INVESTIGATIONAL DRUGS Meaning and
Definition
-
Investigational drugs are pharmaceutical substances that are currently undergoing research and analysis for their potential use as medicinal treatments. These drugs are being studied in clinical trials, which are carefully designed experiments conducted on human participants to determine their safety and effectiveness.
Investigational drugs typically emerge in the early stages of drug development, after initial laboratory testing and animal studies have shown promising results. It is important to note that investigational drugs are not approved by regulatory authorities, such as the Food and Drug Administration (FDA) in the United States, for commercial use or distribution. They are not yet available to the general public, except in rare cases when they are part of an expanded access program or compassionate use program for patients with life-threatening conditions.
Clinical trials involving investigational drugs consist of multiple phases, each aimed at different objectives. Phase 1 trials assess the drug's safety and tolerability in a small group of healthy volunteers. Phase 2 trials evaluate the drug's effectiveness and potential side effects in a larger group of patients with the target condition. Phase 3 trials further verify the drug's safety and efficacy in a larger population, comparing it to existing treatments or a placebo. Finally, if the investigational drug successfully completes these phases, it may be eligible for regulatory approval and subsequent commercialization.
Investigational drugs play a crucial role in advancing medical science and expanding treatment options for various diseases and conditions. They represent a bridge between preliminary laboratory research and the availability of new therapies to patients in need.

Etymology of INVESTIGATIONAL DRUGS

1. Investigational: The word "investigational" is derived from the verb "investigate", which dates back to the late 16th century. It comes from the Latin word "investigare", meaning "to trace out", "search", or "track". The term "investigational" is an adjective form of "investigate" and is used to describe anything involved in an investigation or in the process of being investigated.
2. Drugs: The term "drugs" originates from Middle English and is traced back to the late 14th century. It comes from the Old French word "drogue", meaning "medicine", which came from the late Latin word "droga" or "droghe".
