A microcapsule suspension for treating a protein-containing surface includes droplets of a dispersed water-immiscible core phase, an aqueous continuous phase, and a wall surrounding each core phase droplet. The wall includes the salt formed from at least one Lewis base reactant and at least one Lewis acid reactant, wherein at least one Lewis base reactant or Lewis acid reactant is amphiphilic and wherein at least one Lewis acid reactant is selected from the group consisting of proteins, protein hydrolysates, charged amino acids, and water-soluble salts of any of these.

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.

Pharmaceutical preparations and methods for treating or preventing a heart failure disease, including heart failure with preserved ejection fraction (HFPEF), with one or more dialkyl fumarates alone or in combination with one or more second agents are provided herein. In some embodiments, the pharmaceutical preparations are in the form of micro-tablets or pellets.

The present invention relates in part to a 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 multiparticulate sprinkle dosage forms.

A tablet for the controlled release of a drug. The tablet is in the form of an asymmetrically coated tablet so that immediate release or time-delayed release times can be precisely controlled and the extended release slab may provide zero-order or first-order extended release and pulsatile release depending on the excipients used in the tablet formulations. The core of the tablet is coated with an asymmetrical coating, that is, a coating with regions having different properties. The coatings may include drugs in varying concentrations. Further, different regions of the coating may have different rates of dissolution. The core of the tablet may be provided with a constant cross-sectional area along a longitudinal length of the tablet, a coating having a first region with a more rapid rate of dissolution than a second region. The dissolution of the first region exposes only the cross-sectional area to the dissolution medium. The second region of the coating prevents any other portion of the core of the tablet from being exposed to the dissolution medium. Therefore, since the cross-sectional area remains constant as it is dissolved, the rate of release of the drug from the core of the tablet remains constant. The cross-sectional area may be of any geometrical configuration so long as the area remains constant as the core dissolves.

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.

The present invention relates, in part, to a composition comprising a multicationic drug and an organic multianion. In some embodiments, the multicationic drug is enclosed within a carrier. In some embodiments, the carrier is a liposome. In some embodiments, the multicationic drug and organic multianion are enclosed within a carrier, while in other embodiments, the multicationic drug is enclosed within the carrier and the organic multianion is outside the carrier. The present invention also relates, in part, to a method of treating a subject for pulmonary distress comprising administering to a subject in need thereof the aforementioned composition.

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.

Pharmaceutical compositions and stable nano-suspensions comprising mifepristone and at least one pharmaceutically acceptable excipient, which exhibit enhanced bioavailability compared to the currently marketed or commercially available formulations. Manufacturing process and methods of use are also provided. The pharmaceutical compositions are used for prevention, treatment or prophylaxis of disorders in human patients in need thereof. Oral pharmaceutical compositions of mifepristone, methods for their administration, processes for their production, and use of these compositions are described for the treatment of diseases for which mifepristone is indicated.
