What are clinical trials?
research studies designed to evaluate the effects, safety, and efficacy of drugs that act on the brain and behaviors
Drugs tested in these trials typically target:
• Depression
• Anxiety
• Schizophrenia
• Bipolar disorder
• ADHD
• Substance use disorders
• Sleep disorders
These are carefully regulated experiments on humans, often broken into phases:
• Phase I: Safety and dosage (small number of healthy volunteers or patients)
• Phase II: Efficacy and side effects (larger patient group)
• Phase III: Comparison with standard treatments, large-scale (hundreds or thousands)
• Phase IV: Post-marketing surveillance (after approval)
📋 Key Points:
• Participants are typically patients with mental health conditions.
• Trials must follow Good Clinical Practice (GCP) and ethical regulations.
• Informed consent is mandatory for all participants.
• Results influence drug approval and labeling.
