The Effects of Antipsychotics on Prolactin Levels and Women’s Menstruation

Introduction. Typical and atypical antipsychotic agent is currently used for treatment in the majority of patients with psychotic disorders. The aim of this review is to assess antipsychotic induced hyperprolactinaemia and the following menstrual dysfunction that affects fertility, quality of life, and therapeutic compliance of women. Method. For this purpose, Medline, PsychInfo, Cochrane library, and Scopus databases were accessed, with a focus on the publication dates between 1954 and 2012. Research of references was also performed and 78 studies were retrieved and used for the needs of this review. Results. A summary of several antipsychotics as well as frequency rates and data on hyperprolactinaemia and menstrual disorders for different agent is presented. Conclusion. Diverse prevalence rates of hyperprolactinaemia and menstrual abnormalities have been found about each medication among different studies. Menstruation plays an important role for women, thus, understanding, careful assessment, and management of hyperprolactinaemia could enhance their lives, especially when dealing with women that suffer from a psychotic disorder.

Hyperprolactinemia associated with psychotropics—a review

Different classes of psychotropics can cause hyperprolactinemia to varying degrees. Among antipsychotics, typical agents and risperidone are the most frequent and significant offenders. In this review we discuss the pathophysiology, offending medications, assessment and management of hyperprolactinemia. We did a literature review between 1976 and 2008 using PubMed, MEDLINE, PsychINFO and Cochrane database. Search terms used were prolactin, hyperprolactinemia, psychotropics, antipsychotics, typical antipsychotics, atypical antipsychotics, antidepressants and SSRIs. Prolactin elevation is more common with antipsychotics than with other classes of drugs. Typical antipsychotics are more prone to cause hyperprolactinemia than atypical agents. Management options include discontinuation of offending medication, switching to another psychotropic, supplementing concurrent hormonal deficiencies and adding a dopamine agonist or aripiprazole. Clinicians need to be alert about the potential for hyperprolactinemia and its manifestations with these medications. Prolactin levels need to be monitored and other causes of hyperprolactinemia ruled out in suspected cases.

Hyperprolactinemia Due to Macroprolactin

Abstract: Macroprolactin is a frequently unrecognized phenomenon giving rise to inaccurate diagnosis in an estimated 10% of cases of hyperprolactinemia in the United States. This has been associated with unnecessary investigation and inappropriate treatment including pituitary exploration. Simple laboratory procedures can be adapted to routinely screen hyperprolactinemic sera for macroprolactin. Therefore, it is timely to alert endocrinologists, gynecologists, and all those involved in the management of hyperprolactinemia to macroprolactin, its frequent occurrence and its ready recognition. Demand by clinicians to establish routine screening of hyperprolactinemic sera for the presence of macroprolactin will be useful in leading to adoption of routine screening procedures necessary for the appropriate recognition of the phenomenon.

Diagnosis and management of hyperprolactinemia: Results of a Brazilian multicenter study with 1234 patients

The aim of the study was to evaluate clinical and laboratorial features of 1234 patients with different etiologies of hyperprolactinemia, as well as the response of 388 patients with prolactinomas to dopamine agonists. A total of 1234 hyperprolactinemic patients from 10 Brazilian endocrine centers were enrolled in this retrospective study. PRL measurement, thyroid function tests, and screening for macroprolactin were conducted. Patients were subdivided as follows: 56.2% had prolactinomas, 14.5% drug-induced hyperprolactinemia, 9.3% macroprolactinemia, 6.6% non-functioning pituitary adenomas, 6.3% primary hypothyroidism, 3.6% idiopathic hyperprolactinemia, and 3.2% acromegaly. Clinical manifestations were similar irrespective of the etiology of the hyperprolactinemia. The highest PRL levels were observed in patients with prolactinomas but there was a great overlap in PRL values between all groups. However, PRL>500 ng/ml allowed a clear distinction between prolactinomas and the other etiologies. Cabergoline (CAB) was more effective than bromocriptine (BCR) in normalizing PRL levels (81.9% vs 67.1%, p<0.0001) and in inducing significant tumor shrinkage and complete disappearance of tumor mass. Drug resistance was observed in 10% of patients treated with CAB and in 18.4% of those that used BCR (p=0.0006). Side-effects and intolerance were also more common in BCR treated patients. Prolactinomas, drug induced hyperprolactinemia, and macroprolactinemia were the 3 most common causes of hyperprolactinemia. Although PRL levels could not reliably define the etiology of hyperprolactinemia, PRL values >500 ng/ml were exclusively seen in patients with prolactinomas. CAB was significantly more effective than BCR in terms of prolactin normalization, tumor shrinkage, and tolerability.

Medical causes and consequences of hyperprolactinaemia. A context for psychiatrists

Hyperprolactinaemia is the commonest endocrine disorder of the hypothalamic-pituitary axis and can lead to both short-term sexual dysfunction and galactorrhoea, and long-term loss of bone mineral density. Prolactin is secreted from the anterior pituitary gland under the influence of dopamine, which exerts a tonic inhibitory effect on prolactin secretion. Physiological regulators of prolactin secretion include many different types of 'stress' and sleep. Disruption of the normal control of prolactin secretion results in hyperprolactinaemia from pathological and pharmacological causes. The administration of antipsychotic medication is responsible for the high prevalence of hyperprolactinaemia in people with severe mental illness. Physiological hyperprolactinaemia, such as pregnancy and lactation, should be distinguished from pathological causes to prevent unnecessary investigation and treatment. The causes, consequences and management of hyperprolactinaemia are discussed in this article.

