The Common Terminology Criteria for Adverse Events (CTCAE), [1] formerly called the Common Toxicity Criteria (CTC or NCI-CTC), are a set of criteria for the standardized classification of adverse events of drugs and treatment used in cancer therapy. The CTCAE system is a product of the US National Cancer Institute (NCI).
Adverse event coding is the process by which information from an AE reporter, called the "verbatim", is coded using standardized terminology from a medical coding dictionary, such as MedDRA (the most commonly used medical coding dictionary). The purpose of medical coding is to convert adverse event information into terminology that can be ...
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.
Adverse effects, like therapeutic effects of drugs, are a function of dosage or drug levels at the target organs, so they may be avoided or decreased by means of careful and precise pharmacokinetics, the change of drug levels in the organism in function of time after administration. Adverse effects may also be caused by drug interaction. This ...
The Coding Symbols for a Thesaurus of Adverse Reaction Terms (COSTART) was developed by the United States Food and Drug Administration (FDA) for the coding, filing and retrieving of post-marketing adverse reaction reports. [1] COSTART provides a method to deal with the variation in vocabulary used by those who submit adverse event reports to ...
Adverse events categorized as "serious" (results in death, illness requiring hospitalization, events deemed life-threatening, results in persistent or significant incapacity, a congenital anomaly or medically important condition) must be reported to the regulatory authorities immediately, whereas non-serious adverse events are merely documented ...
A late effect can be caused directly by the earlier condition, or indirectly by the treatment for the earlier condition. Some late effects can occur decades later. Historically, late effects have been very difficult to connect with their causes, but as survival and life span have increased and "follow up" has become standard practice, these ...
In drug development, serious adverse event (SAE) is defined as any untoward medical occurrence during a human drug trial that at any dose Results in death; Is life-threatening; Requires inpatient hospitalization or causes prolongation of existing hospitalization; Results in persistent or significant disability/incapacity
