Progesterone and the progestins have been used alone or in combination with estrogens in oral contraceptives, as therapy of postmenopausal symptoms, for secondary amenorrhea, abnormal uterine bleeding, endometriosis and progesterone sensitive cancers. High doses of progestins can cause liver test abnormalities and can occasionally lead to clinical apparent acute liver injury.</p></div><div id="Progestins.Background"><h3>Background</h3><p>Progesterone (proe jes' ter one) is the naturally occurring progestin which is secreted by the ovary and has a multitude of actions on many organs, but predominantly on the reproductive tract, mammary glands and central nervous system. Large amounts of progesterone are produced in women by the corpus luteum during the second half of the menstrual cycle, which inhibits the effects of estrogen on endometrial proliferation and results in a secretory status of the endometrium in preparation for implantation of a fertilized egg. If pregnancy does not occur, the corpus luteum regresses and levels of progesterone fall, triggering menstruation and resetting of the ovarian cycle. Progesterone also affects mammary glands and is required for their development and maintenance and, in the central nervous system, increases body temperature and ventilator responses. Progesterone also has androgenic and antiestrogenic effects and causes an increase in basal insulin levels, enhances fat deposition and decreases bone turnover. Modifications of the progesterone molecule can produce compounds with better absorption and pharmacokinetics and more focused and specific activities.</p><p>Progestins are compounds with biological activities similar to progesterone. Progestins developed for clinical use include desogestrel, dydrogesterone, levonorgestrel, medroxyprogesterone, megestrol, 19-nortestosterone, norethindrone, norgestrel and norgestimate, among others. Many of these progestins are used in combination with estrogens in oral contraceptives. In addition, some are used alone as contraceptive agents and to treat secondary amenorrhea, abnormal uterine bleeding, endometriosis, infertility and premature labor. Progestins have also been used to treat progesterone sensitive cancers (endometrial, renal, breast), and as therapy of anorexia and cachexia due to cancer chemotherapy or the acquired immunodeficiency syndrome (AIDS). Progestins used without estrogens include (with common brand names and year of approval in the United States): medroxyprogesterone (Provera and others: 1959), megestrol (Megase: 1971) and norethindrone (Camila, Errin, Micronor, Aygestin: 1973). Common side effects of progestin therapies include nausea, headaches, anxiety, weight gain, edema and breast tenderness and engorgement.</p></div><div id="Progestins.Hepatotoxicity"><h3>Hepatotoxicity</h3><p>High doses of progestins can cause liver enzyme elevations that generally rise after 1 to 2 weeks of treatment and consist largely of serum aminotransferase elevations without changes in alkaline phosphatase or bilirubin. These abnormalities are generally short lived and resolve rapidly with dose modification or discontinuation. These elevations may be more frequent when progestins are administered with high doses of estrogens or tamoxifen. Isolated case reports of symptoms with serum aminotransferase elevations and even jaundice during progestin therapy have been published, but the relationship to the hormonal therapy has not always been clear. In some instances, the liver injury was attributed to a progestin releasing intrauterine device (IUD). Finally, rare instances of cholestasis with bland hepatic injury that is typical of estrogen induced liver injury have been reported with use of progestins alone. The fact that progesterone derivatives can be metabolized to estrogenic compounds makes it possible that these cases of cholestatic jaundice are actually due to estrogens rather than the progestin molecules.</p><p><a class="def" href="/books/n/livertox/glossary/def-item/glossary.likelihood-score/">Likelihood score</a>: A (well established cause of clinically apparent liver injury).</p></div><div id="Progestins.Mechanism_of_Injury"><h3>Mechanism of Injury</h3><p>The mechanism by which progesterone therapy leads to liver injury is not known. Semi-synthetic progesterones may be metabolized to estrogenic compounds that might be responsible for the rare instances of cholestatic jaundice reported with progesterone only therapy.</p></div><div id="Progestins.Outcome_and_Management"><h3>Outcome and Management</h3><p>The rare instances of liver injury reported during progestin therapy have invariably been self-limiting and have resolved completely with stopping the progesterone preparation. Clearly documented fatal cases have not been published. Cross sensitivity to estrogen therapy has not been demonstrated in patients developing jaundice during progesterone therapy, but might be expected.</p><p>References to the safety and hepatic injury associated with progesterone and the progestins are given together after this introductory section. The safety and hepatic injury due to estrogenic agents and estrogen containing birth control pills are described in the overview section on Estrogens and Oral Contraceptives.</p><p>Drug Class: Obstetrical and Gynecological Agents; Hormonal Agents</p></div></div><div id="Progestins.PRODUCT_INFORMATION"><h2 id="_Progestins_PRODUCT_INFORMATION_">PRODUCT INFORMATION</h2><p>
