[90][91][92] The loss of the C7α acetylthio group of spironolactone, a compound with negligible progestogenic activity,[93][94] appears to be involved in the restoration of progestogenic activity in drospirenone, as SC-5233, the analogue of spironolactone without a C7α substitution, has potent progestogenic activity similarly to drospirenone. [49] Systematic reviews and meta-analyses of all of the data in the mid-to-late 2010s found that birth control pills containing cyproterone acetate, desogestrel, drospirenone, or gestodene overall were associated with a risk of VTE of about 1.3- to 2.0-fold compared to that of levonorgestrel-containing birth control pills. [1][65][3][58] Drospirenone has no estrogenic activity and no appreciable glucocorticoid or antiglucocorticoid activity. [8] In contrast to ethinylestradiol-containing birth control pills, neither progestogen-only birth control nor the combination of transdermal estradiol and an oral progestin in menopausal hormone therapy is associated with an increased risk of VTE. [103] Bayer also reached a settlement for arterial thromboembolic events, including stroke and heart attacks, for US$56.9 million. [1][74][2] Drospirenone alone at 4 mg/day has been found to suppress estradiol levels in premenopausal women to about 40 to 80 pg/mL depending on the time of the cycle. The combined oral contraceptive pill (COC) consisting of drospirenone 3 mg/ethinyl estradiol 20 μg (3 mg DRSP/20 μg EE-24/4) supplies 24 days of pills with hormones followed by 4 days of hormone-free pills. [52][53][54][55] As a result, more androgenic progestins, like levonorgestrel and norethisterone, may oppose the procoagulatory effects of ethinylestradiol and result in a lower increase in risk of VTE. [41] In women with mild or moderate chronic kidney disease, or in combination with chronic daily use of other potassium-sparing medications (ACE inhibitors, angiotensin II receptor antagonists, potassium-sparing diuretics, heparin, antimineralocorticoids, or nonsteroidal anti-inflammatory drugs), a potassium level should be checked after two weeks of use to test for hyperkalemia. [4][2][5][6], Drospirenone is excreted in urine and feces, with slightly more excreted in feces than in urine. [7] Among others, it is marketed in combination with ethinylestradiol under the brand names Yasmin and Yaz and in combination with estradiol under the brand name Angeliq. [4] Treatment for 10 days with 200 mg twice daily ketoconazole, a strong CYP3A4 inhibitor among other actions, has been found to result in a moderate 2.0 to 2.7-fold increase in exposure to drospirenone. [7], Drospirenone is marketed widely throughout the world. [95], Drospirenone was patented in 1976 and introduced for medical use in 2000. [26][27], Studies have found that EE/DRSP is superior to placebo in reducing premenstrual emotional and physical symptoms while also improving quality of life. [13][14] It is available as a generic medication. [4][41][42] Renal impairment, hepatic impairment, and adrenal insufficiency are contraindicated because they increase exposure to drospirenone and/or increase the risk of hyperkalemia with drospirenone. If the pharmacy that's willing to deliver medicines to your home doesn't have drospirenone + ethinyl estradiol in stock, you can ask for one of the branded alternatives for drospirenone + ethinyl estradiol. [65] It has about 100 to 500% of the affinity of aldosterone for the MR and about 50 to 230% of the affinity of progesterone for the MR.[1][2][67][58] Drospirenone is about 5.5 to 11 times more potent as an antimineralocorticoid than spironolactone in animals. [28][29] E2/DRSP has been found to increase bone mineral density and to reduce the occurrence of bone fractures in postmenopausal women. 11 DESCRIPTION. [1][4] The two major metabolites of drospirenone are drospirenone acid and 4,5-dihydrodrospirenone 3-sulfate, and are both formed independently of the cytochrome P450 system. [103] This is in addition to around 10,000 claims that Bayer has already settled without admitting liability. [4] Elimination of drospirenone is virtually complete 10 days after the last dose. [4] There is no antidote for overdose of drospirenone and treatment of overdose should be based on symptoms. [4] Drospirenone does not appear to influence the metabolism of omeprazole (metabolized via CYP2C19), simvastatin (metabolized via CYP3A4), or midazolam (metabolized via CYP3A4), and likely does not influence the metabolism of other medications that