System and method for deactivation and disposal of a pharmaceutical dosage form
View Patent ↗A system and method are provided for deactivation and disposal of a pharmaceutical dosage form. The system and method employ an oxidant and an immobilizing agent placed in a container. The pharmaceutical dosage form is placed into the container, and water is added to the container. A rapid chemical deactivation of the active ingredient or ingredients in the pharmaceutical then occurs by a chemical oxidation process. Upon contact with the water, the immobilizing agent swells or expands in volume to form a gel or slurry, binding the other components in the container within the gel or slurry, where they remain after disposal. The system can be in the form of a kit, or can be scaled up for use by municipalities or institutions.
1. A system for disposing of a pharmaceutical dosage form, the system comprising:
a container;
an oxidant selected from the group consisting of non-chlorine, stabilized peroxide compounds; stable chlorine-based oxidizing agents; and metal oxides, wherein the oxidant is contained in a first water soluble package;
a transition metal complex of a tetra-amido macrocyclic ligand as activating agent; and
an immobilizing agent;
wherein (i) the activating agent and the immobilizing agent are contained in second and third water soluble packages, or (ii) the activating agent and the immobilizing agent are provided as a mixture in a second water soluble package, or (iii) the activating agent is provided in a second water soluble package and the container comprises the immobilizing agent.
2. The system of claim 1 , wherein the stabilized peroxide compounds are selected from the group consisting of persulfate, permonosulfate, perborate, percarbonate, permanganate, stable organic peroxo compounds, and salts thereof.
3. The system of claim 1 , wherein the oxidant comprises magnesium oxide or calcium oxide.
4. The system of claim 1 , wherein the oxidant comprises one or more metal oxides in the form of particles ranging in size from nanometers to micrometers.
5. The system of claim 1 , wherein the immobilizing agent comprises a gelling agent or an encapsulant.
6. The system of claim 5 , wherein the encapsulant comprises one or more swellable clay minerals.
7. The system of claim 5 , wherein the encapsulant comprises montmorillonite or bentonite.
8. The system of claim 7 , wherein the bentonite comprises sodium bentonite.
9. The system of claim 1 , wherein the immobilizing agent comprises activated carbon.
10. The system of claim 1 , wherein the container includes a closure.
11. The system of claim 1 , wherein the container comprises a waterproof material.
12. The system of claim 1 , wherein the transition metal is Fe.
