The Vital Role of Pharmacology in Drug Discovery and Development

• Toxicology Studies: Pharmacologists administer the drug to animals to determine the maximum tolerated dose. They look for "off-target" effects—where a drug meant for the heart, for example, accidentally disrupts the kidneys.
• Dose Prediction: Using PK/PD modeling, pharmacologists predict how the drug will behave in humans. They mathematically extrapolate animal data to determine the starting dose for human trials—a calculation that balances the need for therapeutic effect with the paramount importance of safety.

Screening: Testing thousands of compounds against the target. pharmacology in drug discovery and development

Today, we use systems pharmacology—using computer models to predict how a drug will affect an entire human network of proteins, not just one receptor. We also use reverse pharmacology, where we start with a traditional herbal remedy and work backward to find the active molecule and its target. The Vital Role of Pharmacology in Drug Discovery
