Replenishes the lack of folate, has a contraceptive and estrogen-progestational effect.
Monophasic low-dose combined oral estrogen-progestational contraceptive, which includes active and supplementary tablets with calcium levometholate.The contraceptive effect of Yarina Plus is carried out by suppressing ovulation and increasing the viscosity of the cervical mucus. In patients taking similar oral contraceptives, the cycle is normalized, the soreness, intensity and duration of bleeding decrease, and as a result, the risk of iron deficiency anemia decreases. There are also data on a decrease in the likelihood of the appearance of endometrial and ovarian neoplasms.Drospirenone demonstrates an antimineralocorticoid effect and prevents fluid retention, which can reduce body weight and reduce the risk of peripheral edema. It has antiandrogenic activity and helps to reduce acne, reduce fat and hair. These facts should be considered when choosing a contraceptive for women with a delay in fluid hormonal nature, as well as with acne.Levomefolat calcium is an active form of folate, digestible better than folic acid. It is necessary to meet the increased need for folate during pregnancy and during lactation. The presence of calcium levomefolate in a contraceptive oral means reduces the likelihood of a fetal neural tube in the event that a pregnancy occurs after the abolition of contraception.Pharmacokinetics
DrospirenoneAfter intake, it is absorbed quickly. The highest level in the blood is achieved after an hour and a half. Bioavailability is 76-85%. It binds to albumin and does not react with the hormone-binding globulin. Only 3-5% of the substance circulating in the blood is in free form. With the systematic use of the drug, the concentration of drospirenone in the blood increases 2-3 times. Most metabolites are acid derivatives of drospirenone. They are excreted through the kidneys and intestines.EthinylestradiolQuickly absorbed after ingestion. The maximum level in the blood is reached after an hour and a half. Food reduces bioavailability by 25%. Ethinyl estradiol reacts actively with blood albumin. It is transformed in the liver by aromatic hydroxylation with the production of numerous metabolites. It is excreted as metabolic products with urine and feces. The elimination half-life reaches 24 hours.Calcium levometholateQuickly absorbed after getting into the digestive tract. In the form of L-5-methyl-THF it is delivered to organs and peripheral tissues. Folates are involved in the biosynthesis of thymidine, purines, DNA, RNA, methionine and glycine. It is excreted mainly by the kidneys in the original form and in the form of metabolites.
Tablets are taken orally in the order indicated on the package, every day at the same time, washed down with water and not chewed.Yarina Plus, user's manual

The use of drugs that stimulate microsomal hepatic enzymes, can lead to an increase in the excretion of sex hormones. Such medicines include: barbiturates, phenytoin, primidone, carbamazepine, rifampicin and others.Some antibiotics (penicillins and tetracycline) are able to reduce the concentration of ethinyl estradiol.In the period of application of drugs acting on microsomal hepatic enzymes, and 4 more weeks after their withdrawal, the barrier method of contraception should be used additionally.During the application of antibiotics (Rifampicin and Griseofulvin do not cause such a need), and even within a week after their withdrawal, it is recommended to use the barrier method of contraception in addition.A number of drugs reduce the folate content in the blood or weaken the effectiveness of calcium levomefolate by blocking the enzyme dihydrofolate reductase (Trimethoprim, Methotrexate, Triamteren and Sulfasalazine), reducing folate absorption (Kolestyramin) or by unclear mechanisms (Phenobarbital, Carbamazepine, Primidone, Phenytoin, Valproic Acid).Folates are able to change the pharmacokinetic parameters of antiepileptic drugs, methotrexate, pyrimethamine, which is accompanied by a decrease in the therapeutic effect of the latter.Storage conditions
