As such, pharmacovigilance heavily focuses on adverse drug reactions (ADR), which are defined as any response to a drug which is noxious and unintended. That definition includes lack of efficacy: that means that the ...

It introduced a requirement for drug manufacturers to provide proof of the effectiveness and safety of their drugs before approval, [1] [2] required drug advertising to disclose accurate information about side effects, and stopped cheap generic drugs being marketed ...
This phase is designed to assess the safety (pharmacovigilance), tolerability, pharmacokinetics, and pharmacodynamics of a drug. Phase I trials normally include dose-ranging , also called dose escalation studies, so that the best and safest dose can be found and to discover the point at which a compound is too poisonous to administer.

Postmarketing surveillance (PMS), also known as post market surveillance, is the practice of monitoring the safety of a pharmaceutical drug or medical device after it has been released on the market and is an important part of the science of pharmacovigilance.
It also provides assurance of the safety and efficacy of the newly developed compounds. GCP guidelines include standards on how clinical trials should be conducted, define the roles and responsibilities of institutional review boards, clinical research investigators, clinical trial sponsors, and monitors.
Because of the lack of these data and uncertainty about methods for synthesising them, individuals conducting systematic reviews and meta-analyses of therapeutic interventions often unknowingly overemphasise health benefit. [5] To balance the overemphasis on benefit, scholars have called for more complete reporting of harm from clinical trials. [6]
