Development of New Drugs
Creating a new medicine isn't as simple as mixing chemicals in a lab and hoping for the best. Drug development is a lengthy process that can take over a decade and costs millions of pounds.
Most new drugs start their journey in pharmaceutical laboratories where chemists synthesise compounds, though some originate from natural sources like plants. Before any human gets near these potential medicines, scientists must prove three crucial things: efficacy (does it actually work?), toxicity (is it safe?), and dosage (how much should people take?).
Preclinical testing happens first, using cells, tissue samples, and live animals to check basic safety. Only if these tests succeed can the drug move to human trials. Clinical trials follow four stages: healthy volunteers test small doses for safety, a few patients try low doses to see if it works, larger patient groups test different doses to find the optimum amount, and finally a double-blind trial determines true effectiveness.
Quick Tip: Remember the three T's - Testing, Trialling, and Time. Every medicine you've ever taken has gone through this rigorous process to keep you safe.
