Liquid Amphetamine Formulations

Introduction to Liquid Formulations

• Liquid formulations represent one of several novel delivery systems developed over the past two decades for stimulant medications, alongside chewable tablets and transdermal patches, designed to improve medication adherence and provide dosing flexibility 1, 2

Clinical Considerations

• Liquid formulations allow for precise dose titration and are particularly useful in pediatric populations or patients who have difficulty swallowing tablets, offering more flexibility with dosing frequency compared to long-acting formulations 1, 2
• Short-acting formulations like liquid dextroamphetamine provide dosing flexibility but may have higher risk of rebound effects compared to long-acting formulations, which are associated with better medication adherence 2
• Common adverse effects remain consistent across formulations, including decreased appetite, sleep disturbances, increased blood pressure and pulse, headaches, irritability, and stomach pain, all generally mild and temporary 1, 2

Amphetamine Formulations and Their Clinical Implications

Medication Dosage and Administration

• The American College of Obstetricians and Gynecologists recommends that Dexedrine is typically dosed starting at 5 mg twice daily for immediate release or 10 mg once daily for Spansule (extended-release) formulations, while Adderall XR is started at 10 mg once daily in the morning 3, 4, 5

Therapeutic Use and Pregnancy Considerations

• The American College of Obstetricians and Gynecologists notes that amphetamines, including both Dexedrine and mixed amphetamine salts like Adderall, generally do not seem to be associated with major congenital malformations 3, 6
