Abstract

The present invention comprises a safe and effective system for removal of a range of common pharmaceutical compounds. The formulation comprises activated carbon, accompanied by some larger pebble-like material to help break up capsules and tablets upon shaking, in the presence of an acidified liquid medium. Drugs are added to the bottle and the bottle is shaken so that the drugs are dissolved by the liquid solution and are irreversibly adsorbed onto activated carbon, thereby sequestering them from further use.

First claim

What is claimed is:

1 . A system for disposing of a drug, comprising:
an aqueous solution of acetic acid and one or more alcohols selected from the group consisting of methanol, ethanol, n-propanol and isopropanol; activated carbon; and a mechanical dissolution aid; wherein the solution, activated carbon, and mechanical dissolution aid are provided in a container.

2 . The system of claim 1 , wherein the aqueous solution comprises from 5 to 20% acetic acid and 10 to 30% ethanol.

3 . The system of claim 2 , wherein the aqueous solution comprises 12%% acetic acid and 20% ethanol.

4 . The system of claim 1 , wherein the aqueous solution is used in an amount about 50 to 75% the volume of the container.

5 . The system of claim 1 , wherein the activated carbon is used in an amount ranging from 20 to 35 grams per 100 ml solution.

6 . The system of claim 5 , wherein the activated carbon is used in an amount of 25 grams per 100 ml acid solution.

7 . The system of claim 1 , wherein the activated carbon has a surface area ranging from 500 m 2 /g to 1750 m 2 /g.

8 . The system of claim 7 , wherein the activated carbon is selected from the group GAC 8/20, GAC 12/40, GAC 8/30, K-BG, S-51, Norit SX-4 (PAC), and Norit SX-Ultra (PAC).

9 . The system of claim 1 , wherein the container is made from a plastic or other material, chosen based on its ability to contain a certain volume of formula, accommodate a certain amount of active ingredient, its inertness, or its disposability.

10 . The system of claim 1 , wherein the mechanical dissolution aid is a plurality of pebbles.

11 . The system of claim 10 , wherein the pebbles are approximately 0.2-0.7 cm in diameter and irregularly shaped.

12 . The system of claim 10 , wherein the pebbles are added in an amount from one to four times the amount of the activated carbon used.

13 . The system of claim 1 , wherein the capacity of the system to adsorb drug is at least 2.25 g for an 8 oz container.

14 . The system of claim 1 , wherein the chemicals contained within the drug are dissolved by the solution and adsorbed onto the activated carbon, thus rendering them sequestered and inactive.

15 . A method for disposing of a drug, comprising:
providing a system comprising a container containing an aqueous solution of acetic acid and one or more alcohols selected from the group consisting of methanol, ethanol, n-propanol and isopropanol; activated carbon; and a mechanical dissolution aid; and adding the drug to the container; wherein the chemicals contained within the drug are dissolved by the solution and adsorbed onto the activated carbon, thus rendering them sequestered and inactive.

16 . The method of claim 15 , wherein the acid solution comprises from 5 to 20% acetic acid and 10 to 30% ethanol; the acid solution is used in an amount from 50 to 75% the volume of the container; the activated carbon is used in an amount ranging from 10 to 35 grams per 100 ml solution; the activated carbon has a surface area ranging from 500 m 2 /g to 1750 m 2 /g;
the mechanical dissolution aid is a plurality of pebbles.

17 . The method of claim 16 , wherein the acid solution comprises 80% acetic acid (supplied as a 15% aqueous solution) and 20% ethanol.

18 . The method of claim 16 , wherein the activated carbon is used in an amount of 25 grams per 100 ml acid solution.

19 . The method of claim 16 , wherein the pebbles are approximately 0.2-0.7 cm in diameter and irregularly shaped.

20 . The method of claim 16 , wherein the pebbles are added in an amount from one to four times the amount of the activated carbon used
