Lederle International

Lederle International appears to have been the international pharmaceutical division or trade name associated with Lederle, a historical pharmaceuticals business within American Cyanamid and later Wyeth. Historical references describe it as sponsoring medical symposia and operating as part of a multinational prescription-drug business rather than as a standalone modern biotech company. The broader Lederle organization was known for marketed pharmaceutical and vaccine products, but specific current pipeline details for Lederle International as a distinct entity are not available. The Lederle business lineage passed through American Cyanamid, then Wyeth/American Home Products, and ultimately became part of Pfizer after Pfizer completed its acquisition of Wyeth in 2009. As a result, Lederle International should be treated primarily as a historical pharmaceutical business name rather than an active independent company.
