Patent number: 7279457Abstract: Drug formulations for systemic drug delivery with improved stability and rapid onset of action are described herein. The formulations may be administered via buccal administration, sublingual administration, pulmonary delivery, nasal administration, subcutaneous administration, rectal administration, vaginal administration, or ocular administration. In the preferred embodiments, the formulations are administered sublingually or via subcutaneous injection. The formulations contain an active agent and one or more excipients, selected to increase the rate of dissolution. In the preferred embodiment, the drug is insulin, and the excipients include a metal chelator such as EDTA and an acid such as citric acid. Following administration, these formulations are rapidly absorbed by the oral mucosa when administered sublingually and are rapidly absorbed into the blood stream when administered by subcutaneous injection. In one embodiment, the composition is in the form of a dry powder.Type: GrantFiled: March 11, 2005Date of Patent: October 9, 2007Assignee: Biodel, Inc.Inventors: Roderike Pohl, Solomon S. Steiner

Patent number: RE40493Abstract: Paclitaxel is provided in a porous matrix form, which allows the drug to be formulated without Cremophor and administered as a bolus. The paclitaxel matrices preferably are made using a process that includes (i) dissolving paclitaxel in a volatile solvent to form a paclitaxel solution, (ii) combining at least one pore forming agent with the paclitaxel solution to form an emulsion, suspension, or second solution, and (iii) removing the volatile solvent and pore forming agent from the emulsion, suspension, or second solution to yield the porous matrix of paclitaxel. The pore forming agent can be either a volatile liquid that is immiscible with the paclitaxel solvent or a volatile solid compound, preferably a volatile salt. In a preferred embodiment, spray drying is used to remove the solvents and the pore forming agent.Type: GrantFiled: August 26, 2005Date of Patent: September 9, 2008Assignee: Acusphere, Inc.Inventors: Julie A.
