Summary
Drug-induced hyperprolactinemia is common, with antipsychotics like risperidone being frequent culprits. Reversing this condition may involve switching to olanzapine or clozapine.
Area of Science:
- Endocrinology
- Pharmacology
Background:
- Hyperprolactinemia is a prevalent endocrine disorder with diverse causes.
- Elevated prolactin levels can stem from physiological, pathological, and iatrogenic factors.
- Drug-induced hyperprolactinemia is a significant clinical concern, often linked to specific medications.
Purpose of the Study:
- To review the causes and management of drug-induced hyperprolactinemia.
- To highlight the role of antipsychotic medications in causing hyperprolactinemia.
- To discuss other drug classes associated with elevated prolactin levels.
Main Methods:
- Literature review of studies on hyperprolactinemia and drug-induced effects.
- Analysis of the mechanisms by which various drugs elevate prolactin.
- Synthesis of information on clinical presentation and management strategies.
Main Results:
- Typical antipsychotics, particularly risperidone, are common causes of drug-induced hyperprolactinemia.
- Women exhibit greater sensitivity to the hyperprolactinemic effects of antipsychotics.
- Antidepressants (SSRIs, MAO-I), prokinetics, opiates, and other agents can also elevate prolactin.
- Management may involve antipsychotic discontinuation and switching to agents like olanzapine or clozapine.
Conclusions:
- Drug-induced hyperprolactinemia is a manageable condition with appropriate therapeutic adjustments.
- Understanding the iatrogenic causes of hyperprolactinemia is crucial for effective patient care.
- Further research into the long-term effects and management of drug-induced hyperprolactinemia is warranted.

01:28Drugs Affecting GI Tract Motility: Dopamine Receptor Antagonists
Prokinetic agents are specialized medications that stimulate gastrointestinal (GI) motility, promoting food movement through the GI tract. Dopamine, an inhibitory neurotransmitter, plays a significant role in this process, reducing GI motility and indirectly controlling the speed of digestion. Dopamine receptor antagonists, such as metoclopramide and domperidone, offer a unique advantage as prokinetic agents. By blocking the dopamine receptors, these drugs increase GI motility, improving food...
01:27Major Hormones and Their Functions
Hormones, the biochemical messengers produced by endocrine glands, are pivotal in regulating bodily functions and maintaining homeostasis. Each hormone's balance is crucial; imbalances can lead to significant physiological disruptions. Major hormones include oxytocin, cortisol, epinephrine, estrogen, testosterone, thyroxine, growth hormone, insulin, and glucagon.
Oxytocin, produced in the hypothalamus and released by the pituitary gland, plays a role in social bonding, childbirth, and lactation.

01:27Hyperthyroidism II: Pathophysiology
Hyperthyroidism is a hypermetabolic state caused by elevated levels of thyroid hormones, triiodothyronine (T3) and thyroxine (T4). It results from dysregulation at the thyroid, pituitary, or immune system level and affects multiple organ systems.PathophysiologyThe most common cause of hyperthyroidism is Graves’ disease, an autoimmune disorder in which antibodies, specifically thyroid-stimulating antibodies (TSAb), a subtype of TSH receptor antibodies (TRAb), bind to and activate TSH receptors...
01:27Hormones of the Pituitary Gland
The small, pea-sized pituitary gland is located at the base of the brain. It is crucial in regulating various bodily functions, from growth to reproduction. The gland is divided into the anterior lobe and the posterior lobe. The secretory cell clusters in the pars distalis of the anterior pituitary lobe are controlled by hypothalamic regulators and synthesize six primary hormones.
The most abundantly secreted hormone from the anterior lobe is the growth hormone, which controls overall growth by...

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...
01:23Treatment for Pulmonary Arterial Hypertension: Prostacyclin Receptor Agonists
Prostacyclin receptor agonists are a class of therapeutic agents integral to managing pulmonary arterial hypertension (PAH). These drugs operate by mimicking the action of prostaglandin I2, or PGI2, a naturally occurring compound in the body.
These agonists bind to the IPR receptor situated on the plasma membrane of the pulmonary artery smooth muscle cells. This binding triggers a cascade of reactions known as the GS-AC-cAMP-PKA pathway. This pathway results in the relaxation of smooth muscle...
