5 results about "Chagas disease" patented technology

The presently disclosed subject matter provides a method and pharmaceutical composition for long-term use in treating or preventing disease conditions caused by the parasite Trypanosoma cruzi known as Chagas disease. The pharmaceutical composition is a long-term injectable composition that can include a dose of Itraconazole and a dose of Amiodarone in an amount effective to treat Chagas disease, or in an amount effective to prevent Chagas disease in a human or animal patient such as a mammal. The pharmaceutical composition may also include a pharmaceutically acceptable vehicle, carrier, or excipient. The form of itraconazole used in the pharmaceutical composition may be prepared by any suitable process wherein the active ingredients to have sufficient bioavailability when injected into a human or animal subject. The long-term method for treating or preventing Chagas disease is carried out by a single injection of Itraconazole and Amiodarone in an amount effective to treat a subject in need thereof, and / or in an amount effective to prevent the subject from contracting the disease so that repeated dosages are not required again for a long-term period such as 6 or 12 months. The present compositions, methods, and uses are safer and longer lasting, more patient friendly, and provide a safer and more effective way of treating or preventing Chagas disease than previously possible.

Diagnostic methods, systems, test strips, test kits, and other immunoassay materials are provided for the detection of antibodies to one or more specific parasites of veterinary and human concern in biological samples, including those that are responsible for Chagas disease (Trypanosoma cruzi), Leishmaniasis (Leishmania infantum), and Heartworm (Dirofilaria immitis).
