Modafinil is a prescription drug that promotes wakefulness and increases the feeling of wakefulness in adults with excessive daytime sleepiness due to particular sleep disorders. Modafinil is indicated for use in narcolepsy, obstructive sleep apnea-excessive sleepiness and shift work sleep disorder. The drug has its action in the central nervous system and affects different neurotransmitter systems responsible for the feeling of alertness and wakefulness.
Modafinil 400mg indicates the total quantity of the drug at 400 milligrams. Nevertheless, 400mg cannot be considered the standard dosage because in a number of cases the recommended dosage of the drug is 200mg daily. In shift work sleep disorder the medicine is taken prior to the beginning of work shift. The dosage should be determined depending on the disease and patient's individual needs.
In case of narcolepsy modafinil is used for reduction of excessive sleepiness during daytime activities. In case of obstructive sleep apnea it may be used in case of residual excessive sleepiness, but does not help to eliminate airway obstruction. In shift work sleep disorder it promotes wakefulness while working at unusual hours because of rotating or night shift work.
Nevertheless, it should be pointed out that Modafinil has another pharmacological effect compared to other stimulants since it does not only produce wakefulness but also acts upon the certain signaling systems of the brain responsible for attention. It means that Modafinil is not an energy booster in itself but a medicine used for treatment of some diseases related to increased drowsiness.
Thus, when studying Modafinil 400mg, it is important to understand that the medicine strength and the dose needed for treatment of a certain condition are not the same thing since more does not necessarily mean better effect. Moreover, Modafinil is able to interact with other medications since it affects the activity of certain liver enzymes.
Generally speaking, Modafinil is an effective prescription medicine that is used for treatment of some sleep disorders characterized by increased sleepiness. Modafinil 400mg is quite a strong preparation compared to the usual dose of the medicine for certain conditions. Therefore, the information about the dose is quite important when providing the information about Modafinil 400mg.
