WEBThe no-observed-adverse-effect-level (NOAEL) is an important part of the non-clinical risk assessment. It is a professional opinion based on the design of the study, indication of the drug, expected pharmacology, and spectrum of off-target effects.
2.5: NOAEL and LOAEL - Chemistry LibreTexts
WEBThese terms refer to the actual doses used in human clinical or experimental animal studies. They are defined as follows: NOAEL — Highest dose at which there was not an observed toxic or adverse effect. LOAEL — Lowest dose at which there was an observed toxic or adverse effect.
No-Observed-Adverse-Effect Level - an overview - ScienceDirect
WEBThe NOAEL is defined as the highest dose (or exposure concentration) at which no statistically significant and/or biologically relevant adverse effects are observed in “any adequate developmental toxicity study.”
NOAEL | SpringerLink
WEBJan 1, 2024 · The term “no-observed-adverse-effect level” (NOAEL) refers to an organism’s level of exposure that, when determined through experiment or observation, results in no physiologically significant rise in the severity of any adverse effects of the tested protocol.
NOAEL - an overview | ScienceDirect Topics
WEBNOAEL. NOAEL, in the context of Chemistry, refers to the highest dose level that does not cause a significant increase in adverse effects compared to the control group. It is different from the no observed effect level and is determined by …

WEBMar 1, 2022 · Adversity determination facilitates the identification of a dose at which there is no adverse effect (NOAEL; no-observed-adverse-effect-level). The NOAEL has been the most common approach used to calculate a maximum recommended starting dose (MRSD) for FIH clinical trials. 1

WEBThe typical way this is done in drug safety investigations is by examining study data, often with focus on clinical signs, clinical pathology and histopathology, to determine a No-Observable-Effect-Level (NOEL) and/or a No-Observable-Adverse-Effect-Level (NOAEL).
No observed adverse effect level (NOAEL) – REVIVE
WEBDefinition: Highest dose of a drug that does not produce a significant increase in adverse effects in comparison to a control group in clinical (human) or preclinical studies (animal). Calculating NOAELs is an important aspect of risk assessment in drug development.
WEBThe NOEL (No Observed Effect Level) or NOAEL (No Observed Adverse Effect Level) is often the single statistic taken from a toxicology study, or series of studies, for use in risk assessment calculations.
