This invention relates to methods of treating various orofacial diseases involving inflammation, infection and / or pain, using intratissue controlled release drug delivery systems. More particularly, the invention relates to methods for localized or targeted administration of a sustained release formulation of an agent such as an anti-inflammatory agent to a specified tissue location within the orofacial environment.

An intraluminal medical device comprises a stent having a coating applied to at least part of an interior surface, an exterior surface, or both. The coating comprises a sustained release formulation of a combination of pharmaceutical compounds dispersed within a biologically tolerated polymer composition. The choice of the combination of pharmaceutical compounds are intended to reduce neointimal hyperplasia restenosis.

A sustained-release oral dosage form of naltrexone or a pharmaceutically acceptable salt thereof is provided. The oral dosage form may be administered with another compound. Administration of the oral dosage form may reduce a side effect, which may be a side effect at least partially attributable to a weight-loss treatment. The oral dosage form may be administered to treat a weight-loss condition.

The present invention provides composition, methods, and articles of manufacture for treating an eye disorder, e.g., a disorder characterized by macular degeneration, choroidal neovascularization, or retinal neovascularization. One method of the invention comprises the step of: administering first and second therapeutic agents to the subject's eye in a single procedure, wherein the first therapeutic agent provides rapid improvement in the condition of the subject's eye and the second therapeutic agent is administered as a sustained release formulation of the second therapeutic agent. For example, the first and second therapeutic agents are administered by intravitreal injection. The first therapeutic agent may be dissolved in a liquid medium located in the syringe and the sustained formulation of the second therapeutic agent may comprise an ocular implant or plurality of particles located in the needle. The therapeutic agents may be selected from the group consisting of angiogenesis inhibitors and complement inhibitors.

A composition comprises a protein, a polyol, and a metal. The protein is stabilized by the polyol and the metal, and is protected from denaturing when in contact with an organic solvent. The polyol may be a hydrocarbon containing two or more hydroxyl groups (—OH) bonded to carbon. The metal may be divalent.

Provided herein in some embodiments is a formulation comprising (a) one or more nanoscale particle; and (b) a film-forming polymer. In some instances, the formulation is an immediate and sustained released formulation suitable for topical administration or administration to surfaces. Also provided here in certain embodiments is a method of reducing the population of pathogenic microorganisms on skin or surfaces, the method comprising applying to the skin or surface a composition, the composition comprising (a) one or more nanoscale particle; and (b) a film-forming polymer.

A sustained release formulation for opioid drugs is described. The formulation contains an opioid-ion exchange resin complex having a hybrid coating. The hybrid coating contains a cured polyvinylacetate polymer and a pH-dependent enteric coating layer mixed therein. Also provided are methods of making and using same.

Systems and methods are described for treating un-met medical needs in migraine and related conditions such as cluster headache. Included are treatments that are both rapid onset and long acting, which include sustained release formulations, and combination products. Also included are treatments for multiple symptoms of migraine, especially headache and nausea and vomiting. Systems that are self contained, portable, prefilled, and simple to self administer at the onset of a migraine attack are disclosed, and preferably include a needle-free injector and a high viscosity formulation, to eliminate such issues as fear of self administration with needles, and needle stick and cross contamination.

Particles are provided for use in therapeutic and / or diagnostic procedures. The particles include poly[bis(trifluoroethoxy) phosphazene] and / or a derivatives thereof which may be present throughout the particles or within an outer coating of the particles. The particles can also include a core having a hydrogel formed from an acrylic-based polymer. Barium sulfate may also be provided to the core of the particles as a coating or absorbed within the core of the particles. The particles can be used to minimize blood flow to mammalian tissues by occluding at least a portion of a blood vessel of the mammal, or to deliver an active agent to a localized area within a body of a mammal by contacting a localized area with at least one of the particles. Further, the particles are useful in sustained release formulations including active agent(s) for oral administration, as tracer particles for injection into the bloodstream of a mammal or for use in enhanced ultrasound imaging. The particles may include agents for increasing density for achieving useful buoyancy levels in suspension.

An oral methylphenidate powder which is reconstitutable into a final oral aqueous sustained release formulation containing at least about 50%, or at least about 80% by weight water based on the total weight of the suspension, is provided. The powder is a blend containing a combination of an uncoated methylphenidate-ion exchange resin complex, a barrier coated methylphenidate-ion exchange resin complex-matrix, and a water soluble buffering agent such that upon formed into an aqueous liquid formulation, the formulation has a pH in the range of about 3.5 to about 5, or about 4 to about 4.5. Following administration of a single dose of the oral aqueous methylphenidate suspension, a therapeutically effective amount of methylphenidate is reached in less than one hour and the composition provides a twelve-hour extended release profile.

The invention relates to a novel pharmaceutical sustained release formulation of guaifenesin and at least one additional drug ingredient. The formulation may comprise a hydrophilic polymer, preferably a hydroxypropyl methylcellulose, and a water-insoluble polymer, preferably an acrylic resin, in a ratio range of about one-to-one (1:1) to about nine-to-one (9:1), more preferably a range of about three-to-two (3:2) to about six-to-one (6:1), and most preferably in a range of about two-to-one (2:1) to about four-to-one (4:1) by weight. This formulation capable of providing therapeutically effective bioavailability of guaifenesin for at least twelve hours after dosing in a human subject. The invention also relates to a modified release product which has two portions: a first portion having an immediate release formulation of guaifenesin and a second portion having a sustained release formulation of guaifenesin, wherein one or both portions has at least one additional drug ingredient. The modified release product has a maximum guaifenesin serum concentration equivalent to that of an immediate release guaifenesin tablet, and is capable of providing therapeutically effective bioavailability of guaifenesin for at least twelve hours after dosing in a human subject.

The present invention provides an improved process for the preparation of a agglomerated solid dosage form, comprising: (1) preparing an aqueous slurry of (a) microcrystalline cellulose; (b) a microcrystalline cellulose compressibility augmenting agent which (i) physically restricts the proximity of the interface between adjacent cellulose surfaces; (ii) inhibits interactions between adjacent cellulose surfaces, for example, via the creation of a hydrophobic boundary at cellulose surfaces; or (iii) accomplishes both (i) and (ii) above; and (c) an active agent; (2) thereafter drying the resultant aqueous slurry in a manner which inhibits quasi-hornification, thereby obtaining an agglomerated material which is directly compressible into a solid dosage form.
