Ingredients of birth control pills


Birth control pills are pills taken by women every day to prevent pregnancy. Birth control pills work by inhibiting the growth of eggs in a woman's ovaries during her monthly menstrual cycle. So, what ingredients do birth control pills contain?

1. What are birth control pills?


Oral contraceptives have been used by more than 60 million women worldwide and are considered by many to be the most socially significant medical advancement of the twentieth century. Birth control pills are pills that women take every day to prevent pregnancy. Birth control pills do this by inhibiting the growth of an egg in a woman's ovaries during the monthly menstrual cycle.
During a woman's menstrual cycle, low estrogen levels normally trigger the pituitary gland to secrete a hormone that stimulates the development of an egg. Birth control pills release enough synthetic estrogen to keep that hormone from being released during the monthly cycle. Birth control pills also contain a second synthetic hormone, progestin, which increases the thickness of cervical mucus and interferes with the growth of the lining of the uterus to prevent pregnancy.
Studies have shown that birth control pills are 99% effective at preventing pregnancy. The results of studies on the safety of contraception vary. Some studies show that its use increases the risk of certain types of cancer, while others show that risk is minimal. In addition, there are also claims that oral contraceptives increase the risk of stroke and heart attack.

2. Composition of birth control pills


The main ingredients of birth control pills are powders that contain synthetic versions of the hormones estrogen and progestin. Normally, these hormones are made naturally in a woman's ovaries. Birth control pills can contain both of these hormones or only progestin.
Both of these hormones prevent a woman's ovaries from releasing a clear egg (called ovulation). The manufacturer increases the effectiveness of these hormones by altering the levels of the natural hormones the body makes. In it, Progestin is a drug that works to make the mucus around a woman's cervix thick and sticky. This helps prevent sperm from entering the uterus.

3. How are birth control pills made?


Using a process known as wet granulation, the active ingredients - powders containing synthetic versions of estrogen and progestin - are mixed together with a diluent and disintegrating agent (products) dilute the powders and cause them to dissolve in a liquid) in a large number of mixers like the mixmaster found in many kitchens. For larger batches, a device known as a double shell blender can be used.
The binder carrier solutions (the material that will bind the contents of the pellets) are stirred into the dough, which is wetted until the consistency of brown sugar is obtained.
The mass of dough (called wet granules) is pressed through a mesh screen. The moist material is then placed on shallow trays covered with large paper and placed in an oven. The lubricant, in the form of a fine powder, is sieved on the dried material (called dry granules). The lubricant and dry granules are then mixed in a blender, using an agitation operation.
Tablets are formed from a mixture, often using a method known as direct compression. Direct compression uses steel punches and dies in large machines, presses tablets directly from the powder mixture. The physical composition of the powder mixture is not altered in any way. Punching systems are usually computerized.
The pills are tested to ensure compliance with federal regulations and packaged for shipping to pharmacies.

4. Common types of birth control pills


The most common type of birth control pill is a combination of the hormones estrogen and progestin. There are different forms of this pill.
The "mini-pill" is a progestin-only, estrogen-free birth control pill. These pills are an option for women who don't like the side effects of estrogen or who can't take estrogen for medical reasons.
They can also be used postpartum in women who are breastfeeding. All women taking oral contraceptives need to have a checkup at least once a year. Women should also have their blood pressure checked 3 months after starting the pill.
Birth control pills only work well if a woman remembers to take her pill every day and doesn't miss a day. Odds are that only 2 or 3 women out of every 100 who take the Pill correctly for a year get pregnant.

The risk is higher for women who smoke or have a history of high blood pressure, blood clotting disorders or unhealthy cholesterol levels. However, the risk of developing these complications is much lower with either pill than during pregnancy. Regular menstrual cycles should return within 3 to 6 months after a woman stops using most hormonal birth control methods.
