Pharmaceutical compositions for prevention of overdose or abuse
The invention relates to pharmaceutical compositions comprised of a chemical moiety attached to an active agent in a manner that substantially decreases the potential of the active agent to cause overdose or to be abused. When delivered at the proper dosage the pharmaceutical composition provides therapeutic activity similar to that of the parent active agent.
1. A method of treating attention deficit hyperactivity disorder in a patient in need thereof, comprising orally administering an effective amount of an amphetamine (1-phenylpropan-2-amine) covalently bound to a chemical moiety, wherein the chemical moiety is a naturally occurring, non-standard amino acid, the amino acid is bound through its C-terminus to the amino group of the amphetamine, and the bound amphetamine maintains a steady-state serum release curve which provides a therapeutically effective bioavailability of the amphetamine.
2. The method of claim 1 , wherein the naturally occurring, non-standard amino acid is homoserine.
3. The method of claim 1 , wherein the naturally occurring, non-standard amino acid is ornithine.
4. The method of claim 1 , wherein the naturally occurring, non-standard amino acid is sarcosine.
5. The method of claim 1 , wherein the amphetamine is dextroamphetamine.
6. A method of treating attention deficit hyperactivity disorder in a patient in need thereof, comprising orally administering an effective amount of an amphetamine (1-phenylpropan-2-amine) covalently bound to a chemical moiety, wherein the chemical moiety is a naturally occurring, non-standard amino acid and the amino acid is bound through its C-terminus to the amino group of the amphetamine, wherein the bound amphetamine is administered in an oral dosage form.
7. The method of claim 6 , wherein the amphetamine is dextroamphetamine.
8. The method of claim 6 , wherein the oral dosage form comprises from 5 to 500 mg of the bound amphetamine.
9. The method of claim 6 , wherein the patient is administered an oral dosage form of the bound amphetamine once daily.
10. The method of claim 7 , wherein the oral dosage form comprises from 5 to 500 mg of the bound amphetamine.
11. The method of claim 7 , wherein the patient is administered an oral dosage form of the bound amphetamine once daily.
