Amphetamine

A drug that stimulates dopamine release in the central nervous system (CNS), causing elevated mood and increased wakefulness, alertness, concentration, and physical performance. Amphetamines have a high potential for abuse and come in a variety of forms (pills, liquid, or powder). Withdrawal can produce a wide range of uncomfortable symptoms. It is used clinically to treat attention-deficit/hyperactivity disorder (ADHD) and narcolepsy.

Typical symptoms include maladaptive psychological or behavioral changes such as euphoria with enhanced vigor and alertness or grandiosity; affective blunting with fatigue or sadness; changes in sociability ranging from gregariousness to social withdrawal; hypervigilance and sensitivity, sometimes leading to fighting; anxiety, tension, or anger; stereotyped, repetitive behavior; and impaired judgment. Perceptual disturbances also may occur. Accompanying physical signs may include very rapid or very slow heartbeat, elevated or lowered blood pressure, perspiration or chills, nausea, evidence of weight loss, muscular weakness, chest pain, and confusion.

Cessation of prolonged heavy use of amphetamine or a related substance produces a dysphoric mood and physiological changes such as fatigue, vivid and unpleasant dreams, insomnia or hypersomnia, and increased appetite.

A group of chemicals that stimulate the cerebral cortex of the brain; often misused by adults and adolescents to control normal fatigue and to induce euphoria. Used clinically to treat hyperkinetic syndrome and narcolepsy.

The most powerful stimulant known.

Synthetic stimulant drugs used in medicine to reduce fatigue, or to decrease appetite.

Stimulants that speed up the heart and breathing; can cause anxiety, sleeplessness, and loss of appetite.

Central nervous system stimulant used to treat narcolepsy and some forms of depression and attention-deficit disorders. It alleviates fatigue, promotes alertness, and decreases appetite. Over-dosage causes gastrointestinal complaints, rapid heart rate, restlessness, sleeplessness, and in very high doses hallucinations and feelings of panic. It has a high potential for abuse, resulting in tolerance and dependence. Slang: speed.

A sympathomimetic drug that has a marked stimulant action on the central nervous system. It alleviates fatigue and produces a feeling of mental alertness and well-being. The drug has been used in the treatment of narcolepsy, mild depressive neuroses, and obesity. It is administered by mouth; side-effects include insomnia and restlessness. ‘Tolerance of amphetamine develops rapidly, and prolonged use may lead to dependence.

A group of drugs closely related to adrenaline which act by stimulating the sympathetic nervous system. When taken by mouth they have a profound stimulating effect on the brain, producing a sense of well-being and confidence and seemingly increasing the capacity for mental work. They are, however, drugs of dependence and their medical use is now strictly limited — for example, to the treatment of narcolepsy.

A colorless liquid that volatilizes slowly at room temperature. It is a central nervous system stimulant. The preparation most commonly used is the sulfate form, marketed as tablets or capsules.

(Speed, uppers, crank, bennies, meth, or crystal) are powerful CNS stimulants. They are controlled substances legitimately used for short¬ term diet control in obesity and for narcolepsy. They have the ability to relieve sleepiness and fatigue and increase alertness, confidence, and short-term performance. Truck drivers, pilots, entertainers, and athletes may use amphetamines nonmedically to enhance their performance.

One of a group of powerful stimulants that are made artificially.

Synthetic chemicals (as opposed to plant derivatives) that are strong central nervous system stimulants.
