Pemoline Health Article

Definition

Pemoline is classified as a central nervous system (CNS) stimulant. It is sold in the United States under the brand names Cylert and PemADD and is also available under its generic name.

Purpose

Pemoline is used in combination with psychological, educational, and social support for the treatment of attention-deficit/hyperactivity disorder (ADHD).

Description

Pemoline is a central nervous system stimulant that derives at least some of its effects by increasing levels of dopamine in the brain. Dopamine is one of several neurotransmitters in the brain. Neurotransmitters are naturally occurring chemicals that regulate the transmission of nerve impulses from one cell to another. Mental and physical well-being are partially dependent on maintaining the proper balance among the various neurotransmitters in the brain.

Pemoline is similar in its effects to dextroamphetamine and methylphenidate, two other drugs used to treat ADHD, although it is not chemically related to these drugs. The mechanism of action of CNS stimulants in the treatment of ADHD is not totally clear, but probably includes increased mental alertness, decreased mental fatigue, and an increased sense of well-being.

Pemoline should not be used as a substitute for psychological, educational, and social support in treating ADHD. Because pemoline may be associated with liver toxicity (poisoning causing liver damage), it should be used only after other drugs to treat ADHD have been tried. Patients should try dextroamphetamine or methylphenidate first.

Pemoline is available in 18.75-mg, 37.5-mg, and 75-mg oral tablets and in 37.5-mg chewable tablets.

Recommended dosage

The dose of pemoline should be carefully adjusted to patient need. The initial dose of pemoline in children six years of age or older is 37.5 mg each morning. The dose may be increased by 18.75 mg each week to as much as 75 mg daily. Most people respond to doses ranging from 56.25 mg to 75 mg daily, although some people may require as much as 112.5 mg daily.

There is no need to continue pemoline indefinitely. Rather, patients should be evaluated both during therapy and during periods in which the medication is voluntarily stopped. In many situations, the drug may be safely discontinued altogether when the child reaches adolescence.
