Minimizing agglomeration, aeration, and preserving the coating of pharmaceutical compositions comprising ibuprofen
Provided are pharmaceutical compositions and methods for preparing pharmaceutical compositions comprising Ibuprofen using solventless mixing methods. Excess coating material that is not bound to coated Ibuprofen may be removed by a sieving process. Coating and dosing ratios can also be optimized to minimize the amount of excess unbound coating material. Additionally, the compositions can be formulated to preserve the functional coating of coated Ibuprofen and to minimize aeration of Ibuprofen when mixed into suspension.

Host-guest metal organic framework systems
A method for producing Metal Organic Framework (MOF) having a framework that encapsulates a bio-molecule, the method comprising combining in a solution the bio-molecule and MOF precursors, wherein the bio-molecule promotes formation of the encapsulating framework.
Hollow nanoparticles with hybrid double layers
The present invention discloses the morphology of hollow, double-shelled submicrometer particles generated through a rapid aerosol-based process. The inner shell is an essentially hydrophobic carbon layer of nanoscale dimension (5-20 nm), and the outer shell is a hydrophilic silica layer of approximately 5-40 nm, with the shell thickness being a function of the particle size. The particles are synthesized by exploiting concepts of salt bridging to lock in a surfactant (CTAB) and carbon precursors together with iron species in the interior of a droplet. This deliberate negation of surfactant templating allows a silica shell to form extremely rapidly, sealing in the organic species in the particle interior. Subsequent pyrolysis results in a buildup of internal pressure, forcing carbonaceous species against the silica wall to form an inner shell of carbon. The incorporation of magnetic iron oxide into the shells opens up applications in external stimuli-responsive nanomaterials.
Method of synthesis of silica vesicles and use thereof
The invention relates, in part, to a method of producing silica vesicles including under controlled conditions to thereby heavily influence the morphology and characteristics of the vesicles. The vesicles are shown to be effective as delivery agents for chemical and biological agents. They are also shown to be useful in methods of treatment and as components of an immunogenic composition.

Microspherical sustained-release injection containing escitalopram and method for preparing same
The present invention relates to a biodegradable polymer microsphere-containing sustained-release injection containing escitalopram as an active ingredient, and to a method for manufacturing the same. In the case of escitalopram microspheres, there is a problem of low encapsulation rate, fracture due to weak strength, and initial over-release due to the phase separation of the liquid drug and the polymer inside the microspheres. In order to solve the problem, it is possible to maximize the encapsulation amount and the encapsulation efficiency of the escitalopram adding a hydrophobic solidifying agent to uniformize the non-uniform phase, to overcome the cracking of the microspheres at high loading conditions, and to properly control the initial release and release delay of the microspheres.
PROCESS FOR THE MANUFACTURE OF PHARMACEUTICAL COMPOSITIONS
There is provided a process for the preparation of composition in the form of a plurality of particles having a weight-, number-, and/or volume-based mean diameter that is between amount 10 nm and about 700 μm, which particles comprise: (a) solid cores, preferably comprising a biologically active agent; and (b) two or more sequentially applied, discrete layers, each of which comprises at least one separately applied coating material, and which two or more layers together surround, enclose and/or encapsulate said cores,
which process comprises the sequential steps of: (1) applying an initial layer of at least one coating material to said solid cores by way of a gas phase deposition technique; (2) discharging the coated particles from the gas phase deposition reactor and subjecting the coated particles to agitation to disaggregate particle aggregates formed during step (1) by way of mechanical sieving technique; (3) reintroducing the disaggregated, coated particles from step (2) into the gas phase deposition reactor and applying a further layer of at least one coating material to the reintroduced particles; and (4) optionally repeating steps (2) and (3) one or more times to increase the total thickness of the at least one coating material that enclose(s) said solid core.
The gas phase deposition technique is preferably atomic layer deposition. When the cores comprise biologically active agent, the compositions may provide for the delayed or sustained release of said active agent without a burst effect.
