    摘要: The present invention generally relates to systems and methods for delivering and/or withdrawing a substance or substances such as blood or interstitial fluid, from subjects, e.g., from the skin and/or from beneath the skin. In one aspect, the present invention is generally directed to devices and methods for withdrawing or extracting blood from a subject, e.g., from the skin and/or from beneath the skin, using devices containing a fluid transporter (for example, one or more microneedles), and a storage chamber having an internal pressure less than atmospheric pressure prior to receiving blood. In some cases, the device may be self-contained, and in certain instances, the device can be applied to the skin, and activated to withdraw blood from the subject. The device, or a portion thereof, may then be processed to determine the blood and/or an analyte within the blood, alone or with an external apparatus.

    摘要: Clinical studies have been conducted and specific dosage formulations developed using polymeric microparticles having incorporated therein perfluorocarbon gases that provide significantly enhanced images of long duration. The dosage formulation includes microparticles formed of a biocompatible polymer, preferably including a lipid incorporated therein, and containing a perfluorocarbon that is a gas at body temperature. The microparticles are provided to a patient in an amount effective to enhance ultrasound imaging in the ventricular chambers for more than 5 minutes or in the mycocardium for more than a minute, in a dose ranging from 0.025 to 8.0 mg microparticles/kg body weight. Preferably the dose ranges from 0.05 to 4.0 mg microparticles/kg body weight. The dosage formulation typically is provided in a vial. A typical formulation is in the form of a dry powder that is reconstituted with sterile water prior to use by adding the water to the vial or syringe of the dry powder and shaking to yield an isosmotic or isotonic suspension of microparticles.

    摘要: 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.

    摘要: Methods are provided for making a dry powder blend pharmaceutical formulation comprising (i) forming microparticles which comprise a pharmaceutical agent; (ii) providing at least one excipient in the form of particles having a volume average diameter that is greater than the volume average diameter of the microparticles; (iii) blending the microparticles with the excipient to form a powder blend; and (iv) jet milling the powder blend to deagglomerate at least a portion of any of the microparticles which have agglomerated, while substantially maintaining the size and morphology of the individual microparticles. Jet milling advantageously can eliminate the need for more complicated wet deagglomeration processes, can lower residual moisture and solvent levels in the microparticles (which leads to better stability and handling properties for dry powder formulations), and can improve wettability, suspendability, and content uniformity of dry powder blend formulations.

    摘要: Methods and apparatus are provided for making particles comprising: (a) spraying an emulsion, solution, or suspension, which comprises a solvent and a bulk material (e.g., a pharmaceutical agent), through an atomizer and into a primary drying chamber, having a drying gas flowing therethrough, to form droplets comprising the solvent and bulk material dispersed in the drying gas; (b) evaporating, in the primary drying chamber, at least a portion of the solvent into the drying gas to solidify the droplets and form particles dispersed in drying gas; and (c) flowing the particles and at least a portion of the drying gas through a jet mill to deagglomerate or grind the particles. By coupling spray drying with “in-line” jet milling, a single step process is created from two separate unit operations, and an additional collection step is advantageously eliminated. The one-step, in-line process has further advantages in time and cost of processing.
