FIGURE 1 Activating the Transient Receptor Potential Vanilloid 1 and Cannabinoid 1 Receptors Acetaminophen is first metabolized to p -aminophenol, which easily crosses the blood-brain barrier and is converted to AM404 by fatty acid amide hydrolase ( N -acetyl- p -benzoquinoneimine (NAPQI), which also appears to produce analgesia by activating transient receptor potential ankyrin 1 receptors ( Similar to the brain, it is also known that the spinal cord, especially SG neurons, is critical to pain pathways, and modulates nociceptive transmission via primary afferent A- and C-fibers ( c-fos -positive immunoreactivity induced by non-noxious stimulation of the spinal cord in a rat model of neuropathic or inflammatory pain, and these responses are inhibited by TRPV1 or CB1 receptor antagonists ( in vivo and in vitro whole-cell patch-clamp recordings with nave rats ( in vivo and in vitro whole-cell patch-clamp recordings of SG neurons in the spinal cord dorsal horn and recorded the excitatory post-synaptic currents (EPSCs)
