Rick - I believe that compiling a list or table of drug interactions would be a stupendous undertaking with the volume of both prescription and non-prescription medicines that are on the market today. Not only would the types have to be tabulated but amounts and frequency would have to be considered and to top it all off different people react differently to different drugs. Medicines are something we parkies have to live with until a better "cure?" is found and I , personally believe it will be in the area of transplant. The drug market is much too lucrative for the pharmeucetical (sp?) companies to devote their efforts to developing a cure which will have the ultimate effect of eliminating their market. I aminterested in your forthcoming test program and hope that you will post reports on this BB.....ED H
