Salbutamol, a Short Acting Beta-2 Agonist, Reduces Risk and Improves Prognosis of Prostate Cancer.

Beta-blockers, a class of drugs commonly used to manage blood pressure, have been the subject of research regarding their relationship to prostate cancer (PC) risk, prognosis, and treatment. Beta-blockers reduce risk and improve the prognosis of PC. Perioperative use of a nonselective beta-blocker improves outcomes after radical prostatectomy. However, a related class of drugs, beta-2 adrenergic agonists, has received little attention in PC. We studied the relationship of the beta-2 adrenergic agonist salbutamol to PC risk and survival. We analyzed Food and Drug Administration MedWatch data to determine whether salbutamol could influence the risk of PC. We used UK Biobank data to assess the effect of salbutamol on PC survival. Salbutamol significantly reduces PC risk, proportional reporting ratio, and 95% CI (lower bound; upper bound): 0.131 (0.11; 0.155) and improves prognosis. Mean survival was 7.35 years for subjects not taking salbutamol, and 10.5 years for subjects taking salbutamol (P = 0.041, log-rank test. To adjust for the effect of age, we performed proportional hazards regression, survival time-dependent variable, age, and salbutamol use independent variables. Salbutamol use was significantly related to survival time (P = 0.016) and independent of the significant effect of age (P < 0.001). We found a lower proportion of PCs in salbutamol-treated people, but we have not demonstrated that PC risk is reduced (there is no proof of causality). There is no causality relationship between salbutamol and the survival of patients with PC treated with salbutamol versus those not treated with the drug. Yet, there is a trend in favor of salbutamol-treated patient survival. Therefore, salbutamol and other beta-adrenergic agonists might represent a new class of drugs for the treatment of PC.

FDA Evaluating Possible Serious Risks From Umbralisib.

Initial clinical trial data for umbralisib (Ukoniq), a drug currently approved to treat relapsed or refractory marginal zone lymphoma and relapsed or refractory follicular lymphoma, indicate that umbralisib may increase the risk of death or serious adverse effects when given with a specific monoclonal antibody to treat chronic lymphocytic leukemia.Patients receiving umbralisib to treat lymphomas should be evaluated closely for adverse effects. Nurses and other health care providers should report any of these adverse effects to the Food and Drug Administration's MedWatch program.

Serious Cardiovascular Adverse Events Reported with Intravenous Sedatives: A Retrospective Analysis of the MedWatch Adverse Event Reporting System.

BackgroundSerious cardiovascular adverse events (SCAEs) associated with intravenous sedatives remain poorly characterized.ObjectiveThe objective of this study was to compare SCAE incidence, types, and mortality between intravenous benzodiazepines (i.e., diazepam, lorazepam, and midazolam), dexmedetomidine, and propofol in the USA over 8 years regardless of the clinical setting where it was administered.MethodsThe Food and Drug Administration’s MedWatch Adverse Event Reporting System was searched between 2004 and 2011 using the Evidex® platform from Advera Health Analytics, Inc. to identify all reports that included one or more of ten different SCAEs (package insert incidence ≥ 1%) and where an intravenous benzodiazepine, dexmedetomidine, or propofol was the primary suspected drug.ResultsAmong the 2326 Food and Drug Administration’s MedWatch Adverse Event Reporting System cases reported, 394 (16.9%) were related to a SCAE. The presence of a SCAE (vs. a non-SCAE) is associated with higher mortality (34 vs. 8%, p < 0.001). The percentage of cases with one or more SCAE, the case mortality rate (%), and the incidence of each SCAE (per 106 days of sedative exposure), respectively, were benzodiazepines (14, 26, 13) [diazepam (13, 23, 31); lorazepam (15, 43, 14); midazolam (14, 20, 11)]; dexmedetomidine (40, 15, 13); and propofol (17, 39, 7). Propofol (vs. either a benzodiazepine or dexmedetomidine) was associated with more total SCAEs (268 vs. 126, p < 0.001) but a lower incidence (per 106 days of sedative exposure) of SCAE (7 vs. 13, p = 0.0001) and cardiac arrest [6.3 (benzodiazepine) vs. 6.7 (dexmedetomidine) vs. 1.4 (propofol), p < 0.0001].ConclusionsSerious cardiac adverse events account for nearly one-fifth of intravenous sedative Food and Drug Administration’s MedWatch Adverse Event Reporting System reports. These SCAEs appear to be associated with greater mortality than non-cardiac serious adverse events. Serious cardiac events may be more prevalent with either benzodiazepines or dexmedetomidine than propofol.Electronic supplementary materialThe online version of this article (10.1007/s40801-019-00161-y) contains supplementary material, which is available to authorized users.

Summaries of Safety Labeling Changes Approved by the FDA: Boxed Warnings Highlights.

As part of the US Food and Drug Administration's MedWatch program, safety labeling changes are reviewed and compiled monthly for drugs and therapeutic biologics where important changes have been made to the safety information. Boxed warnings (http://www.fda.gov/downloads/Drugs/GuidanceComplianceRegulatoryInformation/Guidances/ucm075096.pdf) are ordinarily used to highlight either adverse reactions so serious in proportion to the potential benefit from the drug that it is essential that it be considered in assessing the risks and benefits of using the drugs or serious adverse reactions that can be prevented/reduced in frequency or severity by appropriate use of the drug; or FDA approved the drug with restrictions to ensure safe use because FDA concluded that the drug can be safely used only if distribution or use is restricted. There were 10 revised boxed warnings and 1 drug class change from April through June 2016.
