Pharmacometrics

Pharmacometrics is a scientific field that uses mathematical and statistical models to measure and predict how drugs, diseases, and patients interact. It helps scientists understand drug safety, design better clinical trials, and find the right dose for patients. 

Key Areas of Focus

Pharmacokinetics (PK): What the body does to a drug (absorption, distribution, breakdown, and removal).
Pharmacodynamics (PD): What the drug does to the body (beneficial effects and side effects).
Disease Progression: How a medical condition changes over time with or without treatment.

Main Uses

Dose Optimization: Figuring out the safest and most effective dose for different groups, like children or the elderly.
Drug Development: Making clinical trials faster and cheaper by using computer simulations instead of human tests.
Regulatory Decisions: Helping government groups, such as the FDA Division of Pharmacometrics, decide if a new medicine is safe to approve.
