The IOC executive board disqualified the entire team, the fourth gold and sixth overall medal stripped from that U.S. track contingent in the past eight months for doping.
Three gold and two bronze were previously removed after Marion Jones confessed to using performance-enhancing drugs.
Saturday's decision was almost a formality after Pettigrew gave up his gold medal in June. He admitted in court in May that he used EPO and human growth hormone from 1997 to 2003.
Five of Pettigrew's teammates also lose their medals: Michael Johnson and twins Alvin and Calvin Harrison ran in the final; Jerome Young and Angelo Taylor ran in the preliminaries.
