It decreases prolactin synthesis, DNA synthesis, cell multiplication, and overall size of prolactinoma. This is probably due to either decreased clearance or increased production of prolactin as a result of disordered hypothalamic regulation of prolactin secretion.

Initially it was thought that patients would require lifelong dopamine agonist therapy but the current use has evolved into a dynamic process depending on the patient’s requirement. A new complication of the ergot derivative dopamine agonists. Hiprrprolactinemia resistant to standard doses of cabergoline: However, hormone replacement therapy HRT to replenish estrogen deficit should be given to all patients with amenorrhea. Histamine has a predominantly stimulatory effect due to the inhibition of the dopaminergic system.


It is worth noting that many premenopausal women with hyperprolactinemia do not have galactorrhea, and many with galactorrhea do not have hyperprolactinemia.


Unfortunately, excision is often incomplete and therefore relapse occurs hiperprolactinmeia though prolactin levels are lower than before. Kisspeptin, when administered exogenously, has the ability to reverse the hypogonadotropic effects of hyperprolactinemia and can also restore pulsatile LH secretion.

The main biological action of prolactin is inducing and maintaining lactation. Prolactin PRL plays a central role in a variety of reproductive functions.

Nil Conflict of Interest: There may be continuing abnormality of the hypothalamus giving rise to chronic stimulation of the lactotrophs. Bromocriptine is a lysergic acid derivative ajenorrea a bromine substitute at position 2. Galactorrhea, a typical symptom of hyperprolactinemia, occurs in less than half the cases.

Sign in via Shibboleth. Progressive trabecular osteopenia in women with hyperprolactinemic amenorrhea. Others are lisuride, pergolide, quinagolide, terguride, and metergoline. Eur J Clin Invest. Such forms are rarely physiologically active hipsrprolactinemia may register in most prolactin assays.

You can also find results for a single author or contributor. GnRH pulses–the regulators of human reproduction. Nos macroprolactinomas, o manejo deve ser individualizado. Long-term follow-up of prolactinomas: However, lactation is inhibited by the high levels of estrogen and progesterone during pregnancy.



Unlike other tropic hormones secreted by the anterior pituitary gland, prolactin secretion is controlled primarily by inhibition from the hypothalamus and it is not subject to negative feedback directly or indirectly by peripheral hormones. In these patients, treatment with a dopamine agonist should be avoided since it might compromise the effectiveness of the psychotropic drug and the patient should simply be treated with replacement of sex steroids. Further evaluation is done with 6 monthly prolactin levels.

Anovulation, galactorrhea, hyperprolactinemia, prolactin, prolactinomas. It has a short half-life and so it requires twice daily administration to maintain optimal suppression of prolactin levels. Bromocriptine is the first option for this condition and has now been used for the longest period of time. This may explain many cases of very high prolactin levels sometimes found in normally ovulating women and do not require any treatment.

Radiotherapy for prolactin-secreting pituitary tumors. Clinical presentation in women is more obvious and occurs earlier than in men. Blood coagulation, fibrinolysis and lipid profile in patients with prolactinoma. Diagnosis and treatment of hyperprolactinemia: Increased circulating levels of bromocriptine after vaginal compared with oral administration.
