Master the science of drug action. From molecular mechanisms to clinical dosing, build a physician-grade understanding of how medicines work.
Absorption, distribution, metabolism, and excretion. How the body processes drugs over time from administration to elimination.
How drugs produce their effects in the body. Receptor binding, agonism, antagonism, and the dose-response relationship.
Molecular targets: agonists activate receptors; antagonists block them. How structural changes at the cellular level create clinical effects.
Time for drug concentration to halve. Determines dosing frequency, accumulation risk, and how quickly steady state is reached.
Hepatic breakdown of oral drugs before systemic circulation. Why some drugs require different routes or higher oral doses.
Side effects are expected and dose-related; adverse reactions are unpredictable. Identifying, managing, and reporting safety signals.
