Unfortunately, the exact mechanisms of antipsychotic-induced weight gain antipsychotic induced hyperprolactinemia and hypothyroidism unclear. Data suggest that there is an increased prevalence of obesity, diabetes, and dyslipidemia in patients with schizophrenia and bipolar disorder compared with the general population. De Rivera and collaborators found that, in women both young and old, chronic neuroleptic therapy of at least 5 years resulted in significantly lower prolactin levels than the acute administration of neuroleptics in similar doses 2—4 weeks.

Epidemiology, implications and mechanisms underlying drug-induced weight gain in psychiatric patients.

  • Hyperprolactinemia in association with subclinical hypothyroidism. Recently, the focus on the tolerability of antipsychotics has shifted from extrapyramidal syndrome EPS toward adverse effects on body weight and related metabolic consequences that seem to be more common with atypical than with typical antipsychotics.

  • To examine whether serum PRL levels Immune system ibduced associated with the prevalence of thyroid autoantibodies in patients with schizophrenia receiving long-term antipsychotic treatment, we determined serum PRL, thyrotropin, free thyroxine levels, and the presence of antithyroid peroxidase and antithyroglobulin antibodies in 75 consecutive, clinically stable schizophrenic outpatients who had been on stable doses of antipsychotics for at least 3 months, and had no history of overt thyroid disease.

  • For all treatment changes, women must be warned that menses may resume along with fertility. Balancing effectiveness of psychotropic medications with their potential for adverse effects is a crucial component of the successful treatment of mental disorders.

  • Pituitary adenomas are the most common cause of hyperprolactinemia, which results from either direct production by the adenoma prolactinoma or the stalk effect.

Antipsychotic-induced hyperprolactinaemia in women: pathophysiology, severity and consequences: selective literature review. A prolactin-sparing effect is sometimes included in the definition, but risperidone would then be excluded. De Rivera and collaborators incuced that, in women both young and old, chronic neuroleptic therapy of at least 5 years resulted in significantly lower prolactin levels than the acute administration of neuroleptics in similar doses 2—4 weeks. However, prolactin levels were not significantly different between menstruating and post-menopausal women and, although the percentage of post-menopausal women was the greatest in the group with DP over 10 years, the differences between the three DP groups regarding the proportion of menstruating and post-menopausal women were not statistically significant.

Amisulpride increases prolactin levels even in low doses, which means that decreased dose of amisulpride has little result on enhancing hyperprolactinaemia [ 63 ].

Harold E. This results in different effects on the four dopaminergic pathways: in the limbic system, it decreases positive psychotic symptoms; in the tuberoinfundibular system, it causes hyperprolactinaemia; and in the and hypothyroidism system, it can result in extrapyramidal symptoms EPS. Prolactin, hyperprolactinaemia and antipsychotic treatment: a review and lessons for treatment of early psychosis. If this proves difficult, then an endocrinologist should be consulted and the risks and benefits of hormone replacement considered. In patients treated with antipsychotics, hyperprolactinemia is the consequence of dopamine D2 receptors blockade in the pituitary gland, which is positioned outside of the blood-brain barrier. Table 3. Obesity as a risk factor for antipsychotic noncompliance.

Blood pressure and fasting glucose and lipid levels should be checked at 3 months and then annually even though earlier recommendations had proposed antipsychotic induced hyperprolactinemia and hypothyroidism every 5 years if lipid levels were normal at 3 months Typical antipsychotics block dopamine inhibition of the pituitary and cause prolactin rise Atypical antipsychotics act on serotonin receptors and have a lower incidence of EPS and negative symptoms Risperidone can cause sustained hyperprolactinaemia Hyperprolactinaemia results in hypogonadism and may cause osteoporosis Consider hyperprolactinaemia in a woman presenting with amenorrhoea while taking antipsychotics Consider changing the antipsychotic in symptomatic hyperprolactinaemia References. For example, olanzapine exhibits greater occupancy of brain receptors compared to pituitary receptors [ 40 ]. Discussions Conventional or typical antipsychotics are commonly associated with elevated prolactin serum levels, with haloperidol being the most potent drug in terms of its increasing prolactin levels. The significant hyperprolactinemia generated by risperidone compared to other atypical antipsychotics might be explained by its lower capacity of passing through the blood-brain barrier and its high affinity for D2 receptors that are present in the pituitary gland [ 41 ]. Chanson P, Young J.

Prolactin levels were determined by the Timisoara Emergency County Hospital using the activated chemo-luminescence method. Imduced a caus-al relationship cannot be excluded, it seems more likely that symptomatic hyperprolactinemia developed in patients receiving antipsychotics, particularly risperidone, who then underwent MRI scanning of the pituitary as part of a diagnostic evaluation. Prolactin acts on the hypothalamus to suppress the secretion of gonadotropin-releasing hormone, which results in decreased secretion of luteinizing hormone and follicle-stimulating hormone and, ultimately, hypogonadism. Atypical antipsychotics have a higher affinity for 5HT 2A compared to D2 receptors. Antipsychotic-induced hyperprolactinaemia. Why the difference?

Abstract Background Antipsychotic medication, stress, gender, and age are factors that influence prolactin levels in patients with psychosis. Antipsychotics and hyperprolactinemia Hypothyfoidism secretion is primarily regulated through the suppressive action of dopamine, which is secreted from hypothalamic neurons and delivered to the anterior pituitary through the hypothalamic-pituitary portal blood vessels. Lippincott, Williams and Wilkins: Philadelphia. Another issue that must be taken into consideration is the fact that prolactin levels can also be dependent of menstrual cycles in women, our sample containing 75 Antipsychotics were also classified according to potency of inducing hyperprolactinemia in prolactin raising strongly associated with hyperprolactinemia: haloperidol, amisulpride, risperidone and prolactin sparing less associated with hyperprolactinemia: aripiprazole, clozapine, olanzapine, quetiapine, ziprasidone.

However, there is also evidence that the degree of the serum prolactin elevation hyperprolactinemia and hypothyroidism correlate with clinical response [ 17 ]. Remitted patients, who relapse, show lower neuroleptic and prolactin serum levels before the relapse episodes than before the stable periods [ 21 ]. There is evidence that a number of patients on long term neuroleptic treatment show normal prolactin levels [ 30 ]. Lippincott, Williams and Wilkins: Philadelphia.
