Summary
Antipsychotics can cause high prolactin levels (hyperprolactinaemia), leading to sexual dysfunction and osteoporosis. Monitoring and adjusting medication or using hormone replacement can manage these side effects.
Area of Science:
- Endocrinology
- Psychiatry
- Pharmacology
Background:
- Hyperprolactinaemia is a frequent side effect of antipsychotic medications.
- Antipsychotic-induced hyperprolactinaemia is linked to dopamine D(2) receptor interactions and blood-brain barrier penetration.
- This condition contributes to sexual dysfunction and long-term risks like osteoporosis in patients with severe mental illness.
Purpose of the Study:
- To review the causes and consequences of antipsychotic-induced hyperprolactinaemia.
- To discuss monitoring strategies and management options for this condition.
- To highlight the importance of addressing hyperprolactinaemia to prevent complications.
Main Methods:
- Literature review on antipsychotic-induced hyperprolactinaemia.
- Analysis of the relationship between antipsychotic properties and prolactin elevation.
- Discussion of clinical implications and treatment strategies.
Main Results:
- Different antipsychotics vary significantly in their potential to cause hyperprolactinaemia.
- Hyperprolactinaemia can lead to sexual dysfunction and bone density loss (osteoporosis).
- Early detection through regular monitoring is crucial.
Conclusions:
- Antipsychotic-induced hyperprolactinaemia is a common and significant issue requiring clinical attention.
- Management strategies include dose adjustment, switching antipsychotics, or sex steroid replacement.
- Preventing long-term complications like osteoporosis is a key aspect of patient care.

01:24Mania 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...
01:28Psychosis 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...
01:21Antipsychotic 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...

01:28Drug Therapy
The advent of drug therapy has profoundly shaped modern mental health care, providing targeted treatments for a range of psychological disorders. Psychotherapeutic drugs, classified into antianxiety, antidepressant, and antipsychotic medications, address symptoms across anxiety disorders, mood disorders, and schizophrenia. While these medications have transformed patient outcomes, they require careful management due to their potential side effects and limitations.

01:26Psychosis: 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...
01:24Parkinson's Disease: Treatment
Neurodegenerative disorders, such as Parkinson's Disease (PD), involve the gradual and irreversible destruction of neurons in particular brain areas. These disorders exhibit standard features like proteinopathies, selective vulnerability of some neurons, and an interaction of intrinsic properties, genetics, and environmental influences in neural injury.
Parkinson's Disease is primarily a result of the loss of dopaminergic neurons in the substantia nigra pars compacta. The cornerstone of its...
