This information comes from Frank Brown, the very knowledgable moderator of the Southern California IBS group, who gets his information directly from Glaxo-Wellcome, (ho may become sponsors of our group), rather than published reports. "Glaxxo's initial testing on men was small and the same dosage as women. The company now believes that men may need a larger dose and are currently doing tests on it. The early results are good." That is why you cannot fly off the handle when a reporter writes something in a paper that he/she gets from different sources.
