Central nervous system (CNS) stimulants are agents that increase physical activity, mental alertness and attention span. The exact mechanism of action of these agents or receptors they may affect, is not known.



Central nervous system stimulants are used to treat attention-deficit hyperactivity disorder (ADHD) and narcolepsy.



Think about what happens in the morning after you’ve consumed your first cup of coffee. You feel an increase in energy, alertness, and your ability to focus. And what happens on mornings when you skip that cup of coffee? You likely feel more tired or maybe find it harder to concentrate. This is because coffee contains caffeine, which is a stimulant drug. Some stimulants, like coffee, are used every day by people who want to stay awake or increase their alertness. While stimulants can be used safely, they can be dangerous if not taken correctly. Some stimulants are available only through prescription, and others are illegal. Let’s discuss stimulants in more detail.

Stimulants are drugs that ‘stimulate’ the central nervous system. In other words, they increase the activity in your brain. Though each stimulant has unique effects, all stimulants increase your heart rate, blood pressure, and body temperature. By increasing the electrical activity in your brain, stimulants cause you to be more alert, decrease fatigue, and prolong physical activity. Stimulants can also improve your mood and increase self-confidence. For these reasons, stimulants are also referred to as ‘uppers.’


Medical Uses for Stimulants

You’ve probably taken stimulant medication in the past without realizing it. For example, if you have ever taken extra strength Excedrin, you have taken a stimulant. Below are other examples of medical uses for stimulants:

  • Caffeine is often added to painkillers in order to make them more effective.
  • Because of their ability to improve mood and self-confidence, doctors prescribe stimulants in combination with anti-depressants to treat depression.
  • Stimulants are effective in treating cognitive disturbances in HIV patients and in cancer patients going through cranial irradiation.
  • Some stimulant drugs, such as Adderall and Concerta, are useful in controlling the impulsive behaviors, inattentiveness, and hyperactivity that are associated attention-deficit/hyperactivity disorder (ADHD).
  • Stimulants are used to help people with narcolepsy stay awake.
  • Because stimulants relax the bronchial muscles, almost all asthma medications contain stimulants.
  • Stimulants are also found in both prescription and non-prescription diet pills due to their appetite-reduction abilities.
