Pharmacological class Central Nervous System (CNS) Stimulant / Eugeroic
Common purpose Promotion of Wakefulness
Origin Synthetic Compound

What Type of Medicine is Modafinil?

Modafinil Medochemie is a branded, synthetic, prescription-only medicine produced by the manufacturer Medochemie Ltd. Its active component, modafinil, is categorized as a Central Nervous System (CNS) stimulant and is clinically recognized as a eugeroic or wakefulness-promoting agent. This classification indicates its function is to enhance and sustain alertness. The medication is uniformly prepared as an oral tablet, which represents the standardized solid dosage form used for administration. The designation as a eugeroic distinguishes its action profile, emphasizing vigilance promotion over the generalized stimulation seen in older drug classes.

Composition and Origin of the Active Ingredient

The composition of this pharmaceutical product centers exclusively on the active ingredient, modafinil, confirming it as a single-active ingredient product. Modafinil is a synthetic compound, meaning its unique chemical structure is created through laboratory synthesis. This synthetic origin ensures a predictable chemical identity crucial for pharmaceutical standardization. Modafinil-containing medicines are used for the management of conditions involving excessive sleepiness.

General Purpose of a Eugeroic Agent

The fundamental purpose of this eugeroic agent is to achieve and sustain wakefulness and increase alertness during planned waking hours. This critical benefit is achieved through the drug's influence on the brain’s sleep-wake cycle, rather than broad neurological activation. This targeted approach allows modafinil to address profound excessive daytime sleepiness, which is a typical use scenario for this class, by helping adult patients remain attentive and functional without the non-selective stimulation profile of traditional CNS stimulants.

What should I know about interactions with other medicines?

Interaction Map: Interactions with other medicines and products — official regulatory information for Modafinil Medochemie

Interaction Scope

Category Affected Substances/Products
Medicinal product categories with documented interactions Steroidal Contraceptives, CYP3A4/5 Substrates, CYP2C19 Substrates, other Central Nervous System (CNS) Stimulants, Monoamine Oxidase Inhibitors (MAOIs)
Specific interacting medicines (if explicitly listed) Ethinyl Estradiol and Progestins (in contraceptives), Diazepam, Phenytoin, Cyclosporine, Triazolam

Mechanistic basis of interactions (only if stated in label):

  • CYP3A4/5 Enzyme Induction: Modafinil is documented to modestly increase the activity of this enzyme system, resulting in reduced systemic exposure of co-administered drugs that are substrates for CYP3A4/5.
  • CYP2C19 Enzyme Inhibition: Modafinil is also documented as a reversible inhibitor of CYP2C19, resulting in increased circulating levels of drugs largely cleared via this pathway.
  • Pharmacodynamic Interaction: Potential for additive wakefulness effects when combined with other CNS stimulants.

Timing-based interaction rules (if applicable):

  • The reduced effectiveness of steroidal contraceptives (due to enzyme induction) requires the use of alternative or concomitant non-hormonal contraception during modafinil treatment and for two months after discontinuation.

Population-specific interaction notes (if applicable):

  • In individuals with severe hepatic impairment, the overall clearance of modafinil is reduced, which may influence the severity of potential drug-drug interactions.

Interaction-related restrictions:

  • The label advises patients to avoid the use of alcohol while taking modafinil.
  • Co-administration with Monoamine Oxidase Inhibitors (MAOIs) is cautioned against due to the risk of a severe acute hypertensive response.

Connection to the overall interaction profile

Regulatory documents define the product’s interaction structure primarily through its dual, opposing influence on metabolic enzymes: modest induction of CYP3A4/5 and inhibition of CYP2C19. This metabolic activity establishes the requirement for dose separation or alternative methods for co-administered drugs sensitive to these pathways, most notably hormonal contraceptives. Official labeling also includes specific cautions for pharmacodynamic effects, such as potential additive stimulation with other CNS agents, and mandates restrictions on the concurrent use of alcohol.

