Loxapine Succinate is an antipsychotic blocking dopamine and serotonin receptors in the CNS. It treats schizophrenia by reducing hallucinations, delusions, and agitation. Chemical Formula: C₁₈H₁₈ClN₃O·C₄H₆O₄ Mechanism of Loxapine Succinate: Antagonist at D2 and 5-HT2A Intermediate between typical and atypical antipsychotics Uses of Loxapine Succinate: Schizophrenia Agitation in bipolar or psychosis (inhalation form) Side Effects: Sedation … Read more
Thiothixene blocks dopamine receptors, reducing psychotic symptoms with tranquilizing effect. It is an antipsychotic used to manage schizophrenia and related psychiatric disorders. Chemical Formula: C₂₃H₂₉N₃OS₂ Mechanism of Thiothixene: Potent D2 antagonist Low activity at M1/H1 → less sedation, more EPS Uses of Thiothixene: Schizophrenia Side Effects: High EPS risk Akathisia Dystonia Less anticholinergic activity SAR … Read more
Chlorprothixene is a typical antipsychotic blocking dopamine receptor to reduce psychotic symptoms. Its schizophrenia, anxiety, and agitation with calming effects. Chemical Formula: C₁₈H₁₈ClNS Mechanism of Chlorprothixene: D2 receptor antagonist (typical antipsychotic) Also blocks H1, M1, α1 receptors Uses of Chlorprothixene: Schizophrenia Severe agitation Mania (adjunct) Side Effects: Sedation Anticholinergic effects Moderate EPS Notes: Similar to … Read more
Trifluoperazine Hydrochloride is a typical antipsychotic, reducing psychotic symptoms through dopamine antagonism. It treats schizophrenia, anxiety, and severe nausea by blocking dopamine receptors. Chemical Formula: C₂₁H₂₄F₃N₃S·HCl Mechanism of Action: Potent D2 antagonist, especially in mesolimbic tract Minimal effect on muscarinic/H1 receptors Therapeutic Uses of Trifluoperazine Hydrochloride: Schizophrenia Acute anxiety (short-term use) Side Effects of Trifluoperazine … Read more
Prochlorperazine Maleate is a dopamine antagonist, blocking D2 receptors in the brain to control symptoms. Prochlorperazine Maleate treats nausea, vomiting, and psychotic disorders like schizophrenia. Chemical Formula: C₂₀H₂₄ClN₃S·C₄H₄O₄ Mechanism of Action: Strong D2 receptor blockade Acts on chemoreceptor trigger (CTZ) Therapeutic Uses of Prochlorperazine Maleate: Nausea and vomiting Vertigo Schizophrenia Migraine-associated nausea Side Effects of … Read more
Piperacetazine Hydrochloride is a typical antipsychotic that blocks dopamine receptors, reducing symptoms. Piperacetazine Hydrochloride is used to treat anxiety, agitation, and psychotic disorders. Chemical Formula: C₂₁H₂₄ClN₃OS·HCl Mechanism of Piperacetazine Hydrochloride: Strong D2 antagonist Uses of Piperacetazine Hydrochloride: Psychosis Schizophrenia Side Effects: High EPS risk Moderate sedation Anticholinergic effects (less than others)
Triflupromazine is an antipsychotic used to treat schizophrenia and other psychotic disorders. Triflupromazine blocks dopamine receptors, helping to manage symptoms of psychosis. Chemical Formula: C₁₈H₁₉F₃N₂S Mechanism of Action: D2 antagonist, more potent than promazine Uses of Triflupromazine: Severe anxiety and psychosis Nausea/vomiting Side Effects of Triflupromazine: High sedation Orthostatic hypotension Moderate EPS risk
Chlorpromazine Hydrochloride blocks dopamine receptors, offering sedative and antipsychotic properties. Chlorpromazine Hydrochloride treats schizophrenia, nausea, and anxiety through its antipsychotic effects. Chemical Formula: C₁₇H₁₉ClN₂S·HCl Mechanism of Action: Strong D2 receptor blocker (limbic system, basal ganglia) Also blocks α1-adrenergic, muscarinic, and histamine H1 receptors Therapeutic Uses: Schizophrenia Acute psychosis Severe agitation Intractable hiccups Nausea and vomiting … Read more
