MOA: Tramadol
µ agonist blocking NE and 5-HT reuptake
MOA: Ketamine
NDMA-antagonist creating trance-like state
MOA: Dexmedetomidine
a2-adrenergic agonist causing sedation
MOA: Clonidine
a2-adrenergic agonist blocking pain signals from periphery to CNS
MOA: Ziconotide
N-type voltage sensitive Ca-channel antagonist on afferent neurons in dorsal horn of spinal cord preventing pain signal from periphery to CNS
