 Preclinical Safety from a translational Perspective As printed within the starting of this chapter, pharmaceutical materia medica or safety assessment is, through and thru, a translational discipline. All aspects of presymptomatic safety activities aim at distinctive potential hazards, predicting and quantifying risks for healthy trial subjects or patients, and, if necessary, assessing appropriate suggests that for eliminating or reducing unacceptable risks. However, there area unit several uncertainties during this approach. For sensible reasons, solely a restricted variety of aspects will be self-addressed in presymptomatic animal and in vitro studies. what is more, significant species variations resulting in changes in biological activity or pharmacokinetic properties further as individual variations in condition to sure effects and compounds augment uncertainties within the risk-assessment method. Thus, any pharmacology risk-assessment method for pharmaceutical or different compounds is often incomplete and related to uncertainties. Such uncertainties area unit paid for by through empirical observation derived safety factors. it's evident from the prevailing incidence of pharmaceutical treatment-related aspect effects that such factors area unit sometimes not adequate to safeguard patients from expected and, significantly, surprising aspect effects. This facet has recently been investigated in an exceedingly thorough analysis of common reasons for drug project attritions in an exceedingly major drug company
