Genkort (Hydrocortisone 10mg) Tablets (Sourced from Turkey)

Genkort general information

What is Genkort used for?

The adrenal glands sit just above the kidney.  They are vital endocrine (hormone-producing) organs that regulate many body functions, including metabolism, blood pressure, our response to stress, and our immune system.  If the adrenal glands don’t produce enough hormones, this condition is known as adrenal insufficiency and can cause serious health problems.  Genkort tablets 10mg are used as hormone replacement therapy for treating adrenal insufficiency. 

Adrenal gland hormones

The hormones produced by the adrenal glands include cortisol, a glucocorticoid commonly known as the stress hormone that plays an essential role in metabolism.  Cortisol regulates the way the body uses fats, proteins, and carbohydrates, and increases blood sugar.  It is also a potent anti-inflammatory and has regulatory effects on blood pressure and bone formation.  The amount of cortisol released by the adrenal gland, is controlled by Adrenocorticotropic Hormone (ACTH}.  The pituitary gland in the brain is the control centre for many endocrine (hormone) systems.  It produces ACTH in response to low cortisol levels in the blood. 

Aldosterone is a mineralocorticoid hormone that regulates blood volume and salt content.  These are both important factors in regulating blood pressure. 

Adrenaline (epinephrine) and noradrenaline (norepinephrine) are catecholamines.  They trigger the flight or fight response and work by increasing heart rate, blood flow to the muscles and brain, and glucose metabolism to supply a rapid energy source.  

The adrenal glands also produce a precursor sex hormone (dehydroepiandrosterone or DHEA) that can be converted into oestrogen in the ovaries or androgens in the testes.

Adrenal insufficiency

Addison’s disease is the most common form of primary adrenal insufficiency.  It is an autoimmune disease, where the immune system attacks body tissues, mistaking them as foreign.  The adrenal cortex is the outer part of the adrenal gland and is where cortisol is produced.  The immune system gradually destroys the cells of the adrenal cortex, resulting in low cortisol levels.  Another common cause of adrenal insufficiency is when the pituitary gland does not produce enough ACTH to stimulate the production of cortisol by the adrenal gland.  This is known as secondary adrenal insufficiency.  It can be due to a pituitary tumour, some medications such as prednisone, or surgical removal of the pituitary. 

Other conditions affecting the production of cortisol include congenital adrenal hyperplasia, which is an inherited disease, where an essential enzyme for cortisol production is missing.  Also an infection and adrenal gland tumour.

Symptoms of adrenal insufficiency

Symptoms of adrenal insufficiency include abdominal pain, nausea, vomiting, weight loss, poor appetite, fatigue, muscle weakness and dizziness due to low blood pressure.  Another symptom of Addison’s disease is darkening of the skin.

Genkort tablets contain a steroid that is similar to cortisol, a naturally occurring steroid hormone produced by the adrenal glands.  Therefore, it can also be used as replacement therapy in endocrine (hormone) conditions caused by low cortisol levels. 

Other uses for Genkort

Aminoglutethimide is a medication used to treat breast or prostatic cancer, and it causes an increase in ACTH.  Genkort is used in conjunction with aminoglutethimide to inhibit ACTH secretion.

How does Genkort work?

Genkort tablets 10mg contain hydrocortisone, a synthetic corticosteroid hormone, that is used as hormone replacement therapy to substitute for low cortisol levels.  Hydrocortisone in Genkort tablets 10mg has similar properties to the naturally produced hormone cortisol, and works by binding to a specific glucocorticoid receptor that is expressed (made available) inside most cells of the body.  Interaction between hydrocortisone and its receptor regulates the transcription of particular genes (the process where DNA is converted into RNA, the template for protein synthesis).  These genes control many aspects of development, metabolism, and the immune response.  Hydrocortisone in Genkort tablets 10mg restores essential corticosteroid hormone levels to normal.  This helps relieve symptoms of adrenal insufficiency.

What does Genkort contain?

Genkort tablets 10mg contain the active ingredient hydrocortisone, used as hormone replacement therapy to increase low cortisol levels.  They also contain lactose monohydrate, magnesium stearate, maize starch, povidone, and purified talc.
