Conversely, when <strong>FDA</strong> becomes aware through <strong>the</strong> awlication review processthat an awroved drug prodoct is being re-marketed, it will again beincluded on <strong>the</strong> List.Consistent with our p::>licy to include only currently marketed prescriptiendrug prodocts, approved antibiotic prodocts will be listed only after <strong>the</strong>initial batch has been certified for marketing.3. Multisource and single source drug products are included on <strong>the</strong> List.In constrocting <strong>the</strong> List, <strong>FDA</strong> has evaluated for <strong>the</strong>rapeutic equivalenceonly multisource drug prodocts, i.e., those pharmaceutical equivalentsavailable from more than one manufacturer. For all mul tisource products a<strong>the</strong>rapeutic equivalence code is included and, in additien, those prodoctswhich are <strong>the</strong>rapeutically equivalent are highlighted in bold face and underlined.Those prodocts with awroved applicatiens that are single source arealso included on <strong>the</strong> List for <strong>the</strong> sake <strong>of</strong> completeness, but no <strong>the</strong>rapeuticequivalence code is included with such prodocts. The details <strong>of</strong> <strong>the</strong>se codesand <strong>the</strong> p::>licies underlying <strong>the</strong>m are discussed in Section F.4. Products on <strong>the</strong> List are identified by <strong>the</strong> names <strong>of</strong>·holders <strong>of</strong> approvedapplications.The products en <strong>the</strong> List are identified by <strong>the</strong> names <strong>of</strong> <strong>the</strong> holders <strong>of</strong>awroved awlicatiens, ra<strong>the</strong>r than by <strong>the</strong> names <strong>of</strong> <strong>the</strong> actual manufacturers<strong>the</strong>mselves. This is because <strong>the</strong> awlicatioo holder may have, for example,had its prodoct manufactured by a contract manufacturer and may simply bedistr ibuting <strong>the</strong> product for which it has obtained awroval. In mostinstances, hCMever, <strong>the</strong> manufacturer <strong>of</strong> <strong>the</strong> prodoct is <strong>the</strong> awlicationholder.Although <strong>the</strong> products on <strong>the</strong> List are identified by <strong>the</strong> names <strong>of</strong> <strong>the</strong>holders <strong>of</strong> awroved awlicatioos, several circumstances, such as changingcorp::>rate pr<strong>of</strong>iles, have made this determination a difficult one. However,based en intensive and continuing document reviews and en concurrencethrough corrmunicatioo with firms, <strong>the</strong> awlicatioo holder designatioos en <strong>the</strong>List, in most cases, are correct.As a general rule, <strong>the</strong> products 00 <strong>the</strong> List are not identified by <strong>the</strong>names <strong>of</strong> <strong>the</strong> distributors <strong>of</strong> those prodocts. <strong>FDA</strong> does not believe that<strong>the</strong>re is a feasible way at this time to maintain an up-to-date and canpletelist linking <strong>the</strong> prodocts <strong>of</strong> each awroved awlication holder with <strong>the</strong>distributors and relabelers handling those products. Products subject to anawroved application are frequently manufactured for distributors, under <strong>the</strong>distr ibutor I s labeling, for marketing by <strong>the</strong> distributor. Because <strong>the</strong>sedistributors <strong>of</strong>ten shift <strong>the</strong>ir source <strong>of</strong> suWly in <strong>the</strong> carmercialmarketplace without informing <strong>FDA</strong>, even if <strong>FDA</strong> were to attempt to expand <strong>the</strong>List to link distributors with holders <strong>of</strong> approved applicatiens, it \'K)uldnot have ready access to <strong>the</strong> information necessary to do so.I - 7
