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.
Opiates are a group of narcotics that contain opium or a derivative of opium, either natural or synthetic and have a sedative effect. They are also called opioids. Many of the pain killers important to medical practice are this type of medication. They are legally available only by prescription.
