  • Patent number: 7399488
    Abstract: An abuse-deterrent pharmaceutical composition has been developed to reduce the likelihood of improper administration of drugs, especially drugs such as opiods. In the preferred embodiment, a drug is modified to increase its lipophilicity. In preferred embodiments the modified drug is homogeneously dispersed within microparticles composed of a material that is either slowly soluble or not soluble in water. In some embodiments the drug containing microparticles or drug particles are coated with one or more coating layers, where at least one coating is water insoluble and preferably organic solvent insoluble, but enzymatically degradable by enzymes present in the human gastrointestinal tract. The abuse-deterrent composition retards the release of drug, even if the physical integrity of the formulation is compromised (for example, by chopping with a blade or crushing) and the resulting material is placed in water, snorted, or swallowed.

  • Patent number: 7217427
    Abstract: The present invention provides biocompatible vesicles comprising semi-permeable, thin-walled encapsulating membranes which are formed in an aqueous solution, and which comprise one or more synthetic super-amphiphilic molecules. When at least one super-amphiphile molecule is a block copolymer, the resulting synthetic vesicle is termed a “polymersome.” The synthetic, reactive nature of the amphiphilic composition enables extensive, covalent cross-linking of the membrane, while maintaining semi-permeability. Cross-linking of the polymer building-block components provides mechanical control and long-term stability to the vesicle, thereby also providing a means of controlling the encapsulation or release of materials from the vesicle by modifying the composition of the membrane. Thus, the encapsulating membranes of the present invention are particularly suited for the reliable, durable and controlled transport, delivery and storage of materials.

  • Patent number: 7160557
    Abstract: A lipid or other hydrophobic or amphiphilic compound (collectively referred to herein as “hydrophobic compounds”) is integrated into a polymeric matrix for drug delivery to alter drug release kinetics. In embodiments where the drug is water soluble, the drug is released over longer periods of time as compared to release from the polymeric matrix not incorporating the hydrophobic compound into the polymeric material. In contrast to methods in which a surfactant or lipid is added as an excipient, the hydrophobic compound is actually integrated into the polymeric matrix, thereby modifying the diffusion of water into the microparticle and diffusion of solubilized drug out of the matrix. The integrated hydrophobic compound also prolongs degradation of hydrolytically unstable polymers forming the matrix, further delaying release of encapsulated drug.

    Abstract: A method of preparing an excipient composition includes forming an aqueous slurry containing a mixture of microcrystalline cellulose in the form of a wet cake and a surfactant, said surfactant being present in an amount from about 0.1% to about 0.5% by weight of the wet-cake microcrystalline cellulose; and drying said slurry to obtain an excipient comprising a plurality of agglomerated particles of microcrystalline cellulose in intimate association with said surfactant. The excipient may be mixed with a therapeutically active agent to form a dosage form. The surfactant provides a hydrophobic boundary at cellulose surfaces, and improves absorptivity of the therapeutically active agent.

  • Patent number: 6936274
    Abstract: This invention provides a storage-stable dosage form of a thyroxine active drug composition which exhibits an improved stability. The formulation contains a thyroxine active drug substance, an alditol, and a saccharide, and, optionally, additional pharmaceutically accepted excipients. Levothyroxine sodium is the preferred active drug substance, mannitol is the preferred alditol, and sucrose is the preferred saccharide. Additional preferred excipients include, for example, microcrystalline cellulose, crospovidone, magnesium stearate, colloidal silicon dioxide, and sodium lauryl sulfate.

  • Patent number: 6921541
    Abstract: A formulation and methods for inducing sustained regional local anesthesia in a patient comprising a substrate comprising a local anesthetic and an effective amount of a biocompatible, biodegradable, controlled release material prolonging the release of the local anesthetic from the substrate to obtain a reversible local anesthesia when implanted or injected in a patient, and a pharmaceutically acceptable, i.e., non-toxic, non-glucocorticoid augmenting agent effective to prolong the duration of the local anesthesia for a time period longer than that obtainable from the substrate without the augmenting agent.

  • Patent number: 6919074
    Abstract: Cosmetic, dermatological and pharmaceutical compositions containing quaternary ammonium compounds, particularly for hair-treatment, require low setting points, good solubility and dispersibility in aqueous media and a low flash point. It has now been found that such compositions can be formulated with quaternary ammonium compounds essentially free of short-chain alcohols such as isopropanol. The novel composition comprises: a) at least one quaternary ammonium compound and b) at least one branched alcohol having 8 to 36 carbon atoms or a mixture of at least one branched alcohol and at least one unbranched alcohol having 8 to 36 carbon atoms.

  • Patent number: 6835394
    Abstract: The present invention provides biocompatible vesicles comprising semi-permeable, thin-walled encapsulating membranes which are formed in an aqueous solution, and which comprise one or more synthetic super-amphiphilic molecules. When at least one super-amphiphile molecule is a block copolymer, the resulting synthetic vesicle is termed a “polymersome.” The synthetic, reactive nature of the amphiphilic composition enables extensive, covalent cross-linking of the membrane, while maintaining semi-permeability. Cross-linking of the polymer building-block components provides mechanical control and long-term stability to the vesicle, thereby also providing a means of controlling the encapsulation or release of materials from the vesicle by modifying the composition of the membrane. Thus, the encapsulating membranes of the present invention are particularly suited for the reliable, durable and controlled transport, delivery and storage of materials.
