Abstract: Compositions including at least one nuclear steroid family (NSF) receptor antagonist for the treatment or prevention of a coronavirus infection, such as SARS-CoV-2, and for the treatment of symptoms resulting from such infection. Also provided herein are methods of administering such compounds to a patient, either in a combination pharmaceutical formulation or in separate pharmaceutical formulations, to treat or prevent viral infections, including viral infections from coronaviruses such as SARS-CoV-2. Treatment decreases a viral load in a subject and/or may ameliorate symptoms associated with or produced by viral infection. Various administration modalities and mechanisms may be selected depending upon a condition of a patient and the patient's ability to be administered via a selected modality.
