329Mr. Steiger. Assuming that Perse is what it appears to be and youtested it to your satisfaction, would you still feel the same aboutmethadone ?Dr. Davidson. No.Mr. Steiger. That is what I wanted.Was there a uniformity in the substance, itself, were you able toexamine the substance on any kind of qualitative basis, microscopicallyorDr. Davidsox. Well, I visited Dr. Revici a number of times. Helikes Chinese food and so do I. We discussed this, but. you know, he isa kind of experimental scientist, and each dosage unit is different, soI think I noted in my paper that patients aren't treated with standardamounts and this made for some difficulty in that we must reallyproperly evaluate this medication.Mr. Steiger. I see. Did you ever observe the effects on somebodywho was intoxicated from alcohol ?Dr. Da\t[dsox. No. I haven't.Mr. Steiger. Thank you. Mr. Chairman.Chairman Pepper. Mr. Winn.Mr. Winn. Thank you, Mr. Chairman.On the memorandum that was furnished us. you said about35, and I think you sent 45 to 50 patients down to Dr. Revicinow. and that was effective in about ,50 percent of your patients. Thenyou got to talking about the withdrawal and maybe I didn't catch it,l3ut how many of these 45 or 50 have you actually witnessed, whetherthey experienced withdrawal symptoms, or not?Dr. Davidson. I have seen about 10 of them during the period oftreatment.Mr. Winn. And you don't have any followup on the ones that youwere able to followup on? Were any of those 10—would any of those10 be included in the ones that you were able to follow up ?Dr. Davidson. Yes.Mr. Winn. I think it is exceptionally discouraging—that is probablynot the right word—that you haven't been able to follow up inone way or the other, or have a med student or someone follow up onthe other patients, because really 45 or 50. I suppose to you miglit bevery indicative of how good Perse is, but I don't think FDA or anyoneAvould call that really a true, true test, probably as far as numbersare concerned, compared to Dr. Revici's experience.Dr. Davidson. That is true; but I just don't have the facilities fordoing it. I have to depend on the patient coming back.Mr. Winn. I think it would enter into the overall picture whetherthey are detoxified, or it would give me a better idea if you had ahundred out of a hundred. "\'\nien we send out a questionnaire to150.000 people, if we got only 12 answers back we wouldn't feel like wegot a total picture.Mr. Rangel. Will Mr. Winn yield ?Mr. Winn. Yes.Mr. Rangel. I think the evidence submitted by the doctor here wasmerely supportive of what had already been submitted by Dr. Revici.So I do believe that he has much more followup of the type that certainlyI would be looking for rather than just relying on this.60-296—71—pt. 1 22
