Ketamine for opioid-resistant pain in palliative care. Ketamine is widely used as a third-line drug for cancer pain, when the pain has not responded to opioid in combination with drugs such as nonsteroidal anti-inflammatory drugs, amitriptyline, and gabapentinoids. Published case reports demonstrate that ketamine is used for refractory …Ketamine is actually a pretty straight forward synthesis. It’s the ingredients that are hard to get a hold of, and the large scale it’s produced on make clandestine labs useless. Much easier and more profitable to just divert some from legitimate manufacturers.During attempts to synthesize 2-amino-2- (2-chlorophenyl)-6-hydroxycyclohexanone (6), a ketamine metabolite, an unexpected product, 3- (2-chlorophenyl)-2-hydroxy-2-cyclohexenone (4) was obtained as the major product.
