A novel dosage form for intra-oral delivery of nicotine for use in nicotine replacement therapy; a process for preparation of said dosage form and intermediate compositions therefor; and methods for treatment.

An oral methylphenidate extended release tablet is described, which can be scored and still retain its extended release profile. The tablet contains a combination of an uncoated methylphenidate-ion exchange resin complex, a barrier coated methylphenidate-ion exchange resin complex-matrix, and an uncomplexed methylphenidate active component. Following administration of a single dose of the extended release methylphenidate chewable tablet, a therapeutically effective amount of methylphenidate is reached in less than about 20 minutes and the composition provides a twelve-hour extended release profile.

An aqueous liquid suspension containing a coated drug-ion exchange resin complex comprising a core composed of an amphetamine complexed with a pharmaceutically acceptable ion-exchange resin and an uncoated amphetamine-ion exchange resin complex is provided. The coated amphetamine-ion exchange resin complex is in admixture with a polymer to form a matrix. Methods of making the coated complex and the liquid suspension are described.

An oral pharmaceutical composition is provided that can comprise a rho kinase inhibitor, for example, fasudil, a pharmaceutically acceptable salt thereof, a hydrate thereof, a prodrug thereof, a substituted derivative thereof, or a metabolite thereof, or any combination thereof, the rho kinase inhibitor having a bitter taste; and an ion exchange resin. The ion exchange resin can partially or fully mask the bitter taste of the rho kinase inhibitor, making the composition more palatable. The composition can comprise a solid dosage form, and/or a liquid dosage form. The solid dosage form can comprise a powder, granules, a tablet, or a capsule, or any combination thereof. The composition can be present, for example, in a unit dose, in an amount sufficient to treat a neurodegenerative disease. A method of treating the neurodegenerative disease with the oral pharmaceutical composition is provided. The method can ameliorate a symptom of a neurodegenerative disease.

Disclosed are the cation polymers capable of removing their positive charges in oxidative conditions, preparation methods, and applications as gene delivery carriers. The oxidation-responsive unit is the p-(boronic acid or ester)benzylammonium, which upon oxidation eliminates p-hydroxymethlphenol and thus converts in a tertiary amine. Compared with the prior art, different from a common quaternary amination carrier, the synthesized charge reversal type gene delivery carrier for oxidative response of the present invention has a large quantity of positive charges and can well coat a DNA, but the positive charges can be removed under the condition of intracellular oxidation when the charge reversal type gene delivery carrier enters a cell, a charge reverse is triggered, the positive charges turn to negative charges, and the DNA is quickly released for transfection. The carrier is efficient, low in toxicity, and good in application prospect.

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.

Methods, compositions, reagents, and systems that allow for the preparation and utilization of sulfonamide salt polymer electrolytes are disclosed herein. Methods and reagents to prepare sulfonamide salt monomers are also disclosed herein. The sulfonamide salt polymer electrolytes can be used as components in energy storage devices, conductive materials, electrochemical cells, gels, adhesives, and drug delivery vehicles.

A process for the preparation of an erodible tamper-resistant dosage form that comprises a therapeutic agent-substrate complex embedded in a thermo-formable matrix, such that the complex includes at least one therapeutic agent bound to at least one substrate to form the therapeutic agent-substrate complex. The at least one substrate is being selected from a polyelectrolyte, an organic counter-ion, a pharmacologically inert organic component of a prodrug, an inclusion compound and an inorganic adsorbent; and the thermo-formable matrix includes one or more thermoplastic polymers and optionally at least one pharmaceutical additive. The dosage form provides resistance to intentional or unintentional tampering such as chewing, crushing and grinding, and volatilization.

Provided herein are materials for the promotion of tissue regeneration, and methods of promoting tissue regeneration and wound healing therewith. In particular, materials displaying laminin-derived peptide sequences that facilitate cell migration into the material, and methods of use thereof, are provided.
