Levoamfetamiini

Levoamfetamiini is the levorotatory enantiomer of amfetamine. It is a sympathomimetic amine that acts as a central nervous system stimulant. Chemically, it is (S)-1-phenylpropan-2-amine. While amfetamine exists as two stereoisomers, dextroamphetamine and levoamphetamine, levoamphetamine has a weaker effect on the central nervous system compared to dextroamphetamine. It primarily exerts its effects through the release of dopamine and norepinephrine from presynaptic terminals. Levoamphetamine has a greater affinity for peripheral adrenergic receptors, leading to more pronounced peripheral effects such as increased heart rate and blood pressure. It is often found as a component in certain pharmaceutical preparations, although its use is less common than that of dextroamphetamine or racemic amfetamine. Due to its stimulant properties, it has potential for abuse and is a controlled substance in many countries. Its pharmacological profile differs significantly from its dextrorotatory counterpart, with levoamphetamine being less effective for treating conditions like ADHD.
