Which medications are known for relieving nervousness and tension by slowing down the central nervous system?

Benzodiazepines are a class of medications primarily used to treat anxiety and other conditions related to nervousness and tension. They work by enhancing the effect of a neurotransmitter called gamma-aminobutyric acid (GABA), which has inhibitory effects on the neurons in the central nervous system. This action results in a calming effect, leading to reduced feelings of anxiety, increased relaxation, and an overall slowed response of the central nervous system. Due to their ability to induce sedation and decrease anxiety, benzodiazepines are commonly prescribed for various anxiety disorders and situations where stress relief is necessary.

Other medication classes, such as analgesics, including opioids and NSAIDs, do not primarily target anxiety or tension relief. While opioids may have sedative properties, they are primarily used for pain management rather than specifically for relieving nervousness. NSAIDs, on the other hand, are focused on addressing inflammation and pain rather than central nervous system activity. Beta-blockers are typically used to manage heart conditions and can help with some physical symptoms of anxiety, but they do not directly affect central nervous system activity in the same way benzodiazepines do.
