Morphine's isolation established the field of alkaloid chemistry and proved that pure chemical compounds underlie the activity of crude plant drugs. This principle—that pharmacologically active …
Aspirin exemplifies the pharmaceutical optimisation of a natural product: chemical modification converted an effective but irritating compound into a tolerated drug. It also illustrates how …
Receptor theory transformed pharmacology from a descriptive to a mechanistic science. The concept that drugs act by binding to specific molecular targets—and that [[term:selectivity|selectivity]] for …

Chlorpromazine founded biological psychiatry and created the field of psychopharmacology. It demonstrated that severe psychiatric illness had a biological substrate amenable to pharmacological intervention, shifted …
Imipramine established depression as a biologically treatable illness and founded the tricyclic antidepressant class. Its mechanism underpinned the monoamine hypothesis of depression, which— despite its …
Thalidomide's teratogenic catastrophe revealed that drugs can have completely different toxicological profiles across species and developmental stages, revolutionised preclinical reproductive toxicology requirements, and established that …
The Kefauver-Harris Amendment established [[term:efficacy|efficacy]] as a regulatory requirement alongside safety, making the randomised controlled trial central to drug approval globally. Its framework—pre-clinical testing, IND …
Propranolol validated receptor-targeted drug design as a strategy—demonstrating that systematic application of receptor pharmacology to a defined clinical need could produce a world-changing drug. The …
Vane's discovery of aspirin's mechanism founded modern eicosanoid pharmacology and established prostaglandins as key mediators of inflammation, pain, and fever. It led directly to the …
Hybridoma technology made it possible to produce unlimited quantities of a precisely defined antibody, transforming diagnostics and creating the largest and fastest-growing class of biopharmaceuticals. …
Cimetidine was the first drug deliberately designed by rational receptor-pharmacology methodology to achieve commercial and clinical success, validating Black's approach and demonstrating that rational drug …
Captopril was the first drug designed using the structure of a target enzyme's active site— inaugurating structure-based drug design as a practical drug discovery strategy. …
Recombinant insulin proved that genetic engineering could produce therapeutic human proteins at commercial scale with acceptable safety—founding the biotechnology pharmaceutical industry. Its approval established the …
Muromonab-CD3's approval opened the regulatory pathway and established clinical proof-of-concept for all subsequent therapeutic monoclonal antibodies. Its limitations—murine immunogenicity and cytokine release syndrome—directly drove the …
AZT demonstrated that HIV replication could be pharmacologically inhibited, transforming AIDS from a uniformly fatal illness into a treatable condition—though full therapeutic transformation awaited combination …
Lovastatin inaugurated the statin era, which produced the most robust cardiovascular mortality reduction data of any drug class. Statins demonstrated that sustained LDL lowering translates …
Fluoxetine demonstrated that SERT [[term:selectivity|selectivity]] could produce antidepressant [[term:efficacy|efficacy]] with a safety and tolerability profile that made treatment of depression practical for primary care physicians. …
Omeprazole established proton pump inhibition as the dominant strategy for acid suppression, achieving more profound and sustained gastric acid reduction than H2 antagonists and enabling …
Saquinavir validated structure-based drug design against a viral enzyme and provided the first [[term:protease-inhibitor|protease inhibitor]] building block for HAART, which transformed HIV/AIDS from a death …
Rituximab was the first approved anti-cancer [[term:monoclonal-antibody|monoclonal antibody]], proving that Ehrlich's magic bullet concept was clinically achievable. It established CD20 as a validated oncology target, …
Sildenafil illustrated that rigorous attention to unexpected clinical signals during trials can salvage—and dramatically redirect—a failing programme. It created the PDE5 inhibitor drug class, established …
Trastuzumab demonstrated that an oncogenic driver gene—present in a defined patient subset— could be pharmacologically silenced with a [[term:monoclonal-antibody|monoclonal antibody]], dramatically improving outcomes in a …
Imatinib proved the concept that a single oncogenic kinase can be pharmacologically silenced by a small molecule, converting a lethal leukaemia into a manageable chronic …
Completing the human genome reference sequence provided the foundational resource for all subsequent genomic medicine: GWAS, [[term:pharmacogenomics|pharmacogenomics]], rare-disease gene discovery, and cancer genomics. It catalysed …
The rofecoxib withdrawal reshaped [[term:pharmacovigilance|pharmacovigilance]] globally, prompting mandatory post-marketing commitments, expanded use of FDA's Sentinel System for real-world safety monitoring, and more stringent cardiovascular risk …
Bevacizumab validated Judah Folkman's angiogenesis hypothesis after three decades of controversy and launched the anti-VEGF drug class. It established tumour vasculature as a legitimate therapeutic …
Gardasil established that a vaccine could prevent a human malignancy by eliminating the causative infectious agent. It validated the VLP platform as safe and highly …
Ipilimumab proved that releasing immunological brakes could produce durable tumour regression and long-term survival in a cancer previously resistant to all systemic therapy. It established …
Sofosbuvir made chronic hepatitis C—a major global cause of cirrhosis and hepatocellular carcinoma affecting 70 million people—curable with a short oral course in virtually all …
The 2013 CAR-T results demonstrated that genetically engineered autologous immune cells could achieve deep and durable complete remissions in patients with haematological malignancies refractory to …
