The oral LD50 of drospirenone in rats is >2000 mg/kg. Overdose information An overdose of drospirenone, like other oral contraceptives, may lead to cause nausea or withdrawal bleeding. For drospirenone in particular, as an analog of spironolactone, may affect the levels of serum sodium and potassium. Their concentrations should be monitored in cases of overdose in addition to monitoring from metabolic acidosis and hyperkalemia, which may also result.

/AQUATIC SPECIES/ ...The effects of two progestins currently marketed in contraceptive formulations, levonorgestrel (LNG) and drospirenone (DRSP), were investigated in adult fathead minnows (Pimephales promelas) following an OECD 21-day fish reproduction screening assay draft protocol with additional end points. Levonorgestrel was tested at measured concentrations of 0.8, 3.3, and 29.6 ng/L, and DRSP at concentrations of 0.66, 6.5, and 70 uL. Both tested progestins caused an inhibition of reproduction. For LNG, this occurred at concentrations of 2:0.8 ng/L, no no-observed-effect concentration (NOEC) could be defined. Higher concentrations resulted in masculinization of females with de novo synthesis of nuptial tubercles. Drospirenone treatment, however, affected the reproductive success of fathead minnow at concentrations of 6.5 uL and higher with a clear dose-response relationship and a NOEC of 0.66 uL, which is above environmentally relevant concentrations.

Gianvi is contraindicated in patients with hepatic dysfunction. The mean exposure to DRSP in women with moderate liver impairment is approximately three times higher than the exposure in women with normal liver function. Gianvi has not been studied in women with severe hepatic impairment.|Gianvi is contraindicated in patients with renal insufficiency. The effect of renal insufficiency on the pharmacokinetics of DRSP (3 mg daily for 14 days) and the effect of DRSP on serum potassium levels were investigated in female subjects (n = 28, age 30-65) with normal renal function and mild and moderate renal impairment. All subjects were on a low potassium diet. During the study 7 subjects continued the use of potassium sparing drugs for the treatment of the underlying illness. On the 14th day (steady-state) of DRSP treatment, serum DRSP levels in the group with mild renal impairment (creatinine clearance CLcr, 50-80 mL/min) were comparable to those in the group with normal renal function (CLcr, >80 mL/min). The serum DRSP levels were on average 37 % higher in the group with moderate renal impairment (CLcr, 30-50 mL/min) compared to those in the group with normal renal function. DRSP treatment was well tolerated by all groups. DRSP treatment did not show any clinically significant effect on serum potassium concentration.|Mental depression may occur in women receiving oral contraceptives. In a few cases, mental depression has been severe and has led to suicidal behavior. Mental depression appears to occur most frequently in patients with a history of depression, including premenstrual depression; however, relief of premenstrual tension occurs in some women. Patients with a history of mental depression should be observed carefully and the estrogen-progestin contraceptive discontinued if severe depression recurs during use. /Estrogen-Progestin Combination/|Oral contraceptives have been reported to produce harmful ocular effects in myopic women. In women who developed myopia at or near puberty and in whom myopia became stable in adulthood, the drugs have reportedly increased the refractive error 2- to 3-fold, usually after 6 months of use. In women who are myopic and have considerable astigmatism, oral contraceptives may produce marked changes in the astigmatic error, possibly leading to frank keratoconus. In addition, oral contraceptives may produce a rapid advancement of the ocular disorder in patients with a family history of marked myopic astigmatism or keratoconus. Contact lens wearers receiving estrogen-progestin contraceptives may have more difficulties with their contact lenses than do nonusers who wear contact lenses. Contact lens wearers who develop visual disturbances or changes in lens tolerance during estrogen-progestin contraceptive use should be assessed by an ophthalmologist; temporary or permanent cessation of contact lens wear should be considered. /Estrogen-Progestin Combination/

Drospirenone is about 95% to 97% bound to serum plasma protein, likely to albumin. During in vitro studies, drospirenone was found to bind with low affinity to sex hormone-binding globulin (SHBG). Another reference indicates that drospirenone binds to serum albumin but does not bind to sex hormone-binding globulin (SHBG), nor corticoid binding globulin (CBG). Only 3-5% of the total drospirenone concentration is measured as a free steroid.

