For long-acting progesterone, intramuscular injection in muscle
tissue gradually slow release and play a long-acting contraceptive
effect. Its main role is to inhibit ovulation, can still affect the
consistency of cervical mucus and inhibit endometrial growth and
development. After 5 to 7 days after injection of blood
concentration peak, t1 / 27.5 ~ 22.5 days. A single intramuscular
injection of 200mg, the role can be maintained for 2 to 3 months,
can be used as a two-month long-acting contraceptives. This product
and estradiol valerate combination of compound norethindrone
injection, the monthly injection of a role can be maintained for 30
days, the control effect of the menstrual cycle was significantly
better than the single use of norethisterone norethisterone needle.
Mechanism of action is multi-link and multi-faceted, and because of
its ingredients, formulations, dosage and usage vary. Such as
estrogen and progesterone compound to inhibit ovulation, low-dose
progesterone to obstruct the fertilization-based, high-dose
progesterone to anti-implantation based. The classification of the
above application mechanism is relative.
1, to inhibit ovulation-based steroidal sex hormones. Estrogen and
progesterone after oral absorption of plasma concentration
increased by negative feedback inhibition of hypothalamic
gonadotropin-releasing hormone secretion; in addition to blood sex
hormones on the anterior pituitary also has a direct inhibitory
effect, can reduce the anterior pituitary gonadotropin secretion ,
Follicle stimulating hormone (FSH) and luteinizing hormone (LH) the
amount of blood were reduced, due to inhibition of FSH secretion,
hinder the growth and maturation of the follicle, there is no
mature follicle for ovulation, also abolished ovulation estrogen
peak . As the mid-menstrual LH peak disappears, ovulation process
2, to impede the steroid-based fertilization hormone. Small doses
of progesterone after oral administration, change the physical and
chemical properties of cervical mucus, hinder fertilization.
Progesterone can inhibit the secretion of cervical mucus, mucus to
reduce the viscosity but increased, increased cell content, is not
conducive to sperm penetration, so that sperm difficult to pass, to
impede the effect of fertilization. In the case of progesterone is
dominant, sperm capacitation can be inhibited, loss of
fertilization ability, thus affecting fertilization. In the entire
menstrual cycle, continuous use of small doses of progesterone, can
hinder fertilization, the advantage is not containing estrogen,
fewer side effects, but the effect of contraceptive estrogen and
progesterone than the compound, and the higher incidence of
irregular bleeding . Has been less.
(1) inhibition of ovulation, to promote endometrial hyperplasia, in
order to facilitate the implantation of fertilized eggs and reduce
uterine muscle excitability, to ensure the safety of pregnancy.
(2) to promote the growth of breast acinar, in preparation for
lactation. Improve body temperature and relax the blood vessels and
digestive smooth muscle.
(3) As the progesterone androgen, estrogen, adrenal cortex hormones
and other important intermediates in biosynthesis, so to varying
degrees with the role of various types of hormones. Some synthetic
estrogen and progesterone and its analogues in the clinical mainly
used for infertility, threatened abortion and habitual abortion,
endometriosis, functional uterine bleeding, amenorrhea, menopausal
syndrome, bone Loose, etc., and can be used for endometrial cancer
and prostate cancer and cancer chemotherapy increased white blood
On the impact of menstruation
reduced by the amount or amenorrhea. Taking norethindrone
gynecology often occurs after this situation is due to drug
inhibition of ovulation, ovarian secretion of estrogen less, less
estrogen content of drugs, the endometrium can not grow normally,
endometrial thin, so by the amount of reduction, Even menopause.
The reduction in the amount of no effect on health. If the course
of medication for 2 months of menopause should be discontinued,
switch to other measures of contraception, most of them can return
to normal. Taking norethindrone gynoprostenol often appears after
taking menopause, this time available progesterone medications such
as norethindrone, or injection of norethindrone, can also be used
short-acting contraceptives 2, 2 per night, And even served 5 to 6
days. Generally within one week after stopping the menstrual
breakthrough bleeding. Such as medication during the bleeding,
occurred in the leakage medication after. Although few people have
missed medication can also occur vaginal bleeding. If occurred in
the first half of the menstrual cycle, estrogen may be due to lack
of service can be added norethindrone 0.005 ~ 0.015mg, once a day,
until served 22 so far. If occurred in the second half of the
menstrual cycle, is due to lack of progesterone, can be added
short-acting contraceptive tablets 1 or 2 1, until served 22 so
far. If the amount of bleeding, such as menstrual cramps, menstrual
cramps can be treated immediately withdrawal, in the first 5 days
of withdrawal, and then start the next month's medication.
by the amount increased, extended menstruation. Often occur in the
service norethindrone norethisterone, more bleeding when available
hemostatic, if necessary, injection of testosterone propionate. If
the amount of menstrual continued to increase, continuous bleeding
for more than 3 months, you should stop taking long-acting oral
contraceptives, modified to serve short-acting drugs. Application
of long-acting injection of norethindrone, often menstrual
irregularities, such as prolonged menstrual period, by the amount
of shortening, irregular bleeding or amenorrhea, more common in the
first 3 months of treatment. If you insist on using, the future
will gradually return to normal. In the event of bleeding can be
