fyrirklínískar

Fyrirklínískar is an Icelandic term that translates to "pre-clinical" in English. It refers to the stage of research and development that occurs before human testing, particularly in the context of new drugs, medical devices, or treatments. This phase is crucial for evaluating the safety and potential efficacy of an intervention in laboratory settings and animal models.

The primary goals of preclinical studies are to gather essential data on how a substance or device behaves, its biological activity, and its potential toxicity. This typically involves a series of in vitro experiments (conducted in test tubes or cell cultures) and in vivo studies (conducted in living organisms, most commonly laboratory animals). Researchers aim to determine appropriate dosages, identify potential side effects, and establish a scientific rationale for proceeding to human trials.

Key aspects investigated during the preclinical phase include pharmacokinetics (what the body does to the drug), pharmacodynamics (what the drug does to the body), and toxicology. Data generated from these studies are vital for informing regulatory bodies, such as the Food and Drug Administration (FDA) in the United States, about the safety profile of the proposed medical advancement before it can be tested in humans. Successful completion of the fyrirklínískar stage is a prerequisite for obtaining approval to initiate clinical trials.
