Dextroamfetamin

Dextroamphetamine is a central nervous system stimulant medication. It is a stereoisomer of amphetamine, meaning it has the same chemical formula but a different spatial arrangement of atoms. This difference in structure leads to distinct pharmacological properties, with dextroamphetamine generally considered to be more potent and less prone to causing certain side effects compared to its levoamphetamine counterpart.

The primary mechanism of action for dextroamphetamine involves increasing the levels of neurotransmitters in the brain, particularly dopamine and norepinephrine. It achieves this by blocking the reuptake of these neurotransmitters into the presynaptic neurons and promoting their release. This increase in neurotransmitter activity is thought to be responsible for its stimulant effects, including improved focus, alertness, and reduced fatigue.

Dextroamphetamine is primarily prescribed for the treatment of attention deficit hyperactivity disorder (ADHD) in both children and adults. By enhancing neurotransmitter activity in brain regions associated with attention and impulse control, it can help individuals with ADHD to better manage their symptoms. It is also used in the short-term treatment of narcolepsy, a neurological disorder characterized by excessive daytime sleepiness.

Due to its stimulant properties and potential for abuse, dextroamphetamine is a controlled substance in many countries. Its use is typically supervised by a healthcare professional, and it is available in various formulations, including immediate-release and extended-release tablets and capsules. Common side effects can include loss of appetite, insomnia, dry mouth, and increased heart rate.
