A method of preparing a pharmaceutical composition having a drug-containing core enclosed by one or more metal oxide materials is provided. The method includes the sequential steps of (a) loading the particles comprising the drug into a reactor, (b) applying a vaporous or gaseous metal precursor to the particles in the reactor, (c) performing one or more pump-purge cycles of the reactor using inert gas, (d) applying a vaporous or gaseous oxidant to the particles in the reactor, and (e) performing one or more pump-purge cycles of the reactor using inert gas. The temperature of the particles does not exceed 35° C. This produces a pharmaceutical composition comprising a drug containing core enclosed by one or more metal oxide materials.

The present invention relates generally to vesicles such as liposomes, colloidosomes, and polymersomes, as well as techniques for making and using such vesicles. In some cases, the vesicles may be at least partially biocompatible and/or biodegradable. The vesicles may be formed, according to one aspect, by forming a multiple emulsion comprising a first droplet surrounded by a second droplet, which in turn is surrounded by a third fluid, where the second droplet comprises lipids and/or polymers, and removing fluid from the second droplet, e.g., through evaporation or diffusion, until a vesicle is formed. In certain aspects, the size of the vesicle may be controlled, e.g., through osmolarity, and in certain embodiments, the vesicle may be ruptured through a change in osmolarity. In some cases, the vesicle may contain other species, such as fluorescent molecules, microparticles, pharmaceutical agents, etc., which may be released upon rupture. Yet other aspects of the invention are generally directed to methods of making such vesicles, kits involving such vesicles, or the like.

Provided is a manufacturing method of particles coated with coatable microparticles. The method is a manufacturing method of particles coated with coatable microparticles, comprising the step of adding the coatable microparticles to an inner core comprising a component of interest and a macromolecule, and, while rolling the mixture, coating the mixture while spraying a solvent that can dissolve the macromolecule, wherein the particles coated with the coatable microparticles are coated, component of interest-containing hollow particles.

Provided herein are oral pharmaceutical compositions comprising amantadine, or a pharmaceutically acceptable salt thereof, and a pharmaceutically acceptable excipient, and which have a low level of organic solvent. Provided are also methods of orally administrating a composition comprising amantadine, or a pharmaceutically acceptable salt thereof, to a subject, which has reduced gastrointestinal side effects or sleep disturbances. Further provided are extended release oral compositions comprising amantadine, or a pharmaceutically acceptable salt thereof, that are suitable for once daily administration.

A kit for electrocatalytically treating a target tissue is provided, the kit comprising: substantially iron oxide free iron-doped titanium dioxide nanoparticles; a voltage generator; and at least one electrode pair consisting of an anode and a cathode, the electrode pair for electrical communication with the voltage generator. A use of the kit is also provided.

The pharmacokinetic profile of the SGLT2 inhibitor bexagliflozin can be improved by formulating it as an extended release tablet. Compared with standard immediate-release dosage forms these tablets can permit a lower peak plasma concentration, C.sub.max, while maintaining plasma concentrations at therapeutic levels for a desired period. This can be used, for instance, to administer lower doses while still providing the same pharmacological effect.

A population of capsules, the capsules can include a core including a benefit agent and a shell surrounding the core, wherein the shell can include a first shell component.

A composition including metallic silver nanoparticles is supported on a carrier, wherein the carrier is in the form of particles. The carrier is selected from an inert carrier or an antibiotic. The composition further includes at least one antibiotic in the case the carrier is an inert carrier. A related nanosystem includes a composition having metallic silver nanoparticles or a mixture of silver nanoparticles and at least one antibiotic for use in the treatment of an infection caused by at least one strain of bacteria resistant to at least one antibiotic. Pharmaceutical compositions and methods for the preparation of these compositions and nanosystems are also used for the treatment of bacterial infections.

Described are sustained-release solid dosage forms of epigallocatechin gallate (EGCG) or aminosterol compositions. In one aspect of the invention the sustained-release solid dosage forms of EGCG or an aminosterol are capsules comprising a plurality of coated solid particulates. Another aspect of the invention relates to methods of inhibiting, ameliorating, reducing the likelihood of, delaying the onset of, treating or preventing an amyloid disorder, comprising the step of administering to a subject in need a therapeutically effective amount of the solid dosage form. In certain aspects, the amyloid disorder is Parkinson's Disease.

There is provided a production method for a microcapsule in which cells are encapsulated with alginic acid and a polycation, the method including dropwise adding a cell suspension containing cells and alginic acid into a calcium ion-containing solution to obtain a liquid droplet in which the cells are encapsulated in alginic acid, and immersing the liquid droplet in a coating liquid containing a polycation, to obtain the microcapsule, where the coating liquid contains a calcium ion or a barium ion at a concentration of 0.1 mM or more and 50.0 mM or less. According to the production method of the present invention, it is possible to produce a microcapsule having a uniform shape and particle size.
