Many Americans use prescriptions drugs daily; however, the abuse of such drugs has become a widespread problem in the USA. There are steps a patient can take to ensure the appropriate use of prescription medications. Patients should always follow the directions, be aware of potential interactions, never stop or change a dose on their own, and never take another person’s prescription. Patients should also inform their healthcare professionals about current prescription and OTC medicines they are taking, along with any dietary or herbal supplements they might be taking.
What are the concerns?
A number of published reports indicate that prescription drug abuse is on the rise in the United States. According to the 2003 National Survey on Drug Use and Health, 6.3 million Americans aged 12 and older have used prescription medications for nonmedical purposes in the prior 30 days.
An estimated -
- 4.7 million used pain relievers
- 1.8 million used tranquilizers
- 1.2 million used stimulants
- 0.3 million used sedatives
The number of new non-medical users of pain relievers increased drastically-from 573,000 in 1990 to 2.5 million in 2000. Overall, men and women have roughly similar rates of non-medical use of prescription drugs (an exception is found among 12-17-year-olds, with more females likely to abuse these drugs).
The Drug Abuse Warning Network (DAWN), which monitors drug mentions (medications and drugs of abuse) from emergency departments (EDs) across the Nation, recently reported that two of the most frequently mentioned prescription medications in drug abuse-related cases are benzodiazepines (e.g., Valium, Xanax, Klonopin, and Ativan) and opioid pain relievers (e.g., oxycodone, hydrocodone, morphine, methadone, and combinations that include these drugs). In 2002, benzodiazepines accounted for 100,784 ED visits categorized as drug abuse-related cases and opioid pain relievers accounted for more than 119,000. Between 1994 and 2002, ED reports of hydrocodone and oxycodone overdoses increased by 170 percent and 450 percent, respectively. While ED visits attributed to drug addiction have been increasing, suicide-related visits have remained stable since 1995.
What types of prescription medications are commonly abused?
Several classes of medications that are commonly abused include opioids, central nervous system (CNS) depressants, and stimulants. Certain over-the-counter (OTC) medicines can also be abused when not taken as directed. It is important to note that many prescription drugs or OTC medications can produce dangerous health effects when taken concurrently or taken with alcohol.
Opioids. Opioids are commonly prescribed to treat pain. Examples of prescription opioids include morphine (Kadian, Avinza), codeine, oxycodone (e.g., OxyContin, Percodan, Percocet), hydrocodone (Lortab, Lorcet, Vicodin), propoxyphene (Darvon), fentanyl (Duragesic), and hydromorphone (Dilaudid). Opioids work in the brain to diminish the perception of pain. Opioids also can produce a sense of euphoria by affecting pleasure centers in the brain. This is often intensified when opioids are taken by routes other than those prescribed.1 For example, OxyContin can be crushed and snorted, or injected intravenously-this can enhance the euphoric effects, while at the same time increasing the risk for serious medical consequences, such as overdose.
CNS Depressants. CNS depressants commonly are prescribed to treat anxiety and sleep disorders because of their ability to slow normal brain function. These medications include barbiturates, such as mephobarbital (Mebaral), pentobarbital sodium (Nembutal), butalbital (Fioricet), and benzodiazepines such as diazepam (Valium), chlordiazepoxide HCl (Librium), alprazolam (Xanax), triazolam (Halcion), and others.
Stimulants. Stimulants, including dextroamphetamine (Dexedrine and Adderall) and methylphenidate (Ritalin and Concerta), are used primarily to treat attention deficit hyperactivity disorder, attention deficit disorder, and narcolepsy. These stimulants increase the amount of certain chemicals in the brain and peripheral nervous system. This can lead to increased blood pressure and heart rate, and increased blood glucose.
Who is most vulnerable?
Adolescents. According to the 2003 National Survey on Drug Use and Health, 9.2 percent of youth aged 12-17 had used a prescription psychotherapeutic drug for nonmedical reasons in the past year and 4.0 percent were current users. Prescription opioids are a particularly serious problem in this age group. NIDA’s 2004 Monitoring the Future survey of 8th-, 10th-, and 12thgraders found that 5.0 percent of 12th-graders reported abusing OxyContin in the past year, and 9.3 percent reported abusing Vicodin, making Vicodin one of the most commonly abused prescription drugs in this population. Another troubling trend is the recent phenomena known as “pharming,” where young people mix prescription medications and ingest some or all of them at once, unaware of potentially severe drug interactions.
Elderly Adults. Although persons 65 years of age and above comprise only 13 percent of the population, they are prescribed approximately one-third of all medications in the United States. In addition, older patients are likely to be prescribed more long-term prescriptions, as well as multiple prescriptions, which could potentially result in unintentional misuse. A large percentage of older adults also use OTC medicines and dietary supplements, along with prescription medications, which could lead to dangerous results. The elderly also are at risk for prescription drug abuse, in which they intentionally take medications that are not medically necessary. Because of high rates of comorbid illnesses among the elderly, changes in drug metabolism with age, and the potential for drug interactions, prescription and OTC drug abuse or misuse can have more adverse health consequences among this age group.
What are the treatments for prescription drug abuse?
Years of research have shown that addiction to any drug, illicit or prescribed, like other chronic diseases, can be treated effectively. However, no single type of treatment is appropriate for all individuals with addictions. To be successful, treatment must take into account the type of drug used as well as the needs of the user. Treatment may incorporate several behavioral and pharmacological components, as well as detoxification. Because drug abuse is a chronic and relapsing disease, multiple courses of treatment may be needed for patients to make a full recovery.
There are two main categories of drug addiction treatment- behavioral and pharmacological.
Pharmacological Treatment
Some addictions, such as opioid addiction, can be treated with medications. Methadone and buprenorphine currently are used to treat heroin addiction, but they also may prove useful in treating addiction to pain relievers. Further research is needed to determine whether these medications will provide an effective treatment for prescription drug abuse.
Research shows that a combination of both behavioral and pharmacological treatments is the most effective strategy, especially for treating opioid addiction.
Behavioral Treatment
Behavioral drug abuse treatments such as individual counseling, group or family counseling, contingency management, and cognitive-behavioral therapy-teach patients how to stop using drugs, how to handle cravings, how to prevent a relapse, and how to handle a relapse if one should occur. When delivered effectively, behavioral treatments also can help patients improve their personal relationships and ability to function at work and within the community.
