  • Patent number: 7563773
    Abstract: This invention provides for, inter alia, oral homogeneous veterinary pastes for the treating, controlling and preventing of endo- and ectoparasite infections in warm-blooded animals or birds, such as horses and household pets. This invention further provides for a process of preparing these veterinary pastes and for a method for increasing the bioavailability of the anthelmintic agents contained in the paste in the warm-blooded animal or bird. The inventive oral homogeneous anthelmintic pastes comprise a first anthelmintic agent, for example, prazequantel and/or pyrantel, and at least one marcrolide anthelmintic compound, a solvent, which dissolves both the first anthelmintic agent and second the macrolide anthelmintic compound, and a thickening agent.

  • Publication number: 20080145317
    Abstract: The invention relates to an effervescent formulation containing florfenicol or an antibiotic of related structure. When introduced into water, the effervescent formulation is dissolved with minimal or no agitation and provides a solution or a homogeneous dispersion of florfenicol. The formulations are typically in the form of free flowing powders, granules or tablets. The effervescent formulations are useful for the treatment of bacterial infections and allow for the rapid dispersion and dissolution of florfenicol in the drinking water systems of an animal in need of such treatment.

  • Publication number: 20050136087
    Abstract: The invention relates to a stabilized premix feed or feed-like formulation that has an extended shelf life due to a decrease of the degradates of the active ingredient by controlling the amount of an already existing stabilizer in the formulation. The feed premix is used in the treatment or prophylaxis of parasites in mammals, in particular swine and horses. The invention further relates to a method to extend the shelf life of a stable premix feed or feed-like formulation for the treatment or prophylaxis of parasite infestation in swine and horses comprising controlling the amount of an already existing antioxidant or stabilizer in the formulation to decrease or to prevent the formation of acid/base catalyzed decomposition of the active ingredient.
