Publication number: 20140120165Abstract: A new particle morphology of glucocorticosteroids is described. The forms have a particle morphology that is particularly well suited for use in an inhaled corticosteroid drug suspension formulation for delivery from a next generation nebulizer device. Use of the new glucocorticosteroid particles enables enhanced drug delivery efficiency and increased residence time of the delivered drug in the lungs. New methods for producing glucocorticosteroid particles having these specific particle morphologies are also described. The methods provide a simplified, reproducible and scalable particle formation process that can produce glucocorticosteroid particles having a narrow particle size and shape distribution, a low surface energy, a low aspect ratio, uniform particle morphology and a reduced specific surface area.Type: ApplicationFiled: October 2, 2013Publication date: May 1, 2014Applicant: MAP PHARMACEUTICALS, INC.Inventors: Libo Wu, Wiwik Watanabe, Jian Zhang

Publication number: 20070053844Abstract: Conductive formulations containing conductive agents, such as salts, ionic surfactants, or other substances that are in an ionized state or easily ionized in an aqueous or organic solvent environment, and methods of use, have been developed. One or more active agents, such as antivirals, antimicrobials, anti-inflammatories, proteins or peptides, may optionally be included with the formulation. The active agent may be administered with or incorporated into the formulation, or may be administered after the conductive formulation is administered. When applied to mucosal lining fluids, the formulation alters the physical properties such as the surface tension, surface elasticity, and bulk viscosity of the mucosal lining. The formulation is administered in an amount sufficient to alter biophysical properties in the mucosal linings of the body.Type: ApplicationFiled: May 18, 2006Publication date: March 8, 2007Inventors: Wiwik Watanabe, Matthew Thomas, Jeffrey Katstra, Robert Clarke
