The new pills contain the highly addictive painkiller hydrocodone, packing up to 10 times the amount of the drug as existing medications such as Vicodin. Four companies have begun patient testing, and one of them — Zogenix of San Diego — plans to apply early next year to begin marketing its product, Zohydro.
Critics say they are especially worried about Zohydro, a timed-release drug meant for managing moderate to severe pain, because abusers could crush it to release an intense, immediate high. OxyContin, introduced in 1995 by Purdue Pharma of Stamford, Connecticut, was designed to manage pain with a formula that dribbled one dose of oxycodone over many hours.
Oxycodone is now the most-abused medicine in the United States, with hydrocodone second, according to the Drug Enforcement Agency. It belongs to family of drugs known as opiates or opioids because they are chemically similar to opium. They include morphine, heroin, oxycodone, codeine, methadone and hydromorphone.
After a while, opiates stop working, forcing users to take stronger doses or to try slightly different chemicals.
