Contents 1 Indications 1.1 Side effects 2 Chemistry 3 See also 4 External links 5 References

Indications

Amenorrhea, female infertility, galactorrhea, hypogonadism, and acromegaly may all be caused by pituitary problems, such as hyperprolactinaemia, and therefore, these problems may be treated by this drug.

Side effects

Bromocriptine use has been associated with causing or worsening psychotic symptoms (its mechanism is in opposition of most antipsychotics, whose mechanisms generally block dopamine).^[1]

Chemistry

Like all ergopeptides, bromocriptine is a cyclol; two peptide groups of its tripeptide moiety (shown in black at the upper left of the Figure) are crosslinked, forming the >N-C(OH)< juncture between the two rings with the amide functionality.
