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/

Drospirenone, in combination with ethinyl estradiol or estetrol, 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
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.

Absorption
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%.
Route of Elimination
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.
Volume of Distribution
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.
Clearance
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.

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.
