The formulation has excellent flowability even at relatively high contents of fine particles. | 05-10-2012 |
| 20120027863 | Pharmaceutical Compositions for Inhalation - The invention provides microparticles for use in a pharmaceutical composition for Pulmonary administration, each microparticle comprising a particle of an active substance having, on its surface, particles of a hydrophobic material suitable for delaying the dissolution of the active substance. The invention also provides a method for making the microparticles. | 02-02-2012 |
| 20110236492 | DRY POWDER INHALER FORMULATIONS COMPRISING SURFACE-MODIFIED PARTICLES WITH ANTI-ADHERENT ADDITIVES - The present invention is concerned with a refinement of the processing of particles that are to form a dry powder formulation which is to be administered to the lung using a dry powder inhaler (DPI) device. In particular, the present invention provides the processing of particles of active material and particles of carrier material in the presence of additive material to provide a powder composition which exhibits excellent powder properties and which is economical to produce. | 09-29-2011 |
| 20110217339 | MUCOACTIVE AGENTS FOR TREATING A PULMONARY DISEASE - The present invention relates to pharmaceutical compositions which are useful in the treatment of diseases where excess mucus is present in the respiratory tract, such as cystic fibrosis and chronic obstructive pulmonary disease. In particular, the invention relates to pharmaceutical compositions for administration by pulmonary inhalation. | 09-08-2011 |
| 20110182997 | SUSPENSION FORMULATIONS - The present invention relates to suspension formulations, especially those for delivering a pharmaceutically active agent in aerosol form using a spray or aerosol device, such as a pressurised metered dose inhaler (pMDI). The formulations may be for pulmonary, nasal, buccal or topical administration, but are preferably for pulmonary inhalation. | 07-28-2011 |
| 20110077272 | PULMONARY FORMULATIONS OF TRIPTANS - A pharmaceutical composition includes triptans, such as sumatriptan, and may be used in therapy. The composition may be administered via the inhaled route. | 03-31-2011 |
| 20100330188 | CARRIER PARTICLES FOR USE IN DRY POWDER INHALERS - A powder for use in a dry powder inhaler includes active particles and carrier particles for carrying the active particles. The powder further includes additive material on the surfaces of the carrier particles to promote the release of the active particles from the carrier particles on actuation of the inhaler. The powder is such that the active particles are not liable to be released from the carrier particles before actuation of the inhaler. The inclusion of additive material in the powder has been found to give an increased respirable fraction of the active material. | 12-30-2010 |
| 20100285142 | Method Of Making Particles For Use In A Pharmaceutical Composition - A method for making composite excipient particles for use in a pharmaceutical composition comprises a milling step in which particles of an excipient material are milled in the presence of an additive material. The product particles are of small size and the milling requires relatively low input of time and energy. The composite particles are suitable for use in inhalable pharmaceutical compositions. | 11-11-2010 |
| 20100258118 | INHALER DEVICES AND BESPOKE PHARMACEUTICAL COMPOSITIONS - The present invention relates to inhaler devices and bespoke pharmaceutical dry powder composition to be dispensed using such inhaler devices for pulmonary administration. In particular, the present invention relates to the provision of passive inhaler devices and dry powder compositions which are specifically formulated and prepared to be efficiently dispensed by such devices to reproducibly achieve a high delivered dose of the pharmaceutically active agent. | 10-14-2010 |
| 20100209358 | Method of Making Particles For Use In A Pharmaceutical Composition - The invention relates to a method for making composite active particles for use in a pharmaceutical composition for pulmonary administration, the method comprising a milling step in which particles of active material are milled in the presence of particles of an additive material which is suitable for the promotion of the dispersal of the composite active particles upon actuation of an inhaler. The invention also relates to compositions for inhalation prepared by the method. | 08-19-2010 |
| 20100015234 | Pharmaceutical preparations and their manufacture - A method for making a composition comprising active particles comprising an active substance comprises the steps of a) providing an emulsion having a dispersed phase comprising a solution of the active substance in a solvent and b) inducing the formation, in the emulsion, of solid particles comprising the active substance. The particles may be isolated from the emulsion. Active particles having a normalized kurtosis of at least 5 and a mean diameter of less than 100 μm are provided. | 01-21-2010 |
| 20090269412 | Pharmaceutical formulations for dry powder inhalers - A powder for use in a dry powder inhaler comprises: i) a fraction of fine particle size constituted by a mixture of physiologically acceptable excipient and an additive; ii) a fraction of coarse particles; and iii) at least one active ingredient. The powder is suitable for efficacious delivery of active ingredients into the low respiratory tract of patients suffering from pulmonary diseases such as asthma. In particular, the invention provides a formulation to be administered as dry powder for inhalation which is freely flowable, can be produced in a simple way, is physically and chemically stable and capable of delivering accurate doses and/or high fine particle fraction of low strength active ingredients by using a high- or medium resistance device. | 10-29-2009 |
| 20080220078 | Pharmaceutical Formulations - A pharmaceutical formulation for delivery in aerosol or spray form, comprising a liquefied propellant gas, a solid particulate pharmaceutically active agent and a dispersing agent, wherein the dispersing agent is fused to the surface of particles of the pharmaceutically active agent. | 09-11-2008 |
