Prækliniske

Prækliniske refers to studies conducted before human clinical trials. These investigations aim to establish the safety and efficacy of a new treatment, drug, or medical device in laboratory settings or animal models. The primary goal of prækliniske research is to gather sufficient data to justify proceeding with human testing. This phase is crucial for understanding a potential therapy's mechanism of action, determining appropriate dosage ranges, identifying potential toxicities, and assessing its overall therapeutic potential.

These studies typically involve a combination of in vitro experiments, which are performed in test tubes or cell cultures, and in vivo experiments, which are conducted in living organisms, most commonly animals like mice, rats, or non-human primates. In vitro studies help researchers understand how a substance interacts with biological systems at a cellular or molecular level. In vivo studies provide a more comprehensive picture of how the substance is absorbed, distributed, metabolized, and excreted by the body, as well as its effects on physiological systems and potential side effects.

The data generated from prækliniske studies are meticulously analyzed and compiled into regulatory submissions that are reviewed by health authorities, such as the Food and Drug Administration (FDA) in the United States or the European Medicines Agency (EMA) in Europe. If the prækliniske data are deemed promising and demonstrate an acceptable safety profile, the regulatory agency may grant approval to initiate clinical trials in human subjects. This transition from prækliniske to clinical research marks a significant milestone in the development of new medical interventions.
