Originally synthesized by accident in the 1960s, metoclopramide is a medication with multiple classifications. Answering the question, **what category of drug is metoclopramide?**, reveals its complexity as both a potent antiemetic and a prokinetic agent, primarily working through its effects on dopamine and serotonin receptors.

In 2023, metoclopramide was prescribed over a million times in the United States, making it a widely used drug for gastrointestinal issues [1.7.1]. Despite its common use, a critical question remains for patients and clinicians: **can metoclopramide cause psychosis** and other severe neuropsychiatric effects?

Haldol (haloperidol) is one of the most widely used first-generation antipsychotic drugs in the world, known for its potency and effectiveness in treating severe psychiatric conditions. Understanding exactly what kind of antipsychotic Haldol is involves exploring its classification, mechanism of action, and distinctive side effect profile compared to newer medications.

Available in many countries, domperidone is a medication that primarily acts as a dopamine antagonist to treat symptoms of nausea, vomiting, and certain gastrointestinal motility disorders. Its approved and off-label uses vary widely around the world, leading to differing availability and safety guidelines.

Yes, pimozide is a dopamine blocker, as its mechanism is centered around the blockade of dopaminergic receptors in the central nervous system. The U.S. Food and Drug Administration (FDA) has noted this dopaminergic blocking activity as the likely function for its effectiveness in suppressing tics in Tourette's disorder.

Sulpiride, known by brand names such as Dogmatil, is a medication primarily classified as an atypical antipsychotic, belonging to the benzamide class of drugs. This classification distinguishes it from older typical antipsychotics by its unique and selective pharmacological profile, which influences its therapeutic effects and side-effect tendencies. However, its history and mechanism sometimes lead to confusion regarding its categorization, a nuance worth exploring.

In 2023, generic metoclopramide was widely prescribed for gastrointestinal conditions, making it a familiar name to many. The primary answer to what is another name for Reglan? is its generic equivalent, metoclopramide. However, several other brands also contain this active ingredient, which is used to treat conditions like gastroparesis and severe GERD.

Metoclopramide is a medication commonly prescribed for gastrointestinal issues like gastroparesis and nausea, but it is not an antipsychotic drug. Its mechanism of action, however, involves blocking dopamine receptors, leading to a crucial pharmacological overlap with true antipsychotics and causing similar neurological side effects.

Droperidol, a potent and fast-acting medication, was developed in 1961 and is a member of the butyrophenone class of drugs. For decades, its use has evolved, but the core question of **what classification is droperidol** remains central to understanding its diverse applications and significant safety considerations.

In a 2014 retrospective review of 268 patients treated with the antipsychotic fluphenazine for Tourette's, 80.5% showed moderate tic improvement [1.9.1]. For severe cases unresponsive to standard therapies, the question arises: **what does pimozide do** as an alternative treatment? This antipsychotic works by altering brain chemistry to control symptoms [1.2.1, 1.2.2].
