penicillin

Penicillin is an antibiotic medication that combats bacterial infections. It works by disrupting the cell wall formation of bacteria, causing them to weaken and eventually die, while leaving human cells unaffected. Discovered in 1928 by Alexander Fleming, penicillin was the first antibiotic widely used to treat various infections such as pneumonia, strep throat, and syphilis. It revolutionized medicine by providing an effective way to fight bacterial diseases. While highly effective, some bacteria have developed resistance, so it's important to use penicillin responsibly under medical guidance.
