The objective of a study classified under Human Pharmacology primarily focuses on assessing tolerance and defining drug metabolism. This phase is crucial as it provides critical insights into how a drug behaves in the human body, including its pharmacodynamics (what the drug does to the body) and pharmacokinetics (how the body affects the drug). Understanding these aspects is vital for determining the appropriate dosage and frequency of drug administration, as well as identifying any immediate side effects or adverse reactions.

In addition to this, Human Pharmacology studies play an essential role in laying the groundwork for further clinical trials by establishing a well-defined safety profile and understanding how the drug is metabolized in the human system, which informs subsequent studies on efficacy and long-term effects. This understanding is necessary before progressing to later phases of trials, which often evaluate the drug's effectiveness and safety over a more extended period and in larger populations.
