摘要： The present specification describes a medicated device adapted for a single, acute, and rate-controlled rectal or vaginal administration to a mammal of a lipophilic prostaglandin. The device accomplishes drug administration at an essentially time-independent rate of dosage. Further, the device advantageously results in the substantial exhaustion of the prostaglandin from the device at the conclusion of the single, acute use. The device comprises three elements:(A) an inert resilient support means contoured for easy vaginal or rectal insertion;(B) a first flexible polymer film layer affixed to the support means and containing the prostaglandin dispersed therethrough, this first polymer film not being rate limiting as to the release of drug from the device; and(C) a second polymer film, laminated onto the first polymer film and providing a release rate therefrom of prostaglandin, which is rate limiting both as to the release of prostaglandin from the device and absorption rate by the rectal or vaginal tissues.

摘要： The present specification describes a medicated device adapted for a single and rate-controlled rectal or vaginal administration to a mammal of a systemically active pharmaceutical (SAP). The device accomplishes drug administration at an essentially time-independent rate of dosage. Further, the device advantageously results in the substantial exhaustion of the SAP from the device at the conclusion of the single, acute use. The device comprises three elements:(A) an inert resilient support means contoured for easy vaginal or rectal insertion;(B) a first flexible polymer film layer affixed to the support means and containing the SAP dispersed therethrough, this first polymer film not being rate limiting as to the release of drug from the device; and(C) a second polymer film, laminated onto the first polymer film and providing a release rate therefrom of prostaglandin, which is rate limiting both as to the release of prostaglandin from the device and absorption rate by the rectal or vaginal tissues.

摘要： Methods for the management of bronchopulmonary insufficiency and other conditions are disclosed. The methods involve administration of an N-7-substituted derivative of theophylline selected from the group consisting of dyphylline, etophylline, proxyphylline and mixtures thereof. The derivative can be administered intravenously, intramuscularly, or in the lungs, concurrently with some form of theophylline or administered alone to a patient whose body has a known or an unknown theophylline content. Theophylline and the derivative can be administered in the same dosage form or in separate dosage forms. They can have the same route of administration or different routes of administration; for example, theophylline can be given orally, while the derivative is given as a zero-order intravenous infusion. A high total plasma concentration of methyl xanthine is achieved safely by using a combination of theophylline and one or more of the derivatives. Rapid injection of a loading dose of the derivative is also disclosed.

摘要： The present invention is drawn to methods of preparing a bioactive agent-containing emulsion for delivery to a biological system. This method can comprise the step of jetting a bioactive agent and a first fluid medium from a fluid-jet pen into a second fluid medium to form a bioactive agent-containing emulsion, wherein the second fluid comprises a continuous phase of the emulsion. Alternatively, a method of preparing a bioactive agent-containing liposome can comprise jetting a lipid-containing composition and a bioactive agent from a fluid-jet pen into a medium to form a bioactive agent-containing liposome carried by the medium. The present invention is also drawn to fluid-jet pens and systems configured for making liposome- and emulsion-containing biological agents.

摘要： Active agents comprising coated pellets which self seal if they are damaged are described. More specifically, an active agent, or bead coated with an active agent, is coated with a rate-release controlling polymer and a hydrophilic gel-forming material which forms a gel upon hydration. If the bead is compressed into a solid compact which damages the polymer coating, the hydrophilic substance gels upon exposure to an aqueous environment. The gel provides sufficient sealing of the damaged area in the polymer so that a useful control of drug release is retained in spite of the damage to the polymer. The pellets of the invention exhibit improved flow and compactability. The compacts can be formulated to disintegrate in the gastrointestinal tract, and also may result in either controlled release or immediate release of the active agent.

摘要： An improved powdered bacterial growth medium composition adapted to be admixed with water is described. The powdered growth medium includes an alkaline earth metal cation in a compound A admixed with a compound B containing an anion which reacts with the alkaline earth metal cation in compound A in an aqueous growth medium to form an essentially water insoluble salt or base, including the alkaline earth metal cation and the anion, which is acid neutralizing. The water insoluble salt is thus formed in situ in the aqueous growth medium when compounds A and B are added to the aqueous solution. Also described is an improved method for growing acid producing bacteria in an aqueous growth medium by forming the insoluble salt or base. The resulting growth medium is particularly adapted for neutralizing acids generated during growth of lactic acid producing bacteria which are grown for use in various food fermentations.

摘要： An expanding tablet is described comprising a drug release controlling membrane material. After swallowing, the tablet hydrates and expands such that the membrane ruptures to directly expose some surfaces of the core tablet to hydrating and eroding liquids, thus generating in situ a tablet which is platform supported on non-exposed surfaces, and which releases active ingredient in approximately zero order fashion. More particularly, the dosage form is adapted for controlled release of various pharmaceuticals. A working embodiment of the tablet was a spray-coated tablet comprising a core having greater than 25% of an expandable material which expands upon exposure to an aqueous environment and at least one active ingredient, e.g., glipizide, and an outer rupturable coating surrounding the core comprising a rate release modifying membrane and a water-soluble modifier. A method for administering an active ingredient also is described. The method comprises (1) providing a tablet according to the invention, and (2) administering the tablet to a patient.

摘要： A process for treating radioactive contaminated soils to remove radioactive metal oxide contaminants therefrom comprises creating a suspension of particles of the soil in a column of water, alternately forcing fresh water in the column upwardly to force ligher soil particles upwardly in the column and allowing heavier particles to gravitationally settle in the bottom of the water column. The heavy particles comprising radioactive metal oxides are collected and handled for radioactive waste material storage. The aqueous slurry of lighter soil particles is directed to a separator for removing substantial amounts of water after which the particles are directed to a conveyor and spread out to a substantially uniform thickness and detected for any radioactivity. Portions of material in which radioactive particles are detected ar diverted and the uncontaminated soil material is recovered.
