There were 7. By the late s, the patent on its main source of revenue, a morphine pill for cancer patients called MS Contin, was running out. Executives anticipated a massive loss of revenue as generic versions drove down the price of MS Contin, according to internal company correspondence from the period.
The company was focused on finding a new moneymaker. In a memo, Robert F. Kaiko, vice president for clinical research, laid out why it was important to develop a second painkiller. In this memo, Robert Kaiko, the scientist who would go on to help invent OxyContin, explains why Purdue needs another painkiller.
In MS Contin, the technique made morphine last eight to 12 hours. Kaiko and his colleagues decided to use it on an old, cheap narcotic, oxycodone. Sold under several names and formulations, including Percocet and Roxicodone, oxycodone controls pain for up to six hours. Goldenheim,then-vice president of scientific and medical affairs, wrote in a court declaration.
At a meeting, Purdue executives described how OxyContin could "cure" the "vulnerability" of generic competition and laid out how they planned to market the drug. The first patients to use OxyContin were women recuperating from abdominal and gynecological surgery at two hospitals in Puerto Rico in In the clinical study, designed and overseen by Purdue scientists and paid for by the company, 90 women were given a single dose of the drug while other patients were given short-acting painkillers or placebos.
None of the women were regular users of painkillers, so they were more susceptible to the effects of narcotics. Even so, more than a third of the women given OxyContin started complaining about pain in the first eight hours and about half required more medication before the hour mark, according to an FDA analysis of the study. The study found that OxyContin was safe, relieved pain and lasted longer than the short-acting painkillers.
Purdue moved ahead on two paths: seeking patents for its new drug and running additional clinical trials to secure FDA approval.
In study after study, many patients given OxyContin every 12 hours would ask for more medication before their next scheduled dose. A Tennessee pain specialist whom Purdue selected to field-test the drug in as part of the FDA approval process eventually moved 8 of 15 chronic pain patients to 8-hour dosing because they were not getting adequate relief taking the drug twice a day.
Robert Reder wrote to the Memphis physician, using medical shorthand for hour dosing. Narcotic painkillers work differently in different people. Some drug companies discuss that variability on their product labels and recommend that doctors adjust the frequency with which patients take the drugs, depending on their individual response.
The morphine tablet, Kadian, manufactured by Actavis, is designed to be taken once a day, but the label states that some patients may need a dose every 12 hours.
It did not test OxyContin at more frequent intervals. To obtain FDA approval, Purdue had to demonstrate that OxyContin was safe and as effective as other pain drugs on the market. Under agency guidelines for establishing duration, the company had to show that OxyContin lasted 12 hours for at least half of patients. Purdue submitted the Puerto Rico study, which showed that. Officials at the agency declined to be interviewed. After OxyContin hit the market in , ads in medical journals left no ambiguity about how long it lasted.
A spotlight illuminated two dosage cups, one marked 8 AM and the other 8 PM. She had struggled with back pain since age 14, when she was thrown from a horse while practicing for an equestrian competition.
On that day in , her physician said he had something new for her to try. He told her to take OxyContin every 12 hours. Only the next pill would relieve her suffering.
The change had little effect. For a year and a half, she spent each day cycling through misery and relief. Sometimes, she said, she contemplated suicide. Before OxyContin, doctors had viewed narcotic painkillers as dangerously addictive and primarily reserved their long-term use for cancer patients and the terminally ill. Purdue envisioned a bigger market. Sales reps pitched the drug to family doctors and general practitioners to treat common conditions such as back aches and knee pain.
With Percocet and other short-acting drugs, patients have to remember to take a pill up to six times a day, Purdue told doctors.
The marketing succeeded in ways that astonished even Purdue executives. It dwarfed them. The success of OxyContin brought a whole new level of wealth. Other drug companies began marketing their own narcotic painkillers for routine injuries. OxyContin accounted for a third of all sales revenue from painkillers that year, according to industry data. Rates of addiction and overdose have soared alongside the rise in prescriptions. News coverage of these problems in Appalachia and New England in the late s made OxyContin notorious.
Purdue dispatched representatives to Virginia, Maine and elsewhere to defend its drug. They blamed misuse of OxyContin and insisted their pill was a godsend for pain sufferers when taken as directed. David Haddox, told a reporter in The U. Justice Dept. The company eventually rolled out a tamper-resistant version of the painkiller that was harder to crush and snort.
