Cannabinoids provide a potential approach to pain management with a novel therapeutic target and mechanism. Chronic pain often requires a polypharmaceutical approach to management, and cannabinoids are a potential addition to the arsenal of treatment options.

Oral chemotherapies are more often used on label than off label in current practice at our community cancer center. The majority of off-label use of oral oncolytics in this study was supported by NCCN guideline recommendations.

Oxycodone and oxycodone-containing analgesics are often used for the relief of pain. In the presence of renal dysfunction, the half-life of oxycodone and metabolites can be prolonged. We describe the case of a 41-year-old chronic hemodialysis patient who received multiple doses of oxycodone/acetaminophen resulting in accumulation of the medication and consequent lethargy, hypotension and respiratory depression. These adverse effects were reversed with multiple bolus doses of naloxone, followed by a continuous infusion administered for 45 hours. Utilizing the Naranjo probability scale, the patient had a "probable" adverse drug reaction to the oxycodone. Oxycodone should be used with caution in patients with chronic renal failure.

Chronic pain is a major health problem in the United States affecting 50 to 75 million Americans. The extent of pain encountered with chronic disease states may impact an individual's quality of life. Morphine is the drug of choice for severe pain. The primary purpose of the study was to determine analgesic response with the use of topical morphine to control chronic pain in a series of patients with arthritis pain. The second purpose was to detect the presence of morphine in the urine following topical administration and subsequently conclude that there had been systemic absorption of the drug. Three patients were prescribed topical morphine for chronic pain and were followed over the course of several weeks. Each patient was instructed to record the date and time of the topical morphine applications. When each patient had achieved a satisfactory level of pain control a 24-hour urine collection was obtained and taken to a laboratory for analysis. All patients reported a satisfactory degree of pain relief following topical application of morphine. The urine analysis confirmed the presence of morphine in the 24-hour samples. This analysis confirms systemic absorption of the morphine across intact skin; however the results cannot be used to quantify the degree of systemic absorption. Results of the study indicate that the use of topical morphine is effective in controlling chronic pain and topical morphine is absorbed systemically in the body.

The pros and cons of using opioid analgesics to help manage pain in patient with a history of substance abuse are presented. Topics discussed include ethical constructs, efficacy, and safety relating to the use of opioids in patients with substance abuse histories.
