DESCRIPTION
Modacare 200 mg is a central nervous system stimulant that is used to treat excessive daytime sleepiness with narcolepsy, sleep apnea and shift work sleep disorder. Modacare 200 mg increases the amount of dopamine in your brain that helps you stay awake and focused. It is taken as recommended by your GPs. Modacare 200 mg helps improve alertness without crashing down in a sudden way. In case you experience symptoms of overdose such as fast heartbeat and agitation, please seek emergency medical attention.
Mechanism of action
Modafinil increases wakefulness and alertness by the following mechanisms:
- Dopamine Transporter (DAT) Inhibition – Modafinil is thought to bind to the dopamine transporter and inhibit reuptake of dopamine. This could improve dopamine signaling in the brain and help to promote wakefulness and alertness.
- Orexin activation – Modafinil may activate orexin pathways that are implicated in the regulation of the sleep-wake cycle and maintaining daytime alertness.
- GABA regulation – Modafinil may reduce GABA activity in some brain regions. Since GABA is associated with sleep and relaxation this effect may help prevent drowsiness.
