bromocriptine and its Impurities
Bromocriptine is used to treat acromegaly and conditions associated with hyperprolactinemia like amenorrhea, infertility, and hypogonadism, prolactin-secreting adenomas; it is also used to prevent ovarian hyperstimulation syndrome. It was patented in 1968 and approved for medical use in 1975.. Reference standards of Bromocriptine API, and its pharmacopeial, non pharmacopeial impurities, and stable isotopes are listed below
