Junel fe contraceptive pill ,This combination hormone medication is used for the prevention of pregnancy. It contains two hormones: norethindrone, a progestin, and ethinyl estrogen. It prevents the release of eggs (ovulation) during menstrual cycles. It makes the vaginal fluid thicker, which helps prevent sperm from reaching the egg (fertilization), and alters the lining of your uterus (womb), to prevent fertilized eggs from attaching to it. A fertilized egg that does not attach to its uterus will be removed from the body. Each of the 7 inactive pills taken in the fourth week contains a small amount iron (ferrous fumarate). Inactive tablets do not contain hormones. The inactive pills do not contain hormones.Junel fe contraceptive pill

Combination oral contraceptives suppress gonadotropins. While the main mechanism is the inhibition of ovulation (which is the primary reason for this action), there are other factors that can affect the effectiveness of the combination oral contraceptives. These include changes in cervical mucus, which makes it more difficult for sperm to enter the uterus, and endometrium which reduces the chances of implantation.
Pharmacokinetics
Junel fe contraceptive pill pharmacokinetics have not been studied. However, the following information on Junel’s pharmacokinetics regarding norethindrone estradiol and norethindrone citrate is derived from literature.
Absorption
Norethindrone is rapidly and completely deacetylated from norethindrone following oral administration. The disposition of norethindrone has been compared to that of norethindrone orally administered (1). After oral administration, both norethindrone-acetate and ethinyl esteradiol undergo first-pass metabolism. This results in absolute bioavailability at approximately 64% and 43% respectively for norethindrone acetate (1-3).
Distribution
Volume distribution of norethindrone (1-3) varies from 2 to 4 L/kg. Both steroids have a high plasma protein binding (greater than 95%); neither norethindrone nor ethinyl esteradiol binds to albumin or sex hormone bindingglobulin.Junel fe contraceptive pill.
Metabolism
Norethindrone undergoes extensive Biotransformation. This involves a lot of reduction followed by sulfate or glucuronide conjugation. Most metabolites found in the blood are sulfates. However, glucuronides account for the majority of urinary metabolites ((5)). A small amount norethindrone-acetate can be metabolically converted into ethinyl esteradiol. Ethinyl esteradiol is extensively metabolized by both oxidation as well as by conjugation with either sulfate or glucuronide. Urine is dominated by sulfates and glucuronides, which are the main circulating conjugates.
2-hydroxy ethinyl esteradiol is the primary oxidative metabolite. It is formed by the CYP3A4 Ioform of cytochrome P450. The gastrointestinal mucosa is thought to be part of the first-pass metabolism for ethinyl esteradiol. Enterohepatic circulation may be possible for ethinyl estradiol (6).Junel fe contraceptive pill.
Excretion
Both norethindrone (and ethinyl esteradiol) are excreted in urine and feces as metabolites (5-6). The plasma clearance values of norethindrone (approximately 0.4%/kg) are comparable (1-3).
