An explanation of why pharmaceutical firms avoid developing new antibiotics.

Compounding the problem is a severe drought in the pharmaceutical pipeline. For major drug corporations, developing a new antibiotic is a financially unappealing venture. The research and development process takes over a decade and costs billions of dollars, yet the financial return is minimal. Because new antibiotics must be used sparingly as a last resort to prevent further resistance, sales volumes remain low. Pharmaceutical companies prefer to invest their capital in lucrative drugs for chronic conditions, such as diabetes or heart disease, which patients must take daily for the rest of their lives.

When exposed to antimicrobial drugs, the weakest bacteria die, but those possessing mutant genes survive. These resilient strains reproduce rapidly, passing on their resistant traits. The passage emphasizes that bacteria become resistant to the drugs, not the human body itself. 3. Human Catalysts: Overuse and Misuse
