With its contraceptive effect, the combined Rosepire oral contraceptive may be the choice for birth control, menstrual cycle regulation, less menstrual bleeding and less pain.

Drospirenone has anti-mineralocorticoid effects that limit weight gain and other signs and symptoms caused by water retention. The active ingredient Drospirenone has the effect of neutralizing the sodium retention of estrogen, creating good tolerance and positive effects on premenstrual syndrome (PSM). When combined with Ethinylestradiol, Drospirenone acts as an appropriate lipid source to increase HDL. Drospirenone has an anti-androgen effect that reduces the growth of acne and sebum on the skin's surface. The active ingredient Drospirenone does not counteract the Ethinylestradiol-related increase in SHBG levels, providing an effect on the binding and inactivation of androgens in the body. Drospirenone has similar biochemical and pharmacological properties to the naturally occurring hormone progesterone. In addition, the combination of two active ingredients, Drospirenone and Ethinylestradiol, also reduces the risk of endometrial cancer, ovarian cancer, pelvic inflammatory disease, breast tumors and ectopic pregnancy.
1.2. Pharmacokinetics of the drug Drospirenone For the pharmaceutical substance Drospirenone
Absorption when using the drug Drospirenone orally, the drug is rapidly and almost completely absorbed. Peak serum concentrations of about 38 ng/ml are achieved 1 to 2 hours after a single oral dose. Bioavailability of the drug is about 76-85%. Concomitant administration of the drug with food does not affect the bioavailability of this drug. Distribution: Drospirenone is bound to serum albumin and not to sex hormone-binding globulin (SHBG) and corticoid liver globulin (CBG). The volume of distribution of active substance Drospirenone is 3.7 + 1.2 I/kg. Metabolism: Drospirenone is almost completely metabolised after oral administration. Drospirenone is minimally metabolised by CYP3A4. Elimination: Drospirenone is excreted in very small amounts as unchanged drug. The active metabolite Drospirenone is excreted in the feces and urine with an excretion ratio of 1.2 to 1.4. The half-life of metabolites in human urine and feces is approximately 40 hours. Steady state: During the treatment cycle, the maximum steady-state drug concentration of Drospirenone in serum is about 70 ng/ml, achieved about 7 days after taking the drug. For the pharmaceutical substance Ethinylestradiol
Absorption ability: When using the drug orally, the drug is rapidly and completely absorbed. After administration of the drug at a dose of 30ug, peak serum concentrations of 100pg/ml were achieved 1-2 hours after oral administration. Bioavailability of the active substance is about 45%. Taking the drug with food reduces the bioavailability of the drug. The volume of distribution is 5 L/kg. Metabolism: Ethinylestradiol is metabolised in both the small intestine and the liver. The active substance Ethinylestradiol is metabolized primarily through aromatic hydroxylation and a variety of hydroxylation and methylation metabolites are formed, which are either free or bound to sulfates and glucuronide radicals. Elimination: The drug is not excreted unchanged. The metabolites of the active substance Ethinylestradiol are excreted mainly in urine and bile in a ratio of 4:6. The average elimination time of metabolites is about 24 hours. The half-life of the chemical is about 20 hours on average.
