Question

Effect of drug theray on endothelial progenitor cells

Answer 1

Therapeutic effect refers to the responses(s) after a treatment of any kind, the results of which are judged to be useful or favorable.[1][2][3] This is true whether the result was expected, unexpected, or even an unintended consequence. An adverse effect(including nocebo) is the converse and refers to harmful or undesired responses(s). What constitutes a therapeutic effect versus a side effect is a matter of both the nature of the situation and the goals of treatment. No inherent difference separates therapeutic and undesired side effects; both responses are behavioral/physiologic changes that occur as a response to the treatment strategy or agent.[2]
