Psychosis: Goals of Pharmacotherapy01:26

Psychosis: Goals of Pharmacotherapy

476
Antipsychotic drugs are a crucial treatment method for acute and chronic psychoses, bipolar illness, and behavioral disorders. The selection of these drugs depends on several factors, including the state of the disease, clinical judgment, possible drug interactions, and the patient's sensitivity to adverse effects. In immediate scenarios, such as delirium and dementia, short-term treatment with low doses of high-potency typical or atypical agents can effectively manage symptom exacerbation.

Antipsychotic Drugs: Typical and Atypical Agents01:21

Antipsychotic Drugs: Typical and Atypical Agents

768
Antipsychotic drugs are classified into first-generation (typical) drugs including phenothiazines; and second-generation (atypical) drugs. Chlorpromazine hydrochloride (Thorazine), a phenothiazine derivative, broadly impacts the central, autonomic, and endocrine systems. This drug, along with typical agents like haloperidol (Haldol), primarily works by antagonizing D2 receptors, thus reducing dopaminergic neurotransmission. However, typical antipsychotics can cause side effects such as sedation...

Antiepileptic Drugs: Potassium Channel Activators

637
Ezocgabine or retigabine, an antiepileptic drug of remarkable efficacy, has revolutionized the management of seizures. It is a potassium channel activator, explicitly targeting the family of Q subtype potassium channels. It enhances the transmembrane potassium currents, regulating neuronal excitability. This action stabilizes the resting membrane potential, a pivotal factor in mitigating the hyperexcitability that characterizes epilepsy.
Ezogabine has gained approval as an adjunctive treatment...

Antipsychotic Drugs: Therapeutic Uses and Side Effects

761
Antipsychotic drugs primarily block dopamine and serotonin receptors and cholinergic, adrenergic, and histaminergic receptors, thereby reducing hallucinations and delusions in conditions like schizophrenia. However, they can trigger unwanted extrapyramidal effects such as dystonias, Parkinson-like symptoms, and tardive dyskinesia.
Despite these side effects, antipsychotics are used therapeutically for various purposes, including managing schizophrenia, preventing nausea and vomiting, curbing...

Psychosis and Antipsychotic Drugs: Overview

820
The term "psychosis" refers to a spectrum of mental disorders characterized by abnormal thoughts, perceptions, and behaviors. It can manifest as mood disorders, dementia, delirium with psychotic features, substance-induced psychosis with psychotic features, brief psychotic disorder, delusional disorder, schizoaffective disorder, and schizophrenia. Among all these disorders, schizophrenia is the most common psychotic disorder, affecting 1% of the worldwide population. Psychotic...

Mania and Antimanic Drugs: Overview

561
Mania, a psychological condition characterized by elevated mood, increased energy, and reduced sleep need, is part of the bipolar disorder cycle. The exact cause of mania isn't entirely known, but it is thought to be a combination of genetic, environmental, and neurological factors. Bipolar disorder involves alternating manic and depressive episodes. Mood stabilizers like lithium, antipsychotics, and anticonvulsants help manage these episodes. Lithium carbonate is particularly effective as...

Area of Science:

  • Pharmacology
  • Neuroscience

Background:

  • Olanzapine is a second-generation antipsychotic (SGA) used in Japan for schizophrenia and bipolar disorder.
  • It targets multiple receptors, including dopamine, serotonin, adrenaline, histamine, and muscarinic receptors, classifying it as a multi-acting receptor targeted antipsychotic (MARTA).

Observation:

  • Comparative studies, including meta-analyses and large-scale trials (CATIE, EUFEST), have evaluated olanzapine against other antipsychotics.
  • Olanzapine's broad receptor affinity profile is a key characteristic.

Findings:

  • Olanzapine exhibits higher efficacy in treating schizophrenia and bipolar disorder.
  • It also shows a lower discontinuation rate compared to other antipsychotic medications.

Implications:

  • These findings suggest olanzapine may be a preferred treatment option for patients requiring antipsychotic therapy.
  • Further research could explore optimal patient populations and long-term outcomes associated with olanzapine's multi-acting receptor profile.
