Parlodel is a synthetic derivative of ergot alkaloid bromocriptine used as a dopamine agonist. It binds to d2 receptors in the hypothalamus and pituitary. This blockade reduces prolactin secretion from lactotroph cells. Consequently it lowers circulating prolactin levels in the blood. The decreased hormone level leads to resumption of normal menstrual cycles and restoration of fertility in hyperprolactinemic women. In addition to prolactin inhibition it also stimulates dopamine pathways that improve motor control. The cumulative effect provides therapeutic benefit for galactorrhea and infertility related to hyperprolactinemia.

Parlodel is a dopamine agonist that acts primarily on d2 receptors in the brain and pituitary gland. Pharmacodynamically it stimulates prolactin release inhibition and reduces estrogen secretion by suppressing hypothalamic releasing factors. The drug enhances dopaminergic signaling which leads to inhibition of lactotroph cells in the anterior pituitary. Clinically it is used to treat hyperprolactinemia and associated menstrual disturbances. It also decreases breast milk production by lowering prolactin levels. Its ability to modulate dopamine pathways results in direct inhibition of lactation and restoration of normal endocrine balance.

Common reactions Parlodel can cause include nausea and gastrointestinal discomfort. Dizziness and light-headedness are frequently reported during treatment. Headaches may occur as part of the body's adjustment to the medication. Fatigue and a general sense of low energy are typical side effects. Some users experience mild constipation or changes in bowel habits. Skin reactions such as rash or itching can occasionally appear.

Parlodel may cause nausea as a common side effect. It can also lead to dizziness in some users. Headache is frequently reported during treatment. Fatigue often accompanies the medication. Orthostatic low blood pressure is a typical reaction. Some patients experience vomiting after taking the drug. Skin rashes can appear in rare but documented cases. The medication may also cause abdominal cramps.
