Patent number: 6730322Abstract: 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.Type: GrantFiled: March 6, 2003Date of Patent: May 4, 2004Assignee: Acusphere, Inc.Inventors: Howard Bernstein, Donald Chickering, Sarwat Khattak, Julie Straub

Patent number: 6696071Abstract: An aqueous douche or enema is disclosed, containing a water-soluble zinc salt at an anti-viral concentration, designed for use shortly before and/or shortly after intercourse. Unlike a lubricant for use during intercourse, this type of rinsing liquid will not contain glycerine or similar lubricating components, and will be designed to not leave behind a film-type residue. However, this type of “pericoital” rinse (i.e., intended for pre-coital or post-coital use) will leave behind positively-charged zinc ions. Due to electrostatic attraction, these Zn++ ions will cling to negatively-charged canyons and other “binding sites” in proteins that are exposed and accessible on the surfaces of cells and virus particles. The binding of Zn++ ions to negatively-charged sites in these surface proteins will alter and disrupt the ability of viruses (including herpes and HIV) to bind to and infect human cells.Type: GrantFiled: November 27, 2001Date of Patent: February 24, 2004Inventor: Patrick D. Kelly

Patent number: 6555126Abstract: This invention pertains to a method that can control, treat, and prevent Diabetes Mellitus. The method includes means of administering a potent product, including mainly the active ingredient Linalool, in any one of several forms, alone or with other additives and catalysts, such as vitamin E to enable the body to handle and control, then correct the complications of Diabetes Mellitus. A modest percentage of users suffering from this disease can be cured completely while the majority of others improve remarkably and experience lower blood glucose and reduce the glycated hemoglobin HbAlc readings to what are medically acceptable and healthy levels. Others, who are vulnerable to the disease due to hereditary factors, or other reasons, can help prevent it. The method works in several ways, including activation of the pancreas and re-establishing the ability of body cells to utilize and handle better and well, the glucose in the blood, and regulate the level of natural insulin in the body.Type: GrantFiled: January 2, 2001Date of Patent: April 29, 2003Assignee: Diabex, Inc.Inventors: Osama Mansour Murad, Husni Abu Seir, Hafez Taji Farouqi
