In a message dated 97-10-05 10:17:06 EDT, you write: << the compound (Madopar) is literally interchangeable with Sinemet, >> I find that hard to swallow..er.. believe. But I shall reserve further opinion on this until I can look at the chemistry of Madopar in vitro and in vivo. I have not been able to track it down in the USP, logically since it is not an approved drug in the US, nor is it in the Merck manual. The Web has not been particularly useful to me because my system is too meager for the emerged and still emerging 21st century information data road... Ciao until then... Michel Margosis
