How Has Insulin Therapy Evolved Over Its First Century?
One hundred years of insulin therapy reveals a remarkable paradox: while the medication has evolved from crude pancreatic extracts to sophisticated engineered proteins with improved safety and convenience, it has simultaneously transformed from an affordable necessity accessible to all patients into an expensive commodity that forces many to ration life-saving treatment. This century-long journey encompasses extraordinary scientific achievement alongside troubling healthcare policy failures.
Dr. Kumar’s Take
The centennial of insulin therapy should be a celebration of one of medicine’s greatest triumphs, but instead it highlights our healthcare system’s moral failure. We’ve achieved remarkable scientific progress - from animal insulin to human insulin to precision analogs - yet we’ve simultaneously betrayed Frederick Banting’s vision of insulin as a gift to humanity. The fact that patients today die from rationing insulin while pharmaceutical companies generate billions in profits represents a complete inversion of medical ethics. We’ve perfected the science while corrupting the mission.
Key Findings
The analysis reveals distinct phases in insulin therapy evolution: discovery and early production (1922-1940), purification and standardization (1940-1980), genetic engineering revolution (1980-2000), and analog development with pricing crisis (2000-present). Each phase brought meaningful improvements in insulin purity, predictability, and convenience, but the most recent phase has been marked by exponential price increases that far exceed the value of therapeutic improvements.
Scientific advances include the transition from animal to human insulin, development of rapid-acting and long-acting analogs, and sophisticated delivery systems. However, these improvements have been accompanied by patent manipulation strategies that maintain artificial scarcity and prevent generic competition, transforming insulin from a commodity into a luxury product.
Brief Summary
This comprehensive review examines insulin therapy’s evolution from Leonard Thompson’s first injection in 1922 through modern analog formulations and delivery systems. The analysis covers scientific advances, manufacturing improvements, regulatory developments, and the emergence of access barriers that have created a two-tiered system where insulin availability depends on wealth rather than medical need. The study evaluates both therapeutic progress and policy failures that have shaped insulin’s first century.
Study Design
This historical analysis synthesized clinical literature, patent documents, regulatory filings, pricing data, and patient outcome studies to evaluate insulin therapy’s evolution over 100 years. Researchers examined the relationship between therapeutic improvements and cost increases, analyzed international variations in insulin access, and assessed the impact of policy interventions on patient outcomes. The study compared scientific progress with accessibility trends to understand how insulin therapy has succeeded and failed over its first century.
Results You Can Use
The research demonstrates that insulin therapy has achieved remarkable scientific progress while simultaneously creating artificial access barriers through policy failures. Therapeutic improvements have been genuine but incremental, while price increases have been exponential and unjustified. Countries with effective price regulation have maintained insulin accessibility without compromising innovation, proving that current U.S. pricing reflects policy choices rather than economic necessities.
Why This Matters For Health And Performance
Understanding insulin therapy’s complete history helps patients, providers, and policymakers distinguish between genuine therapeutic advances and artificial market manipulation. This perspective supports informed treatment decisions, policy advocacy, and recognition that current access barriers represent departures from historical norms rather than inevitable consequences of scientific progress. The centennial perspective also highlights the urgency of restoring insulin’s accessibility before more patients die from rationing.
How to Apply These Findings in Daily Life
- Understand that insulin’s scientific progress doesn’t justify current pricing
- Explore older insulin formulations that may be equally effective and more affordable
- Advocate for policies that restore insulin’s accessibility while supporting continued innovation
- Learn about international examples of successful insulin price regulation
- Support organizations working to ensure insulin access for all patients
- Consider the complete history when evaluating healthcare policy proposals
- Recognize that current pricing represents policy failure, not scientific necessity
Limitations To Keep In Mind
This centennial analysis may not fully capture regional variations in insulin development or access patterns outside major markets. The focus on insulin therapy may not address broader diabetes care evolution, including glucose monitoring, dietary management, and other therapeutic advances. Additionally, projecting future trends based on historical patterns requires caution given rapidly changing healthcare policies and technologies.

FAQs
How has insulin improved over 100 years?
Insulin has evolved from crude animal extracts to pure human insulin and precision analogs with predictable action profiles. Modern formulations offer better glucose control, reduced side effects, and more convenient dosing schedules than early preparations.
Why has insulin become so expensive despite being 100 years old?
Pharmaceutical companies use patent manipulation strategies to prevent generic competition, treating insulin as a proprietary product rather than a century-old medication. This artificial scarcity enables price increases that far exceed the value of therapeutic improvements.
What does the future hold for insulin therapy?
Emerging developments include glucose-responsive insulin formulations, ultra-long-acting preparations, and oral insulin delivery systems. However, ensuring these advances remain accessible will require policy reforms to prevent the pricing failures that have marked insulin’s recent history.
Conclusion
One hundred years of insulin therapy demonstrates both the power of scientific innovation and the danger of treating life-saving medications as luxury commodities. As we enter insulin’s second century, we must recommit to Frederick Banting’s vision of insulin as a gift to humanity while continuing to support the research that will bring even better treatments. The greatest tribute to insulin’s first century would be ensuring that its second century serves all patients equally, regardless of their ability to pay.
