Felix Hoffmann to investigate the substance's efficacy and tolerability had been completed, it was found to be an analgesic, antipyretic and antiinflammatory substance. The company then worked to develop a cost-effective production process that would facilitate the promising active ingredient to be supplied as a pharmaceutical product. In 1899 it was marketed for the first time under the trade name "Aspirin", initially as a powder supplied in glass bottles. He also synthesized diamorphine (heroin), previously achieved by Charles Romley Alder Wright. Following the synthesis of aspirin, Hoffmann moved to the pharmaceutical marketing department where he stayed until his retirement in 1928. He
Analgesic nephropathy between the 1960s and 1980s. As the use of phenacetin declined, so too did the prevalence of analgesic nephropathy as a cause of end-stage kidney disease. Data from Switzerland, for example, demonstrated a decline in the prevalence of analgesic nephropathy among people with end-stage kidney disease, from 28% in 1981 to 12% in 1990. An autopsy study performed in Switzerland suggested that the prevalence of analgesic nephropathy in the general population has likewise decreased; the prevalence was 3% in 1980 and 0.2% in 2000. While these data demonstrate that analgesic nephropathy has been all but eliminated in some regions, in
