Several types of oral contraceptives, or birth control pills, are highly effective at preventing pregnancy. These varieties consist of the traditional pill, which administers hormones for 21 days followed by seven days of placebo, and the extended-cycle pill, which consists of daily hormone administration. Solia is a traditional type of oral birth control pill and is composed of two different hormones that act together to prevent pregnancy.
Ethinyl Estradiol
One of the hormones in Solia tablets is ethinyl estradiol, which is also identified as an estrogen. Estrogen hormones are important regulators of the female reproductive cycle. Ethinyl estradiol works together with desogestrel to trick the ovaries out of their normal ovulating cycle and suspend ovulation so that eggs are not released from the ovaries, explains Drugs.com. This action reduces the opportunity for egg fertilization following sexual intercourse.
Desogestrel
The other hormone found in Solia is desogestrel, which is more commonly known as progesterone, or progestin. Like estrogen, progesterone is a chemical regulator of the reproductive process. The ovaries and other tissues will normally release a lot of these chemical signals when a woman is pregnant, which halts the ovulation process. By taking oral contraceptives such as Solia, these signals are continuous, so the reproductive system is tricked into thinking it is always pregnant.
Inactive Ingredients
As with nearly all oral medications, inactive ingredients are part of the pill formulation and manufacturing process. Common inactive ingredients for tablet-pressed pills include magnesium stearate and cellulose. These chemicals are added as dispersion agents and as a lubricant so that the pills do not stick to the machinery during processing. These ingredients are considered inactive because they do not contribute to any of the activity of the medications, nor do they pose any harm.
