Human Chorionic Gonadotrophin
Indications
In the female: Ovulation induction in infertility due to anovulation or impaired follicle-ripening. Preparation of follicles for puncture in controlled ovarian hyperstimulation programs (ART). Luteal phase support. Threatened and habitual abortion In the male: Hypogonadotropic hypogonadism (also cases of idiopathic dysspermias have shown a positive response to gonadotropins). Delayed puberty associated with insufficient gonadotropic pituitary function. Cryptorchidism, (not due to anatomical obstruction) Used to treat oligospermia
Pharmacology
Pharmacodynamic Properties: Highly Purified Human Chorionic Gonadotrophin has LH activity. LH is indispensable in normal female and male gamete growth and maturation, and gonadal steroid production. In the female: Human Chorionic Gonadotrophin is given as a substitute for the endogenous mid-cycle LH surge to induce the final phase of follicular maturation, leading to ovulation. Human Chorionic Gonadotrophin is also given as a substitute for endogenous LH during the luteal phase. In the male: Human Chorionic Gonadotrophin is given to stimulate Leydig cells to promote the production of testosterone. Pharmacokinetic Properties: Maximal Human Chorionic Gonadotrophin plasma levels will be reached approximately six hours after a single injection of Human Chorionic Gonadotrophin . Human Chorionic Gonadotrophin is for approximately 80 percent metabolized, predominantly in the kidneys. Following intramuscular injection (IM) the apparent elimination half-life of Human Chorionic Gonadotrophin is about 2 days. On basis of the recommended dose regimens and elimination half-life, accumulation does not occur.
Dosage Administration
After addition of the solvent to the freeze-dried substance, the reconstituted Human Menopausal Gonadotrophin solution should be slowly administered intramuscularly. In the female: Ovulation induction and preparation of follicles for puncture: Usually, one injection of 5000- 10000IU Human Menopausal Gonadotrophin to complete treatment with an FSH-containing preparation. Luteal phase support: Two repeat injections of 2500 to 5000IU. Each may be given within nine days following ovulation or embryo transfer (for example on day 3, 6 and 9 after ovulation induction). Threatened & habitual abortion: 5000IU Human Menopausal Gonadotrophin will be given as deep intramuscular injection twice weekly from the time of diagnosis (all before the 7th week of gestation) In the male: Hypogonadotropic hypogonadism: 2500 to 5000 IU Human Menopausal Gonadotrophin, two times per week. If the main complaint is sterility, additional doses of an FSH-containing (50IU FSH) are to be administered daily or two to three times a week. This treatment should be continued for at least three months before any improvement in spermatogenesis can be expected. During this treatment testosterone replacement therapy should be suspended. Once achieved, the improvement may in some cases be maintained by Human Menopausal Gonadotrophin alone.
Contraindications
Known or suspected androgen-dependent tumours, such as prostatic carcinoma or breast carcinoma in the male.
Side Effects
Allergic reactions have occasionally been reported with the use of urinary gonadotrophin preparations. These mostly involve local reactions such as pain and rash at the injection site, and generalized reactions such as rash and fever. In the female: Unwanted ovarian hyperstimulation syndrome. Which is Characteristic symptoms of unwanted ovarian hyperstimulation and the ovarian hyperstimulation syndrome are included under 'Special warnings and special precautions for use'. In the Male: Water and sodium retention is occasionally seen after administration of high dosages; this is regarded as a result of excessive androgen production. Treatment with Human Chorionic Gonadotrophin leads to increased androgen production. Therefore: Patients with latent or overt cardiac failure, renal dysfunction, hypertension, epilepsy or migraine (or a history of these conditions) should be kept under close medical supervision, since aggravation or recurrence may occasionally be induced as a result of increased androgen production. Human Chorionic Gonadotrophin should be used cautiously in prepubertal boys to avoid premature epiphyseal closure or precocious sexual development. Skeletal maturation should be monitored regularly.
Pregnancy And Lactation
Pregnancy Category X. Studies in animals or human beings have demonstrated foetal abnormalities or there is evidence of foetal risk based on human experience or both, and the risk of the use of the drug in pregnant women clearly outweighs any possible benefit. The drug is contraindicated in women who are or may become pregnant. Use in lactation: It must not be used during lactation
Therapeutic
Pediatric Use: Induction of androgen secretion by HCG may induce precocious puberty in pediatric patients treated for cryptorchidism. Therapy should be discontinued if signs of precocious puberty occur. Geriatric Use: Clinical studies of Chorionic gonadotropin for injection did not include subjects aged 65 and over.
Storage Conditions
The acute toxicity of urinary gonadotropin preparations has been shown to be very low. There are no symptoms of an acute parenteral overdose known in humans.
