Disclosed herein are DKP microcrystals made by an improved method where they do not irreversibly self-assemble into microparticles. The microcrystals can be dispersed by atomization and re-formed by spray drying into particles having spherical shell morphology. Active agents and excipients can be incorporated into the particles by spray drying a solution containing the components to be incorporated into microcrystalline diketopiperazine particles. In particular, the microcrystalline particle compositions are suitable for pulmonary drug delivery of one or more peptides, proteins, nucleic acids and/or small organic molecules.

The invention provides oral dosing regimens of controlled release levodopa compositions for use in treating patients with Parkinson's disease.

The present invention relates to a new delivery system for PUFAs.

The present invention relates to a new delivery system for specific water-soluble vitamins.

A granular product based on arginine or the derivatives thereof, comprises an internal core in which there is substantially concentrated the arginine and a coating for covering and protecting the internal core, wherein the coating is formed by a lipidic matrix comprising a fraction by weight equal to or greater than 60% of glycerides of saturated fatty acids C16 and C18 and a fraction by weight of a mineral salt of alginate between 0.5% and 3%.

Provided is a core-shell structure that can achieve both improvement in transdermal absorption of an active ingredient and reduction in skin irritation at a high level. A core-shell structure 10 includes: a core portion 11 containing an active ingredient, the core portion being solid; and a shell portion 12 containing both a first surfactant having a melting point of less than 35° C. and a second surfactant having a melting point of 35° C. or more, the first surfactant and the second surfactant each having an HLB value of 4 to 14, the first surfactant and the second surfactant each containing at least one selected from the group consisting of sorbitan fatty acid esters, glycerin fatty acid esters, propylene glycol fatty acid esters, and fatty acid alkanolamides.

Embodiments of the present disclosure provide novel compositions, methods of use and methods for single composition, multi-dose, thermostable vaccine formulations. In certain embodiments, the present disclosure provides compositions and methods for dehydrating immunogenic agents in the presence of glass-forming agents, and coating the particles formed by the glass-forming agents. In other embodiments, the present disclosure provides for generating compositions for administering an immunogenic composition to a subject multiple times using a single immunogenic composition capable of time-release administration. In other embodiments, single-dose immunogenic agent-containing particles can be directed to two or more pathogens. In other embodiments, incompatible immunogenic agents against two or more different pathogens of immunogenic agent-containing particles disclosed herein can be mixed together and coated for timed-release administration to produce single-administration formulations capable of eliciting an immune response to the two or more pathogens in a subject.

Encapsulated particles comprising one or more particle cores of silicon-containing material, wherein the one or more particle cores are encapsulated in a waxy lipid shell comprising: a) two lipidic components present at from 55% to 95% of the total encapsulated particle weight; b) a surfactant present at from 0.1% to 5% by weight of the total encapsulated particle weight; c) a co-surfactant present at from 0.01% to 1% by weight of the total encapsulated particle weight; d)a regulator of metastable state present at from 0.1% to 5% by weight of the total encapsulated particle, wherein the regulator of metastable state is selected from one or more of: the terpenes; the terpenoids; fatty acids, from myristic to docosanoic, pegylated by methyl ether of polyethylene glycol (PEG. Me M. W. 750-2000); diacylphosphatidylethanolamines pegylated with PEG;poloxamers (Pluronics); and derivatives thereof. Also related compositions and methods.

The present invention relates to a rumen-resistant composition in the form of microgranules, a process for its production and a feedstuff containing such composition.

This disclosure provides pharmaceutical compositions comprising midodrine, a pharmaceutically acceptable salt thereof, desglymidodrine, a pharmaceutically acceptable salt thereof, or a combination therefore that can be administered to a human subject in need thereof in a supine position. The disclosure also provides pharmaceutical compositions which can be administered once-a-day. This disclosure further provides pharmaceutical compositions comprising an extended release composition and providing a delayed release period between about 30 min to about 12 hours.
