Buserelin may be used in the treatment of hormone-responsive cancers such as prostate cancer or breast cancer, estrogen-dependent conditions (such as endometriosis or uterine fibroids), and in assisted reproduction.
The substitution of glycine in position 6 by D-serine, and that of glycinamide in position 10 by ethylamide, leads to a nonapeptide with a greatly enhanced LHRH effect. The effects of buserelin on FSH and LH release are 20 to 170 times greater than those of LHRH. Buserelin also has a longer duration of action than natural LHRH. Investigations in healthy adult males and females have demonstrated that the increase in plasma LH and FSH levels persist for at least 7 hours and that a return to basal values requires about 24 hours. Clinical inhibition of gonadotropin release, and subsequent reduction of serum testosterone or estradiol to castration level, was found when large pharmacologic doses (50-500 mcg SC/day or 300-1200 mcg IN/day) were administered for periods greater than 1 to 3 months. Chronic administration of such doses of buserelin results in sustained inhibition of gonadotropin production, suppression of ovarian and testicular steroidogenesis and, ultimately, reduced circulating levels of gonadotropin and gonadal steroids. These effects form the basis for buserelin use in patients with hormone-dependent metastatic carcinoma of the prostate gland as well as in patients with endometriosis.

Absorption
Buserelin is water soluble and readily absorbed after subcutaneous injection (70% bioavailable). However, bioavailability after oral absorption. When administered correctly via the nasal route, it may be absorbed in the nasal mucosa to achieve sufficient plasma levels.
Route of Elimination
Buserelin and its inactive metabolites are excreted via the renal and biliary routes. In man it is excreted in urine at 50% in its intact form.
Volume of Distribution
Buserelin circulates in serum predominantly in intact active form. Preferred accumulation is preferentially in the liver and kidneys as well as in the anterior pituitary lobe, the biological target organ.
It is metabolized and subsequently inactivated by peptidase (pyroglutamyl peptidase and chymotrypsin-like endopeptidase) in the liver and kidneys as well as in the gastrointestinal tract. In the pituitary gland, it is inactivated by membrane-located enzymes.
The elimination half-life is approximately 50 to 80 minutes following intravenous administration, 80 minutes after subcutaneous administration and approximately 1 to 2 hours after intranasal administration.
Buserelin stimulates the pituitary gland's gonadotrophin-releasing hormone receptor (GnRHR). Buserelin desensitizes the GnRH receptor, reducing the amount of gonadotropin. In males, this results in a reduction in the synthesis and release of testosterone. In females, estrogen secretion is inhibited. While initially, there is a rise in FSH and LH levels, chronic administration of Buserelin results in a sustained suppression of these hormones.

ABOUT THIS PAGE
A Buserelin Acetate manufacturer is defined as any person or entity involved in the manufacture, preparation, processing, compounding or propagation of Buserelin Acetate, including repackagers and relabelers. The FDA regulates Buserelin Acetate manufacturers to ensure that their products comply with relevant laws and regulations and are safe and effective to use. Buserelin Acetate API Manufacturers are required to adhere to Good Manufacturing Practices (GMP) to ensure that their products are consistently manufactured to meet established quality criteria.

The Pharmaceuticals and Medical Devices Agency (PMDA) established the Japan Drug Master File (JDMF), also known as the Master File (MF), to permit Japanese and foreign manufacturers of drug substances, intermediates, excipients, raw materials, and packaging materials (‘Products’) to voluntarily register confidential information about the production and management of their products in Japan.
The Buserelin Acetate Drug Master File in Japan (Buserelin Acetate JDMF) empowers Buserelin Acetate API manufacturers to present comprehensive information (e.g., production methods, data, etc.) to the review authority, i.e., PMDA (Pharmaceuticals & Medical Devices Agency).
PMDA reviews the Buserelin Acetate JDMF during the approval evaluation for pharmaceutical products. At the time of Buserelin Acetate JDMF registration, PMDA checks if the format is accurate, if the necessary items have been included (application), and if data has been attached.

A Buserelin Acetate CEP of the European Pharmacopoeia monograph is often referred to as a Buserelin Acetate Certificate of Suitability (COS). The purpose of a Buserelin Acetate CEP is to show that the European Pharmacopoeia monograph adequately controls the purity of Buserelin Acetate EP produced by a given manufacturer. Suppliers of raw materials can prove the suitability of Buserelin Acetate to their clients by showing that a Buserelin Acetate CEP has been issued for it. The manufacturer submits a Buserelin Acetate CEP (COS) as part of the market authorization procedure, and it takes on the role of a Buserelin Acetate CEP holder for the record. Additionally, the data presented in the Buserelin Acetate CEP (COS) is managed confidentially and offers a centralized system acknowledged by numerous nations, exactly like the Buserelin Acetate DMF.
A Buserelin Acetate CEP (COS) is recognised by all 36 nations that make up the European Pharmacopoeia Convention. Buserelin Acetate CEPs may be accepted in nations that are not members of the Ph. Eur. at the discretion of the authorities there.

A Buserelin Acetate written confirmation (Buserelin Acetate WC) is an official document issued by a regulatory agency to a Buserelin Acetate manufacturer, verifying that the manufacturing facility of a Buserelin Acetate active pharmaceutical ingredient (API) adheres to the Good Manufacturing Practices (GMP) regulations of the importing country. When exporting Buserelin Acetate APIs or Buserelin Acetate finished pharmaceutical products to another nation, regulatory agencies frequently require a Buserelin Acetate WC (written confirmation) as part of the regulatory process.

National Drug Code is a comprehensive database maintained by the FDA that contains information on all drugs marketed in the US. This directory includes information about finished drug products, unfinished drug products, and compounded drug products, including those containing Buserelin Acetate as an active pharmaceutical ingredient (API).
The FDA updates the NDC directory daily. The NDC numbers for Buserelin Acetate API and other APIs are published in this directory by the FDA.
The NDC unfinished drugs database includes product listing information submitted for all unfinished drugs, such as active pharmaceutical ingredients (APIs), drugs intended for further processing and bulk drug substances for compounding.
Pharmaceutical companies that manufacture Buserelin Acetate as an active pharmaceutical ingredient (API) must furnish the FDA with an updated record of all drugs that they produce, prepare, propagate, compound, or process for commercial distribution in the US at their facilities.
The NDC directory also contains data on finished compounded human drug products that contain Buserelin Acetate and are produced by outsourcing facilities. While these outsourcing facilities are not mandated to assign a Buserelin Acetate NDC to their finished compounded human drug products, they may choose to do so.
