Disclosed herein is glutathione in conjunction with an isoselenazol or isothiazol derivative, e.g., ebselen or ebsulfur derivative, to treat diabetes, lupus, or other chronic inflammatory disease. The glutathione is preferably provided in a rapid release oral formulation that presents the glutathione for absorption in the first part of the ileum. The isoselenazol or isothiazol derivative is preferably provided in a delayed release formulation to avoid overlapping high enteric concentration. These may be provided within the same unit dosage form.

The presently disclosed subject matter provides solid, oral, extended release, pharmaceutical particulate and multi-particulate dosage forms with abuse deterrent and overdose protection features/characteristics comprising at least one or two populations of particulates. In certain embodiments, the first population of particulates comprises a therapeutically effective amount of at least one opioid embedded in a polymer matrix, a primary functional coat layer (FC 1), a secondary functional coat 2 coat layer (FC 2), and an over coat; wherein FC 1 comprises a nonionic water-insoluble polymer and, optionally, at least one of a cationic polymer, a nonionic water-soluble polymer, and a water-soluble plasticizer; FC 2 comprises a cationic polymer and, optionally, a nonionic water-insoluble polymer; and the over coat comprises a nonionic water-soluble polymer. The second population of particulates comprises an alkaline agent and, optionally, a pH-stabilizing agent. In certain embodiments, the extended release pharmaceutical dosage form contains at least three different populations of multi-particulates. Each population of particulates is designed for a specific function to accomplish the desired combination of abuse deterrence and overdose protection. The presently disclosed subject matter also provides methods related to the solid, oral, extended release, particulate and multi-particulate dosage forms.

The present invention relates in part a to multiparticulate sprinkle dosage form comprising duloxetine or a pharmaceutically acceptable salt thereof, having higher acid resistance as compared to commercially available delayed release formulations. It further relates to various methods of administering the said multiparticulate sprinkle dosage forms.

A contraceptive drug delivery system is provided in the form of a controlled release, bioerodible pellet for subdermal implantation. The pellet is bioerodible, and provides for the sustained release of a contraceptive agent over an extended time period. Bioerosion products are water soluble, bioresorbed, or both, obviating the need for surgical removal of the implant. Methods of using the drug delivery system, including in female contraception, are also provided.

The invention provides a particle composed of a shell and a hollow, wherein the shell contains a medicament and a polymer, and a volume ratio of the hollow relative to the whole particle is 1%-50%. The invention also provides a process for preparation of the hollow particle, which includes a step of granulating a powder mixture containing a medicament and a polymer, while spraying a solvent capable of dissolving the polymer.

Methods for treating or prophylaxis of a Cryptosporidium infection using compositions comprising a structure disclosed herein. Also provided are pharmaceutical compositions and kits for alleviating the symptoms of, for treating, or for preventing the occurrence of Cryptosporidium infection. The kits comprise one or more compounds having a structure disclosed herein, such as in an oral composition, and instructions for use, storage, and the like.

The invention provides a blood substitute product comprising haemoglobin and a self-assembled microparticle having an acid having two or more acid groups and an organic base in a solvent. The particle is of micron scale. The microparticle may be obtained by contacting a bis-acid and organic base in a hydrophilic solvent, wherein the acid is insoluble or sparingly soluble in the hydrophilic solvent and the organic base is soluble in a hydrophilic solvent.

A pharmaceutical formulation for oral administration with a controlled dissolution rate is provided. The formulation contains Tamsulosin hydrochloride-containing sustained-release pellets. The sustained-release pellets include (i) a Tamsulosin hydrochloride, (ii) hydroxypropyl methylcellulose (HPMC), (iii) an acid-resistant acryl polymer, and (iv) two or more kinds of insoluble diluents. A preparation method of the formulation is provided.

This invention is directed to a biodegradable, semi-crystalline, phase separated thermoplastic multi-block copolymer, a process for preparing said multi-block copolymer, a composition for the delivery of at least one biological active compound, and to a method for delivering a biologically active compound to a subject in need thereof. A multi-block copolymer of the invention is characterized in that: a) it comprises at least one hydrolysable pre-polymer (A) segment and at least one hydrolysable pre-polymer (B) segment, b) said multi-block copolymer having a T.sub.g of 37? C. or less and a T.sub.m of 110-250? C. under physiological conditions; c) the segments are linked by a multifunctional chain-extender; d) the segments are randomly distributed over the polymer chain; e) at least part of the pre-polymer (A) segment is derived from a water-soluble polymer.

A particulate, modified release barrier coated drug-cation exchange resin complex comprising a core composed of a drug complexed with a pharmaceutically acceptable ion-exchange resin is provided. Methods of making and products containing this coated complex are described.
