Pharmacology In Drug Discovery And Development

Once a target is validated, high-throughput screening (HTS) begins. Pharmacologists test libraries of millions of compounds to find a "hit." But finding a molecule that binds isn't enough. Three quantitative parameters determine a molecule’s PD profile:

[Target Identification] ➔ [Target Validation] ➔ [Hit-to-Lead Screening] ➔ [Lead Optimization] ➔ [Candidate Selection] 1. Target Identification and Validation pharmacology in drug discovery and development

The integration of computational modeling, particularly , has revolutionized the drug development process [5.1]. Once a target is validated, high-throughput screening (HTS)

Once in humans, the role of pharmacology evolves from predictive to confirmatory and exploratory. This is often called . Once a target is validated

Efficacy alone is insufficient. A drug must be safe, and pharmacology defines safety.

Balancing high efficacy with minimal toxicity remains a major focus of toxicological pharmacology [5.3].
