ang misoprostol (generic name) talaga is used for treating ulcers AND miscarriage. kaya ginagamit din siya to induce abortion. as for being banned in the country, I'm not sure if it is indeed banned now but I'm sure a few years ago hindi pa yan banned, just very very heavily regulated. pero up until now, some pharmacies do still have it in stock (both cytotec and generic versions)
also, its not just plain cytotec, some other medicines like arthrotec (used to treat arthritis and ulcer), also contain misoprostol. but again because of the effects of misoprostol, this was being used to induce abortion so this was either discontinued or no longer being sold here