Drospirenone, in combination with ethinyl estradiol, is indicated as an oral contraceptive for the prevention of pregnancy. In addition to its use for contraceptive effects, this combination is used to treat moderate acne vulgaris and the symptoms of premenstrual dysphoric disorder. The drug has approved indications for combination with estrogens for the treatment of menopause-associated symptoms, such as vasomotor symptoms and vulvovaginal atrophy. Drospirenone combined with estrogen may also may aid in the prevention of osteoporosis in women who have been post-menopausal for at least a year and are not candidates for other therapies. It can sometimes be found in preparations containing estrogen and folic acid for folic acid replenishment during oral contraception. When used for the treatment of acne vulgaris, drospirenone-containing contraceptives should only be used in women ≥14 years of age who have experienced menarche, desire oral contraception, and do not have any contraindications to oral contraceptives. Off-label uses for this drug include the treatment of menstrual irregularities, dysmenorrhea, hirsutism, and endometriosis.|FDA Label|Prevention of pregnancy|Contraception, Inappropriate diet and eating habits|Contraception, Treatment of acne|oral contraceptive|Oral contraception.The decision to prescribe Lydisilka should take into consideration the individual woman's current risk factors, particularly those for venous thromboembolism (VTE), and how the risk of VTE with Lydisilka compares with other combined hormonal contraceptives (CHCs) (see sections 4.3 and 4.4).

/BOXED WARNING/ WARNING: CIGARETTE SMOKING AND SERIOUS CARDIOVASCULAR EVENTS. Cigarette smoking increases the risk of serious cardiovascular events from combination oral contraceptives (COC) use. This risk increases with age, particularly in women over 35 years of age, and with the number of cigarettes smoked. For this reason, COCs should not be used by women who are over 35 years of age and smoke|Cigarette smoking increases the risk of serious cardiovascular side effects from oral contraceptive use. This risk increases with age and with heavy smoking (15 or more cigarettes per day) and is quite marked in women over 35 years of age. Women who use oral contraceptives should be strongly advised not to smoke.|Gianvi contains ... the progestin drospirenone that has antimineralocorticoid activity, including the potential for hyperkalemia in high-risk patients, comparable to a ... dose of spironolactone. Gianvi should not be used in patients with conditions that predispose to hyperkalemia (ie renal insufficiency, hepatic dysfunction and adrenal insufficiency). Women receiving daily, long-term treatment for chronic conditions or diseases with medications that may increase serum potassium should have their serum potassium level checked during the first treatment cycle. Medications that may increase serum potassium include ACE inhibitors, angiotensin - II receptor antagonists, potassium-sparing diuretics, potassium supplementation, heparin, aldosterone antagonists, and NSAIDS.|Use of oral contraceptives is associated with an increased risk of several serious conditions including thromboembolism, stroke, myocardial infarction, liver tumor, gallbladder disease, visual disturbances, fetal abnormalities, and hypertension. Cigarette smoking increases the risk of serious adverse cardiovascular effects during oral contraceptive use. This risk increases with age and with heavy smoking (15 or more cigarettes daily) and is markedly greater in women older than 35 years of age. Women who are receiving estrogen-progestin contraceptives should be strongly advised not to smoke. Women older than 35 years of age who smoke, and women with ischemic heart disease or a history of this disease, should not use estrogen-progestin contraceptives. Estrogen-progestin contraceptives should be used with caution in women with cardiovascular disease risk factors. /Estrogen-Progestin Combination/|For more Drug Warnings (Complete) data for Drospirenone (39 total), please visit the HSDB record page.

Drospirenone inhibits the maturation of follicles and inhibits ovulation, preventing pregnancy. It has antiandrogen effects, improving acne and hirsutism. When combined with ethinyl estradiol, it has been shown to have favorable effects on the plasma lipid profile. Due to its similarity to naturally occurring progesterone, drospirenone is thought to be associated with a lower incidence of progesterone contraceptive related adverse effects, such as breast tenderness and mood swings. **A note on venous thromboembolism risk and antimineralcorticoid effects** As with other oral contraceptives, the risk of venous thromboembolism and cardiovascular events may be increased when drospirenone is taken. The risk is especially higher in smokers and women aged 35 and older. Women taking this drug should be advised not to smoke. In addition, drospirenone, due to its antimineralcorticoid effects, may increase the risk of hyperkalemia. Patients at high risk for hyperkalemia should not be administered this drug. Consult the official prescribing information for detailed and updated information on the cardiovascular and other risks associated with drospirenone use.

