Drug trials, also known as clinical trials, are research studies that test the safety and effectiveness of new medications or treatments on human subjects. These trials help researchers and healthcare providers determine the potential benefits and risks of a new drug before it is approved for public use. Drug trials typically follow a rigorous protocol that outlines the study objectives, eligibility criteria for participants, dosages and administration of the drug, and monitoring procedures. Participants in drug trials are closely monitored throughout the study to track their response to the treatment and any potential side effects. The results of drug trials help inform medical decision-making and drug approval processes.
