In forensic toxicology, tests for drugs are specifically defined as either qualitative, confirming the presence or absence of a substance, or quantitative, measuring its precise concentration. The answer to whether drugs are used qualitative or quantitative is not a simple either/or, but rather a sophisticated interplay of both principles throughout a drug's lifecycle, from discovery to clinical application.

In pharmacology, the half-maximal inhibitory concentration (IC50) is a critical measure for assessing a drug's potency, representing the concentration required to inhibit a biological process by 50%. This value is fundamental to drug discovery and understanding inhibitory effectiveness. So, is high or low IC50 better for a medication?

Did you know a drug's ED50 can vary based on a patient's genetics and age, influencing how clinicians determine the right dosage for effective treatment? What is ED 50? It's a fundamental pharmacological concept that helps researchers and clinicians understand a medication's potency and balance its efficacy against potential toxicity.

Adverse drug reactions (ADRs) are a significant public health issue, with some studies indicating they are a leading cause of death. Understanding **what is pharmacodynamics**—the study of a drug's effects on the body—is crucial for maximizing therapeutic benefits and minimizing these risks.