are metabolized via these pathways. Global leader in steroidal APIs. [1][7] It is available both alone under the brand name Slynd and in combination with an estrogen under the brand name Yasmin among others. Product Presentation. Drospirenone is devoid of any estrogenic, glucocorticoid and antiglucocorticoid activity, which provides a pharmacological profile very close to the profile of the natural hormone progesterone. [1][2] It has about 1 to 65% of the affinity of the synthetic anabolic steroid metribolone for the AR. (2020). Drospirenone(Dihydrospirorenone) is a synthetic progestin that is an analog to spironolactone. Gianvi (drospirenone/ethinyl estradiol tablets) are available in packages of three blister packs (NDC 0093-5423-62). [50][51][45], Androgenic progestins have been found to antagonize to some degree the effects of ethinylestradiol on coagulation. [57][58] The combination of estradiol and drospirenone has been found to increase breast density, an established risk factor for breast cancer, in postmenopausal women. [42], Drospirenone has been found to stimulate the proliferation and migration of breast cancer cells in preclinical research, similarly to certain other progestins. [15] In 2017, a formulation of drospirenone with ethinylestradiol was the 98th most commonly prescribed medication in the United States, with more than eight million prescriptions. [1][65][3][58], Drospirenone is an agonist of the PR, the biological target of progestogens like progesterone. [7][88][98][99][100][101], Drospirenone is marketed in combination with an estrogen under a variety of brand names throughout the world. drospirenone was devoid of glucocorticoid activity. [4], Inhibitors and inducers of the cytochrome P450 enzyme CYP3A4 may influence the levels and efficacy of drospirenone. Some or all pharmacies who provide a home delivery service for medicines might insist on a prescription for drospirenone + ethinyl estradiol before they complete the sale. [2] Similar effects occur during the luteal phase of the menstrual cycle due to increased progesterone levels and the resulting antagonism of the MR.[2] Estrogens, particularly ethinylestradiol, activate liver production of angiotensinogen and increase levels of angiotensinogen and angiotensin II, thereby activating the renin–angiotensin–aldosterone system. In a therapeutic dose, drospirenone also has antiandrogenic and weak antimineralocorticoid activity. [1] Because of its antimineralocorticoid activity and lack of undesirable off-target activity, drospirenone is said to more closely resemble bioidentical progesterone than other progestins. [4][1] Drospirenone has no affinity for sex hormone-binding globulin (SHBG) or corticosteroid-binding globulin (CBG), and hence is not bound by these plasma proteins in the circulation. [4][8] Drospirenone is a progestin, or a synthetic progestogen, and hence is an agonist of the progesterone receptor, the biological target of progestogens like progesterone. Drospirenone is a spironolactone analogue with antimineralocorticoid activity. [103], Drospirenone is under development by Mithra Pharmaceuticals in combination with estetrol (tentative brand name Estelle) as a combined birth control pill for prevention of pregnancy in women. USDMF . Preclinical studies in animals and . primary mechanism of this action is inhibition of ovulation, other alterations include changes in . Application Number. It would be best to get this clarified while placing the order. Drospirenone is a progestin medication which is used in birth control pills to prevent pregnancy and in menopausal hormone therapy, among other uses. Drospirenone has another hormonal mechanism: that of an antiandrogeni c hormone, which exerts its progestatio nal and ant imine raloc ortic oid ef fects b y compe titiv ely in hibit ing Pharmacology For Drospirenone + Ethinyl estradiol, directory of Pharmacies, Chemists and Druggists, branded alternatives for drospirenone + ethinyl estradiol, Ministry of Health & Family Welfare-Government of India, Department of Health Research (DHR), Government of India, Department of Indian Systems of Medicine and Homoeopathy, Pharmacopoeial Laboratory for Indian Medicine (PLIM). 3. [104] As of October 2019, it is in phase III clinical trials. [2][1] As a result, they can produce undesirable side effects including increased sodium excretion, water retention, weight gain, and increased blood pressure. [104], A combination of ethinylestradiol, drospirenone, and prasterone is under development by Pantarhei Bioscience as a combined birth control pill for prevention of pregnancy in women. 