PURPOSE This study investigated the patterns of opioid co-prescription with benzodiazepine and other concomitant medications among opioid users. Opioid dose in each type of co-prescription was also examined. PATIENTS AND METHODS This cross-sectional study was conducted among opioid users receiving concomitant medications at an outpatient tertiary hospital setting in Malaysia. Opioid prescript...

BACKGROUND The analgesic efficacy and side effect profile of intravenous parecoxib, a novel cyclooxygenase type-2 (COX-2) inhibitor, was assessed in a double-blinded, placebo-controlled study involving patients undergoing major gynecologic surgical procedures. METHODS After Institutional Review Board approval, 60 consenting women, American Society of Anesthesiologists (ASA) physical status I-...

abstract background and objective: pain relief during labour is an important determinant of a women’s birth experience. there are numerous pain relief techniques which can be used either with or without pain medication. the aim of our study was to compare the effect of remifentanil alone and its effect in pain relief while using with ketamine during labour. methods: after obtaining informed con...

the catastrophic effects of opioids use on public health and the economy are documented clearly in numerous studies. repeated morphine administration can lead to either a decrease (tolerance) or an increase (sensitization) in its behavioral and rewarding effects. morphine-induced sensitization is a major problem and plays an important role in abuse of the opioid drugs. studies reported that mor...

BACKGROUND Electroacupuncture (EA) is believed to modulate the pain pathway via the release of endogenous opioid substances and stimulation of descending pain inhibitory pathways. In this study, the use of intraoperative 2 Hertz EA stimulation is investigated to determine any opioid-sparing effect and reduction of postoperative nausea and vomiting (PONV) in patients undergoing gynaecological su...

Glutamate neurotransmission plays an important role in the processing of pain and in chronic opioid-induced neural and behavioral plasticity, such as opioid withdrawal and opioid dependence. -Opioid receptors also have been implicated in acute opioid modulation of pain and chronic opioid-induced plasticity, both of which are primarily mediated by -opioid receptors. Using whole-cell patch clamp ...

OBJECTIVE After prolonged opioid exposure, children develop opioid-induced hyperalgesia, tolerance, and withdrawal. Strategies for prevention and management should be based on the mechanisms of opioid tolerance and withdrawal. PATIENTS AND METHODS Relevant manuscripts published in the English language were searched in Medline by using search terms "opioid," "opiate," "sedation," "analgesia," ...

Many states have implemented limitations on opioid prescriptions for patients with acute pain. Few studies investigated relationships between prescribing restrictions and clinical outcomes. We assessed effects of pain restriction laws trends in opioid-related overdose deaths among that these policies. evaluated the state three outcomes: all-opioid, prescription opioid, heroin-related deaths. as...