The absolute bioavailability of drospirenone is approximately 76% due to first-pass effects. The maximum plasma concentration of drospirenone occurs within 1 to 2 hours after oral administration and is estimated to range between 60 and 87 ng/mL. A European prescribing monograph for the combination product of estradiol and drospirenone indicates that drospirenone is both completely and rapidly absorbed. It reports a Cmax of 21.9 ng/ml, achieved approximately 1-hour post-administration. The absolute bioavailability is reported to range between 76 to 85%.|Various metabolites of drospirenone are measured in the urine and feces. Drospirenone elimination from the body is almost after 10 days post-administration when negligible amounts of drospirenone are found unchanged in both the urine and feces. Between 38% to 47% of the metabolites are identified as glucuronide and sulfate conjugates in the urine. In the feces, approximately 17% to 20% of identifiable metabolites are found to be excreted as glucuronides and sulfates.|The volume of distribution of drospirenone is estimated to be 4 L/kg, according to the FDA label for Yaz. Prescribing information from a combination of estradiol and drospirenone estimates the volume of distribution to range from 3.7- 4.2 L/kg.|Drospirenone is rapidly cleared, typically within 2-3 days of administration of the last active tablet. The rate of clearance of drospirenone calculated in the serum ranges from 1.2-1.5 ml/min/kg, however, this value can vary by up to 25% according to the patient.|The absolute bioavailability of drospirenone (DRSP) from a single entity tablet is about 76%. Serum concentrations of DRSP and EE reached peak levels within 1-2 hours after administration of Gianvi.|The pharmacokinetics of DRSP are dose proportional following single doses ranging from 1-10 mg. Following daily dosing of Gianvi, steady state DRSP concentrations were observed after 8 days. There was about 2 to 3 fold accumulation in serum Cmax and AUC (0-24hr) values of DRSP following multiple dose administration of Gianvi.|The rate of absorption of DRSP and EE following single administration of a formulation similar to Gianvi was slower under fed (high fat meal) conditions with the serum Cmax being reduced about 40% for both components. The extent of absorption of DRSP, however, remained unchanged.|DRSP and EE serum levels decline in two phases. The apparent volume of distribution of DRSP is approximately 4 L/kg and that of EE is reported to be approximately 4-5 L/kg.|For more Absorption, Distribution and Excretion (Complete) data for Drospirenone (10 total), please visit the HSDB record page.

Drospirenone is heavily metabolized. The two major inactive metabolites identified are the acid form of drospirenone produced by the opening of its lactone ring, known as M11, and the 4,5-dihydro-drospirenone-3-sulfate (M14). Drospirenone also undergoes oxidative metabolism via the hepatic cytochrome enzyme CYP3A4.|The two main metabolites of DRSP found in human plasma were identified to be the acid form of DRSP generated by opening of the lactone ring and the 4,5-dihydrodrospirenone-3-sulfate. These metabolites were shown not to be pharmacologically active. In in vitro studies with human liver microsomes, DRSP was metabolized only to a minor extent mainly by Cytochrome P450 3A4 (CYP3A4).

The serum half-life of drospirenone is estimated to be 30 hours. The half-life of drospirenone metabolite excretion in the urine and feces is approximately 40 hours.|DRSP serum levels are characterized by a terminal disposition phase half-life of approximately 30 hours after both single and multiple dose regimens.

