How many times stronger is the morning-after pill than standard contraception?

The question is unfortunately posed because emergency contraception differs in composition from contraceptive pills for systematic use. One of the ingredients that is used in emergency contraception is ulipristal acetate. This active compound is not used in standard contraception, so there is nothing to compare: https://www.gdziepolek.pl/substancje/octan-uliprystalu The second substance that can be found in the "after tablet" is levonorgestrel: https://www.gdziepolek.pl/substancje/lewonorgestrel And in the case of contraception after intercourse, a tablet containing 1.5 mg of this compound is taken. However, levonorgestrel is not used alone in oral contraception - it is always combined with estrogen. The combined contraceptive pill uses levonorgestrel as a second ingredient in doses ranging from 0.1 mg to 0.15 mg. Levonorgestrel itself may contain intrauterine systems (spirals) - then they release 0.02 mg of the drug into the uterine cavity within 24 hours.
