Indications and Usage:
Indications and usage: hcg has not been demonstrated to be effective adjunctive therapy in the treatment of obesity. there is no substantial evidence that it increases weight loss beyond that resulting from caloric restriction, that it causes a more attractive or âânormalââ distribution of fat, or that it decreases the hunger and discomfort associated with calorie-restricted diets. prepubertal cryptorchidism not due to anatomical obstruction. in general, hcg is thought to induce testicular descent in situations when descent would have occurred at puberty. hcg thus may help predict whether or not orchiopexy will be needed in the future. although, in some cases, descent following hcg administration is permanent, in most cases, the response is temporary. therapy is usually instituted between the ages four and nine. selected cases of hypogonadotropic hypogonadism (hypogonadism secondary to a pituitary deficiency) in males. induction of ovulation and pregnancy in the ano

Warnings:
Warnings: hcg should be used in conjunction with human menopausal gonadotropins only by physicians experienced with infertility problems who are familiar with the criteria for patient selection, contraindications, warnings, precautions and adverse reactions described in the package insert for menotropins. the principal serious adverse reactions are: (1) ovarian hyperstimulation, a syndrome of sudden ovarian enlargement, ascites with or without pain and/or pleural effusion, (2) rupture of ovarian cysts with resultant hemoperitoneum, (3) multiple births and (4) arterial thromboembolism. anaphylaxis and other hypersensitivity reactions have been reported with urinary-derived hcg products.
Dosage and Administration:
Dosage and administration: intramuscular use only the dosage regimen employed in any particular case will depend upon the indication for use, the age and weight of the patient and the physicianâs preference. the following regimens have been advocated by various authorities. prepubertal cryptorchidism not due to anatomical obstruction 4,000 usp units three times weekly for three weeks. 5,000 usp units every second day for four injections. 15 injections of 500 to 1,000 usp units over a period of six weeks. 500 usp units three times weekly for four to six weeks. if this course of treatment is not successful, another is begun one month later giving 1,000 usp units per injection. selected cases of hypogonadotropic hypogonadism in males 500 to 1,000 usp units three times a week for three weeks, followed by the same dose twice a week for three weeks. 4,000 usp units three times weekly for six to nine months, following which the dosage may be reduced to 2,000 usp units three times weekly

Description:
Description: human chorionic gonadotropin (hcg), a polypeptide hormone produced by the human placenta, is composed of an alpha and a beta sub-unit. the alpha sub-unit is essentially identical to the alpha sub-units of the human pituitary gonadotropins, luteinizing hormone (lh) and follicle-stimulating hormone (fsh), as well as to the alpha sub-unit of human thyroid-stimulating hormone (tsh). the beta sub-units of these hormones differ in amino acid sequence. chorionic gonadotropin is obtained from the human pregnancy urine. it is standardized by a biological assay procedure. chorionic gonadotropin for injection, usp is available in multiple dose vials containing 10,000 usp units with accompanying bacteriostatic water for injection for reconstitution. when reconstituted with 10 ml of the accompanying diluent each vial contains: chorionic gonadotropin 10,000 units mannitol 100 mg benzyl alcohol 0.9% water for injection q.s. buffered with dibasic sodium phosphate and monobasic sodium phosphate. hydrochloric acid and/or sodium hydroxide may have been used for ph adjustment (6.0-8.0). nitrogen gas is used in the freeze drying process.
Clinical Pharmacology:
Clinical pharmacology: the action of hcg is virtually identical to that of pituitary lh, although hcg appears to have a small degree of fsh activity as well. it stimulates production of gonadal steroid hormones by stimulating the interstitial cells (leydig cells) of the testis to produce androgens and the corpus luteum of the ovary to produce progesterone. androgen stimulation in the male leads to the development of secondary sex characteristics and may stimulate testicular descent when no anatomical impediment to descent is present. this descent is usually reversible when hcg is discontinued. during the normal menstrual cycle, lh participates with fsh in the development and maturation of the normal ovarian follicle, and the mid-cycle lh surge triggers ovulation. hcg can substitute for lh in this function. during a normal pregnancy, hcg secreted by the placenta maintains the corpus luteum after lh secretion decreases, supporting continued secretion of estrogen and progesterone and prev
