Could someone please comment on which drug(s) is/are the ECP/morning-after pill and their specific functions?

Cheers,

in general, if sex was in preovulatory period morning after pills would suppress ovulation, also they increase endometrium motility, so that fertilized egg is not able to implant

I had remembered hearing somewhere that mifepristone/methotrexate was the combo used for the morning after pill, but that high-dose progesterone could also be used.

I've done some reading online, and mifepristone/methotrexate is the combo used to carry out abortions during the first-trimester, and levonorgestrel is used as the morning after pill. Mifepristone, both according to GT and an online source, although it can be used as an ECP, is generally not regarded as the med used for this purpose.
 
yup, mifepristone is generally used for early abortion (up to 6-8 weeks).

as for morning after pills:
most common is levonorgestrel.
also according to Yuzpe method combination of estrogen and progesterone can be used.
one of the extreme methods is copper intrauterine devices, but they are mostly used as regular contraception, not emergency

Mifepristone and methotrexate are used for medical abortions. Period. The morning after pill is strictly contraceptive - just like what's in regular oral contraceptives, just higher doses. In fact, women who have oral contraceptives can just take a handful of them - I can't remember if it's 10 doses or just finish the pack - if they don't have access to Plan B. I guess you call that Plan C.
 
At least according to FA mifepristone/ misoprostol is more common for abortions and metotrexate is more for choriocarcnima?
 
The morning after pill is pretty controversial in the United States. It is very unlikely to be on your exam. The closest they're going to get is mifeprostone inducing termination of pregnancy as an unwanted side effect.
