Abstract

Methods for treating Attention Deficit Disorder, Attention Deficit Hyperactivity Disorder, AIDS Dementia Complex and cognitive decline in HIV-AIDS while minimizing drug hypersensitivity, toxicity, side effects, euphoric effect, and drug abuse potential by administration of d-threo-methylphenidate or pharmaceutically acceptable salts thereof.

Claims

1. A method of treating Attention Deficit Hyperactivity Disorder comprising administrating on a daily basis to a human having Attention Deficit Hyperactivity Disorder, 5 to 50 mg of D-threo methylphenidate, or a pharmaceutically acceptable salt thereof, substantially free of L-threo methylphenidate, wherein the D-threo methylphenidate, or pharmaceutically acceptable salt, is mixed with a pharmaceutically acceptable carrier, diluent, or excipient.

2. The method according to claim 1 wherein the amount of D-threo methylphenidate administered is 5 mg per day.

3. The method according to claim 1 wherein the amount of said D-threo methylphenidate, or a pharmaceutically equivalent salt thereof, is greater than 90% of the total amount of methylphenidate.

5. The method according to claim 1 wherein the amount of D-threo methylphenidate enhances therapeutic activity compared to racemic methylphenidate.

6. The method according to claim 1 wherein the administration is one to four times per day.

7. The method according to claim 1 wherein the amount of D-threo methylphenidate administered is 20 mg per day.

8. The method according to claim 1 wherein the amount of D-threo methylphenidate administered is 50 mg per day.

4. The method according to claim 4 wherein the amount of said D-threo methylphenidate, or a pharmaceutically equivalent salt thereof, is greater than 99% of the total amount of methylphenidate.
