Chemotherapy-Induced Nausea and Vomiting: Dopamine Receptor Antagonists01:29

Chemotherapy-Induced Nausea and Vomiting: Dopamine Receptor Antagonists

Dopamine receptor antagonists, also known as antipsychotic agents, are critical in managing chemotherapy-induced vomiting. These antiemetic agents block dopamine receptors in the chemoreceptor trigger zone (CTZ), inhibiting signal transmission to the vomiting center. Antipsychotic agents encompass phenothiazines (PTZ), butyrophenones, benzamides, and thienobenzodiazepines (Zyprexa), which are utilized for their antiemetic and sedative properties.
Phenothiazines, such as prochlorperazine...

Psychosis and Antipsychotic Drugs: Overview

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 symptoms in all...

Antipsychotic Drugs: Therapeutic Uses and Side Effects

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: Goals of Pharmacotherapy

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. For...

Antidepressant Drugs: MAOIs and Other Agents

Atypical antidepressants, including bupropion (Wellbutrin), mirtazapine (Remeron), nefazodone (Serzone), trazodone (Desyrel), and vilazodone (Viibryd), offer unique mechanisms of action. Bupropion weakly inhibits dopamine and norepinephrine reuptake, aiding depression treatment and smoking cessation, with a low risk of sexual dysfunction. Mirtazapine enhances serotonin and norepinephrine neurotransmission, leading to sedation, increased appetite, and weight gain. As a result, it helps treat...
Mania and Antimanic Drugs: Overview01:24

Mania and Antimanic Drugs: Overview

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 a...

Summary

Antipsychotic drug-induced amenorrhea can negatively impact women with schizophrenia, affecting contraception use and sense of femininity. Efforts should focus on preventing this significant side effect.

Area of Science:

  • Psychiatry
  • Women's Health
  • Reproductive Health

Background:

  • Antipsychotic medications for schizophrenia frequently cause amenorrhea.
  • The broader impact of this side effect remains under-researched.

Purpose of the Study:

  • To review the literature concerning the significance of menstruation for women.
  • To explore the meaning of menstruation across diverse cultures and for women with schizophrenia.

Main Methods:

  • A comprehensive literature review was conducted.
  • The review synthesized findings on the meanings of menstruation in general, cross-culturally, and specifically for women diagnosed with schizophrenia.

Main Results:

  • Menstruation holds ambivalent meanings for many women.

  • Menstrual loss in women with schizophrenia can lead to issues like contraceptive failure, pseudocyesis, pregnancy denial, perceived early menopause, and diminished femininity.
  • Conclusions:

    • Preventing antipsychotic-induced amenorrhea is crucial.
    • Clinical strategies should aim to mitigate this adverse effect in women with schizophrenia.
