Creating a single pill isn’t as simple as mixing a few chemicals together. The journey of a Essential vs Harmful Drugs begins with science—lots of it.
Phase 1: Research and Discovery of Essential vs Harmful Drugs
Scientists study how fat works, how hormones regulate hunger, and what molecules might influence these systems. A potential compound is created in a lab, and if it shows promise in test tubes, it moves to the next phase.
Phase 2: Testing on Animals
This stage checks safety—does the drug work? Does it cause harm? If the answers are positive, the drug gets a green light for human trials.
Phase 3: Clinical Trials on Humans
These trials happen in stages:
- Phase I: Small group of healthy people
- Phase II: Larger group of people who need the treatment
- Phase III: Thousands of participants to confirm effectiveness and monitor side effects
Phase 4: Mass Manufacturing
Once approved by agencies like the FDA, EMA, or DRAP (Pakistan), the drug goes to mass production—always under strict regulations. It’s produced in sterile, high-tech facilities that follow GMP (Good Manufacturing Practices).
