BACKGROUND The study aimed to investigate the analgesic effect of a combination of intravenous flurbiprofen axetil and opioids, and evaluate the relationship between refractory pain relief and plasma β-endorphin levels in cancer patients. MATERIALS AND METHODS A total of 120 cancer patients was randomly divided into two groups, 60 patients took orally morphine sulfate sustained-release tablet...

Patients with intravenous heroin addiction are prone to recurrent infections and at times these infections are fatal. We evaluated the effect of morphine on the apoptosis of Jurkat cells and freshly isolated human T lymphocytes. Morphine promoted apoptosis of both the Jurkat cells and the freshly isolated T lymphocytes in a dose-dependent manner. DAGO, a specific mu receptor agonist, also promo...

OBJECTIVES To evaluate and compare the effects of preoperative oral pregabalin and perioperative intravenous lidocaine infusion on postoperative morphine requirement, adverse effects, patients' satisfaction, mobilization, time to first defecation and time to discharge in patients undergoing laparotomy. METHODS Eighty patients (18 to 65 years of age) undergoing elective laparotomy were randoml...

BACKGROUND Respiratory depression, a potentially fatal side-effect of opioid-overdose, may be reversed by timely administration of an opioid antagonist, such as naloxone or naltrexone. Tampering with a formulation of morphine sulfate and sequestered naltrexone hydrochloride extended release capsules (MS-sNT) releases both the opioid morphine and the antagonist naltrexone. A study in recreationa...

Effectively managing pain is known to be problematic in the emergency department (ED) with up to 43% of patients with oligoanalgesia [1–3]. Opioids alone are commonly inadequate at controlling acute and acute on chronic pain in the ED [4–6]. Furthermore, using higher doses or more potent opioids may be challenging in some patients because of the risk of adverse effects such as somnolence, respi...

BACKGROUND Despite the fact that numerous medications have been introduced to treat renal colic, none has been proven to relieve the pain rapidly and thoroughly. In this study, we aimed at comparing the effects of intravenous lidocaine versus intravenous morphine in patients suffering from renal colic. METHODS In a prospective randomized double-blind clinical trial performed in the emergency ...

The present study, conducted as part of the development of a buprenorphine/naloxone combination product, was designed to evaluate the individual and combined effects of intravenously administered buprenorphine and naloxone. This in-patient trial used a randomized, double-blind, crossover design. Ten opioid-dependent male subjects were stabilized and maintained on morphine, 15 mg given intramusc...

To see whether continuous intravenous infusion of opiates provides more effective postoperative relief of pain than conventional intramuscular injection these regimens were compared in a prospective double blind trial. Thirty patients undergoing elective cholecystectomy were allocated randomly to receive an infusion of morphine or an infusion of placebo (control group) for 24 hours. Both groups...
