Description: Penicillin is a type of antibiotic drug that belongs to the class of beta-lactam antibiotics. It is widely used in the treatment of various bacterial infections caused by sensitive organisms. Discovered by Sir Alexander Fleming in 1928, penicillin revolutionized the field of medicine by significantly reducing the mortality rate associated with infections. It inhibits the growth of bacteria by interfering with their ability to build a cell wall, thus weakening and eventually eliminating them.
