Medications Numerous compounds alleviate the pain from<unk> . Some are specific for certain types of<unk>  while others are general. They include: ;Dynamic mechanical<unk>  - compounds targeting different ion channels; opioids *Mexiletine *Lidocaine (IV/topical) *Tramadol *Morphine (IV) *Alfentanil (IV) *Ketamine (IV) *Methylprednisone (intrathecal) *Adenosine *Glycine antagonist *Desipramine *Venlafaxine *Pregabalin ;Static mechanical<unk>  - sodium channel blockers, opioids * Lidocaine (IV) *Alfentanil (IV) *Adenosine (IV) *Ketamine (IV) *Glycine antagonist *Venlafaxine *Gabapentin (may also be helpful in cold and dynamic<unk> s) ;Cold<unk>  *Lamotrigine *Lidocaine (IV) The list of compounds that can be used to treat<unk>  is even longer than this. For example, many non-steroidal anti-inflammatory drugs, such as naproxen, can inhibit COX-1 and/or COX-2, thus preventing the sensitization of the central nervous system. Another effect of naproxen is the reduction of the responsiveness of mechano- and thermoreceptors to stimuli. Other compounds act on molecules important for the transmission of an action potential from one neuron to another. Examples of these include interfering with receptors for neurotransmitters or the enzymes that remove neurotransmitters not bound to receptors. Endocannabinoids are molecules that can relieve pain by modulating nociceptive neurons. When anandamide, an endocannabinoid, is released, pain sensation is reduced. Anandamide is later transported back to the neurons releasing it using transporter enzymes on the plasma membrane, eventually disinhibiting pain perception. However, this re-uptake can be blocked by AM404, elongating the duration of pain inhibition.
