The Bureau of Medicine's interest in increasing efficiency for clearing new drugs and distributing work among staff members led to yet another restructuring in 1965. The new Bureau consisted of five Divisions and the Office of the Medical Director (still Sadusk). The five Divisions were New Drugs (Smith); Medical Review (Howard Weinstein); Medical Information, formerly the Division of Research and Reference (Donald Levitt); Veterinary Medicine (Charles Durbin); and Antibiotic Drugs (Raymond Barzilai). The Division of Antibiotic Drugs continued to evaluate antibiotic NDAs, but certification of antibiotics remained in the Bureau of Scientific Standards and Evaluation. The Medical Advisory Board also was established at this time to advise FDA on the problems faced by the industry, the medical community, and other health-related areas. Sadusk chaired the Board, and its members included leaders in medicine, pharmacology, dentistry, and veterinary medicine from across the country.
