  • Patent number: 6696071
    Abstract: 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.

  • Patent number: 6652874
    Abstract: Formulations have been developed for regional delivery of drugs, for example, into a cavity such as the pelvic region, peritoneal region, or directly on organs of interest. Regional delivery increases comfort and bioavailability of the drug, resulting in rapid and relatively high blood levels in the regions to be treated in the substantial absence of side effects due to the high levels required for efficacy following systemic delivery. In the preferred embodiment, these formulations consist of drug micro or nanoparticles, which may be formed of drug alone or in combination with an excipient or polymeric carrier. The excipient or polymer may be used to manipulate release rates and to increase adhesion to the affected region. The drug formulation can be applied as a dried powder, a liquid suspension or dispersion, or as a topical ointment, creme, lotion, foam or suppository.

  • Patent number: 6537566
    Abstract: The proliferation of uterine fibroid leiomyoma cells is inhibited by certain Fibroid Cell Growth Inhibitor (FGI) agents. The pharmacological doses of these FGI agents in the milieu of uterine fibroid cells can be made high enough to not only inhibit proliferation, but to also causes cell death. Non-invasive or minimally invasive, non-systemic delivery methods are used to deliver the FGI agent to the milieu of the target fibroid leiomyoma cell population, thereby avoiding the disadvantages and side effects of surgical and systemic hormonal therapy interventions in the treatment of uterine fibroids. The FGI agents are substrates that are normally present or are well tolerated in the human body. The efficacy of the FGI agents appears to be related to their ability to moderate the Protein Kinase C and Mitogen Activated Protein Kinase pathways. Specific FGI agents shown to be useful to inhibit growth or proliferation of uterine fibroid cells include: &agr;-tocopherol, &agr;-tocopherol succinate, and troglitazone.

  • Patent number: 6287551
    Abstract: A solution or gel composition containing activated chlorine dioxide and phosphates, such as disodium hydrogen phosphate, sodium dihydrogen phosphate, trisodium phosphate, and sodium monofluorophosphate, is disclosed for treating herpes virus. The preferred concentration ranges are between about 0.005% to about 2.0% chlorine dioxide, and between about 0.02% to about 3.0% of a phosphate compound. The phosphate compound retards escape of chlorine dioxide in the pH range of 6.0 to 7.4, at which pH chlorine dioxide becomes activated and releases sufficient chlorine dioxide to reduce motility and become lethal to the involved micro-organisms.

  • Patent number: 6267985
    Abstract: The present invention relates to pharmaceutical compositions and methods for improved solubilization of triglycerides and improved delivery of therapeutic agents. Compositions of the present invention include a triglyceride and a carrier, where the carrier is formed from a combination of at least two surfactants, at least one of which is hydrophilic. Upon dilution with an aqueous solvent, the composition forms a clear, aqueous dispersion of the triglyceride and surfactants. An optional therapeutic agent can be incorporated into the composition, or can be co-administered with the composition. The invention also provides methods of enhancing triglyceride solubility and methods of treatment with therapeutic agents using these compositions.
