Modafinil - the time-shifting drug

Modafinil - the time-shifting drug









The wonders of pharmacology keep appearing regularly, each new drug
seemingly too good to be true. In recent times there have been several
killer apps for the drug industry – chemical substances that replace
depression with a happy disposition or bolster a flagging sex drive to
royal command performance (with encore) levels. Prozac and Viagra
provided benefits so compelling they have entered everyday language and
have a global following. Now there’s another
“drug-most-likely-to-succeed” – this one enables you to stay awake for
40+ hours with close to full mental capacity with few side effects




Modafinil improves memory, and enhances one's mood, alertness and
cognitive powers. The drug has a smoother feel than amphetamines and
enables the user to stay awake and alert for 40 hours or more. Once the
drug wears off, you just have to catch up on some sleep.




Marketed as Provigil ', 'Aletec' and 'Vigicer', Modafinil is a
psychostimulant approved by the US Federal Drug Administration for
improving wakefulness in patients with excessive sleepiness associated
with shift work sleep disorder, obstructive sleep apnea / hypopnea
syndrome and narcolepsy.



Not surprisingly, a drug that enables people to stay awake for 40
hour periods at close to full mental capacity with no real side effects
could quickly gain widespread usage as a time-shifting drug. Got a
project to do, Particularly, when it is devoid of the jitteriness
associated with most drugs commonly used in such circumstance such as
dextroamphetamine, cocaine and the world's most popular drug, caffeine.




"Au natural", (without drugs) humans don't deal well with lack of
sleep and thanks to our fast-paced lifestyle and ever-increasing job
demands, sleep deprivation is a commonplace occurrence in modern culture.




Australian researchers recently found that people who drive after
being awake for more than 17 hours performed worse than those with a
blood alcohol level of .05 percent (the local blood alcohol limit).
Tests the world over have found that sleep deprivation significantly
reduces human performance capabilities, coordination, reaction time and
judgment.




Twenty four hours without sleep is enough to reduce most humans to half their normal mental capacity and it declines rapidly from that point.




Not surprisingly, the military are showing the most interest in the drug.




A large part of battle fatigue is sleep deprivation. When the
military is on the move, almost everybody is required to perform
mission-critical tasks way after they should be asleep. From the
personnel at command HQ to the soldiers at the front, two or three weeks
of activity with just a few hours sleep per day is routine in combat
situations.




For years the military has been exploring new methods to safely combat sleep deprivation and to prevent the associated degradation of performance.




A drug that can double the mental capacity and alertness of a fighting force has more than doubled its effectiveness.




On top of that, with military communications now in real-time, this
is a drug that might keep a small fighting force in heavy contact going
until the sky's open up and help arrives.




But likely candidates for the modafinil fan club aren't hard to find
beyond the military, if the world's caffeine consumption is any
indication.




Caffeine is a drug used across the planet for combating fatigue,
restoring mental performance and enhancing exercise endurance. Caffeine
occurs naturally in more than 60 plant species each contributing to a
whopping global per capita consumption estimated at around 70 milligrams
(mg.) per person per day some 20 years ago. That figure is growing.




More than half of all American adults consume 300 mg. or more of
caffeine every day. Nine out of ten Americans consume caffeine every
day.




The most prolific caffeine contributor is coffee, the second most
valuable legally traded commodity on Earth (after oil) with annual
global retail sales more than US$70 billion. Caffeine is also contained
in tea, chocolate and caffeine-enhanced cold drinks such as Coca Cola,
Pepsi Cola, Red Bull et al.



In recent times, the caffeine-enhanced softdrink market has burgeoned.




In 1970, the average american drank 36 gallons of coffee and 23
gallons of carbonated soft drinks. By the year 2000, coffee consumption
had more than halved to 17 gallons and soft drinks had grown 130% to 53
gallons. Caffeine consumption has grown significantly and a large
proportion of that caffeine was imbibed with the sole aim of performance
enhancement.




Unfortunately, the benefits of caffeine are such that constant use
builds immunity, leaving the jitteriness but not the enhanced
performance and most of the world's habitual coffee consumption is used
to stave off the effects of caffeine withdrawal. Modafinil does not
appear to have such drawbacks, though users should be acutely aware that
prolonged and regular use of the drug will lead to health issues.



Almost any profession requires being switched on (mentally alert) at
least some of the time, and if it's good enough for the most
scientifically-analysed elite warriors on the planet, we suspect it'll
be good enough for all other armed forces personnel, emergency and
rescue workers, police, firefighters, and doctors, who are faced with
very long hours of making potential life and death decisions ... and all
those who need or choose to work long hours in their profession, from
truck and taxi drivers, through to computer programmers.




