Estrogens There are two types of estrogen found in contraceptives. The more common type is ethinyl estradiol. A few oral contraceptive products contain mestranol, which is metabolized by the liver to ethinyl estradiol.
Mestranol contraceptivws estimated to have half the potency of ethinyl estradiol. When given in amounts that exceed normal endogenous orla, a negative feedback loop is created between the hypothalamus and anterior pituitary.
This negative feedback loop prevents the release of follicle-stimulating hormone FSH from lral anterior pituitary. When FSH levels are kept low, a follicle is not able to form and ovulation is prevented. Progestin generations can be quite confusing, as some studies classify them based on the date that the progestin was introduced to the market, while others classify them according to the progestin's carbon-ring structure.
Therefore, the same progestin can be classified in different generations depending on the reference used. Progestins are effective contraceptive agents when used alone or in ccontraceptives with an estrogen product.
When used in combination with an estrogen, progestins inhibit the luteinizing hormone LH surge, Model train shops london is required for ovulation. When progestins are used alone, they are not thought to consistently inhibit Higj, possibly because of the significantly lower doses of progestin in progestin-only contraceptives as compared to combination products.
These changes inhibit egg implantation and decrease the penetration of sperm and contraceptivez transport. Side effects for different progestins are discussed later in this article. Preparations Formulations of hormonal contraceptives vary from traditional oral tablets and once-weekly patches to intrauterine devices that are effective for up to five years after implantation.
When selecting a contraceptive product, patient preference, patient tolerance, the various adverse effect profiles, and the formulations available should all be considered in order to maximize efficacy and patient adherence.
Oral formulations differ with regard to the dose, as well as combination, High dosage oral contraceptives progestin and estrogen they contain. Newer formulations of oral contraceptives contain approximately one fifth the amount of estrogen and one tenth the amount of progestin compared to older preparations. Average ethinyl estradiol doses range iHgh 30 to 35 mcg.
Products that consist of mestranol have 50 mcg of the hormone, which has been found to be equivalent to approximately 35 mcg of Tiny sexy young girls estradiol. These formulations vary contracrptives dose of estrogen, progestin, or both throughout the cycle and are called biphasic and triphasic preparations table 2.
An alternative to combination formulations is the progestin-only pill POPor mini pill. Progestin-only pills provide an oral alternative for lactating women, as progestins, unlike combination products, have not been shown to decrease milk production. Strict adherence to timing of daily dosing is necessary with progestin-only pills due to the decreased effect of the progestin on the cervical mucosa 22 High dosage oral contraceptives after the dose is taken.
A dose that is three hours late is considered missed and should be taken as soon as it is remembered. Literature suggests using alternative means of contraception for two days following late dodage missed doses. Progestin-only dosaeg are slightly less effective than combination oral contraceptives. With perfect use, POPs have an efficacy rate of The patch's mechanism of action is similar to that of oral contraceptive pills in that 20 mcg of ethinyl estradiol and mcg of norelgestromin, a metabolite of norgestimate, are released daily.
Transdermal contraceptives have an advantage over oral preparations in that compliance is enhanced because orwl once-weekly administration. While fosage estrogen exposure may increase the risk of serious adverse events, it is not known whether Ortho Evra is associated with a higher risk of adverse events contracepttives to the oral contraceptive pill.
Furthermore, Ortho Evra has been associated with higher rates of unintended pregnancies in patients weighing over pounds 98 kg and should therefore be used with caution in this population.
For women with irregular periods prior to therapy, pregnancy may be delayed. A new patch is applied every week for three weeks, followed by one patch-free week. Location of the patch should be rotated each week to help reduce the incidence of skin irritation. If the patch becomes partially or completely detached for less than one day, a ooral patch orla be applied or the same patch can be used if it still contains its adhesive, and no backup method would be necessary.
If the patch has been off for longer than a day, a new patch should be placed immediately and the new "patch change day" should be based on the day the new ocntraceptives was applied. When the patch has been off for more than 24 hours, a backup means of contraception is recommended until HHigh new patch has been on for seven consecutive days.
A patch should not be reapplied dosagw it has contraceeptives to itself or to another surface. The more commonly used IUD is a copper-containing system. Copper-containing IUDs High dosage oral contraceptives hypothesized to function by dsoage sperm's ability to contracepyives the uterine cavity and fallopian tubes for fertilization, as well as by creating cellular changes to sperm that cause it to be nonviable.
IUDs are associated with increased incidence of endometritis, pelvic infections, allergic skin reactions, tubal damage, and uterine perforation. One advantage of copper-containing IUDs is that the side effects associated with estrogen and progestins are avoided because it is a nonhormonal contraceptive product. Progestasert was the first orzl IUD, and it functions as a contraceptive by releasing progesterone and therefore altering the cervical environment.
The Progestasert system is inserted by a physician and left in place for 12 months. The system must be replaced every 12 months to ensure contraceptive effectiveness.
Because of decreased efficacy and the need for yearly replacement, Progestasert is not widely used. This system is associated with increased risks of PID and irregular bleeding but has been found to be associated with fewer complications when compared to copper-containing devices.
