Type A: augmented pharmacological effects, which are dose-dependent and predictable [5]; Type A reactions, which constitute approximately 80% of adverse drug reactions, are usually a consequence of the drug's primary pharmacological effect (e.g., bleeding when using the anticoagulant warfarin) or a low therapeutic index of the drug (e.g., nausea from digoxin), and they are therefore predictable.
CDR is one means of establishing the validity and benefits of medication in treating specific conditions [1] as well as any adverse drug reactions.The Food and Drug Administration of the United States lists positive dechallenge reactions (an adverse event which disappears on withdrawal of the medication) as well as negative (an adverse event which continues after withdrawal), as well as ...
Many developed countries set up their pharmacovigilance programs following the Thalidomide scandal in the 1960s. [2] India set up its program in the 1980s. [2] This general concept of drug safety monitoring went through different forms, but the Central Drugs Standard Control Organisation established the present Pharmacovigilance Program of India in 2010.

A risk management plan is a documented plan that describes the risks (adverse drug reactions and potential adverse reactions) associated with the use of a drug and how they are being handled (warning on drug label or on packet inserts of possible side effects which if observed should cause the patient to inform/see his physician and/or ...
The black triangle also highlights the need for surveillance of any Adverse Drug Reactions (ADRs) that might arise from the use of a new medication. The Medicines and Healthcare products Regulatory Agency (MHRA) encourage anyone to voluntarily report ADRs (however minor) via the Yellow Card Scheme to gather more information and gain more ...
The Naranjo algorithm, Naranjo Scale, or Naranjo Nomogram is a questionnaire designed by Naranjo et al. for determining the likelihood of whether an adverse drug reaction (ADR) is actually due to the drug rather than the result of other factors. Probability is assigned via a score termed definite, probable, possible or doubtful.
Further, the FDA does not receive all adverse event reports that occur with a product. Many factors can influence whether or not an event will be reported, such as the time a product has been marketed and publicity about an event. Therefore, FAERS cannot be used to calculate the incidence of an adverse event in the U.S. population.
EudraVigilance (European Union Drug Regulating Authorities Pharmacovigilance) is the European data processing network and management system for reporting and evaluation of suspected adverse reactions to medicines or devices which have received marketing authorisation or are actively being studied in clinical trials in the European Economic Area (EEA).
