A Systematic Review on the Efficacy of Herbal Medicines in the Management of Human Drug-induced Hyperprolactinemia; Potential Sources for the Development of Novel Drugs
S. Hasani- Ranjbar,
Several drugs may increase blood prolactin concentration. Dopamine receptor antagonists are one of the most common causes of hyperprolactinemia. To reduce happening of hyperprolactinemia, some medicinal plants have been traditionally used. This review focuses on the efficacy of effective herbal medicines in the management of human drug-induced hyperprolactinemia. PubMed, Scopus, Web of science, Cochrane library database were searched for any relevant studies that investigated the effect of herbal medicines on drug induced hyperprolactinemia up to May 2010. The inclusion criteria were clinical trials studied efficacy of herbal medicines in drug-induced hyperprolactinemia. Among different compounds, four herbal supplements including Shakuyaku-kanzo-to (TJ-68), Peony-Glycyrrhiza Decoction (PGD), Zhuangyang capsule, Tongdatang serial recipe (TDT) were found clinically effective and safe in management of drug-induced hyperprolactinemia. Although, the quality of included clinical trials was low not allowing us to conduct a meta-analysis but positive results on efficacy (TJ-68), (PGD), Zhuangyang capsule and (TDT) cannot be ignored. Interestingly compounds with prolactin-suppressive effects have a number of diterpenes mainly clerodadienols that seem almost identical for their efficacy. Further studies to isolate and characterize constituents of the effective herbs are needed to reach novel therapeutic and more effective agents.

Any process interfering with dopamine synthesis, its transport to the pituitary
gland, or its action at the level of lactotroph dopamine receptors can cause
hyperprolactinemia (Mancini et al., 2008). Hyperprolactinemia
is mostly seen in women, but also observed in men and even in adolescence and
childhood (Patel and Bamigboye, 2007). Hyperprolactinemia
is a common endocrinological disorder that is caused by many physiological or
pathological conditions (Torre and Falorni, 2007). Women
with oligomenorrhea, amenorrhea, or galactorrhea and men with symptoms of hypogonadism
or impotence or infertility should be checked for blood prolactin to determine
pharmacologic or extrapituitary causes of hyperprolactinemia and neuroradiologic
evaluation of the hypothalamic-pituitary region (Casanueva
et al., 2006).
Several drugs may cause a significant increase in blood prolactin concentration
(Torre and Falorni, 2007) which dopamine D2 receptor
antagonists are the main. These include antipsychotic drugs such as risperidone,
phenothiazines, haloperidol (David et al., 2000),
butyrophenones (Rivera et al., 1976), metoclopramide
(McCallum et al., 1976) and domperidone (Sowers
et al., 1982). These drugs can be categorized for their potency to
the pituitary dopamine receptors that is in correlation with their prolactin
release, as follows: sulpiride>risperidone>haloperidol> olanzapine>clozapine
(David et al., 2000; Markianos
et al., 2001). The high prevalence of psychotic disorders (Perala
et al., 2007) and the need for long-term therapy makes antipsychotic
adverse effects, such as hyperprolactinemia, a major problem. In patients taking
neuroleptic medications, drug-induced hyperprolactinemia should be confirmed
with temporary drug withdrawal or pituitary Magnetic Resonance Imaging (MRI).
Dopamine agonist drugs like bromocriptine, cabergoline, pergolide and quinagolide
are usually the first choice for controlling of hyperprolactinemia but they
have gastrointestinal, cardiovascular and neurological adverse effects (Vance
et al., 1984; Gillam et al., 2006).
Of course, for treatment of drug-induced hyperprolactinemia, combined use of
dopamine antagonists and dopamine agonists is not advised because of increased
risk of side effects (Perovich et al., 1989;
To best of present knowledge, there is no review on the use of herbal medicines in the management of drug-induced hyperprolactinemia. Thus, in the present study, we systematically reviewed all existing data on the efficacy of herbal medicines in the management of drug-induced hyperprolactinemia in human.
MATERIALS AND METHODS
PubMed, Scopus, Web of science, Cochrane library database were searched for any relevant studies that investigated the effect of herbal medicines on hyperprolactinemia up to May 2010. The search terms were: prolactin, hyperprolactinemia, prolactinoma, galactorrhea and herb, herbal medicine, plant, traditional medicine and antipsychotics, neuroleptic, schizophrenia and human.
The quality of trials was assessed by Jadad score for characterizing studies
according to appropriate randomization, blinding and description of study withdrawals
or dropouts (Moher et al., 1995). The description
of this score is as follows:
||Whether randomized (Yes = 1 point, No = 0)
||Whether randomization was described appropriately (Yes = 1 point, No =
||Double-blind (Yes = 1 point, No = 0)
||Was the double-blinding described appropriately (Yes = 1 point, No = 0)
||Whether withdrawals and dropouts were described (Yes = 1 point, No = 0).
The quality score ranges from 0 to 5 points; a low-quality report score is = 2 and a high-quality report score is at least 3.
Three reviewers evaluated studies by reading the title and abstract of the search results to eliminate duplicates, reviews, case studies and letters. The inclusion criteria were clinical trials studied efficacy of herbal medicines in drug-induced hyperprolactinemia.
