Introduction to Buselin 0.5mg Injection

Buselin 0.5mg Injection is an anticancer drug belonging to the category of gonadotropin releasing hormone analogues, containing the active ingredient Buserelin. It is used in the treatment of advanced prostatic carcinoma(a type of prostate cancer that has spread outside of the prostate gland). It is also used in the treatment of endometriosis (is a condition in which the tissue that normally lines the inside of the uterus (endometrium) grows outside of it). This drug is also treated for the adjunctive use in ovulation induction.

If you experience any pain, swelling, feeling of tension in your stomach, feel sick, gain weight, diarrhoea, difficulty breathing, or passing less urine. These could be signs of a serious side effect called “Ovarian Hyperstimulation Syndrome (OHSS)”, so it is advised to inform your doctor immediately if all these symptoms exist. Incase of ectopic pregnancies, miscarriages or multiple pregnancies this drug can be used as adjunctive therapy. This drug may reduce the effect of drugs used to treat high blood pressure, and diabetes. It is recommended to monitor the blood pressure and blood glucose levels regularly to prevent complications. In addition, changes in blood lipids, increase in bilirubin levels, increase in serum liver enzymes levels (e.g. transaminases), leucopenia, thrombopenia have been observed with the use of this medicine. Talk to your doctor if you take any other medications or before using over-the-counter medicines or herbal products. Your doctor will evaluate the risk of interaction with this medication.

Breastfeeding should be avoided during the treatment with this drug as it may pass into breast milk in small amounts. This drug must not be given to premature or newborn babies because it contains benzyl alcohol which may cause toxic reactions and allergic reactions in infants and children up to 3 years old.

  • Advanced prostatic carcinoma

Therapeutic Effects of Buselin 0.5mg Injection

It works by reducing the production of certain hormones in the body. This drug specifically gets binding to and stimulating GnRH receptors in the pituitary gland, which is located at the base of the brain. This leads to a transient increase in the production and release of luteinizing hormone (LH) and follicle-stimulating hormone (FSH) from the pituitary gland. However, with continued use, this injection suppresses the production of LH and FSH, leading to a decrease in the production of testosterone in men and estrogen in women.

Inform your healthcare provider about all the medicines you take, including prescription medications, over-the-counter medications, nutritional or vitamin supplements, and herbal products.
