Pathophysiologically, it aims to intercept and suppress viral attachment, cellular entry, or early viral replication before SARS-CoV-2 establishes systemic dissemination and triggers acute inflammatory cascades, thereby preventing symptomatic coronavirus disease 2019 and associated lower respiratory tract complications
