Generic Available

No


Pharmacological Index

Gonadotropin; Ovulation Stimulator


Use

Sequentially with hCG to induce ovulation and pregnancy in the infertile woman with functional anovulation or in patients who have previously received pituitary suppression; used with hCG in men to stimulate spermatogenesis in those with primary hypogonadotropic hypogonadism


Pregnancy Risk Factor

X


Contraindications

Primary ovarian failure, overt thyroid and adrenal dysfunction, abnormal bleeding, pregnancy, men with normal urinary gonadotropin concentrations, elevated gonadotropin levels indicating primary testicular failure


Warnings/Precautions

Advise patient of frequency and potential hazards of multiple pregnancy; to minimize the hazard of abnormal ovarian enlargement, use the lowest possible dose


Adverse Reactions

Male:

>10%: Endocrine & metabolic: Gynecomastia

1% to 10%: Erythrocytosis (shortness of breath, dizziness, anorexia, syncope, epistaxis)

Female:

>10%:

Endocrine & metabolic: Ovarian enlargement

Gastrointestinal: Abdominal distention

Local: Pain/rash at injection site

1% to 10%: Ovarian hyperstimulation syndrome

<1%: Thromboembolism, pain, febrile reactions


Overdosage/Toxicology

Symptoms of overdose include ovarian hyperstimulation


Drug Interactions

Clomiphene may amount of HMG needed to induce ovulation (Gonadorelin, Factrel®) should not be used with drugs that stimulate ovulation


Stability

Lyophilized powder may be refrigerated or stored at room temperature; after reconstitution inject immediately, discard any unused portion


Mechanism of Action

Actions occur as a result of both follicle stimulating hormone (FSH) effects and luteinizing hormone (LH) effects; menotropins stimulate the development and maturation of the ovarian follicle (FSH), cause ovulation (LH), and stimulate the development of the corpus luteum (LH); in males it stimulates spermatogenesis (LH)


Pharmacodynamics/Kinetics

Elimination: ~10% of dose is excreted in the urine unchanged


Usual Dosage

Adults: I.M.:

Female: 1 ampul/day (75 units of FSH and LH) for 9-12 days followed by 10,000 units hCG 1 day after the last dose; repeated at least twice at same level before increasing dosage to 2 ampuls (150 units FSH/150 units LH)

Repronex®: I.M., S.C.:

Infertile patients with oligo-anovulation: Initial: 150 int. units daily for the first 5 days of treatment. Adjustments should not be made more frequently than once every 2 days and should not exceed 75-150 int. units per adjustment. Maximum daily dose should not exceed 450 int. units and dosing beyond 12 days is not recommended. If patient's response to Repronex® is appropriate, hCG 5000-10,000 units should be given one day following the last dose of Repronex®.

Assisted reproductive technologies: Initial (in patients who have received GnRH agonist or antagonist pituitary suppression): 225 int. units; adjustments in dose should not be made more frequently than once every 2 days and should not exceed more than 75-50 int. units per adjustment. The maximum daily doses of Repronex® given should not exceed 450 int. units and dosing beyond 12 days is not recommended. Once adequate follicular development is evident, hCG (5000-10,000 units) should be administered to induce final follicular maturation in preparation for oocyte retrieval.


Administration

I.M. or S.C. (Repronex® ONLY) administration. The lower abdomen (alternating sides) should be used for subcutaneous administration.