RESULTS AND DISCUSSION
After searching databases, 48 results were found which only 6 of them were appropriate for inclusion. Four were written in English and 2 in Chinese languages. Full text of 3 English articles and abstract of the 2 Chinese articles were studied. Data were extracted and shown in the Table 1. Four herbal supplements including Shakuyaku-kanzo-to (TJ-68), Peony-Glycyrrhiza Decoction (PGD), Zhuangyang capsule, Tongdatang serial recipe (TDT) were found clinically effective and safe in management of drug-induced hyperprolactinemia.
All of the studies showed a significant decrease in blood prolactin level.
In the first trial, the prolactin levels decreased by more than 50% with Shakuyaku-kanzo-to
(TJ-68) treatment among 5 patients. Plasma prolactin level at 8 weeks was not
significantly different with the baseline. Three of 10 patients, who had complained
of reduced sexual desire, experienced subjective improvement (Yamada
et al., 1997). In the second trial, decreased plasma prolactin level
was observed in nine patients treated with TJ-68 and in four, the plasma prolactin
decreased more than 50%. Subjective improvement of reduced sexual desire was
observed in three patients at 4 weeks (Yamada et al.,
1996).Yamada has reported a case with risperidone-induced amenorrhea
and demonstrated TJ-68 to be effective in correcting neuroleptic-induced amenorrhea
and hyperprolactinemia (Yamada et al., 1999).
The exact mechanism of TJ-68 is unknown although it may have a direct inhibitory
effect on prolactin release from pituitary (Yamada et
al., 1996, 1997). It also decreased estradiol
in rats and this reduction might decrease prolactin levels.In the third trial,
both Peony-Glycyrrhiza Decoction (PGD) and bromocriptine treatment had a similar
percentage of amplitude of the decrease in blood prolactin. Nevertheless, unlike
bromocriptine therapy, the herbal remedy did not cause worsening of psychotic
symptoms, either transiently or individually. Conversely, a significant greater
proportion of patients (nearly 56%) showed improvements on adverse effects related
to hyperprolactinemia during PGD treatment (Yuan et al.,
2008). The PGD with multiple contents including albifloran, paenoiflorin,
benzoylpaeoiflorin, liquiritin and glycyrrhetinic acid had putative mechanisms
and multiple actions deserves needed to be further investigated.
In the fourth trial, after 8 weeks of treatment with either Zhuangyang capsule
(n = 39) or placebo capsule (n = 37) supplemented to risperidone, the serum
level of prolactin decreased significantly, while in the control group, the
prolactin markedly increased.

|BMT: Bromocriptine; PRL: Prolactin; RCT: Randomized control
trial; GAS: Galactorrhea-amenorrhea syndrome
There was a significant difference (decreased 26.51 ng mL-1 vs increased
15.56 ng mL-1) in improvement of serum prolactin in trial group compared
with that of control group. This effect of Zhuangyang capsule was not different
between male and female groups (Chen et al., 2008).
In the fifth trial, serum prolactin reduced in the group treated with Tongdatang
serial recipe (TDT) significantly more than that of control group (Ding
et al., 2008). From 49 patients of the treatment group, 31 patients
got cure (63.3%).
The first two studies did not have control group and were done only in men.
Instead, the third and the fifth ones were done in women, based on the fact
that the incidence of events associated with hyperprolactinemia is much higher
and more severe in women (Yuan et al., 2008).
There are some other herbal medicines which are useful in treatment of hyperprolactinemia,
such as Vitexagnus castus (Wuttke et al.,
2003) but they are not studied on antipsychotic-induced hyperprolactinemia.
The search for chemical identity of the dopaminergic compounds resulted in isolation
of a number of diterpenes of which some clerodadienols were most important for
the prolactin-suppressive effects. They were almost identical in their prolactin-suppressive
properties than dopamine itself.
Although, the quality of included clinical trials was low that is a limitation
of this review not allowing us to conduct a meta-analysis but positive results
on efficacy and safety of Shakuyaku-kanzo-to (TJ-68), Peony-Glycyrrhiza Decoction
(PGD), Zhuangyang capsule and Tongdatang serial recipe (TDT) cannot be ignored.
As herbal medicines produce definite therapeutic effects with few side effects,
in the recent years, many traditionally-used remedies have found evidenced-based
places in novel medicine in various diseases like diabetes (Rahimi
et al., 2010, 2005; Hasani-Ranjbar
et al., 2008, 2010), obesity (Hasani-Ranjbar
et al., 2009a), oxidant- and age-related diseases (Hasani-Ranjbar
et al., 2009b), colitis (Rahimi et al.,
2009), pancreatitis (Mohseni-Salehi-Monfared et
al., 2009a), islet transplantation (Mohseni-Salehi-Monfared
et al., 2009b), bone health and osteoporosis (Salari
et al., 2008) and multi-organ benefits (Momtaz
and Abdollahi, 2010) making the present report worthy. Further studies on
isolation and characterization of their constituents would open a new approach
for novel therapeutic and more effective agents.
This study is the outcome of an in-house study and has not been supported financially.
