Qlaira is a combined contraceptive, low-dose, intended for oral use. The preparation contains both estrogenic and progestational components, so that the tablets are well tolerated by patients in 99% of cases. In addition to active tablets, the package contains 2 more inactive tablets, which makes it possible to continuously take the drug. The effect of the contraceptive is achieved due to the oppression of ovulation, increasing the density of cervical mucus, as well as reducing the sensitivity of the endometrium of the uterus to the blastocyst (the initial stage of development of the embryo).In addition to the main effect, this drug stimulates a decrease in the intensity and duration of the menstrual cycle, relieves the symptoms of PMS and minimizes pain symptoms.
Estrogen in Qlaira is estradiol valerate - ester of human 17β-estradiol (1 mg of estradiol valerate corresponds to 0.76 mg of 17β-estradiol). This estrogen differs from ethinylestradiol or its precursor to mestranol used in other COCs and containing the ethyl group 17a, which causes more stable metabolic activity, but also affects the liver.Dienogest (DNG) is a progestogen with previous clinical trials. It has a pronounced effect on the endometrium. Structurally comes from nortestosterone, has the characteristics of nortestosterone and progestogen derivatives. DNG does not have androgenic activity, but has anti-androgenic activity.Pharmacokinetics
Estradiol valerateAbsorption: After oral administration of estradiol, the valerate is completely absorbed by the intestinal mucosa. After initial absorption, E2V is hydrolyzed to produce E2 and valeric acid by a metabolic process in the mucosa of the gastrointestinal tract and liver.Metabolism: metabolism occurs in the mucosa of the gastrointestinal tract and liver. Estradiol valerate is undergoing extensive changes in the first passage of metabolism, which leads to an increase in the concentration of estradiol and its metabolites in the blood serum. In the metabolism, approximately 95% of the oral dose of estradiol valerate is involved before it enters the systemic circulation, so the bioavailability of E2V is about 3-5%. Metabolism E2 in the intestinal mucosa and liver leads to conversion to estrone (E1) and estriol (E3). Both E1 and E3 are metabolized in sulfate and glucuronide forms. These forms of limited cell penetration partly explain their low effectiveness. Estrone (E1) is converted to estrone sulfate (E1-S) by the estrogen sulfotransefare and both can be converted back to E2. Since most of the absorbed E2 is converted to E1 and E1-S, E2 levels are stabilized. Estrogens undergo further oxidation with the help of liver cytochrome P450, affecting the pathways of CYP3A4 and 1A2 until complete elimination.Distribution: 5% of the oral dose of E2V achieve systematic circulation. E2 is associated with 38% of the mandatory sex hormone globulin (SHBG), 60% albumin and - 3% circulates in free form. The approximate volume of the distribution is ~ 1.2 l / kg. The serum concentration of E2 remains stable during the 28-day treatment period in the range of 0.0336-0.0647 ng / ml due to the stable state between E2-E1-E1-S. Recirculation includes E1-S and estrone glucuronide. The half-life of estradiol is 1.5 hours, the final half-life of estradiol after oral administration is 13-20 hours and depends on the recycling of estrogen sulfate.Excretion: Estradiol and its metabolites are mainly excreted in the urine. 10% is excreted with feces.DienogestAbsorption: DNG is almost completely absorbed after oral administration and has a high bioavailability (91%). There is no clinically established effect on the rate and extent of absorption of DNG concomitant food intake.Distribution: DNG has a distribution volume of 46L. It circulates in serum with serum albumin (90%) and 9% in the form of free and bioavailable elements. Concentration in serum of DNG in steady state is: min 11.8ng / ml max 82.9ng / ml.Metabolism: The half-life of plasma is 12 hours. The substance is almost completely metabolized by cytochrome P450, isoforms of CYP3A4 in pharmacologically inactive metabolites.Excretion: DNG and its metabolites are excreted mainly by the kidneys. 86% of the hormone and its metabolites are excreted after 6 days.
