Writer visits the United States Army Aeromedical Research Laboratory at Fort Rucker in Alabama… Tells about sleep deprivation research there by John and Lynn Caldwell… In ordinary circumstances, as the Caldwells’ research confirmed, sleep-deprived pilots make more errors and respond more slowly.

Dexedrine has been the standard treatment for narcolepsy, and it has had military applications as well: the United States Air Force supplied it to most air crews during the Persian Gulf War… Dexedrine interferes with normal sleep, leaving its users feeling hung over when they awaken. This so-called sleep inertia often prompts the user to take more pills, and a vicious cycle ensues. Provigil preserves normal “sleep architecture.”

Even as sleep disorders increase, firms are pushing their employees to disrupt their normal sleep patterns in order to provide services around the clock. Mentions that this may provide competitive advantages. The capability to resist the mental and physiological effects of sleep deprivation will fundamentally change current military concepts of “operational tempo” and contemporary orders of battle for the military services.

More than a century ago, it was reported that the capacity for doing mental work varies throughout the day. Several empirical studies have revealed time of day variations in performance, with subtle differences between different tasks. Similarly, in participants that are exposed to 36-60 h of sustained wakefulness in controlled laboratory (or constant routine) conditions, significant time of day variations in task performance are reported, with performance being worst for all tasks just after the time of core body temperature minimum (about 0400-0600 h). Subjective alertness levels are closely related to the time-of-day variation in task performance.

In the UK, as in many other countries, sleep-related vehicle accidents peak in the second half of the night (0200-0600 h), and also show a very modest rise in the mid afternoon (1400-1600 h).(10) The modest rise in accidents in the mid afternoon (which is small compared with the nocturnal rise) could reflect the post-lunch decrement in performance.(8) When variation in traffic density is taken into account, the likelihood of a sleep-related vehicle accident is 20 times higher at 0600 h than at 1000 h. Similarly, the risk of injury and fatality during the night shift is significantly greater than it is during traditional daytime working hours.(4,11) The cause of such accidents and injuries is often multifaceted, and the precise contribution of sleepiness is difficult to estimate.

It is now well accepted that transitions between sleep and wakefulness are regulated by complex neurobiologic mechanisms, which, ultimately, can be delineated as oscillations between two opponent processes, one promoting sleep and the other promoting wakefulness.

The role of several neurotransmitter or neuromodulator systems, including noradrenergic, serotonergic, cholinergic, adenosinergic, and histaminergic systems and, more recently, the hypocretin/orexin and dopamine systems, has been clearly established.

Amphetamine-like stimulants are known to increase wakefulness by blocking dopamine reuptake, by stimulating dopamine release, or by both mechanisms.

The NDA is based on positive results of four double-blind, randomized, placebo-controlled studies of NUVIGIL in patients with excessive sleepiness associated with either narcolepsy, SWSD or OSA/HS. The data in this filing show that the primary endpoints of all studies were met and suggest that NUVIGIL is differentiated from PROVIGIL.

“This is the third of five FDA approvals that we will be pursuing over a 15-month time period,” said Dr. Paul Blake, Executive Vice President, Worldwide Clinical Research & Regulatory Affairs at Cephalon. “Cephalon is a pioneer in developing compounds for improving wakefulness, and this on- schedule filing allows us to reinforce our leadership position in the treatment of disorders of sleep and wakefulness,” added Dr. Blake.
