Microparticulate drug compositions comprising nanocrystals of poorly soluble drugs combined with a carrier are disclosed. Also disclosed are pharmaceutical compositions that include the microparticulate drug compositions. Further disclosed are methods of preparing and using the microparticulate drug compositions/pharmaceutical compositions.

The present technology relates generally to dry powder formulations comprising leucine and trileucine in specific ratios that are suitable for pulmonary delivery. Also provided are methods of preparing the dry powder formulations, and methods of administration and treatment using the dry powder formulations.

Summary

The invention relates to powdered pharmaceutical formulations which, in addition to carrier particles and particulate active ingredient which preferably adheres to the surface of the carrier particles, contains a mixing element, wherein the formulation fluidized in the carrier gas stream can contain the mixing element. Preferably, the powdered pharmaceutical formulation is packaged as a single dose, for example filled into a container as a single dose, for example in a capsule. The mixing element has a size of at least 1 mm to 10 mm in a first dimension and a size of at least 50% of the size it has in the first dimension in the other two dimensions.

There is provided a tobacco flavoured dry powder formulation comprising a plurality of particles comprising a base material and a tobacco flavouring composition, wherein a first ratio by weight of (β-ionone+β-damascenone) to (phenol) in the tobacco flavoured dry powder formulation is greater than 0.25. Further, there is provided a method of producing one such tobacco flavoured powder formulation. The method comprises the steps of: preparing a tobacco starting material; heating the tobacco starting material at an extraction temperature of between 100 degrees Celsius and 160 degrees Celsius for at least 90 minutes; collecting the volatile compounds released from the tobacco starting material during the heating step; forming a liquid tobacco flavouring composition comprising the collected volatile compounds; combining a base material and the liquid tobacco flavouring composition to form tobacco flavoured particles.

Provided herein are dry powder formulations comprising epinephrine alone or in combination with at least one enabling agent suitable for nasal application. Also provided are unit dose forms and devices comprising such formulations and methods of using such formulations for the treatment of various conditions including anaphylaxis, anaphylactoid reaction, respiratory conditions, hemodynamic collapse, and for administration during cardiopulmonary arrest and other life-threatening conditions.

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 (PONY) using the inhalation formulations.

The present disclosure relates to TGF-beta antibodies and binding fragments thereof, DNA encoding the same, host cells comprising said DNA and methods of expressing the antibody or binding fragment in a host cell. The disclosure also extends to pharmaceutical compositions comprising the antibody or a binding fragment thereof and use of the antibody, binding fragment and compositions comprising the same in treatment of various diseases including fibrosis.

This disclosure relates to a method of treating, preventing, or reducing a symptom of a virus infection, including a SARS-CoV-2 infection, by administering an effective amount of tdsRNA optionally with an anti-viral agent, to a subject.

Dry powder formulations for pulmonary and/or intranasal drug delivery, delivery systems, and methods of making and using thereof have been developed. The dry powder formulation contains particles containing a retinoid and/or a retinoid derivative, such as tamibarotene; and a β-cyclodextrin and/or a β-cyclodextrin derivative. The dry powder formulation allows for improved drug adsorption and bioavailability in vivo. The particles of the dry powder formulation have favorable aerodynamic properties for deposition and retention in the lower and/or upper respiratory tract(s). The dry powder formulation can be prepared using spray-drying or spray-freeze-drying. Inhalation, intratracheal administration, and/or intranasal administration of the dry powder formulation can deliver to a subject an effective amount of the retinoid and/or retinoid derivative to prevent, treat, or ameliorate symptom(s) associated with a respiratory viral infection in the subject.

The present invention provides a particulate delivery device with an automatic activation mechanism that pierces or cuts a composition capsule when a cap is removed. The cap cannot be replaced once the device is activated for use. The device allows for gas flow through the device from a gas inlet to a gas outlet through a composition receptacle and dispersion chamber to deliver particulate to the airway of a subject.
