Description
Midiana Pharmacodynamics
A combined oral contraceptive drug containing ethinylestradiol and drospirenone. The contraceptive effect is based on the interaction of various factors, the most important of which are inhibition of ovulation and endometrial changes.
In a therapeutic dose drospirenone also has antiandrogenic and weak anti-mineralocorticoid properties. It has no estrogenic, glucocorticoid and antiglucocorticoid activity. This provides drospirenone with a pharmacological profile similar to that of natural progesterone.
There is evidence of a reduced risk of endometrial and ovarian cancer with combined oral contraceptives.
Indications
contraception.

If the vaginal ring or transdermal patch is replaced, the Midiana® oral contraceptive should preferably be started on the day of removal of the previous product; in such cases, the Midiana® should be started no later than the day of the intended replacement procedure.
- In case of progestin-only replacement method (mini-pills, injectable forms, implants) or intrauterine contraceptives with progestin release: a woman can switch from mini-pills on any day (from an implant or intrauterine contraceptive – on the day of its removal, from an injectable form – from the day when the next injection was to be made). However, in all these cases, it is advisable to use an additional barrier method of contraception during the first 7 days of taking the pills.

If administration is started later, barrier contraception should be used additionally during the first 7 days of taking the pills. If you have sexual intercourse before taking the drug, pregnancy must be excluded or you must wait for your first menstrual period.
- Taking missed pills
If the pill is taken less than 12 hours late, contraceptive protection is not reduced. The woman should take the pill as soon as possible, the next pills are taken at the usual time.
