role. Once metabolized, they liberate nitric oxide, a molecular marvel. Nitric oxide triggers guanylyl cyclase and augments cGMP production. This biochemical cascade orchestrates the relaxation of vascular smooth muscles, ushering in vasodilation and enhancing coronary blood flow. Administered...
