It is used for contraception or to treat such conditions as secondary amenorrhea, abnormal uterine bleeding, and endometriosis. As an oral contraceptive, norethindrone is available as either a single agent or in combination with an estrogen. Progestin-only formulations or "mini-pills" of norethindrone are not widely used because of increased incidence of certain side effects such as irregular, unpredictable spotting and breakthrough bleeding. Progestin-only contraceptives have a higher risk of failure compared to estrogen-progestin combinations because of variable suppression of follicle-stimulating hormone (FSH) and luteinizing hormone (LH) in low-dose progestin-only regimens. Norethindrone was approved by the FDA in 1961. An implant dosage form for contraception is under investigation.<br> <a name="mec"></a><strong>Mechanism of Action:</strong> The primary contraceptive effect of progestins involves the suppression of the midcycle surge of LH. The exact mechanism of action, however, is unknown. At the cellular level, progestins diffuse freely into target cells and bind to the progesterone receptor. Target cells include the female reproductive tract, the mammary gland, the hypothalamus, and the pituitary. Once bound to the receptor, progestins slow the frequency of release of gonadotropin releasing hormone (GnRH) from the hypothalamus and blunt the pre-ovulatory LH surge, thereby preventing follicular maturation and ovulation. Overall, progestin-only contraceptives prevent ovulation in 70—80% of cycles, however, the clinical effectiveness ranges 96—98%. This suggests that additional mechanisms may be involved. Other actions of norethindrone include alterations in the endometrium that can impair implantation and an increase in cervical mucus viscosity which inhibits sperm migration into the uterus. The administration of norethindrone to women with adequate estrogen production transforms the uterus from a proliferative to a secretory phase. Norethindrone has minimal estrogenic, androgenic, and anabolic activity.<br> <a name="phar"></a><strong>Pharmacokinetics:</strong> Norethindrone is administered orally. Pharmacokinetic parameters for norethindrone are poorly understood. Norethindrone is moderately bound to plasma proteins. It is hepatically metabolized and eliminated in both the urine and the feces. The elimination half-life of norethindrone is about 10 hours.</p> <p> </p> <p>aygestin as birth control<br/> aygestin effectiveness<br/> side effects of stopping aygestin<br/> aygestin in uterine bleeding<br/> progestin aygestin<br/> aygestin and acne<br/> treating ovarian cysts with aygestin<br/> aygestin period<br/> medicine aygestin<br/> aygestin and polyp<br/> a href buy aygestin<br/> aygestin and endometriosis<br/> aygestin used for<br/> side effects aygestin<br/> does aygestin stop your period<br/> side effects of drug aygestin<br/> buying aygestin<br/> aygestin and weight gain<br/> birth defects from aygestin<br/> how does aygestin stop your periods<br/> amount of progestin in aygestin<br/> stopping aygestin<br/> aygestin taper<br/> should i take aygestin<br/> aygestin safety<br/> side effects of aygestin<br/> hormone therapy aygestin<br/> aygestin therapy<br/> aygestin and problems sleeping<br/> aygestin pregnancy test<br/> taking aygestin and gaining weight<br/> getting pregnant while on aygestin<br/> is aygestin safe<br/> natural progesterone vs aygestin<br/> aygestin preventing periods<br/> aygestin<br/> aygestin effects side<br/> lupron depot aygestin endometriosis<br/> how does aygestin work<br/> is there a substitute for aygestin<br/> aygestin and blood clot<br/> breakthrough bleeding while on aygestin<br/> aygestin endometriosis<br/> drug info for aygestin<br/> benefits of aygestin therapy<br/> aygestin weight gain<br/> medication called aygestin<br/> aygestin side effects<br/> norethindrone acetate aygestin<br/> does aygestin cause acne<br/> aygestin effective at preventing pregnancy<br/> aygestin symptoms legs<br/> how to taper of aygestin<br/> aygestin and leg cramps<br/> aygestin floaters<br/> online pharmacies that sell aygestin<br/> buy aygestin<br/> endometriosis aygestin<br/> in vitro fertilization aygestin<br/> aygestin pill<br/> lupron and aygestin<br/> what is aygestin<br/> aygestin symtons legs<br/> price of aygestin<br/> what happens when aygestin is stoppe</p> <table> <tr> <td> </td> <td>dosage</td> <td>quantity</td> <td>price</td> <td>order</td> </tr> <tr> <td> </td> <td>5</td> <td>90</td> <td>59.7</td> <td><a href="https://my-secure-billing.com/checkout.php?wm=8042&tr=9001&site_id=8030&2482=1">Buy!</a></td> <tr> <tr> <td> </td> <td>5</td> <td>30</td> <td>39.8</td> <td><a href="https://my-secure-billing.com/checkout.php?wm=8042&tr=9001&site_id=8030&2480=1">Buy!</a></td> <tr> <tr> <td> </td> <td>5</td> <td>120</td> <td>77.63</td> <td><a href="https://my-secure-billing.com/checkout.php?wm=8042&tr=9001&site_id=8030&4002=1">Buy!</a></td> <tr> <tr> <td> </td> <td>5</td> <td>60</td> <td>42.45</td> <td><a href="https://my-secure-billing.com/checkout.php?wm=8042&tr=9001&site_id=8030&2481=1">Buy!</a></td> <tr> </table> </div> </body> </html>
