Patients with cancer sometimes are admitted to the emergency room due to severe pain. Despite the fact that morphine's hydrophilicity can delay its peak effects after intravenous administration up to 30 minutes, it is still the most commonly used…

Bisphosphonates have become standard treatment in management of malignancy-induced hypercalcemia and malignant bone pain. One obstacle to the routine use of bisphosphonates in palliative patients is that oral bisphosphonates have low bioavailability…

Opioids are used increasingly for chronic non-cancer pain. Controversy exists about their effectiveness and safety with long-term use. We analysed available randomised, placebo-controlled trials of WHO step 3 opioids for efficacy and safety in…

This article reviews the literature pertaining to the metabolism of several of the commonly used opioids, and the known activity of their metabolites. The effect of renal failure on the pharmacokinetics of these drugs and metabolites is then…

BACKGROUND: Bisphosphonates form part of standard therapy for hypercalcemia and the prevention of skeletal events in some cancers. However, the role of bisphosphonates in pain relief for bony metastases remains uncertain. OBJECTIVES: To determine the…

CONTEXT: 1',1'dimethylheptyl-Delta8-tetrahydrocannabinol-11-oic acid (CT-3), a potent analog of THC-11-oic acid, produces marked antiallodynic and analgesic effects in animals without evoking the typical effects described in models of cannabinoids.…

Critically ill children are treated with opioid medication in an attempt to decrease stress and alleviate pain during prolonged pediatric intensive care. This treatment plan places children at risk for opioid dependency. Once dependent, children need…

Tramadol (Ultram, Ortho-McNeil Pharmaceutical, Inc., Raritan, NJ) is considered a Step 2 analgesic under the World Health Organization's guidelines for the treatment of patients with cancer pain. It is a centrally acting analgesic that has affinity…

OBJECTIVES: Professional societies, ethics institutes, and the courts have recommended principles to guide the care of children with life-threatening conditions; however, little is known about the degree to which pediatric care providers are aware of…

Over twelve thousand children are diagnosed each year with cancer, and approximately 2200 children die each year from the disease. A percentage of these patients experiences escalating and intractable distress with symptoms that include pain,…

Methadone, although having been available for approximately half a century, is now receiving increasing attention in the management of chronic pain. This is due to recent research showing that methadone exhibits at least three different mechanisms of…

Topical morphine has been used on open wounds for pain management, but has a variable duration of action not suitable for palliative dressing changes. The objective of this study is to find an opioid and delivery method that would provide…

Development of analgesic tolerance and withdrawal-induced pain enhancement present serious difficulties for the use of opioids for pain control. Although neuronal mechanisms to account for these phenomena have been sought for many decades, their…

The neuropeptide nociceptin/orphanin FQ (N/OFQ) is the endogenous ligand for the opioid-like receptor ORL-1 and is thought to be involved in pain transmission and modulation. Human studies have not yet defined its role in pain patients. The aims of…

Ingestions of opioid analgesics by children may lead to significant toxicity as a result of depression of the respiratory and central nervous systems. A review of the medical literature was performed to determine whether low doses of opioids are…

OBJECTIVES: To describe the potential for interaction between opioids and serotonergic antidepressants leading to the development of serotonin syndrome (SS), mechanism of the interaction, and the spectrum of SS in elderly residents of a long-term…

BACKGROUND: The current study was conducted to assess the safety and tolerability of a transdermal fentanyl delivery system for the relief of chronic pain in a pediatric population, and also to validate titration recommendations and conversion to…

OBJECTIVE: Our goal was to determine which of 3 analgesics, acetaminophen, ibuprofen, or codeine, given as a single dose, provides the most efficacious analgesia for children presenting to the emergency department with pain from acute musculoskeletal…

INTRODUCTION: Opioid-related mortality appears to be increasing in Canada. We examined the true extent of the problem and the impact of the introduction of long-acting oxycodone. METHODS: We examined trends in the prescribing of opioid analgesics in…

This article surveys worldwide medical, ethical, and legal trends and initiatives related to the concept of pain management as a human right. This concept recently gained momentum with the 2004 European Federation of International Association for the…

OBJECTIVE: Review and analyze the evidence base comprising methadone conversion methods and associated dosing ratios for the treatment of pain. DESIGN: Systematic review. METHODS: Clinical trials and retrospective analyses, case series, and case…

The management of pain in children with life-limiting illnesses is complex and unfortunately not often done effectively. Pain is a multidimensional symptom that can overshadow all other experiences of both the child and family. This article focuses…

Throughout the long history of opioid drug use by humans, it has been known that opioids are powerful analgesics, but they can cause addiction. It has also been observed, and is now substantiated by multiple reports and studies, that during opioid…