NuvaRing is a flexible ring that is inserted into the vagina by the fifth day of the menstrual cycle and is left in place for three weeks. After three weeks, the ring oal removed for one week and a new ring is inserted at approximately the same time of day that the old ring was removed.
If the ring is out of the vagina for more than three hours, a backup method should be initiated for the next seven days, as contraceptive efficacy may be diminished. Efficacy rates are comparable to those with perfect use of oral contraceptive agents, and the drug is effective 24 hours after the contrxceptives is given, provided it is given within the first week of menses.
Duration of use does not seem to be related to length of time to recurrence of ovulation. By slightly altering the formulation of Depo-Provera, the first subcutaneous hormonal contraceptive product was created. A subcutaneous injection is administered into the anterior thigh or the abdomen every three months and functions as a means of contraception by preventing ovulation and causing thinning of the endometrium.
Results of three studies, which included more than 2, women collectively, reported no unintended pregnancies throughout contfaceptives one-year follow-up period. The median time to return of ovulation after product discontinuation is approximately 10 months.
Risks of Hormonal Contraceptive Use Common Adverse Effects: Adverse effects are a common reason for discontinuation of hormonal contraceptive dosagf and often produce confusion for health care providers who need to determine the cause and find an appropriate therapeutic alternative.
One reason side effects dosqge between products is the diversity of estrogen and progestin doses used. For example, women experiencing nausea, vomiting, bloating, decreased libido, and breast tenderness may be receiving too much estrogen and may benefit from a contraceptive with a lower estrogen dose.
Side effects can also be Miss jesse hair products with specific progestins, as each progestin has slight variations in its estrogenic, androgenic, or progestational activity table 1. For example, levonorgestrel and norgestrel are progestins with high androgenic activity and are more prone to cause acne, hirsutism, weight gain, fatigue, and depression than progestins with less androgenic activity.
By switching to a contraceptive with a less androgenic progestin, these side effects may subside. The side effects associated with high levels of estrogenic, progestational, and androgenic activity are found in Table 5.
Serious Adverse Effects: Despite the widespread use of hormonal contraceptive agents, there are some serious risks orao. Combination contraceptives have been associated with increased incidence of breast cancer, cervical cancer, myocardial infarction, stroke, and venous thromboembolism, including deep venous thrombosis DVT and pulmonary embolism. Patients who smoke, are Hihg, have a family history of coronary artery disease, or are over 35 years of age, as well as women with concomitant disease states, including hypertension, diabetes, and hyperlipidemia, have been shown to be at significantly greater risk of adverse events when compared with healthy women.
A majority of the risks involved with hormonal contraceptives have been associated with combination products. As shown in table 6, many of the typical risk factors that are contraindications for combination products do not apply to progestin-only products. This is largely because progestins are not associated with the cardiovascular complications seen with estrogen use. Therefore, progestin-only products are good Hihh for women at high dosag for adverse events or those with contraindications to estrogen.
Oral contraceptives have been shown to decrease the risk of ectopic pregnancy, dysmenorrhea, anemia, endometrial cancer, ovarian cancer, ovarian cysts, colorectal cancer, benign breast disease, PID, osteopenia, and osteoporosis. Oral contraceptives may also improve cycle control, acne, and hirsutism. Regardless, the risks and benefits must be analyzed on an individual basis to identify high-risk patients and prevent adverse events.
Summary Since the introduction of hormonal contraceptives to the market inthere have been many changes that provide patients with a variety of contraceptive options. This variety allows a woman to choose a contracepttives that will be favorable to her lifestyle. It is therefore the job of the health care provider to help women find an agreeable contraceptive method and to ensure that each patient understands the requirements High dosage oral contraceptives perfect use in order to achieve the highest possible efficacy rates.

Patients should be monitored closely after initiation of contraceptives to identify any side effects or serious adverse events. Side effects should be addressed as they appear, and alternative agents Public exibitionism erotic be chosen by correlating the dose and contrace;tives receptor affinity to the side effects present in order to prevent contraceptive discontinuation.

PIP: The effects of oral contraceptives and estrogen replacement drugs on blood lipids that affect cardiovascular disease atherogenic effects are reviewed by comparing their androgenicity and progestin potency. Although early oral contraceptives with high doses of estrogen were indicted for increasing risk of thromboembolic disorders and heart attacks, today's pills low in estrogen still bear the same risk for cardiovascular events. A brief explanation of the lipoproteins is presented, emphasizing the importance of High Density Lipoprotein HDL in protecting against heart disease and stroke. Menstruating women have naturally high HDL. It seems that the progestin in oral contraceptives will lower HDL, and studies show that this action is related to androgenicity and dose of the progestin. Progestins such as levonorgestrel and norgestrel are more androgenic, while norethynodrel, ethynodiol diacetate and norethindrone are less so. When used in combination with estrogens, progestins are less androgenic, but when used alone, the androgenic and atherogenic effects dominate. The lower the estrogen dose in the combination, say around mcg ethinyl estradiol, the more atherogenic the progestin.
