Have the Findings from Clinical Risk Prediction and Trials Any Key Messages for Safety Pharmacology?
Anti-arrhythmic drugs are a mainstay in the management of symptoms related to arrhythmias, and are adjuncts in prevention and treatment of life-threatening ventricular arrhythmias. However, they also have the potential for pro-arrhythmia and thus the prediction of arrhythmia predisposition and drug response are critical issues. Clinical trials are the latter stages in the safety testing and eff...
Industry is increasingly adopting software and system safety standards that mandate the use of hazard logs in the development and operation of safety critical systems. Hazard logs are used to record and track the results of hazard analysis and risk assessment throughout the lifecycle of the system. Even relatively simple systems give rise to large amounts of information and the need for tools t...
