Loperamide is an anti-diarrheal agent that is available as various over-the-counter products for treating diarrhea.[L42785] The drug was first synthesized in 1969 and used medically in 1976.[A251610] It is a highly lipophilic synthetic phenylpiperidine opioid [A251610] that is structurally similar to opiate receptor agonists such as [diphenoxylate] and [haloperidol].[A6249] Due to pharmacological properties, loperamide has been misused and abused to self-manage opioid withdrawal symptoms and to induce euphoria.[A251610, A251625] However, loperamide is associated with a risk for experiencing a range of adverse effects, often life-threatening, if taking for non-therapeutic reasons or at doses higher than the recommended dose.[L42790]
