What is the most prescribed drug of all time?

Could you please elaborate on what the most prescribed drug of all time is? I'm curious to understand what specific medication holds this title and why it has become so widely used. Perhaps it's a drug that has been around for decades, addressing a common health concern or ailment. Alternatively, it could be a more recent discovery that has revolutionized treatment for a particular condition. I'm eager to learn more about its history, purpose, and potential impact on public health.
