CAS#: 94424-50-7 (HCl)

Description: Quinagolide is a selective, D2 receptor agonist (or prolactin-release inhibitor) that is used for the treatment of elevated levels of prolactin. Quinagolide (Norprolac) was approved in European Community, but not in USA as of December, 2011. Quinagolide prevents the production of a chemical called prolactin. Prolactin is involved in many processes within the body, such as milk production after childbirth and altering levels of hormones involved with controlling the menstrual cycle and fertility. Quinagolide is therefore helpful in reducing prolactin levels to reduce milk production for certain medical reasons and to treat some types of infertility, breast problems and menstrual disorders.
