In my latest deep dive, I've traced the history of Loperamide, a common anti-diarrheal medicine. After its discovery in the 1960s, it wasn't until the late 70s that it was approved for medical use. Its initial use was limited due to concerns over potential abuse, but it has since become a household name under the brand Imodium. Nowadays, it's widely recognized and used globally for short-term relief of diarrhea. However, it's not without controversy as misuse can lead to serious heart problems, reminding us that even common medicines need to be used responsibly.