13.1 Carcinogenesis, Mutagenesis, Impairment of Fertility . Drospirenone (6R,7R,8R,9S,10R,13S,14S,15S,16S,17S)-1,3’,4’,6,6a,7,8,9,10,11, 12,13,14,15,15a,16-hexadecahydro-10,13-dimethylspiro-[17H-dicyclopropa- [6,7:15,16]cyclopenta[a]phenanthrene-17,2’(5H)-furan]-3,5’(2H)-dione) is a synthetic progestational compound and has a molecular weight of 366.5 and a molecular formula of C24H30O3. [16][17], Drospirenone (DRSP) is used by itself as a progestogen-only birth control pill, in combination with the estrogen ethinylestradiol (EE), with or without supplemental folic acid (vitamin B9), as a combined birth control pill, and in combination with the estrogen estradiol (E2) for use in menopausal hormone therapy. [82][83], Drospirenone is an antagonist of the AR, the biological target of androgens like testosterone and dihydrotestosterone (DHT). Ethinyl … [19][20] For use in menopausal hormone therapy, E2/DRSP is specifically approved to treat moderate to severe vasomotor symptoms (hot flashes), vaginal atrophy, and postmenopausal osteoporosis. Mechanism of Action Estrogen receptor agonists; Mineralocorticoid receptor antagonists; Progesterone receptor agonists; Testosterone congener inhibitors Orphan Drug Status Orphan designation is assigned by a regulatory body to encourage companies to develop drugs for rare diseases. [105], Drospirenone has been suggested for potential use as a progestin in male hormonal contraception. [33], Drospirenone is available in the following formulations, brand names, and indications:[34][35], Contraindications of drospirenone include renal impairment or chronic kidney disease, adrenal insufficiency, presence or history of cervical cancer or other progestogen-sensitive cancers, benign or malignant liver tumors or hepatic impairment, undiagnosed abnormal uterine bleeding, and hyperkalemia (high potassium levels). 13 NONCLINICAL TOXICOLOGY . [8][56], In the early 2010s, the FDA updated the label for birth control pills containing drospirenone and other progestins to include warnings for stopping use prior to and after surgery, and to warn that such birth control pills may have a higher risk of blood clots. [1][2][3][58] The medication is more potent as an antiandrogen than spironolactone, but is less potent than cyproterone acetate, with about 30% of its antiandrogenic activity in animals. Call your doctor or seek emergency medical help if you have severe pain in your lower stomach or side. Instruct women to report adverse events to their prescribers. You are even more at risk if you have high blood pressure, diabetes, high cholesterol, or if you are overweight.Your risk of stroke or blood clot is highest during your first year of taking birth control pills. [45][46] The risk of VTE during pregnancy is 5 to 20 in 10,000 women per year and during the postpartum period is 40 to 65 per 10,000 women per year. [4], The distribution half-life of drospirenone is about 1.6 to 2 hours. 21733. [71] The total endometrial transformation dose of drospirenone is about 50 mg per cycle, whereas its daily dose is 2 mg for partial transformation and 4 to 6 mg for full transformation. [68][69][1][70] Inhibition of ovulation occurred in about 90% of women at a dose of 0.5 to 2 mg/day and in 100% of women at a dose of 3 mg/day. YASMINELLE ® is an oral contraceptive consisting of an estrogenic hormone such as ethinyl estradiol and a progestogen such as drospirenone. [31][32] Due to its antimineralocorticoid activity, drospirenone opposes estrogen-induced salt and water retention and maintains or slightly reduces body weight. [1][4] The medication is also metabolized by reduction of its double bond between the C4 and C5 positions and subsequent sulfation. [8][47], Different progestins in ethinylestradiol-containing birth control pills have been associated with different risks of VTE. [1][2][58] Drospirenone has antigonadotropic and functional antiestrogenic effects as a result of PR activation. [44] The incidence is about 4-fold higher on average than in women not taking a birth control pill. The egg can no longer accept a … [2] The medication does not inhibit the effects of ethinylestradiol on sex hormone-binding globulin (SHBG) and serum lipids, in contrast to androgenic progestins like levonorgestrel but similarly to other antiandrogenic progestins like cyproterone acetate. [105] It includes prasterone (dehydroepiandrosterone; DHEA), an oral androgen prohormone, to replace testosterone and avoid testosterone deficiency caused by suppression of testosterone by ethinylestradiol and drospirenone.

