Gonadotrophin
releasing hormone agonists for hirsutism
Gonadotrophin releasing hormone agonists (GnRH) have been suggested
as potential treatments for hirsutism. The most common GnRH agonists
used are leuprolide acetate, buserelin and decapeptyl. GnRH agonists
are drugs that decrease ovarian steroid production and some studies
show that GnRH agonists could be very effective for treating hirsutism
where ovarian hyperandrogenism (too much androgen production by
the ovaries) is the problem. However, the effect of GnRH agonists
is on ovarian production so they are not very effective for hirsutism
where the root cause is over activity of the adrenal glands.
GnRH agonists are still primarily an experimental treatment. Some
studies suggest that addition of GnRH agonists to treatment using
antiandrogen drugs prolongs remission of hirsutism. GnRH agonists
have to be taken along with hormone replacement therapy (often called
"add back treatment") as the GnRH agonist shuts down ovarian
hormone production almost completely so while androgens are no longer
produced, neither are estrogens and progesterones. Hormone replacement
is particularly important as using GnRH agonists without estrogen
and progesterone supplements bone density decreases significantly.
The greatest barrier to wide spread use of GnRH agonists is that
the drugs are quite expensive compared to cyproterone acetate or
spironolactone.