Sportspeople are another likely marketplace - at the June 2003 United
States Track and Field Championships, a star studded field of athletes
tested positive for modafinil including sprinters Kelli White, Chris
Phillips, Calvin Harrison and Chryste Gaines, hurdlers Sandra Glover and
Eric Thomas and hammer thrower John McEwen. Modafinil now attracts a
two year ban from all elite sports, but can be expected to proliferate
at any level where drug testing does not occur.




Then there will be those who will take Modafinil for recreational
purposes - it just might be the ultimate party drug with the user awake,
alert and balanced and no problems remembering what happened or what
got said the next morning.




So how good is it? Researchers recently had the opportunity to compare a group of America's finest with and without modafinil.




The testing was done using elite F-117A Nighthawk pilots - an F117-A
Nighthawk is one of those black triangular stealth attack aircraft used
with surgical precision by the US airforce in all recent wars.



Just over 60 Nighthawks were built and only one F-117A unit exists -
the 49th Fighter Wing, at Holloman Air Force Base, N.M. The
single-seater can fly at high subsonic speeds for unlimited distances
with air refuelling. On their first deployment to Kuwait in 1992, a
group of F-117s flew non-stop for 18.5 hours, a record for single-seat
fighters that stands today.




With the right pilot aboard, the Nighthawk is a formidable weapon - a
precision-strike aircraft with exceptional combat capabilities
particularly suited for penetrating high-threat airspace with its
stealth and speed and hitting critical targets with surgical accuracy
using laser-guided weapons.



During Operation Desert Storm the Nighthawk flew approximately 1,300
sorties scoring direct hits on 1,600 high-value targets in Iraq. At
US$45 million each, the Nighthawk is one of America's most effective
weapons. When the United States declares war on you, the chances are the
Nighthawk will be the first to tell you hostilities have begun. It was
the ONLY U.S. or coalition aircraft to strike targets in downtown
Baghdad and it led the first Allied air strike on Yugoslavia in March,
1999.




Our test group was the people who fly these aircraft - people who
push the limits of human performance day-today using one of the most
expensive and sophisticated aircraft on the planet. For the records, the
F117-A is built by Lockheed Aeronautical Systems, is powered by two
General Electric F404 non-afterburning engines is 19.4 metres long, 3.9
metres high, weighs 23,625 kilograms and has a wingspan of 13.2 metres.




The Laboratory and simulator tests studied the effects of being awake for 40 hours on alertness and flight performance.




The tests were repeated every five hours to help track the pilots'
level of fatigue by monitoring body and brain activities. One test is a
one-hour flight simulator mission. Researchers looked at the aviators'
ability to monitor flight gauges and calculate basic mathematical
equations. They also monitored eye movements and changes in pupil size.




While no one crashed or even came close to crashing, researchers said
flight precision most noticeably changed between 33 hours and 38 hours
into the test.




Armed with this initial data, the scientists returned to Holloman a few months later for the modafinil study.




Scientists said that while the pilots were on the medication, their
performance "significantly improved," especially after 25 hours without
sleep. The pilots also sustained brain activity at almost normal levels
despite their sleeplessness.




During the simulator tests, modafinil "significantly" reduced the effects of fatigue during flight manoeuvres, researchers said.




Under the influence of modafinil, flight performance degraded by 15
to 30 percent. Performance by pilots without the medication degraded by
60 to 100 percent compared to fully rested performance levels.




The results of the testing were heavily conclusive - modafinil was effective for reducing the impact of fatigue.




International biopharmaceutical company Cephalon owns the worldwide rights to Modafinil.



Modafinil is available in more than 20 countries and is marketed
under the brand name PROVIGIL in the United States, United Kingdom,
Ireland, Italy, South Korea, Belgium and Luxembourg. Modafinil is
available in other countries under the brand names, ALERTEC, MODIODAL,
MODASOMIL, MODAVIGIL and VIGIL.




Modafinil is listed as a Schedule IV drug under the Controlled
Substances Act. Schedule IV drugs as a class have a lower abuse
potential than drugs listed in Schedule II or III. Other examples of
Schedule IV drugs include Ambien, Xanax and Ativan. Examples of Schedule
II drugs include Actiq, morphine, methadone and methylphenidate
(Ritalin). Examples of Schedule III drugs include anabolic steroids,
codeine and hydrocodone with aspirin or Tylenol, and some barbiturates.




