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.
So, how long does Imodium last in the system of normal people? This compound stays in for a minimum of half a day in normal adults. The effect of Imodium is not equal for all adults of the same age group. Further, the time for wearing off the healing effect induced by its consumption also varies from person to person.
