20150060581 | Production of Near Monodisperse Particles using Milling and Membrane Separation - The present invention provides a method for producing particles having a reduced particle size distribution, which method comprises the steps of: a) providing a composition comprising particles; b) subjecting the particles in said composition to a size reduction step or to a size growth step; c) feeding said particles to a first membrane separation system to separate said particles according to size; d) recycling those particles that do not meet the size criteria back to step a); e) optionally, collecting in a collection tank the permeate of the first membrane separation system. Particles obtainable according to the method of the invention and characterized by having a near monodisperse particle size distribution are also provided. The particles are preferably characterized by having a particle size distribution with a span of less than 2.0. The invention also provides pharmaceutical compositions comprising particles according to the invention, and also apparatus for carrying out the method of the invention. | 03-05-2015 |
20140147504 | TETRACYCLINE TOPICAL FORMULATIONS, PREPARATION AND USES THEREOF - The invention relates to a topical suspension formulation that includes a tetracycline, a liquid medium and a polymeric gelling agent. The tetracycline may be in the form of its pharmaceutically acceptable salts, hydrates, or polymorphs and is in a suspended form within the formulation. The liquid medium is selected such that it does not dissolve or substantially minimally dissolves the tetracycline. The gelling agent is a polymeric hydrocarbon gelling agent. Preferably, the tetracycline has a particle size of less than or equal to about 20 microns. | 05-29-2014 |
20110259328 | SIMPLE CAPSULE-BASED INHALER - A dry powder inhaler for pulmonary or nasal use, employing capsules containing a dose of powder for inhalation, comprising two operating components and an optional cover. Air is drawn by the patient via a mouthpiece or nosepiece which is in communication with the capsule and travels via air paths through the device and through the capsule thereby dispersing and entraining the dose of powder. The capsule is cut by cutting means located on one of the components, in a manner which eliminates or minimizes capsule debris and minimizes powder leakage during use. The inhaler body and capsule cutting blades comprise a single operating component and they may be manufactured in a single unitary step. The invention affords a very economical and simple device for the delivery of pulmonary medicines. | 10-27-2011 |
