Expert opinion on drug safety
-
Pain management with opioids is a fundamental element of palliative medicine. Since the risks of chronic opioid therapy have emerged, a reassessment of these risks in the setting of palliative care is warranted. ⋯ Palliation of severe pain at the end of life is probably the most widely accepted indication for chronic opioid therapy. At increased doses, adverse effects of opioids may limit or interfere with the benefits of treatment. Careful screening and follow-up will allow risk factors to be recognized and addressed when possible. The use of adjunctive treatments for pain may reduce opioid requirements and yield better outcomes.

Randomized Controlled TrialRadium-223 dichloride for the treatment of bone metastatic castration-resistant prostate cancer: an evaluation of its safety.
Approximately 10 - 20% of prostate cancer cases ultimately progress to castration-resistant prostate cancer (CRPC), for which there is a poor prognosis and a therapeutic need. Radium-223 dichloride (radium-223 [Xofigo]) is a first-in-class α-emitting radiopharmaceutical shown to significantly prolong overall survival in patients with CRPC with symptomatic bone metastases and no visceral metastases. Current treatment guidelines recommended it in both pre- and post-docetaxel settings. ⋯ The pronounced efficacy and safety profile of radium-223 positions it as a valuable new therapeutic tool in the CRPC armamentarium. Its novel mechanism of action underlies low rates of hematologic adverse events. Radium-223 treatment will become common in the majority of pre-docetaxel symptomatic CRPC cases, as it has proved to be highly efficient with few safety concerns earlier in the course of disease.