Mechanism of Action

How Modafinil Medochemie Works

Modulating the Dopamine Transporter

The action of modafinil is initiated by its interaction with key Central Nervous System ( CNS) arousal pathways, resulting in a targeted, sustained modulation of wakefulness-regulating circuits. Modafinil exerts its primary molecular action by binding to the Dopamine Transporter ( DAT) protein, thereby inhibiting the reuptake of the neurotransmitter dopamine from the synapse. This action increases the extracellular concentration of dopamine, which serves as the initial molecular signal to modulate downstream arousal pathways.

Activating the Orexin System

The increased dopamine availability indirectly leads to the crucial enhancement and activation of Orexin (Hypocretin) neurons in the hypothalamus. The orexin system is central to the regulation of CNS arousal tone. This pathway modulation, along with augmented histamine and norepinephrine signaling, contributes to an alteration in the brain's sleep-wake balance, sustaining the activity of arousal-controlling pathways. This sustained modulation affects the neurochemical control over the activity of CNS arousal pathways, and the resulting physiological effect is the sustained activity of the central arousal systems.

Dosage and Administration Information

The administration of this medicine follows established pharmacological standards. The drug is supplied as an oral tablet in standard 100 mg and 200 mg strengths and is intended to be swallowed whole. The usage pattern is defined by a single daily dose.

Standard Dosing and Timing

The standard daily dosage is 200 mg, which is typically taken once per day. The timing of this single dose is determined by the specific condition being managed:

  • For patients using the medication for Narcolepsy or residual Excessive Sleepiness associated with Obstructive Sleep Apnea (OSA), the full dose is administered once daily in the morning.
  • For managing Shift Work Sleep Disorder (SWD), the single dose is taken approximately one hour prior to the start of the scheduled work shift.

This medication may be taken either with or without food; while food may delay absorption, it does not alter the total amount of medicine that enters the bloodstream. Doses up to 400 mg per day have been used, in either a single or two divided doses, although there is no consistent evidence of additional benefit beyond the 200 mg daily standard.

Population-Specific Adjustments

Dose reductions are utilized for specific patient groups. For patients diagnosed with severe hepatic impairment, the standard daily dosage is reduced by one-half (e.g., to 100 mg/day). Due to the potential for lower clearance, lower starting doses may be considered for older adults (geriatric patients). If a dose is forgotten, the patient must not take two doses at once to compensate.

Recent Clinical Evidence

Evidence for the Management of Narcolepsy-Associated Excessive Sleepiness

Research was studied for its use in adult patients diagnosed with Narcolepsy. The evidence base for this condition primarily consists of short-term Randomized Controlled Trials (RCTs), Systematic Reviews, and Meta-analyses. Research examined objective measurements of wakefulness and patient-reported outcomes related to sleepiness. Findings describe patterns observed in the studies over short periods, complemented by long-term open-label extension studies that observe how symptoms evolved. The evidence base, however, does not provide well-characterized data regarding cataplexy symptoms; the findings are inconclusive.


Evidence for Excessive Sleepiness in OSAHS and SWSD

The medication was evaluated in adult patients with residual excessive sleepiness from Obstructive Sleep Apnea/Hypopnea Syndrome (OSAHS) and in those with Shift Work Sleep Disorder (SWSD). These studies explored changes in objective wakefulness and performance using Short-term RCTs. The data show patterns related to measurements of alertness, but evidence quality varies across studies, and regulatory bodies have had mixed findings. For both conditions, some official health agencies concluded that the evidence of clinical benefit was not sufficient to support these uses.


Research Limitations and Study Gaps

Follow-up durations were limited across many trials, meaning that long-term effects are not fully established for any indication. Studies explored the use in older adults but data are still emerging, and the results apply only to the populations studied. A key gap lies in the regulatory divergence concerning the evidence for both OSAHS and SWSD, which reflects scientific uncertainty in the interpretation of the effectiveness data.
