2.Product Description:

Goserelin is a synthetic analogue of a naturally occurring luteinizing-hormone releasing hormone (LHRH). Bioavailability is almost complete. Goserelin is poorly protein bound and has a serum elimination half-life of two to four hours in patients with normal renal function. The half-life increases with patients with impaired renal function. There is no significant change in pharmacokinetics in subjects with liver failure. After administration, peak serum concentrations are reached in about two hours. It rapidly binds to the LHRH receptor cells in the pituitary gland thus leading to an initial increase in production of luteinizing hormone and thus leading to an initial increase in the production of corresponding sex hormones. This initial flare may be treated by co-prescribing/co-administering an androgen receptor antagonist  (Casodex). Eventually, after a period of about 14-21 days, production of LH is greatly reduced due to receptor downregulation, and sex hormones are generally reduced to castrate levels

3.Product Application:

Goserelin acetate is used to treat hormone-sensitive cancers of the breast(in pre- and peri-menopausal women) and prostate, and some benign gynaecological disorders (endometriosis, uterine fibroids and endometrial thinning). In addition, goserelin is used in assisted reproduction and in the treatment of precocious puberty. It may also be used in the treatment of male-to-female transgender people and is favoured above other anti-androgens in some countries, such as the UK. It is available as a 1-month depot and a long-acting 3-month depot.

4.Side Effects:

Goserelin acetate may cause a temporary increase in bone pain and symptoms of prostatic cancer during the first few weeks of treatment. This is known as the tumour flare effect, and is the result of an initial increase inluteinizing hormone production, before the receptors are desensitised and hormonal production is inhibited. The symptoms will disappear, with hormonal inhibition. It is therefore advisable to co-treat with anantiandrogen during the first 2-3 weeks of goserelin treatment, particularly in patients with pre-existing bone symptoms.

A selection of fresh Red Fuji Apples with a diameter of 80mm.
Reducing blood fat: the Japanese fruit tree Institute's human test showed that eating two apples a day, 3 weeks later, the level of triglycerides in the blood of the subjects decreased by 21%, and the level of triglycerides was the culprit of vascular sclerosis. When apple pectin enters the body, it binds to bile acids, absorbs excess cholesterol and triglycerides like a sponge, and then passes them out of the body. At the same time, apple decomposition of acetic acid is conducive to the catabolism of these two substances. In addition, Apple's vitamins, fructose, magnesium and so on can also reduce their content.

Cancer prevention: the Hirosaki University in Japan has confirmed that polyphenols in apple can inhibit the proliferation of cancer cells. And a study in Finland is more exciting: the flavones contained in apples are an efficient antioxidant, not only the best blood vessel cleaning agent, but also the killer of cancer. If people eat more apples, the risk of lung cancer can be reduced by 46%, and the chance of other cancers can be reduced by 20%. The latest research from the National Institutes of health of France also tells us that Proanthocyanidins from apples can prevent colon cancer.
