In this article, you can read the instructions for using the drug Prog. There are reviews of visitors to the site - consumers of this medication, as well as opinions of doctors of specialists on the use of Progestogel in their practice. A big request is to actively add their feedback on the drug: the medicine helped or did not help get rid of the disease, which were observed complications and side effects, possibly not declared by the manufacturer in the annotation. Analogues of the Prohorgel in the presence of existing structural analogs. Use to treat diffuse fibrocystic mastopathy and mastodynia in adults, children, as well as during pregnancy and breast-feeding.
Prog - Progestogen for external use. The active component of the drug is progesterone.
The action of Progesterone is based on the blocking of estrogen receptors, which improves the absorption of fluid from the tissues and reduces the compression of the milk ducts, as well as the blocking of prolactin receptors in the breast tissue, which leads to a decrease in lactopoiesis.
Local use of the drug, creating a high concentration of progesterone in the area of application, does not have a systemic effect and avoids undesirable side effects.
The mechanism of action of the Projug is based on an increase in the concentration of progesterone in the tissues of the breast. Progesterone reduces the expression of estrogen receptors in the breast tissue, and also reduces the local level of active estrogens by stimulating the production of enzymes (17-beta-hydroxysteroid dehydrogenase and estrone sulfotransferase) that oxidize estradiol to a less active estrone (binding the latter to enzymes that convert it to inactive estrone sulfate).
Thus, progesterone limits the proliferative effect of estrogens on breast tissue.
Progesterone also has a small sodium diuretic effect due to oppression of tubular reabsorption and an increase in cell filtration, preventing fluid retention in secretory transformations of the glandular component of the mammary glands and, as a consequence, the development of pain syndrome (mastalgia or mastodynia).
Along with this, the transdermal method of administering the gestagene also allows to influence the condition of the glandular epithelium and the vasculature, as a result of which the permeability of capillaries decreases, the degree of swelling of the mammary gland tissues decreases, the symptoms of mastalgia disappear.
Composition
Progesterone natural micronized + auxiliary substances.
Pharmacokinetics
In the transdermal mode of application, the Progestogen reaches the breast tissue without breaking down in the liver and without adversely affecting systemic effects on the body.
Absorption of progesterone for dermal application is about 10% of the dose. The study of the serum concentrations of prolactin, estradiol and progesterone in the treatment with Progestogen showed that after 1 hour after application, when the maximum absorption in the tissue is observed, the level of hormones practically does not change.
Cumulative applications on the area of the mammary glands make it possible to create a high concentration in the range of action (10 times higher than in the systemic blood flow) of the drug when the applied dose is reduced.
The drug is re-metabolized in the liver with the formation of conjugates with glucuronic and sulfuric acids.
It is excreted by the kidneys - 50-60%, with bile - more than 10%. The amount of metabolites excreted by the kidneys varies depending on the phase of the yellow body.
Indications
- mammalgia;
- diffuse fibrocystic mastopathy.
Forms of release
Gel for external use 1% (sometimes mistakenly called ointment or cream).
Instructions for use and how to use them
It is necessary to apply 1 application of gel (2.5 g of gel, contains 0.025 g of progesterone) to the skin of the mammary glands by the applicator-dispenser until it is fully absorbed 1-2 times daily or in the 2nd phase (from the 16th to the 25th day) of the menstrual period cycle. The course of treatment - up to 3 cycles.
Side effect

Application in pregnancy and lactation

The use of the drug during pregnancy and during lactation is possible only if the intended benefit to the mother exceeds the potential risk to the fetus and the baby.
special instructions

The drug should be applied to the skin of the breast with the applicator-doser, without rubbing or massaging the mammary glands.
After applying the cream, avoid direct sunlight.
Caution should be used in cases of liver failure, kidney failure, bronchial asthma, epilepsy, migraine, depression,hyperlipoproteinemia, ectopic pregnancy, abortion in the course, inclination to thrombosis, acute forms of phlebitis or thromboembolic diseases, bleeding of unclear etiology from the vagina; porphyria, arterial hypertension, diabetes mellitus.

Repeated treatment may be prescribed only after consultation with a doctor.
