According to an international group of researchers including a team from the University of Liverpool, patients experience 30% fewer side effects when medication doses are tailored to their DNA.
Overdose deaths involving buprenorphine did not proportionally increase with new flexibilities in prescribing
The proportion of opioid overdose deaths involving buprenorphine, a medication used to treat opioid use disorder, did not increase in the months after prescribing flexibilities were put in place during the COVID-19 pandemic, according to a new study.
Lab lights way to simple chemical synthesis
Inexpensive iron salts are a key to simplifying the manufacture of essential precursors for drugs and other chemicals, according to scientists at Rice University.

Scientists from St. Jude Children’s Research Hospital performed the largest study yet examining drug sensitivity in childhood acute lymphoblastic leukemia across genomic subtypes and its association with treatment response.
New drug offers hope for people with hand osteoarthritis
Tonia Vincent, Professor of Musculoskeletal Biology & Honorary Rheumatologist at Oxford’s Nuffield Department of Orthopaedics, Rheumatology and Musculoskeletal Sciences (NDORMS), said: ‘Hand osteoarthritis is a common and debilitating medical condition that affects mainly women, especially around the time of the menopause.
Newly identified neuromarker reveals clues about drug and food craving
Craving is known to be a key factor in substance use disorders and can increase the likelihood of future drug use or relapse.
Space and time influence G-protein coupled receptor interactions
By simulating molecular dynamics, scientists from St. Jude Children’s Research Hospital revealed how the selectivity or promiscuity of GPCR coupling relies on the location and duration of intermolecular interactions.

The life expectancy of women is significantly higher than that of men.
With High Costs and Similar Benefits, Use of New Neurology Drugs Is Low
A number of new neurologic medications for diseases like multiple sclerosis (MS), Parkinson’s disease and migraine have received U.S. Food and Drug Administration (FDA) approval over the past decade. However, with most having higher out-of-pocket costs and benefits similar to existing, less expensive drugs, only a small percentage of people with neurologic conditions are being treated with these new drugs, according to a study funded by the American Academy of Neurology and published in the November 30, 2022, online issue of Neurology®, the medical journal of the American Academy of Neurology.
