ABSTRACT:
A method for administering a pharmaceutical to an animal includes imbibing a plurality of carriers with the pharmaceutical, placing a barrier into the animal, defining a first zone and a second zone within the animal, the barrier permitting passage of the pharmaceutical between the zones and impeding passage of the carriers between the zones, and placing the imbibed carriers into the first zone. Also, a method for treating mastitis in a mammal includes imbibing a plurality of carriers with an antibiotic effective in combating a mastitis-causing pathogen, placing a barrier into the udder of the mammal, defining a first zone and a second zone within the udder, the barrier permitting passage of the pharmaceutical and impeding passage of the carriers, and placing the imbibed carriers into the first zone. Also, apparatus for administering a pharmaceutical to an animal includes a barrier adapted to permit passage of the pharmaceutical and to resist passage of carriers adapted to reversibly hold the pharmaceutical, the barrier being positionable within the animal such that the barrier may define a first zone and a second zone within the animal, and a plurality of such carriers positionable within the first zone, whereby as the pharmaceutical is released from the carriers it may pass the barrier from the first zone into the second zone.
