Furthermore, there were massive repercussions and lawsuits to Purdue following the release of the drug. They would not have taken 5 years to correct the mistake and contain the profit lost. Another explanation might be: oxycodone had been growing more popular with cheaper generics. OxyContin came and promised an instant high. Oxycodone’s reputation following the incident probably left it a popular choice for users, regardless of whether Purdue corrected OxyContin’s design flaw.
