Cabgolin (Cabergoline 0.25mg) Tablets

Cabgolin general information

What is Cabgolin used for?

Cabgolin tablets 0.25mg are used to treat disorders due to high levels of the hormone prolactin (hyperprolactinaemia) that can cause hormonal and menstrual disturbances in women during reproductive years including amenorrhoea (absence of periods), oligomenorrhoea (irregular periods), anovulation (when the ovaries do not release an egg during the menstrual cycle) and galactorrhoea (spontaneous release of breast milk unrelated to childbirth and breastfeeding).  Hyperprolactinaemia can also cause impotence in men and changes in breast tissue in both men and women.  Prolactin is a peptide hormone produced by the anterior pituitary gland, the lower end of the hypothalamus at the base of the brain, that plays an important role in various reproductive functions.  Abnormally high levels of prolactin can be due to a pathology like empty sella syndrome (a deformity of the pituitary gland), a prolactin secreting pituitary adenoma (tumour) or there may be no known reason (idiopathic).  The major physiological role of prolactin is to stimulate milk producing breast cells to proliferate and to induce and maintain milk production by the breast.  Cabgolin tablets 0.25mg are also used to prevent the onset of lactation following childbirth when the mother has elected not to breast feed or when breast feeding is contraindicated for the mother and the baby for medical reasons; or after a stillbirth or abortion to suppress lactation and dry up the milk supply.  

How does Cabgolin work?

Cabgolin tablets 0.25mg contain cabergoline, a dopaminergic drug belonging to the group of ergoline derivatives (structural skeleton is the alkaloid ergoline).  Prolactin secretion is under tonic inhibitory control by dopamine, a brain hormone produced by the hypothalamus.  When dopamine is released, prolactin release is inhibited, therefore, prolactin is released only when dopamine production by the hypothalamus is inhibited.  Cabergoline in Cabgolin tablets 0.25mg acts a dopamine agonist that directly stimulates dopamine receptors on the anterior pituitary cells that produce prolactin, to increase levels of dopamine and decrease prolactin levels.  This action of cabergoline in Cabgolin tablets 0.25mg provides potent, rapid and long-lasting inhibition of prolactin secretion, acting within three hours and maintaining its prolactin lowering effect for between one and four weeks.  Cabgolin tablets 0.25mg are effective in inhibiting milk secretion, as well as breast engorgement and pain after childbirth; also returning high prolactin to normal levels and relieving symptoms of hyperprolactinaemia by restoring normal menstrual cycle. 

What does Cabgolin contain?

Cabgolin tablets 0.25mg contain the active ingredient cabergoline, a dopamine agonist used to treat conditions due to high prolactin levels (hyperprolactinaemia) and to prevent milk production following childbirth. 

Treating hyperprolactinaemia with Cabgolin

Cabgolin tablets 0.25mg contain cabergoline, a dopamine agonist that is used to treat conditions due to high prolactin levels (hyperprolactinaemia).  Prolactin is a hormone produced by the anterior pituitary gland in brain that plays an important role in various reproductive functions.  Abnormally high levels of prolactin can be due to a pathology like empty sella syndrome (a deformity of the pituitary gland), a prolactin secreting pituitary adenoma (tumour) or there may be no known reason (idiopathic).  Hyperprolactinaemia can cause hormonal and menstrual disturbances in women during reproductive years including amenorrhoea (absence of periods), oligomenorrhoea (irregular periods), anovulation (when the ovaries do not release an egg during the menstrual cycle) and galactorrhoea (spontaneous release of breast milk unrelated to childbirth and breastfeeding).  Prolactin secretion is regulated by the brain hormone dopamine, produced by the hypothalamus that inhibits prolactin release.  Cabergoline in Cabgolin tablets 0.25mg acts a dopamine agonist by directly stimulating dopamine receptors on the anterior pituitary cells that produce prolactin, to increase levels of dopamine and decrease prolactin levels.  Cabgolin tablets 0.25mg are effective in returning high prolactin to normal levels and relieving symptoms of hyperprolactinaemia by restoring normal menstrual cycle. 

Cabgolin for preventing lactation

Cabgolin tablets 0.25mg contain cabergoline, a dopamine agonist that is used to either prevent lactation or dry up milk production after childbirth, still birth or an abortion.  Prolactin is a hormone produced by the anterior pituitary gland in brain and its major physiological role is to stimulate milk producing breast cells to proliferate and to induce and maintain milk production by the breast.  Prolactin secretion is regulated by the brain hormone dopamine, produced by the hypothalamus that inhibits prolactin release.  Cabergoline in Cabgolin tablets 0.25mg acts as a dopamine agonist by directly stimulating dopamine receptors on the anterior pituitary cells that produce prolactin, to increase levels of dopamine and decrease prolactin levels.  This action of Cabergoline in Cabgolin tablets 0.25mg suppresses lactation and helps dry up the milk supply, being effective rapidly and lasting for several weeks.
