FIG. 2 illustrates an environment 200 that includes the animal 198, a cross-sectional view of an example final dosage form 202 for delivering the medicament 190 to the animal, and the example stimulation source 194 operable to emit the stimulus 192. In an embodiment, the final dosage form includes a dosage form having completed a manufacturing or production process. In an embodiment, the final dosage form includes a product, finished tablet, or capsule ready for distribution to a hospital, pharmacy, or retail store for individualizing to a particular animal, such as the animal 198. In an embodiment, the final dosage form may include a tablet shape, a spherical shape, or an ellipsoidal shape. In an embodiment, the final dosage form may include a structure or a particle carryable or transportable by a liquid or other fluid carrier.

The final dosage form 202 includes an outer layer 210, the release element 230, and the chamber 220 as expressed by the chamber wall 222. The release element is configured in a first medicament-release state and modifiable to a second medicament-release state upon an ex vivo exposure to a stimulus. For example, the stimulus may include the stimulus 192. The chamber includes a chamber wall 222, is at least substantially within the outer layer, and is configured to carry the medicament 190. In an embodiment, the final dosage form may include an indicator element 280. In an embodiment, the final dosage form may include a containment element 240.

The environment 200 illustrates an embodiment where the release element 230 encapsulates the medicament 190 in cooperation with the chamber 220 as expressed by the chamber wall 222. The outer layer 210 and the release-element 230 are cooperatively configured to retain the medicament 190 if the release-element is in a first medicament-release state and allow an in vivo discharge of at least a portion of the medicament from the chamber if the release-element is in a second medicament release state. In an embodiment of this example, the release element may include at least one of a poly(vinyl alcohol), gel, gel matrix, hydrogel, and azopolymer photo or light modifiable substance as described above. In an embodiment of this example, the release element may include at least one of a polyanhidride, polyglycolide, polyactide, poly(vinyl acetate), poly(glycolic acid), poly (ethylene), poly(lactic acid), chitosan, or an acoustic or ultrasound modifiable substance as described above. For example, when the first medicament-release state is configured to retard medicament release and the second medicament-release state is configured to allow medicament release in vivo, the release element when configured in the first medicament-release state will retard medicament release from the final dosage form upon delivery of the final dosage form into the animal. For example, in a first medicament release state, the release element is impermeable to the environment outside the final dosage form, and impermeable to the medicament in the chamber. Following exposure to an appropriately configured stimulus, the release element achieves a second medicament release state that is, for example, permeable to the medicament. The second medicament release state may include, for example, a state where the release element dissolves or dissipates upon exposure to an aqueous environment, gastric juices or a certain pH environment.

The operation 892 (not shown) includes dispensing the ex vivo exposed instance of the final dosage form in a package bearing an identifier of the individual animal. For example, the identifier may include a name, or identification number of the animal.

All references are hereby incorporated by reference herein in their entirety to the extent such subject matter is not inconsistent herewith.

In some embodiments, “configured” includes at least one of designed, set up, shaped, implemented, constructed, or adapted for at least one of a particular purpose, application, or function.

It will be understood that, in general, terms used herein, and especially in the appended claims, are generally intended as “open” terms (e.g., the term “including” should be interpreted as “including but not limited to,” the term “having” should be interpreted as “having at least,” the term “includes” should be interpreted as “includes but is not limited to,” etc.). It will be further understood that if a specific number of an introduced claim recitation is intended, such an intent will be explicitly recited in the claim, and in the absence of such recitation no such intent is present. For example, as an aid to understanding, the following appended claims may contain usage of introductory phrases such as “at least one” or “one or more” to introduce claim recitations. However, the use of such phrases should not be construed to imply that the introduction of a claim recitation by the indefinite articles “a” or “an” limits any particular claim containing such introduced claim recitation to inventions containing only one such recitation, even when the same claim includes the introductory phrases “one or more” or “at least one” and indefinite articles such as “a” or “an” (e.g., “a receiver” should typically be interpreted to mean “at least one receiver”); the same holds true for the use of definite articles used to introduce claim recitations. In addition, even if a specific number of an introduced claim recitation is explicitly recited, it will be recognized that such recitation should typically be interpreted to mean at least the recited number (e.g., the bare recitation of “at least two chambers,” or “a plurality of chambers,” without other modifiers, typically means at least two chambers).

Furthermore, in those instances where a phrase such as “at least one of A, B, and C,” “at least one of A, B, or C,” or “an [item] selected from the group consisting of A, B, and C,” is used, in general such a construction is intended to be disjunctive (e.g., any of these phrases would include but not be limited to systems that have A alone, B alone, C alone, A and B together, A and C together, B and C together, or A, B, and C together, and may further include more than one of A, B, or C, such as A₁, A₂, and C together, A, B₁, B₂, C₁, and C₂together, or B₁and B₂together). It will be further understood that virtually any disjunctive word or phrase presenting two or more alternative terms, whether in the description, claims, or drawings, should be understood to contemplate the possibilities of including one of the terms, either of the terms, or both terms. For example, the phrase “A or B” will be understood to include the possibilities of “A” or “B” or “A and B.”

The herein described aspects depict different components contained within, or connected with, different other components. It is to be understood that such depicted architectures are merely examples, and that in fact many other architectures can be implemented which achieve the same functionality. In a conceptual sense, any arrangement of components to achieve the same functionality is effectively “associated” such that the desired functionality is achieved. Hence, any two components herein combined to achieve a particular functionality can be seen as “associated with” each other such that the desired functionality is achieved, irrespective of architectures or intermedial components. Likewise, any two components so associated can also be viewed as being “operably connected,” or “operably coupled,” to each other to achieve the desired functionality. Any two components capable of being so associated can also be viewed as being “operably couplable” to each other to achieve the desired functionality. Specific examples of operably couplable include but are not limited to physically mateable or physically interacting components or wirelessly interactable or wirelessly interacting components.

While various aspects and embodiments have been disclosed herein, the various aspects and embodiments are for purposes of illustration and are not intended to be limiting, with the true scope and spirit being indicated by the following claims.
