Pharmaceutical testing is a crucial process that ensures new drugs are safe and effective before they reach the market. This testing typically involves several phases, including laboratory research, animal studies, and clinical trials with human participants. Each phase is designed to assess the drug's safety, dosage, and potential side effects. Once a drug passes these tests, it must be reviewed and approved by regulatory agencies, such as the U.S. Food and Drug Administration (FDA). This rigorous evaluation helps protect public health by ensuring that only safe and effective medications are available to patients.
