Modafinil Provigil by Ray Sahelian, M.D.
Modafinil (commercial trade names Provigil (US, UK), Vigil (Germany), Modalert (India), Modiodal (France, Mexico), Modavigil (Australia), Alertec (Canada), is a drug prescribed to treat narcolepsy. Modafinil is made by the pharmaceutical company Cephalon Inc.
Modafinil Provigil is a psychostimulant. Modafinil
improves wakefulness and vigilance, but its pharmacological profile is different
from the amphetamines, methylphenidate (Ritalin) or cocaine. Modafinil is less
likely to cause jitteriness or anxiety than traditional stimulants.
Subjectively, it feels smoother and cleaner than the amphetamines.
Modafinil and sleep deprivation
The non-amphetamine, wake-promoting drug, modafinil counters the adverse effects
of sleep deprivation on working memory.
In a randomized, double-blind study, Dr. Robert Joseph Thomas, of Beth Israel
Deaconess Medical Center, Boston, and Dr. Kenneth K. Kwong of Massachusetts
General Hospital, Charlestown examined the effect of modafinil on working memory
and brain activation in the executive network following overnight sleep
deprivation.
Functional magnetic resonance imaging was used to assess the functional
neurobiology of executive function in eight sleep-deprived medication-free men
(ages 21 to 35 years) treated with 200 mg of modafinil or placebo. They
underwent a verbal working-memory task with 3 levels of difficulty.
Subjects in the sleep-deprived condition, had approximately 28 hours of
continuous wakefulness, and in the rested condition, had 8 hours of scheduled
sleep opportunity. The team assessed brain activation patterns and regional
signal intensity based on the blood-oxygen level-dependent signal.
Modafinil countered the ill effects of sleep deprivation on working memory, but
only when the task difficulty was moderate.
Dr. Sahelian says: There are a number of natural supplements that
could be helpful in sleep deprivation and as a good natural alternative to
modafinil. These include Mind Power Rx
brain booster,
Eyesight Rx, acetylcarnitine, DMAE, and
other nutritional supplements.
Modafinil and depression -
modafinil for mood elevation

Modafinil, a medication for the excessive sleepiness associated with narcolepsy,
has been hypothesized to improve not just alertness but mood as well. The
purpose of this study was to determine how treatment with modafinil affects mood
in healthy volunteers. Normal healthy volunteers (n = 12, 10 men and 2 women;
30-44 years) underwent a 3-day, counterbalanced, randomized, crossover,
inpatient trial of modafinil (400 mg daily) versus placebo with 4-day washout
period between 2 treatments. Mood was assessed daily using both the Positive and
Negative Affect Schedule and a general mood scale, which consisted of 10 bipolar
adjective ratings based on a severity scale ranging from 1 to 10. Modafinil
increased general mood and Negative Affect scales relative to placebo and had a
significant effect on Positive Affect scales. These results suggest that
modafinil may have general mood-elevating effects accompanied by increased
negative affect (anxiety).
Dr Sahelian says: it is possible that a medication (such as an
amphetamine) may help depression or improve mood
in the short term, but then later cause a crash with
severe depression or other side effects.
Modafinil side effects
The most common modafinil side effects are headache, nausea, nervousness, and
rhinitis. Additional modafinil side effects include diarrhea, back pain,
anxiety, insomnia, dizziness, and dyspepsia. Additional modafinil side effects
may be discovered as more people use this drug for prolonged periods. Could
heart problems occur?
Modafinil questions
I am taking modafinil. I have narcolepsy and am searching everyday for something
that keeps me awake. My mind is awake all the time with monafinil, but does
tyrosine make you have more energy as a whole or just wired.
A. Tyrosine usually makes one more wired. Many people tell us
Eyesight Rx and or Mind Power Rx help the mind stay alert and focused and
provide good energy. Perhaps they can be a substitute for modafinil in some
people.