Drospirenone and ethinyl estradiol in combination suppress the release of follicle stimulating hormone (FSH) and luteinizing hormone (LH), preventing ovulation. Other changes induced by this drug which may aid in the prevention of pregnancy include alterations in cervical mucus consistency, hindering sperm movement, and lowering the chance of embryo implantation. Drospirenone is an analog of the diuretic spironolactone, which exerts anti-mineralocorticoid activity, blocking aldosterone receptors, which increases sodium and water excretion. Studies in animals have demonstrated that drospirenone administration leads to antiandrogenic activity. This activity helps to oppose the effects of naturally occurring androgens, inhibiting the binding of dihydrotestosterone (DHT) to its receptor, and preventing androgen synthesis in the ovaries, helping to treat acne and hirsutism. Drospirenone may also decrease the level of edema in sebaceous follicle during the second half of the menstrual cycle, when acne often appears.|Combination oral contraceptives (COCs) act by suppression of gonadotropins. Although the primary mechanism of this action is inhibition of ovulation, other alterations include changes in the cervical mucus (which increases the difficulty of sperm entry into the uterus) and the endometrium (which reduces the likelihood of implantation).|Drospirenone is a spironolactone analogue with antimineralocorticoid activity. Preclinical studies in animals and in vitro have shown that drospirenone has no androgenic, estrogenic, glucocorticoid, or antiglucocorticoid activity. Preclinical studies in animals have also shown that drospirenone has antiandrogenic activity.|Acne vulgaris is a skin condition with a multifactorial etiology including androgen stimulation of sebum production. While the combination of ethinyl estradiol and drospirenone increases sex hormone binding globulin (SHBG) and decreases free testosterone, the relationship between these changes and a decrease in the severity of facial acne in otherwise healthy women with this skin condition has not been established. The impact of the antiandrogenic activity of drospirenone on acne is not known.|.... The pharmacological properties of drospirenone were investigated in vitro by receptor binding and transactivation experiments and in vivo in appropriate animal models. In qualitative agreement with progesterone, the compound binds strongly to the progesterone and the mineralocorticoid receptor and with lower affinity to androgen and glucocorticoid receptors. There is no detectable binding to the estrogen receptor. Steroid hormone agonistic and antagonistic activities of progesterone and drospirenone were compared in transactivation experiments. Individual steroid hormone receptors were artificially expressed together with a reporter gene in appropriate cell lines. Both hormones were unable to induce any androgen receptor-mediated agonistic activity. Rather, both progesterone and drospirenone distinctly antagonized androgen-stimulated transcriptional activation. Likewise, both compounds only very weakly activated the mineralocorticoid receptor but showed potent aldosterone antagonistic activity. Drospirenone did not induce glucocorticoid receptor-driven transactivation. Progesterone was a weak agonist in this respect. Drospirenone exerts potent progestogenic and antigonadotropic activity which was studied in various animal species. It efficiently promotes the maintenance of pregnancy in ovariectomized rats, inhibits ovulation in rats and mice and stimulates endometrial transformation in the rabbit. Furthermore, drospirenone shows potent antigonadotropic, i.e., testosterone-lowering activity in male cynomolgus monkeys. The progestogenic potency of drospirenone was found to be in the range of that of norethisterone acetate. The majority of clinically used progestogens are androgenic. Drospirenone, like progesterone, has no androgenic but rather an antiandrogenic effect. This property was demonstrated in castrated, testosterone propionate substituted male rats by a dose-dependent inhibition of accessory sex organ growth (seminal vesicles, prostate). In this model, the potency of drospirenone was about a third that of cyproterone acetate. Drospirenone, like progesterone, shows antimineralocorticoid activity, which causes moderately increased sodium and water excretion. This is an outstanding characteristic which has not been described for any other synthetic progestogen before. Drospirenone is eight to ten times more effective in this respect than spironolactone. The natriuretic effect was demonstrable for at least three weeks upon daily treatment of rats with a dose of 10 mg/animal. Drospirenone is devoid of any estrogenic, glucocorticoid or antiglucocorticoid activity. In summary, drospirenone, like progesterone, combines potent progestogenic with antimineralocorticoid and antiandrogenic activity in a similar dose range.|For more Mechanism of Action (Complete) data for Drospirenone (9 total), please visit the HSDB record page.

