4. RU 486/PG much more widely tested (thousands versus hundreds).
5. MTX is a generic drug and costs under $5.00. RU 486 is not generic and the cost will be about $350, and
6. manufacturers of MTX and Cytotec oppose using their drugs for abortion. Maker of RU 486 is promoting use for abortion.

Status U.S. tests completed on 2,121 women; licensed to Population Council; marketing stalled by lawsuit against prospective manufacturer; accepted as “safe and effective” by U.S. Food and Drug Administration (FDA).
