- Zucker mice don't have to have a life outside their cages. Most
- people here do, though I sometimes have my doubts. Mifepristone
- can be a very toxic drug outside of its use as an abortifacient.
-
- Administrating RU-486 (mifepristone) to induce abortion explots its
- actions as an antiprogestational agent. Progesterone is a female
- hormone which prepares the endometrium of the uterine wall for
- implantation by the fertilized egg and maintains it as the embryo
- develops. Administering an antiprogestogen like mifepristone
- causes the endometrium to slough off, rather like an early
- miscarriage. A dose of prostaglandin is given after mifepristone
- to help expel the uterine contents. As you see, this use of
- the drug is quite short term; one or two doses over a period of
- a few days at most. What's more, this really isn't designed for
- once-a-month administration--it's more like a 'days-after' pill
- of last resort, in preference to a surgical abortion. This is why
- the drug is relatively safe.
-
- This use of the drug mostly ignores its other unrelated effects,
- most notably its anti-glucocorticoid actions (that is, it competes
- for certain "cortisone receptors" in cells. The net effect of
- is a kind of cellular "Addison's Disease"--your adrenal glands
- are pumping out corticosteroids as fast as they can make 'em,
- but they're blocked from having much of any effect (well, any
- glucocorticoid effect--I'd imagine that sodium and water retension
- due to the hypercorticoid state might be severe, but that's just
- conjecture.) This is not Good Stuff. It doesn't matter all that
- much if it's given once and that's it for a while, as you seen in
- its used to cause abortion, but any kind of chronic administration
- needs to take these effects into mind.
-
- I think its role in treating human obesity is next to nil right now,
- and remains to be determined, if it ever will be at all. Calling
- it a "weight loss drug" on the basis of experiments with certain
- genetically obese mice is pretty, well, wishful thinking.
-
- >RU-486's potential social and fiscal consequences dwarf the abortion aspects.
-
- You mean Durk and Sandy get rich while they pitch it as a Life
- Extension (tm) drug.
