APO-Bromocriptine 2.5mg

Apo-Bromocriptine general information

What is Apo-Bromocriptine used for?

Apo-Bromocriptine is a medication that has several uses due to a common mechanism of action that produces different responses in a variety of body systems. These responses can be categorised as endocrinological (hormone function) and neurological (nerve function). Apo-Bromocriptine tablets 2.5mg are primarily used to treat conditions resulting from high levels of prolactin (hyperprolactinaemia), which is a hormone produced by the pituitary gland (a small gland in the base of the brain). Hyperprolactinaemia suppresses normal functioning of the female and male reproductive process and can cause menstrual disorders and infertility; it can also cause over-production of breast milk in men and women (galactorrhoea). Apo-Bromocriptine is used treat menstrual disorders, infertility, galactorrhoea and to suppress milk production for medical conditions such as after a still birth; also to treat prolactinoma, a benign tumour of the pituitary gland that over-produces prolactin. Apo-Bromocriptine tablets 2.5mg have other actions that are used to treat a condition called acromegaly, caused by over-production of growth hormone by the pituitary gland; also to treat Parkinsons Disease either alone as monotherapy or in combination with other anti-parkinsonion drugs.

How does Apo-Bromocriptine work?

Apo-Bromocriptine tablets 2.5mg contain bromocriptine, a dopamine agonist that binds to dopamine receptors in various parts of the brain. Dopamine is a neurotransmitter (chemical that allows communication between nerve cells) produced by certain nerve cells (neurons) in the brain and it plays an important role in controlling hormone secretion; also muscle function and movement. The dopaminergic (stimulates dopamine receptors) action of bromocriptine in Apo-Bromocriptine tablets 2.5mg activates dopamine-stimulated pathways in the brain, and one result of this is the inhibition of prolaction synthesis and secretion from the anterior pituitary gland. Inhibition of prolactin secretion by bromocriptine releases the suppression caused by high prolactin levels on normal functioning of the reproductive glands, which is a cause of infertility and menstrual problems and is thereby effective in treating these conditions. This action also reduces breast milk production, which is dependent on prolactin to stimulate lactation. There are 2 tumours of the pituitary gland that contain dopamine receptors and over produce a pituitary hormone; Prolactinoma that over-produces prolactin, and pituitary adenoma that over-produces growth hormone. Bromocriptine in Apo-Bromocriptine tablets 2.5mg binds to dopamine receptors in the tumour cells, which causes the tumour to shrink and returns the levels of prolactin and growth hormone (respectively) to normal. The abnormal movements associated with Parkinson's disease are caused by low levels of dopamine due to slow and progressive destruction of the neurons that produce dopamine in a certain area of the brain called the substantia nigra. Stimulation of the dopamine receptors in the brain mimics the effect of dopamine and this is thought to be the process by which Apo-Bromocriptine tablets 2.5mg act to improve symptoms associated with Parkinsonism, including tremor, bradykinesia (slowness of movement) and loss of balance.

What does Apo-Bromocriptine contain?

Apo-Bromocriptine tablets 2.5mg contain the active ingredient bromocriptine mesylate, a dopamine agonist that is used to treat conditions caused by hyperprolactinaemia (high levels of prolactin), acromegaly (over production of growth hormone) and Parkinson's disease.

Treating hyperprolactinaemia (high levels of prolactin) with Apo-Bromocriptine

Apo-Bromocriptine tablets 2.5mg contain bromocriptine, a dopamine agonist that binds to dopamine receptors in various parts of the brain. Dopamine is a neurotransmitter (chemical that allows communication between nerve cells) produced by certain nerve cells (neurons) in the brain and it plays an important role in controlling hormone secretion. Prolactin is a hormone produced by the pituitary gland (a small gland in the base of the brain) and over-production of prolactin (hyperprolactinaemia) can result in several conditions, including suppression of the normal functioning of female and male reproductive processes, which can cause menstrual disorders and infertility; it can also cause over-production of breast milk in men and women (galactorrhoea). The dopaminergic (stimulates dopamine receptors) action of bromocriptine in Apo-Bromocriptine tablets 2.5mg activates dopamine-stimulated pathways in the brain, and one result of this is the inhibition of prolaction synthesis and secretion from the anterior pituitary gland. Inhibition of prolactin secretion by bromocriptine releases the suppression caused by high prolactin levels on normal functioning of the reproductive glands and also reduces breast milk production, which is dependent on prolactin to stimulate lactation. Apo-Bromocriptine tablets 2.5mg are used to treat menstrual disorders, infertility, galactorrhoea and to suppress milk production for medical conditions such as after a still birth; also to treat prolactinoma (a benign tumour of the pituitary gland that over-produces prolactin) causing the tumour to shrink and returning the levels of prolactin to normal.

Treating infertility with Apo-Bromocriptine

Apo-Bromocriptine tablets 2.5mg contain bromocriptine, a dopamine agonist that binds to dopamine receptors in various parts of the brain. Dopamine is a neurotransmitter (chemical that allows communication between nerve cells) produced by certain nerve cells (neurons) in the brain and it plays an important role in controlling production by the pituitary gland (a small gland in the base of the brain) of the hormone prolaction. High levels of prolactin (hyperprolactinaemia) can suppress the normal menstrual cycle by inhibiting the production of other hormones needed for ovulation and preparation for pregnancy and can cause infertility; these hormones are follicle-stimulating hormone (FSH) and gonadotropin-releasing hormone (GnRH). The dopaminergic (stimulates dopamine receptors) action of bromocriptine in Apo-Bromocriptine tablets 2.5mg activates dopamine-stimulated pathways in the brain, and one result of this is the inhibition of prolactin synthesis and secretion from the pituitary gland. Releasing the suppression caused by prolactin of hormones that control the menstrual cycle helps restore the hormonal balance needed for pregnancy and this is how Apo-Bromocriptine tablets 2.5mg are used to treat infertility.
