Felix Hoffmann was born on 21 January 1868 in Ludwigsburg, Germany, the son of an industrialist. In 1889 he started studying chemistry at the Ludwig Maximilian University of Munich to study pharmacy and ended it
Analgesic nephropathy kidney toxicities of NSAIDs and the antipyretics phenacetin and paracetamol may combine to give rise to analgesic nephropathy. A committee of investigators reported in 2000 that there was insufficient evidence to suggest that non-phenacetin analgesics by themselves are associated with analgesic nephropathy. Proper kidney function depends upon adequate blood flow to the kidney. Kidney blood flow is a complex, tightly regulated process that relies on a number of hormones and other small molecules, such as prostaglandins. Under normal circumstances, prostaglandin E2 (PGE) produced by the kidney is necessary to support adequate blood flow to the kidney. Like all prostaglandins, PGE
