Generally, drugs outlined within the ATC code N should be included in this category. Please see WP:PHARM:CAT for more information. Wikimedia Commons has media related to Nervous system drugs .
Illegal drugs such as cocaine and MDMA also affect dopamine, serotonin, and norepinephrine. Norepinephrine is synthesized by the body from the amino acid tyrosine, [3] and is used in the synthesis of epinephrine, which is a stimulating neurotransmitter of the central nervous system. [4]
Anticholinergics (anticholinergic agents) are substances that block the action of the acetylcholine (ACh) neurotransmitter at synapses in the central and peripheral nervous system. [1] [2] These agents inhibit the parasympathetic nervous system by selectively blocking the binding of ACh to its receptor in nerve cells.
They do produce central nervous system depression, but they also excite certain areas of the central nervous system. To remain true to the term "depressant", opioids cannot be classified as such. For opioid agonists and opium derivatives, these are classified differently. These drugs are more correctly identified as "analgesic" or "narcotic ...
A stimulant is an overarching term that covers many drugs including those that increase the activity of the central nervous system and the body, [5] drugs that are pleasurable and invigorating, or drugs that have sympathomimetic effects. [6] Sympathomimetic effects are those effects that mimic or copy the actions of the sympathetic nervous ...
Muscarinic antagonists counter this parasympathetic "rest-and-digest" response, and also work elsewhere in both the central and peripheral nervous systems. Drugs with muscarinic antagonist activity are widely used in medicine, in the treatment of low heart rate, overactive bladder, respiratory problems such as asthma and chronic obstructive ...
Amphetamine [note 2] (contracted from alpha-methylphenethylamine) is a central nervous system (CNS) stimulant that is used in the treatment of attention deficit hyperactivity disorder (ADHD), narcolepsy, and obesity; it is also used to treat binge eating disorder in the form of its inactive prodrug lisdexamfetamine.
Clonidine and other imidazoline compounds have also been shown to reduce muscle spasms by their central nervous system activity. Tizanidine is perhaps the most thoroughly studied clonidine analog, and is an agonist at α 2-adrenergic receptors, but reduces spasticity at doses that result in significantly less hypotension than clonidine.
