Wakefulness-promoting agent
Wakefulness-promoting agent[edit | edit source]
A wakefulness-promoting agent is a type of drug that is used to enhance alertness and wakefulness in individuals. These agents are often prescribed to treat conditions such as narcolepsy, shift work sleep disorder, and obstructive sleep apnea. They are distinct from traditional stimulants in that they generally have a lower potential for abuse and fewer side effects.
Mechanism of Action[edit | edit source]
Wakefulness-promoting agents work by affecting various neurotransmitter systems in the brain. The exact mechanism of action can vary between different agents, but they often involve modulation of the dopamine and norepinephrine pathways. For example, modafinil, one of the most well-known wakefulness-promoting agents, is believed to increase the availability of these neurotransmitters, thereby enhancing wakefulness and alertness.
Common Wakefulness-promoting Agents[edit | edit source]
- Modafinil: Modafinil is a widely used wakefulness-promoting agent that is prescribed for narcolepsy, shift work sleep disorder, and obstructive sleep apnea. It is known for its relatively mild side effect profile compared to traditional stimulants.
- Armodafinil: Armodafinil is a derivative of modafinil and is used for similar indications. It is the R-enantiomer of modafinil and is thought to have a longer duration of action.
Clinical Uses[edit | edit source]
Wakefulness-promoting agents are primarily used in the treatment of sleep disorders. They are prescribed to help patients maintain wakefulness during the day and improve their overall quality of life. In addition to their use in sleep disorders, these agents are sometimes used off-label for conditions such as attention deficit hyperactivity disorder (ADHD) and depression, although such uses should be approached with caution.
Side Effects[edit | edit source]
While wakefulness-promoting agents are generally well-tolerated, they can cause side effects in some individuals. Common side effects include headache, nausea, nervousness, and insomnia. More serious side effects are rare but can include allergic reactions and psychiatric symptoms.
