The medicine is used to treat severe sleepiness caused by sleep apnea, narcolepsy or sleep disorder. The tablets affect different parts of the brain. Its most important action is to increase the rate of psychical reactions. This phenomenon refers to the lower part of the intermediate brain in which there is an excitation of the nerve pathways in which the action of orexin/hypocretins, plays an important role in the management of sleep-wakefulness. Moreover, it activates sympathetic receptors of the nervous system, increases activity and stimulates glycine and histamine transmitters. The pills also make a stronger effect on the cortex. Tablets also reduce the activity of inhibiting nerve cells, which has gamma-aminobutyric acid. The drug does not contribute to the excitation of the dopamine system in the nervous system, which is the most important effect among amphetamines.
