Pharmacodynamics preparation Gonal F

The drug is a recombinant human FSH stimulates the growth and development of follicles. Get FSH by genetic engineering of a Chinese hamster ovary cells. It has gonadotropin action: promotes the growth and maturation of follicles develop several follicles in the case of controlled ovarian hyperstimulation during the program of assisted reproductive technology (ART).

The clinical study, as well as numerous positive reviews of Gonal F for the ART program and ovulation induction showed greater efficiency follitropin alfa compared with urinary FSH. Compared with urinary FSH it contributes to the process of maturing follicles, reduce the cumulative dose and duration of treatment, reducing the risk of unwanted ovarian hyperstimulation.

Thus, during the appointment ART Gonal F by treatment instructions will be shorter, and the number of oocytes retrieved - as compared with urinary FSH.

It is also proved that follitropin alpha promotes stimulation of steroidogenesis and follicular development in women with suppression of endogenous gonadotropins, despite the low level of LH, inaccessible to measurement.

Sometimes there is a severe form of ovarian hyperstimulation syndrome, is rare - complications OHSS, ectopic (mainly women with diseases of the fallopian tubes), or multiple pregnancy.
  • the cardiovascular system. Very rarely can develop thromboembolism associated with severe OHSS.
  • Local reactions. Very often, patients complain of occurrence of injection site reactions (redness, swelling, pain, bruising).
