Introduction: What is Dextroamphetamine?

Dextroamphetamine is a prescription medication primarily used to treat attention deficit hyperactivity disorder (ADHD) and narcolepsy. It belongs to a class of drugs known as stimulants, which work by affecting certain chemicals in the brain that contribute to hyperactivity and impulse control. Dextroamphetamine is a more potent form of amphetamine and is recognized for its effectiveness in improving focus, attention, and overall cognitive function in individuals diagnosed with ADHD.

Uses of Dextroamphetamine

Dextroamphetamine is approved for several medical uses, including:

• Trastorno por déficit de atención con hiperactividad (TDAH): It helps increase attention and decrease impulsiveness and hyperactivity in patients with ADHD.
• Narcolepsia: Dextroamphetamine is used to treat narcolepsy, a sleep disorder characterized by excessive daytime sleepiness and sudden sleep attacks.
• Obesidad: In some cases, it may be prescribed as a short-term treatment for obesity, although this is uncommon due to its abuse potential.

Cómo funciona

Dextroamphetamine works by increasing the levels of certain chemicals (neurotransmitters) in the brain, particularly dopamine and norepinephrine. These chemicals play a crucial role in regulating mood, attention, and behavior. By enhancing the activity of these neurotransmitters, dextroamphetamine helps improve focus, attention span, and impulse control, making it easier for individuals with ADHD to manage their symptoms.

Dosificación y administración

The dosage of dextroamphetamine varies based on the condition being treated, the patient's age, and their response to the medication.

• Adults with ADHD: The typical starting dose is 5 mg once or twice daily, which may be increased by 5 mg weekly. The maximum recommended dose is usually 40 mg per day.
• Niños (6 años y mayores): The starting dose is often 2.5 mg once or twice daily, with gradual increases as needed. The maximum dose for children is generally 30 mg per day.
• Narcolepsia: Adults may start with 10 mg per day, with adjustments made based on individual response.

Dextroamphetamine is available in various forms, including immediate-release tablets, extended-release capsules, and oral solutions. It is typically taken once or twice daily, with or without food.