[103] These claims of VTE have amounted to US$1.97 billion. It is an agonist of the PR and an antagonist of the MR and AR, and hence is a progestogen, antimineralocorticoid, and antiandrogen. Drospirenone counteracts the estrogen-induced stimulation of the renin-angiotensin-aldosterone system and blocks testosterone from binding to … Virtual Booth. [13][14] The medication was approved for use in menopausal hormone therapy in combination with estradiol in 2005. [4][1] It is bound to albumin and 3 to 5% circulates freely or unbound. [11] Drospirenone is sometimes described as a "fourth-generation" progestin based on its time of introduction. [105] As of August 2018, the formulation is in phase II/III clinical trials. Contact Supplier. [75][76][77] In male cynomolgus monkeys however, 4 mg/kg/day oral drospirenone strongly suppressed testosterone levels. [4][2] Neither of these metabolites are known to be pharmacologically active. Some of the brands for drospirenone + ethinyl estradiol might be better known than drospirenone + ethinyl estradiol itself. Mechanism of Action 12.2 . Ethinyl estradiol: Reduces LHRH release from hypothalamus, reduces gonadotropin release from pituitary; increases synthesis of DNA, RNA, and various proteins in target tissues; other possible mechanisms include changes in cervical mucus that cause inhibition of sperm penetration and endometrial changes that reduce likelihood of implantation . Det er gratis at tilmelde sig og byde på jobs. 14 CLINICAL STUDIES . [7], Drospirenone has been categorized as a "fourth-generation" progestin. 2018-03-26. [62] Progestogen-only birth control is not generally associated with a higher risk of breast cancer. Italy. [1], Common side effects include acne, headache, breast tenderness, weight increase, and menstrual changes. [4], Adverse effects of drospirenone alone occurring in more than 1% of women may include unscheduled menstrual bleeding (breakthrough or intracyclic) (40.3–64.4%), acne (3.8%), metrorrhagia (2.8%), headache (2.7%), breast pain (2.2%), weight gain (1.9%), dysmenorrhea (1.9%), nausea (1.8%), vaginal hemorrhage (1.7%), decreased libido (1.3%), breast tenderness (1.2%), and irregular menstruation (1.2%). [86] Androgenic progestins like levonorgestrel have been found to inhibit the procoagulatory effects of estrogens like ethinylestradiol on hepatic synthesis of coagulation factors, whereas this may occur less or not at all with weakly androgenic progestins like desogestrel and antiandrogenic progestins like drospirenone. Mechanism of Action of Drospirenone Drospirenone diffuse freely into target cells in the female reproductive tract, mammary gland, hypothalamus, and the pituitary and bind to the progesterone receptor. [63][62][64], These have been no reports of serious adverse effects with overdose of drospirenone. [18] A birth control pill with low-dose ethinylestradiol is also indicated for the treatment of moderate acne, premenstrual syndrome (PMS), premenstrual dysphoric disorder (PMDD), and dysmenorrhea (painful menstruation). [1][65] It has about 35% of the affinity of promegestone for the PR and about 19 to 70% of the affinity of progesterone for the PR. [75], Drospirenone has been studied in forms for parenteral administration. The film-coated tablets are rounded with biconvex faces, one side is embossed with DS or DP in a regular hexagon. [1] For comparison to progesterone, a 200 mg dose of oral progesterone is considered to be approximately equivalent in antimineralocorticoid effect to a 25 to 50 mg dose of spironolactone. [8] Birth control pills containing progestins such as desogestrel, gestodene, drospirenone, and cyproterone acetate have been found to have 2- to 3-fold the risk of VTE of birth control pills containing levonorgestrel in retrospective cohort and nested case–control observational studies. [79][4] It has been said that the pharmacological profile of drospirenone more closely resembles that of progesterone than other progestins due to its antimineralocorticoid activity. [2] Drospirenone and its metabolites are excreted in urine about 38% as glucuronide conjugates, 47% as sulfate conjugates, and less than 10% in unconjugated form. Action . SLYND (drospirenone) is for use as an oral contraceptive. [59][60][61], Data on risk of breast cancer in women with newer progestins