Medications That Treat Opioid Addiction Do Not Impair Liver Health

diciembre del 2013

A trial of buprenorphine/naloxone (Bup/Nx) showed no evidence that the medicine was associated with liver damage. The drug gave results similar to those of methadone. The study data indicate that although most patients can be treated safely with either methadone or Bup/Nx without major concern for liver injury, clinicians are advised to continue to monitor the liver health of their patients who are on methadone or Bup/Nx therapy.

Potential Pain Medication Targets Peripheral Nerves

septiembre del 2012

Researchers report a significant advance in the search for medications that can suppress pain but avoid opioids’ abuse potential and other undesirable CNS effects. A new compound reduces mouse responses in animal models of neurogenic and chronic inflammatory (e.g., arthritic) pain. The compound, called UB937, enhances the natural pain-killing activity of the neurotransmitter anandamide, and exerts its analgesic effects entirely in peripheral tissues, without entering the brain.

Prenatal drug exposure can have behavioral effects that last well into adulthood, according to two studies of adult monkeys prenatally exposed to cocaine.
