Rapamune general information
What is Rapamune used for?
Rapamune tablets 1mg are used to help prevent organ rejection of a transplanted kidney, which is the last resort treatment for kidney failure.
The kidneys lie towards your back and on each side of your spine. They are vital organs for many body functions, and kidney failure is a life-threatening condition. The main job performed by the kidneys is to remove toxins from the blood, filter out waste products of metabolism like urea and creatinine, and remove excess fluids, turning them into urine to be excreted. The kidneys also keep a constant balance in the electrolyte and water content of your body fluids by regulating essential ions in the blood and urine like calcium, sodium, and potassium. The kidneys produce several hormones. Renin regulates salt and water balance, which helps control blood pressure. Erythropoietin stimulates the bone marrow to make red blood cells. Calcitriol, also known as Vitamin D regulates calcium levels and supports strong bones.
If the function of the kidneys is impaired in any way, this can lead to kidney disease and ultimately kidney failure. Kidney failure or end-stage renal failure is when most of your kidney function has been lost. It can develop quickly or over a long time due to chronic kidney disease.
The main causes of kidney failure are related to diabetes and high blood pressure, both of which cause damage to the kidney cells. Other causes include conditions like glomerulonephritis, which is inflammation and damage to the filtering structures of the kidneys called the glomeruli. Kidney stones, tumours and kidney infection can also cause kidney damage. Also, family history and genetics are a factor in developing kidney disease.
Symptoms of kidney failure include changes in amount and frequency of urination, blood in the urine, lethargy, loss of appetite, nausea, vomiting, puffiness and swelling of the ankles and legs (oedema), pain in the area of your kidneys, lack of concentration, shortness of breath, and high blood pressure. The major cause of death if kidney failure cannot be resolved is heart disease.
Kidney failure cannot be cured but can be treated by dialysis, which is the process of filtering the blood by a dialysis machine. If this does not work to restore kidney function, the only other choice is a kidney transplant. It is essential to find a close match to your own tissue type to prevent the kidney transplant being rejected. However, your immune system will attack any foreign cell, and even a close match may not prevent your immune cells from destroying the transplanted kidney. Rapamune tablets 1mg are used to help prevent organ rejection of a transplanted kidney.
How does Rapamune work?
Rapamune tablets 1mg contain sirolimus, also known as rapamycin, an immunosuppressant that is used to prevent organ rejection of a transplanted kidney. An immunosuppressant drug works by interacting with cells of the immune system to reduce and weaken the immune response. When the immune system recognises a cell as foreign, specific immune cells, are activated and proliferate. T cells produce chemicals like interleukins that help progress the immune response, and B cells produce antibodies to destroy the foreign cells.
T cell activation takes place in two stages. Some immunosuppressant drugs like ciclosporin and tacrolimus block the first phase of T cell activation. Sirolimus in Rapamune tablets 1mg blocks the second phase of T cell activation. It first binds to a specific protein inside T cells called FKBP-12 forming a complex. This complex blocks the activation of an enzyme called mammalian Target Of Rapamycin (mTOR). mTOR is critical to the complex messaging process that takes place within the T cells and allows them to complete the activation process. The action of sirolimus in Rapamune tablets 1mg blocks the replication of T cells and prevents them mounting an immune response against the transplanted kidney.
