Calcium hydroxide nanoparticles (Ca(OH).sub.2NPs) synthesized using carob pulp extract may be hexagonal nanoparticles with a diameter ranging from about 31.22 nm to about 81.22 nm. The Ca(OH).sub.2NPs may be synthesized by heating ethylene glycol, adding calcium hydroxide to the ethylene glycol to provide a first mixture, heating the first mixture, adding a carob pulp aqueous extract to the first mixture to form a second mixture, heating the second mixture, adding sodium hydroxide (NaOH) to the second mixture to form a third mixture, heating the third mixture, resting the third mixture at room temperature after heating, centrifuging the third mixture, collecting a colloid sediment, extracting any unwanted contaminants from the colloid sediment, and drying the colloid sediment to obtain Ca(OH).sub.2NPs.

The present invention discloses an extended release multi-particulate sprinkle composition comprising a plurality of discrete units, each discrete unit comprising quetiapine or a pharmaceutically acceptable salt thereof and one or more pharmaceutically acceptable excipients.

The disclosure provides pharmaceutical formulations of the compound of Formula I:

##STR00001##

or a pharmaceutically acceptable salt thereof.

A composition in powder form comprising alginic acid or sodium alginate, -pectin and chitosan, wherein the % by weight of the polysaccharides is at least 20% with respect to the total weight of the powder, the process for preparing the powder and its use in the treatment of cutaneous wounds and in the sector of food preservation are described.

The present disclosure concerns a composition for an implantable pharmaceutical composition prepared from components consisting only of calcium sulfate α-hemihydrate in combination with two antibiotics, vancomycin and gentamicin, for the treatment of infection in bone and soft tissue.

A dry granulation process using a twin-screw extruder for granulating a powder mixture which includes at least one active ingredient and at least one carrier. The process includes steps of kneading the powder mixture in the screw barrel of the twin-screw extruder at a barrel temperature below a melting point of the at least one active ingredient and a melting point or a glass transition temperature of the at least one carrier to provide a kneaded powder mixture, and extruding the kneaded powder mixture to form granules. Granules and tablets produced using the dry granulation process in the twin-screw extruder are also provided.

The present disclosure provides for spherical microbeads, methods of making, and methods of use. The spherical microbeads can be tailored to deliver one or more agents over a desired time frame (e.g., short burst or extended-release or combinations thereof). For example, spherical microbeads can be used for the extended-release of oxygen. The spherical microbeads are amendable for an injectable approach and/or ease of integration within cellular implants due in part to their spherical dimensions and size.

A method for preparing a microsphere include steps of dissolving an active ingredient and a biodegradable polymer in an organic solvent to prepare a dispersed phase, dissolving a salt in water to prepare a continuous phase, mixing and stirring the dispersed phase and the continuous phase to form an emulsion, removing the organic solvent; and drying.

The present invention provides a method for manufacturing a dispersion in which a substance, which is poorly soluble in a dispersion medium, is dispersed with a particle size of a nano-order level. More particularly, the method includes: preparing a solution containing a good solvent and the poorly soluble substance and the surfactant dissolved in the good solvent; rapidly cooling the solution to a temperature at which the poorly soluble substance precipitates in the solution at a temperature lowering rate of 100 to 4,000° C./second to produce ultrafine particles with a particle size of a nano-order level formed of the poorly soluble substance in the good solvent; and (i) separating the good solvent from a mixed solution of the solution and the dispersion medium after mixing the solution and the dispersion medium, or (ii) mixing the dispersion medium to the solution after separating the good solvent from the solution.

Multiparticulate compositions including an active agent and a gelling agent are disclosed. The multiparticulate compositions are prepared by an aqueous-based spray and congeal process.
