Refining chemical structures to improve efficacy and reduce toxicity [5.2]. 2. Pharmacology in Drug Development: PK/PD Profiling
The Strategic Importance of Pharmacology in Early Drug Discovery pharmacology in drug discovery and development
These parameters are not academic abstractions. A safe drug might require a high affinity for the target but low affinity for off-target sites (selectivity). A partial agonist (low efficacy) might be ideal for a system where full activation would be toxic—such as in opioid receptors for pain management. Refining chemical structures to improve efficacy and reduce
Pharmacology evaluates drug candidates using two main metrics: A safe drug might require a high affinity
: Researchers pinpoint specific biological molecules, like receptors or enzymes, linked to a disease.
This article provides a deep dive into the pivotal role of pharmacology in the drug discovery and development process. We will explore its core components—pharmacokinetics (PK) and pharmacodynamics (PD)—as well as its critical functions in safety assessment, regulatory science, and how it is being transformed by cutting-edge technologies like artificial intelligence (AI) and precision medicine.
