Charles Romley Alder Wright several hours and produced a more potent, acetylated form of morphine, now called "diamorphine (or diacetylmorphine)", also known as heroin. After Wright's death, Heinrich Dreser, a chemist at Bayer Laboratories, continued to test heroin. Bayer marketed it as an analgesic and 'sedative for coughs' in 1898. When its addictive potential was recognized, Bayer ceased its production in 1913. In 1892, Wright was the first to report the existence of the stoichiometric intermetallic compound AlSb (aluminium antimonide), which is now recognized as a compound semiconductor with potential use in high-frequency, low-power consumption microelectronics applications, as well as gamma radiation detection. In
Analgesic nephropathy abnormal urinalysis results, high blood pressure, and anemia. A small proportion of individuals with analgesic nephropathy may develop end-stage kidney disease. Analgesic nephropathy was once a common cause of kidney injury and end-stage kidney disease in parts of Europe, Australia, and the United States. In most areas, its incidence has declined sharply since the use of phenacetin fell in the 1970s and 1980s. Common findings in people with analgesic nephropathy include headache, anemia, high blood pressure (hypertension), and white blood cells in the urine (pyuria). Some individuals with analgesic nephropathy may also have protein in their urine (proteinuria). Complications of
