Brand vs Generic Drug Prices — Compare & Save

Q: Why are brand name drugs so much more expensive?

Brand name drug prices include the cost of research, development, and clinical trials (often $1-2 billion per drug), plus marketing costs. Patent protection gives manufacturers exclusive rights for ~20 years. After patents expire, generic manufacturers can produce the same drug at a fraction of the cost because they don't bear the original R&D expenses.
