Success here is not guarantee of human success (the "translational gap"), but failure here is a definitive stop.
The Backbone of Medicine: Why Pharmacology is the Unsung Hero of Drug Discovery and Development
Pharmacology determines how a drug enters the bloodstream. Is it orally bioavailable? Does it survive stomach acid? Do gut transporters like P-glycoprotein pump it back into the lumen? Modern drug discovery uses high-throughput Caco-2 cell assays (mimicking human intestinal epithelium) to predict absorption before animal studies. pharmacology in drug discovery and development
How the drug enters systemic circulation from its site of administration. Bioavailability ( ), peak plasma concentration ( Cmaxcap C sub m a x end-sub ), time to peak ( Tmaxcap T sub m a x end-sub
To understand the role of pharmacology in drug development, one must first understand its two primary branches. These disciplines quantify how a drug interacts with the body and how the body processes the drug. Pharmacodynamics (PD): What the Drug Does to the Body Success here is not guarantee of human success
The journey of a new drug begins long before it is ever tested in humans. In the early stages, pharmacologists work hand-in-hand with medicinal chemists and molecular biologists to pinpoint and validate new treatments. 1. Target Identification and Validation
The Backbone of Medicine: Why Pharmacology is the True Hero of Drug Discovery & Development Does it survive stomach acid
: The ability of the compound to target the designated biomarker without interacting with structurally similar, off-target proteins, which reduces potential side effects.
From measuring the affinity of a lead compound for its receptor using surface plasmon resonance, to interpreting a Phase III PK/PD analysis that saves the label from a “boxed warning,” pharmacology is the thread that weaves chemistry, biology, and clinical medicine into a coherent whole.
