According to the General Accountability Office inquiry, 28 drug products had price increases over 100% in 2000, in 2008 71 drug products had such large increases. Medicines like Adderall for attention deficit disorder, Inderal for chest pain, Sumycin for infections were in the list of 416 brand name drug products where makers or distributors raised prices at least once by 100% or more for period 2000-2008. As large pharmaceutical companies sold their marginally profitable drug products or small selling products to smaller companies, these smaller companies would immediately increase prices to recover the money they paid to the large pharmaceutical companies. 26 of the brand name products saw prices raised 10 fold. A third of the drugs with large price increases treat depression and disorders of the central nervous system.
