Abstract

The pharmaceutical kit may comprise a specified amount of individual doses in a package. Each individual dose in the package may contain a pharmaceutically effective amount of a conjugate of d-threo methylphenidate.

First claim

We claim:

1. A method of treating stimulant abuse and addiction wherein the method comprises administering, to a human or animal subject in need thereof, a composition comprising a compound, wherein the compound is a conjugate of d-methylphenidate having the following chemical formula:

salts thereof,
or mixtures thereof.

2. The method of claim 1 , wherein the stimulant is cocaine or methamphetamine.

3. The method of claim 1 , wherein the salt the compound is at least one pharmaceutically or therapeutically acceptable salt form or salt mixture thereof.

4. The method of claim 3 , wherein the at least one pharmaceutically or therapeutically acceptable salt form is independently selected from the group consisting of acetate, l-aspartate, besylate, bicarbonate, carbonate, d-camsylate, l-camsylate, citrate, edisylate, formate, fumarate, gluconate, hydrobromide/bromide, hydrochloride/chloride, d-lactate, l-lactate, d,l-lactate, d,l-malate, l-malate, mesylate, pamoate, phosphate, succinate, sulfate, bisulfate, d-tartrate, martrate, d,l-tartrate, meso-tartrate, benzoate, gluceptate, d-glucuronate, hybenzate, isethionate, malonate, methylsulfate, 2-napsylate, nicotinate, nitrate, orotate, stearate, tosylate, thiocyanate, acefyllinate, aceturate, aminosalicylate, ascorbate, borate, butyrate, camphorate, camphocarbonate, decanoate, hexanoate, cholate, cypionate, dichloroacetate, edentate, ethyl sulfate, furate, fusidate, galactarate, galacturonate, gallate, gentisate, glutamate, glutarate, glycerophosphate, heptanoate, hydroxybenzoate, hippurate, phenylpropionate, iodide, xinafoate, lactobionate, laurate, maleate, mandelate, methanesulfonate, myristate, napadisilate, oleate, oxalate, palmitate, picrate, pivalate, propionate, pyrophosphate, salicylate, salicylsulfate, sulfosalicylate, tannate, terephthalate, thiosalicylate, tribrophenate, valerate, valproate, adipate, 4-acetamidobenzoate, camsylate, octanoate, estolate, esylate, glycolate, thiocyanate, and undecylenate.

5. The method of claim 3 , wherein the at least one pharmaceutically or therapeutically acceptable salt form of the compound is independently selected from the group consisting of chloride, hydrochloride, hydrogen carbonate (bicarbonate), iodide, bromide, citrate, acetate, formate, salicylate, hydrogen sulfate (bisulfate), hydroxide, nitrate, hydrogen sulfite (bisulfite), propionate, benzene sulfonate, hypophosphite, phosphate, bromate, iodate, chlorate, fluoride, and nitrite.

6. The method of claim 1 , wherein the composition is in a dosage form selected from the group consisting of a sublingual, a gummy, a chewable tablet, a rapidly dissolving tablet, a tablet, a capsule, a caplet, a troche, a lozenge, an oral powder, a solution, a thin strip, an oral thin film (OTF), an oral strip, a rectal film, a syrup, a suspension, and a suppository.

7. The method of claim 6 , wherein the dosage form is administered orally.

8. The method of claim 1 , wherein the composition has a dosing regimen that is selected from the group consisting of about four times a day or less, about three times a day or less, about two times a day or less, and about one time a day.

9. The method of claim 8 , wherein the composition has a dosing regimen that is about one time a day.

10. The method of claim 1 , wherein the composition provides a dose amount that is the molar equivalent to a dose from about 0.1 mg to about 500 mg d-methylphenidate hydrochloride per dose.

11. The method of claim 1 , wherein the composition is provided in a unit dose form, blister pack, roll, or bulk bottle.

12. The method of claim 11 , wherein the unit dose form provides an amount of d-methylphenidate that is molar equivalent to about 0.5 mg to about 500 mg d-methylphenidate hydrochloride.

13. The method of claim 1 , wherein the composition further comprises one or more excipients or one or more additional pharmaceutically active ingredients.

14. The method of claim 13 , wherein the excipients are selected from the group consisting of antiadherents, binders, coatings, disintegrants, gel forming agents, fillers, flavors and colors, glidants, lubricants, preservatives, sorbents and sweeteners.
