Provigil (Modafinil) - Summary



PROVIGIL (modafinil) is a wakefulness-promoting agent for oral administration. Modafinil is a racemic compound.

PROVIGIL is indicated to improve wakefulness in adult patients with excessive sleepiness associated with narcolepsy, obstructive sleep apnea, and shift work disorder.

In OSA, PROVIGIL is indicated as an adjunct to standard treatment(s) for the underlying obstruction. If continuous positive airway pressure (CPAP) is the treatment of choice for a patient, a maximal effort to treat with CPAP for an adequate period of time should be made prior to initiating PROVIGIL. If PROVIGIL is used adjunctively with CPAP, the encouragement of and periodic assessment of CPAP compliance is necessary.

In all cases, careful attention to the diagnosis and treatment of the underlying sleep disorder(s) is of utmost importance. Prescribers should be aware that some patients may have more than one sleep disorder contributing to their excessive sleepiness.

The effectiveness of modafinil in long-term use (greater than 9 weeks in Narcolepsy clinical trials and 12 weeks in OSA and SWD clinical trials) has not been systematically evaluated in placebo-controlled trials. The physician who elects to prescribe PROVIGIL for an extended time in patients with Narcolepsy, OSA, or SWD should periodically reevaluate long-term usefulness for the individual patient.

Clinical Trials Related to Provigil (Modafinil)

Modafinil - Escitalopram Study for Cocaine Dependence [Completed]

A Placebo-Controlled Trial of Modafinil (Provigil) Added to Clozapine in Patients With Schizophrenia [Completed]
This pilot study is an eight-week, randomized, double-blind, placebo-controlled, escalating dose trial of the novel vigilance-promoting drug, modafinil, added to a stable dose of clozapine in 40 patients with schizophrenia or schizoaffective disorder. Modafinil will be initiated at 100 mg/d. After 2 weeks, the study drug may be increased to 200 mg/d and after 4 weeks, study drug may be increased to a maximum of 300 mg/d. Dose escalation will be based upon persistence of sedation versus emergence of side effects.

Study of the Efficacy and Multiple-Dose Plasma Concentration-Time Profiles of Armodafinil and PROVIGIL [Completed]
The purpose of the study is to compare the overnight efficacy and plasma concentration-time profiles of armodafinil and PROVIGIL, after multiple doses, in patients with excessive sleepiness associated with chronic Shift Work Sleep Disorder (SWSD).

Evaluate the Efficacy of Armodafinil for Patients With B-cell Lymphoma and Severe Fatigue [Withdrawn]
To determine whether armodafinil is more effective than placebo in reducing fatigue.

Modafinil vs Placebo for the Treatment of Methamphetamine Dependence [Completed]
Modafinil is a non-amphetamine type stimulant that acts as a wakefulness-promoting drug, and is approved for managing symptoms of narcolepsy (i. e., daytime somnolence). Its precise mechanism of action in promoting wakefulness remains unclear. This trial is a placebo-controlled double-blind trial of modafinil, on a platform of contingency management (CM) and individual cognitive-behavioral (CBT) counseling, for the treatment of methamphetamine dependence. Participants in this study will complete a 2-week baseline screening period during which they will provide urine samples and complete physical and psychological assessments to establish their eligibility for the study. In addition, participants will be asked to provide a blood or saliva specimen for genetic testing in order to identify genetic variations that influence response to methamphetamine and to treatment with modafinil. Upon successful completion of screening, participants will be randomly assigned to receive either modafinil (400mg qd) or placebo during the 12 weeks of the study. Neither the participants nor study staff will know who is receiving active medication or placebo. Regardless of medication condition, all participants will receive CM and weekly individual CBT counseling sessions to help them stop using methamphetamine and prevent relapse. They will attend the clinical research site (either at the UCLA Hollywood Clinic, or the Rancho Cucamonga site) three times per week, providing urine samples at each visit, completing data measures, and receiving individual CBT counseling on one visit each week. At the end of the 12-week study, the medication or placebo will be discontinued. Participants will return to the research site approximately 30 days following medication discontinuation for a brief health check to assess any possible lingering side effects and complete brief data measures.

Dosage & duration:   200mg Qam and 100mg Qnoon prn taken once to twice a day for the period of 8 months and counting
Other conditions:   rheumatoid arthritis, MTHFR, PAI-4g, Insulin resistant
Other drugs taken:   Folbic, Effexor, Aspirin, metformin, Celebrex, hydroxycloroquin

Provigil review by 37 year old male patient

Overall rating:  
Effectiveness:   Considerably Effective
Side effects:   Mild Side Effects
Treatment Info
Condition / reason:   Central sleep apnea related fatigue
Dosage & duration:   200mg taken 6:30 am and 9:30 am for the period of 9+ months
Other conditions:   Hypertension, ­Premature ventri­cular contractio­ns, seasonal allergies
Other drugs taken:   Lisinopril, Prilosec, Zyrtec, Pepcid, Cialis
Reported Results
Benefits:   Provided increased alertness and perceived cognitive enhancement. Helped me maintain focus and motivation at work. I still drank coffee throughout the day but it was significantly less with Provigil. Prior to Provigil I was prescribed Adderall XR 20 mg. which really had a negative effect on my duty performance. I had TOO much energy and jitters and could not focus on anything for more than 5 minutes. The opposite of what it was prescribed for.
Side effects:   I began having stomach troubles with this drug. I now take Prilosec and Pepcid to counter this. Worth it? Sometimes. Like other reviews here, I found that the positive effects did wear off by the end of the day and dosing again is not smart if you want to get any sleep at all. In addition, I notice increased heart rate at times and seems to exacerbate the frequency and strength of my PVCs.
Comments:   I do like the increased alertness and cognitive enhancement but not sure how Provigil is effecting my heart in the long term.
