Sugar pills may well be Therapy for chronic Pain in future
Are you surprised - but its true, Sugar pills may be Therapy for Chronic Pain in the future.
According to a new research, sugar pills may reduce pain as effectively as any powerful drug in certain chronic pain patients based on their brain anatomy and psychology. The Northwestern Medicine scientists have shown that they can reliably predict which chronic pain patients will respond to a sugar placebo pill based on the patients' brain anatomy and psychological characteristics. The study has been published in Nature Communications.
About 60 chronic back pain patients were randomized into two arms of the study. In one arm, subjects didn't know if they got the drug or the placebo. Researchers didn't study the people who got the real drug. The other study arm included people who came to the clinic but didn't get a placebo or drug. They were in the control group.
The individuals whose pain decreased as a result of the sugar pill had a similar brain anatomy and psychological traits. The right side of their emotional brain was larger than the left, and they had a larger cortical sensory area than people who were not responsive to the placebo. The chronic pain placebo responders also were emotionally self-aware, sensitive to painful situations and mindful of their environment.
Key findings of Study are-
- Doctors should consider treating chronic pain patients with sugar pills
- Placebo pills relieve pain as effectively as drugs for half of the chronic pain patients
- Pain reduced by 30 per cent
- No need to fool patients, the brain is primed to respond
- The finding can result in vast cost savings for patients, the healthcare system
"Their brain is already tuned to respond," said senior study author A. Vania Apkarian, professor of physiology at Northwestern University Feinberg School of Medicine. "They have the appropriate psychology and biology that puts them in a cognitive state that as soon as you say, 'this may make your pain better,' their pain gets better."
There's no need to fool the patient, Apkarian said.
"You can tell them, 'I'm giving you a drug that has no physiological effect but your brain will respond to it,'" he said. "You don't need to hide it. There is a biology behind the placebo response."
The findings have three potential benefits:
- Prescribing non-active drugs rather than active drugs. "It's much better to give someone a non-active drug rather than an active drug and get the same result," Apkarian said. "Most pharmacological treatments have long-term adverse effects or addictive properties. Placebo becomes as good an option for treatment as any drug we have on the market."
- Eliminating the placebo effect from drug trials. "Drug trials would need to recruit fewer people, and identifying the physiological effects would be much easier," Apkarian said. "You've taken away a big component of noise in the study."
- Reduced health care costs. A sugar pill prescription for chronic pain patients would result in vast cost savings for patients and the healthcare system, Apkarian said.
"Clinicians who are treating chronic pain patients should seriously consider that some will get as good a response to a sugar pill as any other drug," Apkarian said. "They should use it and see the outcome. This opens up a whole new field."
