Free, no-prescription-required access to naloxone injectors and nasal sprays has reduced deaths from opioid overdoses by 11% in some communities, but they only work if someone with the reversal agent is available when a person overdoses. Many times, unfortunately, opioid users are alone when an overdose occurs. Resilient Lifescience Inc. hopes to save those lives, too. The company is developing a wearable patch that monitors vital signs and automatically administers naloxone when needed.

Aphiotx Inc. has identified sulfamoyl benzene derivatives acting as pannexin-1 (PANX1; MRS1) inhibitors reported to be useful for the treatment of opioid withdrawal.

Peking University researchers in collaboration with the NIH have discovered a new biochemical pathway related to a bacterium that eliminates nicotine in the intestine. The findings could lead to new ways to improve nonalcoholic fatty liver disease (NAFLD) in smokers. In addition to the lung and the brain, nicotine can accumulate in the intestine, where the bacteria Bacteroides xylanisolvens could reduce its concentration and the severity of NAFLD. In their study, published in Nature Oct. 19, 2022, the researchers described the enzymes involved in this process and a new undiscovered pathway.
