The ADME toxicology testing market plays a fundamental role in modern drug development by ensuring that candidate drugs are safe, effective and biocompatible. In short, \"ADME\" stands for absorption, distribution, metabolism, and excretion, the biochemical processes that determine that a drug is absorbed into the body, distributed into tissues, metabolized, and ultimately eliminated. When \"toxicology testing\" is added, the scope increases; it includes not only a drug moves through the body (ADME), but also harmful effects it causes.
