Bromocriptine is the active ingredient of Parlodel.
General Information
In South Africa bromocriptine is often prescribed to suppress breast milk production after stillbirth, abortion, or when the mother whish to stop breastfeeding (or if breastfeeding is contraindicated). This medication is also indicated in treating the absence of a menstrual period in women of reproductive age, the over-secretion of breast milk, unassociated with childbirth, some types of female (and occasionally male) infertility and a lack of function of the ovaries or testis.
Bromocriptine is also effective in treating advanced Parkinsonism when other drugs have failed. It should however not be used in Parkinsonism associated with dementia, as mental disturbances may be exacerbated.
This medication has an inhibiting effect on the secretion of growth hormone, and has been successfully used in the treatment of acromegaly - a condition associated with extreme enlargement of the extremities, which can result in severe disfigurement.
How does bromocriptine work?
Bromocriptine prevents the secretion of the hormone prolactin in the brain, making it effective in treating conditions associated with excessive prolactin secretion.
The medication makes dopamine receptors more susceptible to this neurotransmitter, and is therefore effective in treating Parkinson's disease.
