A drug that combines the neutral sulfate salts of dextroamphetamine and racemic amphetamine with the dextro isomer of amphetamine saccharate and d,l amphetamine aspartate (Adderall - Richwood Pharmaceutical) has recently been promoted for treatment of children with Attention-Deficit/Hyperactivity Disorder (ADHD). This same mixture of amphetamine salts was previously marketed as Obetrol for treatment of obesity.

Methylphenidate (Ritalin, and others) is now available in a new extended-release formulation (Concerta--Alza) for treatment of attention deficit/hyperactivity disorder (ADHD).

Methylphenidate is now available in a new extended-release formulation (Metadate CD - Celltech) for treatment of attention deficit/hyperactivity disorder (ADHD). The new product, which is a Schedule II controlled substance, is being advertised directly to consumers.

Atomoxetine (Strattera - Lilly) is the first non-stimulant drug to be approved by the FDA for treatment of attention deficit hyperactivity disorder (ADHD). Unlike other drugs approved for use in ADHD, it is not a controlled substance and is approved for use in adults as well as children. Older non-stimulant drugs that have been used to treat ADHD, although not FDA-approved, include the alpha₂-agonist clonidine (Catapres, and others) and the tricyclic antidepressant desipramine (Norpramin, and others) (Medical Letter 1996; 38:109).

Two new extended-release amphetamine products have been approved by the FDA for once-daily treatment of attention-deficit/hyperactivity disorder (ADHD) in patients ≥6 years old: Adzenys XR-ODT (Neos Therapeutics), an orally distintegrating tablet, and Dyanavel XR (Tris Pharma), an oral suspension.

On February 9, 2005, Health Canada suspended the marketing of Adderall XR (Shire), a mixture of amphetamine salts used to treat attention-deficit hyperactivity disorder (ADHD) (Med Lett Drugs Ther 1994; 36:109). The immediate-release form of Adderall was never marketed in Canada. The withdrawal was based on 20 reports internationally of sudden death in patients taking the drug. These deaths, 14 of them in children, were not linked to overdose or abuse. The FDA decided that the number of sudden deaths was no greater than expected among the large number of people taking the drug, but because 5...

The FDA has approved racemic amphetamine sulfate (Evekeo – Arbor) for oral treatment of attention-deficit/hyperactivity disorder (ADHD) in children ≥3 years old. It was also approved for treatment of narcolepsy in patients ≥6 years old and for short-term treatment of obesity in patients ≥12 years old.

Methylphenidate (Ritalin and others), a Schedule II controlled substance in the USA, is a short-acting central-nervous-system stimulant widely used for treatment of children with school performance or behavior problems, or what is now called Attention Deficit-Hyperactivity Disorder, or AD-HD (American Psychiatric Association, Diagnostic and Statistical Manual of Mental Disorders, third ed., revised [DSM-III R], Washington, DC:authors, 1987, p 50). Some studies have estimated that more than 3% of elementary school students are taking methylphenidate, and one parents' group has brought a...

Lisdexamfetamine dimesylate (Vyvanse - Shire), a prodrug in which d-amphetamine is covalently bonded to L-lysine, has been approved by the FDA for treatment of attention-deficit/hyperactivity disorder (ADHD) in children 6-12 years old. It was designed to have less potential than amphetamine itself for abuse, diversion or overdose toxicity. Like methylphenidate and amphetamines, lisdexamfetamine is a Schedule II controlled substance.

The FDA has approved use of gamma hydroxybutyrate (sodium oxybate is the official generic name; Xyrem - Orphan Medical) for oral treatment of cataplexy in patients with narcolepsy. Gamma hydroxybutyrate (GHB), a metabolite of gamma-aminobutyric acid (GABA), is a central-nervous-system depressant marketed in Europe for use in general anesthesia. In recent years it has been notorious for its use in "date-rape" (Medical Letter 2002; 44:21). Xyrem is a Schedule III controlled substance.
