Neuropathic pain<br />

The International Association for the Study of Pain<br />

(IASP) has defined neuropathic pain as “pain initiated<br />

or caused by a primary lesion or dysfunction of the<br />

ner vous system”. These lesions may be in the peripheral<br />

or central nervous system, and frequently both<br />

systems are involved with chronic neuropathic pain<br />

states. Examples include phantom limb and spinal<br />

cord injury pain, painful diabetic neuropathy, postherpetic<br />

neuralgia, sciatica, trigeminal neuralgia, and<br />

drug-induced (e.g. vinca alkaloids) neuropathy.<br />

Neurotransmitter<br />

A chemical substance in the brain that either excites<br />

or inhibits neural function.<br />

New Chemical Entity (NCE)<br />

A compound of a completely new chemical form,<br />

which has not been previously approved, and therefore<br />

can be patented.<br />

Nociceptors<br />

Sensory receptors responsible for nociception, the<br />

perception of pain in response to potentially damaging<br />

stimulus.<br />

NSAIDs<br />

Non-steroidal anti-inflammatory drugs.<br />

Off-label<br />

The use of a drug for a medical condition other than<br />

for which it was officially approved and marketed.<br />

Onset of action<br />

The length of time it takes for a medicine to start to work.<br />

Open label<br />

A study in which all parties (patient, physician and<br />

study coordinator) are informed of the drug and dose<br />

being administered.<br />

Opioids<br />

A synthetic drug (such as methadone) possessing narcotic<br />

properties similar to opiates but not derived<br />

from opium.<br />

Parkinson’s disease (PD)<br />

PD is a degenerative disorder of the central nervous<br />

system that affects the control of muscles, and so may<br />

affect movement, speech and posture. Parkinson’s disease<br />

belongs to a group of conditions called movement<br />

disorders. It is often characterized by muscle<br />

rigidity, tremor, a slowing of physical movement<br />

(bradykinesia), and in extreme cases, a loss of physical<br />

movement (akinesia). The primary symptoms are the<br />

result of excessive muscle contraction, normally<br />

caused by the insufficient formation and action of<br />

dopamine, which is produced in the dopaminergic<br />

neurons of the brain. Secondary symptoms may<br />

include high-level cognitive function and subtle language<br />

problems. PD is both chronic, meaning it persists<br />

over a long period of time, and progressive.<br />

Pivotal study<br />

Usually a phase III study which presents the data that<br />

the governmental agencies responsible for approving<br />

the marketing of pharmaceutical products (e.g. the US<br />

FDA and EMEA) use to decide whether or not to<br />

approve a drug. A pivotal study will generally be wellcontrolled,<br />

randomized, of adequate size, and whenever<br />

possible, double-blind.<br />

“ON” time<br />

During “ON” times, patients report they feel relatively<br />

fluid, clear, and in control of their movements. Often,<br />

symptoms of PD may be invisible to all but professionals.<br />

Placebo<br />

An inactive substance designed to resemble the drug<br />

being tested. It is used as a control to rule out any<br />

psychological effects testing may present.<br />