like drospirenone are lacking at present. The European Journal of Contraception & Reproductive Health Care. 14.1 . [1][4][2] Peak levels of drospirenone at steady state with 4 mg/day drospirenone are about 41 ng/mL. [80] Both drospirenone and progesterone are actually weak partial agonists of the MR in the absence of mineralocorticoids. [58], Many lawsuits have been filed against Bayer, the manufacturer of drospirenone, due to the higher risk of venous thromboembolism (VTE) that has been observed with combined birth control pills containing drospirenone and certain other progestins relative to the risk with levonorgestrel-containing combined birth control pills. [25] Drospirenone has also been used in combination with an estrogen as a component of hormone therapy for transgender women. [1], The metabolism of drospirenone is extensive. Folate Supplementation Clinical Trials . [89], Spirolactones like drospirenone and spironolactone are derivatives of progesterone, which likewise has progestogenic and antimineralocorticoid activity. Update your events Sterling Spa. [1][72][71] The medication acts as a contraceptive by activating the PR, which suppresses the secretion of luteinizing hormone, inhibits ovulation, and alters the cervical membrane and endometrium. [57][58] However, some evidence suggests that drospirenone may do this more weakly than certain other progestins, like medroxyprogesterone acetate. Please be aware that you should take drospirenone + ethinyl estradiol only if a doctor has recommended or prescribed it. [8][56][52][53][54][55], Drospirenone stimulates the proliferation of MCF-7 breast cancer cells in vitro, an action that is independent of the classical PRs and is instead mediated via the progesterone receptor membrane component-1 (PGRMC1). [8][45] However, this area of research is controversial, and confounding factors may have been present in these studies. [65], Drospirenone is an antagonist of the MR, the biological target of mineralocorticoids like aldosterone, and hence is an antimineralocorticoid. 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. [2] Progesterone and drospirenone counteract these undesirable effects via their antimineralocorticoid activity. Mechanism of Action. [85][1][3], Drospirenone shows antiandrogenic effects on the serum lipid profile, including higher HDL cholesterol and triglyceride levels and lower LDL cholesterol levels, at a dose of 3 mg/day in women. As far as the mechanism of action is concerned, the literature has been sustaining the direct role of COCs in hsCRP determination by affecting the latter’s metabolic and genetic regulation . [2], The elimination half-life of drospirenone is between 25 and 33 hours. Medicine India is just a publishing medium for medicine related information and does not provide services or sales of medicines including drospirenone + ethinyl estradiol. [7] Its name is a shortened form of the name 1,2-dihydrospirorenone or dihydrospirenone. Oral Contraceptive Clinical Trial 14.2 . Home delivery services for drospirenone + ethinyl estradiol may be free or they may cost you depending on the pharmacy and the minimum order requirements. [1][65][66][3] It is an agonist of the PR and an antagonist of the MR and AR, and hence is a progestogen, antimineralocorticoid, and antiandrogen. [4] At least 20 different metabolites can be identified in urine and feces. Søg efter jobs der relaterer sig til Drospirenone mechanism of action, eller ansæt på verdens største freelance-markedsplads med 18m+ jobs. Therefore, serum potassium and sodium, and evidence of metabolic acidosis, should be monitored in cases of overdose. [1][65] The ovulation-inhibiting dosage of drospirenone is 2 to 3 mg/day. CPhI China 2020. Mechanism of Action of Drospirenone Drospirenone diffuse freely into target cells in the female reproductive tract, mammary gland, hypothalamus, and the … [3][2][58], Due to its antimineralocorticoid activity, drospirenone increases natriuresis, decreases water retention and blood pressure, and produces compensatory increases in plasma renin activity as well as circulating levels and urinary excretion of aldosterone. [7] The medication is sometimes referred to as a "fourth-generation" progestin. [73][4], Due to its antigonadotropic effects, drospirenone inhibits the secretion of the gonadotropins, luteinizing hormone (LH) and follicle-stimulating hormone (FSH), and suppresses gonadal sex hormone production, including of estradiol, progesterone, and testosterone.
