Described herein is the finding that hyaluronan antagonists that inhibit hyaluronan signaling are capable of inhibiting airway inflammation and airway hyperresponsiveness (AHR). The present disclosure provides a method of preventing or reducing AHR in a subject suffering from or at risk for AHR by administering a hyaluronan antagonist. Also provided is a method of treating an airway disease or disorder in a subject by administering a hyaluronan antagonist. Hyaluronan antagonists include, for example, heparosan and hyaluronan oligosaccharides (oHAs). In some embodiments, the hyaluronan antagonist is administered locally to the airway, such as with an inhaler or nebulizer.

Aerosol formulations of ondansetron useful for pulmonary delivery are provided. The formulations are useful in the reduction, elimination or prevention of nausea and vomiting associated with chemotherapy, radiation therapy, and surgery. Also provided are novel methods to treat chemotherapy-induced nausea and vomiting (CINV), radiation-induced nausea and vomiting (RINV), and post-operative nausea and vomiting (PONV) using the inhalation formulations.

The present invention provides processes for preparing suspension aerosol formulations, wherein the particles for inhalation are formed in situ during the process of manufacturing the formulation. In one aspect of the invention, a process for preparing a suspension aerosol formulation comprises the steps of: (a) dissolving one or more medicaments in one or more solvents to form a solution; and (b) mixing one or more propellants with the solution under conditions effective to precipitate, entirely or partially, at least one of the medicaments.

The invention includes methods of preventing or treating acute lung injury using a MAP3K2/MAP3K3 inhibitor. The invention further comprises compositions, and kits comprising compositions useful within the invention.

Stable composition of anhydrous micronized ipratropium or a pharmaceutically acceptable anhydrous salt thereof and method of making.

The present disclosure provides for palonosetron formulations, such as aerosol formulations of palonosetron for pulmonary delivery. Also provided are uses of the formulation, such as reduction, elimination or prevention of nausea and vomiting associated with chemotherapy, radiation therapy, or surgery. Also provided are novel methods to treat chemotherapy-induced nausea and vomiting (CINV), radiation-induced nausea and vomiting (RINV), and post-operative nausea and vomiting (PONV) using the inhalation formulations.

A method of charging a container for use in a medication delivery apparatus wherein the propellant used comprises 1,1-difluoroethane (R-152a) is described.

The invention provides a compound of formula I: (I) or a pharmaceutically acceptable salt thereof, wherein R.sup.1-R.sup.5 Y have any of the values described in the specification, as well as compositions comprising a compound of formula I. The compounds are useful to treat malaria.

##STR00001##

A pharmaceutical composition is described. The composition may include a drug component and a propellant component. The drug component comprises at least one pharmaceutically acceptable salt of glycopyrrolate and at least one long acting beta-2-agonist (LABA) selected from formoterol and the pharmaceutically acceptable salts thereof. At least 90 weight % of the propellant component is 1,1-difluoroethane (HFA-152a).

The disclosure relates to a method for treating a viral pulmonary infection (e.g., COVID-19 infection), the method comprising the step of delivering a composition comprising at least one bronchodilator or a pharmaceutically acceptable salt thereof and at least one pulmonary surfactant or a pharmaceutically acceptable salt thereof to the airway of a subject in need of treatment for the pulmonary viral infection.
