Pain Relief: Unique Derivatives of Ibogaine Alleviate Both Acute and Chronic Pain Symptoms

Physiology May 1, 2024 Sanjit Dey, Tuhin Bhattacharya, Surajit Sinha 1 citation

Iboga derivatives, particularly iboga-alcohol, reduce pain and inflammation in rodent models of acute and chronic pain without causing psychedelic effects. In formalin-induced acute pain, the compounds decreased paw swelling, reversed reduced tail flick latency, and improved locomotor activity. They also reduced inflammatory markers such as Substance P, CGRP, COX-2, and p65 nuclear translocation, and lowered serum IL-6 and TNF-α levels. Iboga-alcohol inhibited mechanical allodynia and heat hyperalgesia in chronic pain and restored impaired motor activity. The derivatives reversed BDNF depletion and modulated GDNF elevation. These findings suggest the compounds are promising candidates for non-psychedelic pain treatments.

Effect of Intravenous Delivery of N,N Dimethyltryptamine on Sleep-Wake States in Rat

Physiology May 1, 2024 Rachel Summerfield, Trent Groenhout, Tiecheng Liu et al.

Intravenous DMT, a psychedelic, increases wakefulness and reduces slow-wave sleep in rats during the first three hours after administration, with a delay in the onset of rapid eye movement sleep. Low (3.75 mg/kg) and high (7.5 mg/kg) doses both produced these effects, while time spent in REM sleep during the light period was unaffected. The findings align with previous reports on serotonergic psychedelics and wakefulness.
