Abstract: The present invention provides a parasiticidal formulation comprising: Fipronil, or a veterinarily acceptable derivative thereof; at least one C1-C6 alcohol co-solvent, wherein the total amount of C1-C6 alcohol is up to 8% by weight of the formulation; at least one organic solvent which is not the C1-C6 alcohol co-solvent; and at least one crystallization inhibitor, wherein the total amount of crystallization inhibitor is from 2 to 20% by weight of the formulation. The formulations of the invention have higher flash points than known parasiticidal formulations comprising Fipronil and therefore provide safer formulations for use in the home, storage, manufacture and distribution.

Abstract: Fipronil co-formulations are provided herein. The formulations comprise an organic solvent, an alcohol co-solvent, and one or more antioxidants. The formulations provided herein are antiparasitic, and can be used, for example, to combat dog and cat parasites, such as, fleas and ticks.

Abstract: Fipronil formulations and fipronil/S-methoprene co-formulations are provided herein. These formulations optionally contain one or more additional active ingredient(s). The formulations comprise an organic solvent, an alcohol co-solvent, and one or more antioxidants and without any crystallization inhibitor. The formulations provided herein are antiparasitic, and can be used, for example, to combat dog and cat parasites, such as, fleas and ticks.

Abstract: An apparatus includes a medicament container and a package. The medicament container includes a wall configured to define a medicament reservoir. The wall includes a protrusion configured to propagate a deformation of the wall when an external force is applied to the protrusion to reduce a volume of the medicament reservoir. The package includes a blister portion and a foil portion and defines a cavity therebetween. The blister portion is configured to cover the medicament reservoir when the medicament container is disposed within the cavity.

Abstract: An apparatus includes a substrate and a wall coupled to the substrate. The substrate and the wall define a medicament reservoir. At least a portion of the wall is configured to be deformed to reduce a volume of the medicament reservoir when the wall is actuated. The wall includes an actuation portion, which can be used to actuate the wall. The portion of the wall is configured to deform at a first rate when the actuation portion is in a first configuration, and a second rate when the actuation portion is in a second configuration.
