Penicillin has not changed over the years from it's invention in 1928. You have developed some derivatives of penicillin, discovered for more than half century ago. You have penicillin V, injection procaine penicillin, injection benzathine penicillin. Then you have semisynthetic penicillins like ampicillin and amoxicillin. Then you have carboxypenicillins like carbenicillin and ureidipenicillins like piperacillin.
