Pathway Description
Ethylmorphine Action Pathway
Homo sapiens
Drug Action Pathway
Ethylmorphine (also known as codethyline and dionine) is an opioid analgesic. Ethylmorphine can be metabolized to form morphine by cytochrome P450 2D6 (CYP2D6). Morphine can bind the mu-type opioid receptor on central nervous system (CNS) to reduce the pain. Morphine can also bind and inhibit gamma-Aminobutyric acid (GABA) inhibitory interneurons. These interneurons can inhibit the descending pain inhibition pathway; therefore, without the interneurons, pain modulation will go downstream.
