Description

Pemoline belongs to the group of medicines called central nervous system (CNS) stimulants. It is used to treat children with attention-deficit hyperactivity disorder (ADHD).

Pharmacology

Pemoline has a pharmacological activity similar to that of other known central nervous system stimulants; however, it has minimal sympathomimetic effects. Although studies indicate that pemoline may act in animals through dopaminergic mechanisms, the exact mechanism and site of action of the drug in man is not known.

Peak serum levels of the drug occur within 2 to 4 hours after ingestion of a single dose. Multiple dose studies in adults at several dose levels indicate that steady state is reached in approximately 2 to 3 days.

Pemoline has a gradual onset of action. Using the recommended schedule of dosage titration, significant clinical benefit may not be evident until the third or fourth week of drug administration.

Indications and Usage

Pemoline is indicated in Attention Deficit Disorder (ADD) with hyperactivity as an integral part of a total treatment program which typically includes other remedial measures (psychological, educational, social) for a stabilizing effect in children with a behavioral syndrome characterized by the following group of developmentally inappropriate symptoms: moderate to severe distractibility, short attention span, hyperactivity, emotional lability, and impulsivity. The diagnosis of this syndrome should not be made with finality when these symptoms are only of comparatively recent origin. Nonlocalizing (soft) neurological signs, learning disability, and abnormal EEG may or may not be present, and a diagnosis of central nervous system dysfunction may or may not be warranted.

Contraindications

Pemoline is contraindicated in patients with known hypersensitivity or idiosyncrasy to the drug. Pemoline should not be administered to patients with impaired hepatic function.

Warnings

Suppression of growth (height/weight) has been reported with the long-term use of stimulants in children. Therefore, patients requiring long-term therapy should be carefully monitored. Some doctors recommend drug-free periods during treatment with pemoline.

Pemoline is not recommended for children less than 6 years since its safety and efficacy in this age group have not been established.

Precautions

Clinical experience suggests that in psychotic children, administration of pemoline may exacerbate symptoms of behavior disturbance and thought disorder.

Pemoline should be administered with caution to patients with significantly impaired renal function.

Liver function tests should be performed prior to and periodically during therapy with pemoline.

Long-term effects of pemoline in children have not been established.

CNS stimulants, including pemoline, have been reported to precipitate motor and phonic tics and Tourette's syndrome. Therefore, clinical evaluation for tics and Tourette's syndrome in children and their families should precede use of stimulant medications.

Drug treatment is not indicated in all cases of ADD with hyperactivity and should be considered only in light of complete history and evaluation of the child. The decision to prescribe pemoline (pemoline) should depend on the physician's assessment of the chronicity and severity of the child's symptoms and their appropriateness for his/her age. Prescription should not depend solely on the presence of one or more of the behavioral characteristics.

Pregnancy and Withdrawl: Safety for use during pregnancy and nursing has not been established. Although CNS stimulants are seldom indicated after puberty, it should be kept in mind that pemoline should not be used during pregnancy or in women who may become pregnant.

Interference with Cognitive or Motor Performance: Using this medicine alone, with other medicines, or with alcohol may lessen your ability to drive or to perform other potentially dangerous tasks. Do not drive, operate machinery, or do anything else that could be dangerous until you know how you react to this medicine.

Drug Interactions

Decreased seizure threshold has been reported in patients receiving pemoline concomitantly with antiepileptic medications.

BEFORE USING THIS MEDICINE: INFORM YOUR DOCTOR OR PHARMACIST of all prescription and over-the-counter medicine that you are taking. Inform your doctor of any other medical conditions including liver conditions, allergies, pregnancy, or breast-feeding.

Adverse Reactions

CHECK WITH YOUR DOCTOR AS SOON AS POSSIBLE IF YOU EXPERIENCE yellowing of the skin or eyes, dark urine or pale stools, or unusual tiredness.

Common side effects include: difficulty sleeping or drowsiness, dizziness, headache, nausea, stomach pain, or loss of appetite.

Physical/Psychological Dependence:

The pharmacologic similarity of pemoline to other psychostimulants with known dependence liability suggests that psychological and/or physical dependence might also occur with pemoline. There have been isolated reports of transient psychotic symptoms occurring in adults following the long-term misuse of excessive oral doses of pemoline. Pemoline should be given with caution to emotionally unstable patients who may increase the dosage on their own initiative.

After you stop using this medicine, your body may need time to adjust. The length of time this takes depends on the amount of medicine you were using and how long you used it. During this period of time check with your doctor if you notice any of the following side effects: Abdominal pain; convulsions (seizures); headache; mental depression; nausea; unusual behavior; unusual tiredness or weakness; vomiting.

Symptoms of overdose may include vomiting, tremors, muscle twitching, convulsions, hallucinations, confusion, sweating, headache, and rapid pulse.