/HUMAN EXPOSURE STUDIES/ ... Forty postmenopausal women ... were randomly submitted to receive treatment with an oral dose of E2 (1 mg) plus drospirenone (2 mg) (group A) or placebo (group B). Hormonal and lipid assessment; evaluation of glucose and insulin metabolism by the clamp test and the oral glucose tolerance test; evaluation of endothelial function by the vascular reactivity test. Total cholesterol levels, low-density lipoprotein cholesterol levels, and nonesterified fatty acids levels significantly decreased both after 3 and 6 months. No changes in high-density lipoprotein, triglycerides, apolipoprotein A1, apolipoprotein B, and lipoprotein (a) were found. Treatment resulted in few changes in glycoinsulinemic metabolism. /Investigators/ observed a significant reduction of the area under curve of insulin after 6 months of therapy. Endothelial function was significantly influenced by treatment, and an improvement in both flow-mediated dilatation and nitrate-mediated dilatation values after 6 months was observed. Low-dose E2/drospirenone treatment did not reveal any negative effect on carbohydrate metabolism, acting in a neutral way on insulin sensitivity. The treatment induced favorable changes in lipid profile and showed a significant improvement of vascular reactivity.|/HUMAN EXPOSURE STUDIES/ To investigate ovulation inhibition with drospirenone, a novel progestogen that has a profile similar to natural progesterone, when given alone or in combination with ethinylestradiol. Hormonal parameters (LH, FSH, 17beta-estradiol and progesterone) and peripheral parameters (cervical score, spinnbarkeit and crystallization), as well as follicle size assessed by ultrasonography, were measured in two groups of healthy women. Forty-eight women aged 19-35 years were randomly assigned to receive 0.5 mg, 1.0 mg, 2.0 mg or 3.0 mg of drospirenone over a single treatment cycle, and 52 women aged 20-35 years were randomized to receive either 2 mg drospirenone/30 ug ethinylestradiol or 3 mg drospirenone/30 ug ethinylestradiol over three treatment cycles. Baseline measurements were taken during a control pretreatment cycle. Adequate ovarian suppression with drospirenone alone was evident at dose levels of 2 and 3 mg, and at 3 mg all subjects had anovulatory cycles. Although both combined preparations (2 mg and 3 mg drospirenone/30 ug ethinylestradiol) inhibited the hypothalamic-pituitary-ovarian axis, follicular maturation leading to escape ovulation was observed in three subjects in the 2 mg drospirenone/30 ug ethinylestradiol group. Only one of these ovulations was considered to be definitely the result of treatment failure. All cycles in the 3 mg drospirenone/30 ug ethinylestradiol group were anovulatory. No statistically significant difference was found between treatment groups. ...|/HUMAN EXPOSURE STUDIES/ /The authors/ investigated the effect of a combination of ethinyl estradiol (EE) plus a progestogen with antimineralocorticoid, i.e. natriuretic, properties [Drospirenone (DRSP)] on body weight, blood pressure, the renin-aldosterone system, atrial natriuretic factor, plasma lipids, and glucose tolerance. It is anticipated that this will lead to the development of an OC that does not raise body weight or blood pressure. Four groups of 20 women each received 30 ug EE plus 3 mg DRSP (group A), 20 ug EE plus 3 mg DRSP (group B), 15 ug EE plus 3 mg DRSP (group C), and, as a control OC, 30 ug EE plus 150 ug levonorgestrel (Microgynon, Schering; group D) for 6 months. During the OC-free control cycles before and after treatment and throughout treatment, the target parameters were measured. Between the pretreatment cycle and the sixth treatment cycle, mean body weight fell by 0.8 to 1.7 kg in groups A, B, and C (P < 0.05 vs. D), whereas it rose by 0.7 kg in group D. Systolic and diastolic blood pressures fell by 1-4 mm Hg in groups A, B, and C (significant for A and C vs. D) and increased by 1-2 mm Hg in group D. Renin substrate rose equally in all groups (P < 0.05), whereas PRA and plasma aldosterone rose significantly only in the DRSP groups, presumably due to sodium loss. In the DRSP groups, high density lipoprotein cholesterol rose (P < 0.05), in contrast to group D. Low density lipoprotein cholesterol fell slightly (P > 0.05), whereas triglyceride levels showed a stronger increase in the DRSP groups (P < 0.05) than in group D. All groups attained good cycle control; group A had the best. Side-effects were minimal. ...|/SIGNS AND SYMPTOMS/ Serious ill effects have not been reported following acute ingestion of large doses of other oral contraceptives by young children.
