Once in humans, pharmacology runs the show.
Pharmacology has its roots in ancient civilizations, where people first began to experiment with plant-based remedies to treat various ailments. The Greek physician Hippocrates (460-370 BCE) is often credited with being one of the earliest pharmacologists, as he extensively studied the medicinal properties of plants and their effects on the human body. However, it wasn't until the late 19th century that pharmacology emerged as a distinct scientific discipline. pharmacology in drug discovery and development
When a drug candidate clears preclinical testing, it enters the clinic. Clinical pharmacology is the application of pharmacological principles in human subjects. It represents the ultimate test of the translational science done in the lab. Once in humans, pharmacology runs the show
AI is revolutionizing early-stage drug discovery. Machine learning algorithms can now rapidly screen millions of compounds against biological targets, predict the toxicity of new molecules, and optimize lead compounds much faster than traditional human-led screening methods. Precision Medicine and Pharmacogenomics However, it wasn't until the late 19th century
In the real world, PK and PD are not independent; they are two halves of the same story. The goal of rational drug design is to develop a molecule with favorable PK properties that ensure it reaches its target at a concentration sufficient to engage the desired PD effect. This relationship, often called the , is the basis of modern drug development.
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.
The integration of computational modeling, particularly , has revolutionized the drug development process [5.1].
