The present invention relates to a liposomal composition for use as a medicament. In particular, the present invention relates to a liposomal composition for use in prevention or early treatment of pathogenic infection. More specifically, the liposomal composition is used for prevention, or early treatment, of pathogenic infection in the respiratory tract, preferably by nasal or pulmonary administration.

Viral epidemic infections due to influenza, or coronaviruses, particularly influenza A and SARS-CoV-1 and -2 virus cause significant morbidity and mortality. The significant mutation rate of this group of viruses renders existing vaccines or antiviral drugs often useless, creating a need for broad acting, viral DNA or RNA sequence independent antiviral drugs. This invention describes the repurposing of methylene blue and riboflavin, two FDA approved drugs with an excellent safety profile. Using a virus neutralization assay of H1N1 Influenza A and SARS-CoV-2, the significant viricidal activity of both drugs at pharmacological dose and under physiological conditions is demonstrated. In vivo prophylactic and therapeutic use of the drugs for anti-viral application in an animal model is described.

The disclosure provides a rapidly deployable nanoscale biodegradable system using hydroxypropyl beta cyclodextrin based combination product. Cyclodextrin is an amphiphilic polymer suitable to develop an agnostic barrier blocking pathogenic mi-crobes that has localized on the mucocutaneous lining of the conjunctiva, mouth and nose, lung, or gastrointestinal tract. The cyclodex-trin may bind the viral particles and/or disrupt viral entry mechanisms by removing cholesterol from viral particles to reduce infectivity. Cyclodextrins also may facilitate removal of the viral cholesterol molecules, thus rendering them less viable. Cyclodextrin activity may be further enhanced when used in combination with certain minerals and/or antioxidant compounds.

A synergistic non-toxic formulation for management of respiratory pathogens including coronaviruses and the process of preparing the synergistic formulation. The effective, non-toxic composition comprises of biological peptides including calcium chelating peptide and zinc chelating peptides, protease inhibitor such as 9-Arginine-peptide and inhibitor of viral replication enzyme such as vitamin B12 to reduce the presence of respiratory viruses including coronaviruses. The formulation is a cocktail of ingredients having a synergistic effect which is capable of being administered through various means including by way of inhalation, as nasal spray or an oral pump or via nebulizer to inhibit the entry and replication of respiratory pathogens. The combination of the formulation is such that it can be customized for a number of viral infections. The formulation is economical, self-administrable and effective even in low doses.

A paranasal and/or nasal delivery system that includes a thermoresponsive gel; and a plurality of microparticles comprising a therapeutic amount of at least one paranasal and/or nasal condition-treating therapeutic agent, wherein the microparticles are included in the thermoresponsive gel.

The subject invention provides materials methods for reducing infections in subjects. The materials methods utilize chlorhexidine, which has been found to be surprisingly non-toxic. The lack of toxicity facilitates the use of chlorhexidine in contexts that were not previously thought to be possible.

Described herein are methods for treating rhinosinusitis by administering to the subject an effective amount of verapamil and mometasone as well as compositions and kits for treating rhinosinusitis.

The present system is directed in several embodiments to a method of administration of a therapeutic composition for protection of the brain of a subject at risk of injury leading to traumatic brain injury (TBI) and/or treatment of injury to the brain resulting from TBI. The method includes administering one or more therapeutic compositions comprising an effective amount of insulin directly to the subject patient's CNS, with no to minimal systemic exposure. Preferably, this method comprises administration of an effective amount of insulin to the upper third of a patient's nasal cavity, thereby bypassing the patient's blood-brain barrier and delivering the therapeutic composition directly to the patient's central nervous system.

The invention relates to a method of inhibiting viral replication by topically administering imiquimod, {1-(2-methylpropyl)-1H-imidazo[4,5-c]-quinolin-4-amine} or by administering imiquimod cocrystals (made with ferulic, acetic, tartaric, citric or coumaric acid). Another aspect of the invention is a method of preventing or reducing the severity of an infection by topically administering by imiquimod, or one of these cocrystals. Another aspect is administering imiquimod or one of these cocrystals in a nasal spray.