Diagnosis, misdiagnosis and management of hyperprolactinemia

Hyperprolactinemia is a commonly encountered disorder that suppresses both male and female gonadal function. The etiology includes pituitary tumors, hypothalamic or pituitary stalk lesions, drugs and hypothyroidism. In women, the hyperprolactinemic syndrome is characterized by menstrual disorders with or without galactorrhea, while men present with hypogonadism and related symptoms. Occasionally, a pituitary macroadenoma may be associated with pressure symptoms and/or hypopituitarism. Clinically, the most important cause of hyperprolactinemia is a prolactin-secreting pituitary adenoma. The majority of patients with prolactinomas are successfully managed medically with dopamine agonists such as cabergoline or bromocriptine. Misdiagnosis of hyperprolactinemia owing to immunoassay interference by a biologically minimally active form of prolactin termed macroprolactin is common in laboratory medicine. Alhough the etiology of macroprolactinemia is unclear, the condition is commonly associated with the presence of circulating antiprolactin antibodies. In the absence of specific testing, macroprolactin represents a diagnostic pitfall resulting in misdiagnosis and mismanagement of patients. This review examines the investigation and treatment of hyperprolactinemia in the broadened context of screening for macroprolactin and the consequences of failure to identify its presence.

Management of hyperprolactinemia in patients receiving antipsychotics.

Hyperprolactinemia is increasingly prevalent in patients with common psychiatric disorders due to increasing prescriptions of antipsychotics, particularly newer atypical neuroleptics, in these patients. However, measurement of prolactin levels is indicated only in symptomatic patients. When hyper-prolactinemia is diagnosed, work-up should include exclusion of other causes of hyperprolactinemia, particularly those that might require treatment. Once such causes have been ruled out, a minority of patients with antipsychotic medication-induced hyperprolactinemia, including those with clinically significant signs and symptoms, will require treatment. When treatment is indicated, specifically when hyperprolactinemia results in amenorrhea in women or testosterone deficiency in men, dopamine agonist therapy is generally not advisable. Hormone-replacement therapy, which involves estrogen/progestogen in women and testosterone in men, can often prevent modification and interruption of successful psychiatric medication regimens.

Novel approaches to the management of hyperprolactinemia

With improved radiologic detection and monitoring of prolactinomas, the management has shifted away from surgery toward a more conservative approach and medical management. The natural course of a microadenoma appears to be that of a non-progression, and for asymptomatic patients serial radiologic monitoring for growth may be a safe form of management. For symptomatic women, medical management remains the primary mode of therapy. Although bromocriptine remains the most widely used dopamine agonist, its side effects and short half-life have led to the development of newer agonists with better tolerance and similar or superior efficacy. Patients who tolerate oral bromocriptine poorly may find the medication more acceptable when administered either parenterally as with Parlodel LA (Sandoz, Basel, Switzerland), or vaginally. Different medications that have similar efficacy and tolerance to bromocriptine such as pergolide or cabergoline [corrected] may also represent alternatives, as intolerance to one ergot agonist does not necessarily imply intolerance to another. CV-205-502 (Sandoz), a promising and new long-acting nonergot derivative, appears to be safe, effective, and very well tolerated.

Comparison between a Slow-Release Oral Preparation of Bromocriptine and Regular Bromocriptine in Patients with Hyperprolactinemia: A Double Blind, Double Dummy Study

The efficacy and tolerability of a slow-release preparation of bromocriptine (Parlodel SRO) were compared to those of conventional bromocriptine (Parlodel R) in a double blind, double dummy study of 12 hyperprolactinemic women (plasma PRL 81.3 +/- 4.73, ng/ml mean +/- SEM). For 2 weeks, the patients received 2.5 mg b.i.d. Parlodel R or 5 mg once daily Parlodel SRO; for the following 2 weeks, the dose of the drugs was doubled. The patients were then treated, in an open study, with 2.5-10 mg daily Parlodel SRO for 6 months. Both preparations caused a prompt and sharp PRL fall. Hormone levels remained inhibited over the whole month of observation with both preparations. Daily PRL profiles were very close with either drug although morning PRl levels were slightly higher during Parlodel SRO than during Parlodel R administration. Doubling the doses of the two drugs did not result in further significant lowering of PRL values. During the 6-month study with Parlodel SRO, plasma PRL further decreased and normalized in 11 of 12 patients. Clinical improvement occurred in the majority of cases. Tolerability of Parlodel SRO appeared to be better, though without statistically significant differences, than that of Parlodel R. Side effects were less important with the former compound in their number, severity and duration. In conclusion, thanks to its favourable pharmacological profile, Parlodel SRO appears to be a valuable alternative to regular bromocriptine in the management of hyperprolactinemia.

Effectiveness of pergolide mesylate in long term treatment of hyperprolactinaemia.

Twenty five patients with hyperprolactinaemia were treated with pergolide mesylate, a new dopamine receptor agonist. Twenty three received treatment for six to 20 months, and in all serum prolactin concentrations were considerably reduced. In most patients prolactin concentrations were maintained in the normal range by a low, once daily dose of pergolide and reversal of associated reproductive disorders was observed. Tumour volume as assessed by computed tomography decreased considerably during treatment in three out of four patients with a pituitary tumour. The drug was well tolerated. Side effects were similar to those of bromocriptine, but four out of eight patients who had been forced to stop taking bromocriptine because of untoward effects were subsequently able to tolerate treatment with pergolide. Pergolide mesylate promises to be a useful addition to the currently available long acting dopamine agonists in the management of hyperprolactinaemia.
