Dextroamphetamine is a central nervous system stimulant used to treat attention deficit hyperactivity disorder (ADHD) and narcolepsy. It works by increasing the levels of certain neurotransmitters in the brain, improving focus, attention, and wakefulness.

Product Description:

Dextroamphetamine is the dextrorotatory isomer of amphetamine, several times more potent centrally than the levo isomer. It enters presynaptic neurons, reverses the dopamine and noradrenaline transporters and displaces transmitter from vesicles, raising synaptic catecholamines more forcefully than reuptake inhibitors such as methylphenidate. It is approved for attention deficit hyperactivity disorder and for narcolepsy, where it remains one of the most effective treatments for daytime sleepiness.

Immediate-release tablets act for four to six hours; sustained-release capsules extend that to eight or more. Adverse effects are the stimulant set — appetite suppression, insomnia, raised blood pressure and heart rate, irritability — and it is contraindicated in advanced cardiovascular disease, hyperthyroidism, glaucoma, agitated states and with MAO inhibitors. The boxed warning covers abuse and dependence.

Sourcing notes. Dexamfetamine is Schedule II under the 1971 UN Convention and Schedule II in the US. Every consignment needs import and export authorisations, national quotas apply, and the US has had recurring stimulant shortages driven partly by manufacturing quota rather than capacity. Several markets register dexamfetamine only for narcolepsy, or not at all. Storage and transport must meet controlled-drug security requirements, and suppliers will ask for end-user documentation before quoting.
