It increases the levels of neurotransmitters like dopamine and norepinephrine in the brain, which helps improve focus, concentration, and control hyperactive behavior. Pemoline has a slower onset of action compared to other stimulants. [2]
Medical Uses of Pemoline
Pemoline was primarily used for treating ADHD symptoms in children and adolescents. It helped reduce restlessness, impulsivity, and improve attention span. Off-label uses of pemoline included treatment of narcolepsy and depression. [3]

Pemoline was available as oral tablets in strengths of 18.75 mg, 37.5 mg, and 75 mg. The recommended starting dose for children was 37.5 mg/day, which could be increased gradually based on response and tolerability. The maximum recommended dose was 112.5 mg/day. [3]
Side Effects and Risks
Common side effects of pemoline included insomnia, anorexia, irritability, and stomach pain. The most serious adverse effect was liver toxicity, which could be fatal in rare cases. Regular liver function monitoring was necessary during pemoline therapy. [4]
Contraindications and Precautions

Patients and caregivers were advised to follow the medication instructions carefully and report any side effects to the healthcare provider. Liver function tests were required before starting pemoline and periodically during treatment. Patients were counseled on the signs and symptoms of liver problems. [3]
Alternatives to Pemoline
After the discontinuation of pemoline, other stimulant medications like methylphenidate and amphetamines became the primary treatments for ADHD. Non-stimulant options like atomoxetine and guanfacine were also used. Non-ph armacological interventions like behavioral therapy and educational support were recommended as adjuncts to medication. [6]
