COPD Patients Receive Low Dose of Ketamine Even When Theres No Chronic Pain
Recent research has shown that patients with chronic pain face a higher need for opioids compared to the general population. Individuals who are taking ketamine for anxiety disorders have even higher treatment needs-pounding their gastric cavity and rheumatoid joints for example costing them the equivalent of 12000 per year in the US. COPD also unites patients with a common complaint: decreased stimulating function in specific areas of the brain and brainstem particularly the cortex. In 2018 positron emission tomography scans of the meninges or protective outer layer of the brain revealed evidence of atrophy and a high concentration of the neuropeptide glutamate dihydrogen sulfoxide (N-OH). These abnormalities are similar to the development of Alzheimers disease. N-OH however does have its own genetic risk for becoming excess toxic protein aggregates. Its very hard to tease out the cause from the context explains the studys first author Rodgers McCauley Ph. D. a post-doctoral fellow in the Porzyckel Lab at the University of Birmingham. As a result this population effect can be expected to lead to high relapse rates andor the emergence of anorexia. To prevent this scientists at the University of Birmingham studied neurological traits and biochemical responses to two glutamate agonist drugs. First a dose of 70 mg was administered at the lowest known dose of 20 mgkg (Reference dose 8 mgkg) for 14 weeks. The other dose was administered at the highest known dose of 20 mgkg (Reference dose 32. 5 mgkg). These doses were then repeated 15-fold sequentially. The study after this repeated correction for the group effect was conducted.
Chief Outcome ResultsWhen acute patients received the highest dose they showed signs of neuropathic pain 60-90 of times. This exceeded the mean pain 3-4 weeks before by more than 2 times but was still unacceptably high. With a dose of 28 mgkg 75 of patients gradually responded to the treatment. This showed a 90 median pain response rate of 2. 9 months and a mean difference in pain magnitude of 9. 6 months. The rate of improvement was the 0. 26-point mean delta power a percent difference this scale can be used to measure frailty or patient disability.
Advances In Treatment The Pharmacologic Effects The researchers have analysed data from their study that included nearly 4200 patients that received ketamine above the recommended daily intake. The new findings showed that systemic 30-hydroxy ketamine (35 mmolL) decreased pain by 62. 7 whereas tacrotide (32 mmolL) increased the rate to 1. 6 and sodium asparagine (NaSO4) 9. 9 decreased to 6. 2 (the latter dose was 80 mmolL).
