Cabergoline: Description of the Drug and Its Effect on the Body

Cabergoline is a medication primarily used to treat conditions associated with high levels of the hormone prolactin. As a dopamine agonist, it mimics the effects of dopamine in the brain, which plays a crucial role in regulating various bodily functions.

Mechanism of Action

Cabergoline works by stimulating dopamine receptors in the brain, particularly the D2 receptors. This action leads to a decrease in prolactin secretion from the pituitary gland, helping to restore hormonal balance in patients suffering from hyperprolactinemia.

Key Effects on the Body

• Reduction of Prolactin Levels: By inhibiting prolactin secretion, cabergoline helps alleviate symptoms caused by elevated prolactin, such as irregular menstrual cycles and infertility.
• Impact on Dopamine Levels: As a dopamine agonist, cabergoline can enhance mood and overall well-being by increasing dopamine activity in the brain.
• Potential Weight Effects: Some patients may experience weight loss due to its appetite-suppressing effects associated with enhanced dopaminergic activity.
• Impact on Sexual Function: Cabergoline may improve sexual function in individuals whose libido has been affected by high prolactin levels.

Common Uses

Cabergoline is commonly prescribed for several medical conditions, including:

1. Hyperprolactinemia
2. Prolactinomas (noncancerous tumors of the pituitary gland)
3. Acromegaly (excess growth hormone)

Dosage and Administration

The dosage of cabergoline varies based on the specific condition being treated and the patient’s response to the medication. It is typically taken orally, and it’s important to follow a healthcare provider’s instructions closely. Common dosing guidelines include:

• Starting doses usually range from 0.25 mg to 0.5 mg, given twice weekly.
• Doses may be adjusted based on prolactin levels and side effects.

Possible Side Effects
