Comments2 Share. This is a list of characters from the Nickelodeon animated comedy series SpongeBob SquarePants. The main characters in the show are SpongeBob SquarePants and his pet snail Gary, SpongeBob's friends Patrick, Squidward and Sandy, and two restaurateur rivals; Mr. Krabs and Plankton.
Technically, Imodium (Loperamide) is an opiate, but it only binds to the mu receptors in the GI tract; and doesn't cross the BBB (Blood Brain Barrier) into the CNS (Central Nervous System) like other opiates do.
Imodium is like a light sedative for your digestive muscles. Instead of treating what's inside the gut (like Pepto Bismol and others), it slows down the muscles of your digestive tract so they move much more slowly and (in my case) stop spasming.
