Penicillin research. Graph showing the rate of excretion of the antibiotic drug penicillin following intravenous administration. The horizontal axis shows time in hours. The vertical axis shows the amount in the blood (top) together with the percentage in the urine (bottom). Excretion is most rapid in the first two hours. Urine was at times collected to recycle the excreted penicillin. This research dates from around the time of World War II (1939-1945). Penicillin had been discovered in 1928,but was not widely used as an antibiotic until its mass production for the US Army in World War II. Pioneering clinical trials took place in 1939 and in the early 1940s | |