Cephalon recently announced that it has filed an application with the
U.S. Food and Drug Administration (FDA) requesting marketing approval
of a new proprietary form of modafinil for the treatment of attention-
deficit/hyperactivity disorder (ADHD) in children and adolescents
between the ages of six and 17.

Adderall, Ritalin and other “smart drugs” have become popular among
college students and young professionals, who use them to enhance
performance. The drugs are normally
prescribed to treat attention deficit hyperactivity disorder (ADHD), but
healthy students use them to get a leg up in school, by improving
focus, concentration and memory. The question is, do they work?

Maybe not, according to a new study from the University of
Pennsylvania. Students who took Adderall didn’t actually perform better
on tests of cognitive function — they only thought they did. Casey Schwartz blogged about the findings on the Daily Beast:

The research team tested 47 subjects, all in their
twenties, all without a diagnosis of ADHD, on a variety of cognitive
functions, from working memory — how much information they could keep in
mind and manipulate — to raw intelligence, to memories for specific
events and faces. Each subject was tested both while on Adderall and on a
placebo; in each condition, the subjects didn’t know which kind of pill
they were receiving.

The researchers did come up with one significant finding. The last
question they asked their subjects was: “How and how much did the pill
influence your performance on today’s tests?” Those subjects who had
been given Adderall were significantly more likely to report that the
pill had caused them to do a better job on the tasks they’d been given,
even though their performance did not show an improvement over that of
those who had taken the placebo.
It’s not surprising that Adderall gave students an inflated sense of
productivity, Schwartz writes, given that the drug — a close cousin of
amphetamine — “unleashes the feel-good neurotransmitter dopamine,
triggers the brain’s reward system, and can produce a mild sense of
euphoria.” (More on Time.com: Drug Surprise: Meth Makes You Feel Almost As Cuddly as Ecstasy)

So whether or not the drug boosts performance on cognitive tests in
the short-term, could it be possible that its “euphoric” effect simply
makes studying more pleasurable, helping student achievement by ramping
up enthusiasm for academics overall? (More on Time.com: Clues to the Genetic Roots of ADHD)

Schwartz points to a personal essay about performance enhancement by a recent college senior, Molly Young. Writing
for N+1, Young noted, “Of course, I could have studied in college
without Adderall, just like I did in high school — I just couldn’t have
studied with such ecstasy.”

Then again, ecstasy doesn’t necessarily mean creativity, which is
another marker of cognitive performance, and one that’s hard to pin down
in a scientific study. “Though I could put more words to the page per
hour on Adderall, I had a nagging suspicion that I was thinking with
blinders on,” wrote Slate’s Joshua Foer in 2005. (More on Time.com: A Five-Minute Brain Scan Tracks Kids’ Development and May Spot Disorders)

UPDATE: It bears noting that the new study, which
has not yet been published (it was presented at the annual Society of
Neuroscience conference in November), is contradicted by a body of
evidence showing actual cognitive benefits of the drug. Healthland’s
Maia Szalavitz reported:

The benefits of enhancement include increased alertness
and focus and improvement in some types of memory. Research shows that
in normal people, stimulants consistently and significantly improve
learning of material that must be recalled days later — exactly what you
want from a drug when you are prepping for exams. The drugs even seem
to improve certain aspects of judgment. One study of 36 normal women and
men found that they were more likely to choose to delay gratification
and receive a larger monetary reward when given amphetamines than settle
for a smaller amount of money immediately. Improvements in memory and
cognitive control have been reported in multiple studies, mainly using
Ritalin and amphetamines.
Research suggests, however, that the drug doesn’t improve performance
evenly. Many users receive no performance boost, as evidenced by the
current University of Pennsylvania study as well as previous work.
Szalavitz wrote:

Interestingly, those who have the least ability in a
particular area are likely to see the greatest drug-related improvement.
In fact, on some tests of cognition, the smartest people actually
showed performance reductions, a result that may address some of the
concerns over “cheating”: on tasks involving working memory and
impulsivity, stimulants had a leveling effect, allowing below-average
performers to catch up to their peers, not dominate them. According to
Farah, the typical student user is actually not the overachieving
brainiac but a “white male frat brother with a B average.”
Why it works for some and not others isn’t entirely clear, but nota bene:
don’t take Adderall or Ritalin without a doctor’s prescription,
especially if you suffer from psychosis, mood disorders or high blood
pressure.

This post has been updated to reflect the fact that past research
suggests taking “smart drugs” may have a significant effect on
performance.
