Administering naloxone hydrochloride (naloxone) during an opioid overdose reverses the overdose and can prevent death. Although typically delivered via intramuscular or intravenous injection, naloxone may be delivered via intranasal spray device. In August 2006, the Boston Public Health Commission passed a public health regulation that authorized an opioid overdose prevention program that inclu...
AIMS Traditionally, the opiate antagonist naloxone has been administered parenterally; however, intranasal (i.n.) administration has the potential to reduce the risk of needlestick injury. This is important when working with populations known to have a high prevalence of blood-borne viruses. Preliminary research suggests that i.n. administration might be effective, but suboptimal naloxone solut...
In October 2002, the U.S. Food and Drug Administration approved buprenorphine-naloxone (Suboxone) sublingual tablets as an opioid dependence treatment available for use outside traditionally licensed opioid treatment programs. The NIDA Center for Clinical Trials Network (CTN) sponsored two clinical trials assessing buprenorphine-naloxone for short-term opioid detoxification. These trials provid...
BACKGROUND The objective of this investigation was to examine the ability of the opioid antagonist naloxone to reverse respiratory depression produced by the mu-opioid analgesic, buprenorphine, in healthy volunteers. The studies were designed in light of the claims that buprenorphine is relatively resistant to the effects of naloxone. METHODS In a first attempt, the effect of an intravenous b...
Estrogen promotes the growth of breast cancer via estrogen receptors (ER). Earlier studies showed that the opioid receptor antagonist naloxone inhibits MCF-7 breast cancer growth in mice. We examined the cellular and molecular mechanism of naloxone antagonism of ERalpha activity in human MCF-7 cells. Naloxone (100 nmol/L) inhibited 17beta-estradiol (E2)-induced (10 nmol/L) MCF-7 cell proliferat...
UNLABELLED Previous work demonstrated that both the opioid antagonist (-)-naloxone and the non-opioid (+)-naloxone inhibit toll-like receptor 4 (TLR4) signaling and reverse neuropathic pain expressed shortly after chronic constriction injury. The present studies reveal that the TLR4 contributes to neuropathic pain in another major model (spinal nerve ligation) and to long established (2-4 month...
There is a need to develop dosage forms suitable for children improve drug treatment. Extemporaneous compounding of drugs one way meet these needs. However, excipients generally considered as safe in adults may not be appropriate intended children. The aim was optimize the composition two pediatric liquid preparations by substituting paraben microbiological preservative and ethanol solubilizer,...
Opiate users' knowledge about overdose prevention and naloxone in New York City: a focus group study
BACKGROUND Drug-induced and drug-related deaths have been increasing for the past decade throughout the US. In NYC, drug overdose accounts for nearly 900 deaths per year, a figure that exceeds the number of deaths each year from homicide. Naloxone, a highly effective opiate antagonist, has for decades been used by doctors and paramedics during emergency resuscitation after an opiate overdose. F...
Naloxone, an opiate antagonist that can avert opiate overdose mortality, has only recently been prescribed to drug users in a few jurisdictions (Chicago, Baltimore, New Mexico, New York City, and San Francisco) in the United States. This report summarizes the first systematic evaluation of large-scale naloxone distribution among injection drug users (IDUs) in the United States. In 2005, we cond...
Two experiments were conducted with the opioid antagonist naloxone to determine the effect of opioid receptor blockade on hormone secretion in postpartum beef cows. In Exp. 1, nine anestrous postpartum beef cows were used to measure the effect of naloxone on serum luteinizing hormone (LH), cortisol and prolactin concentrations. Cows received either saline (n = 4) or 200 mg naloxone in saline (n...
