<h2>AHRQ and FDA to collaborate in the largest study ever of possible heart risks with ADHA medications</h2>
<p>Two U.S. Department of Health and Human Services agencies will collaborate in the most comprehensive study to date of prescription medications used to treat attention deficit hyperactivity disorder (ADHD) and the potential for increased risk of heart attack, stroke, or other cardiovascular problems. Researchers supported by the Agency for Healthcare Research and Quality (AHRQ) and the Food and Drug Administration (FDA) will examine the clinical data of about 500,000 children and adults who have taken medications used to treat ADHD to determine whether those drugs increase cardiovascular risks.</p>
<p>Because medications used to treat ADHD can increase heart rate and blood pressure, there are concerns about the drugs' potential to increase cardiac risks. It is also thought these risks may be different for adults and children, but more evidence is needed about the long-term effects of using ADHD medications.</p> <p>The planned analysis follows an FDA-sponsored preliminary study that compiled information from large health care databases on prescription drug use, inpatient care, outpatient treatment, and health outcomes, including death. Based on that effort, researchers identified people who took ADHD drugs during a 7-year period ending in 2005. AHRQ, which sponsors research on clinical effectiveness and safety, will team with FDA to complete the analysis of the data.</p>
<p>The study will be coordinated by Vanderbilt University researchers on contract through AHRQ's Effective Health Care program. Data analysis will be performed by researchers at Vanderbilt, Kaiser Permanente of California, the HMO Research Network and i3 Drug Safety, as well as from FDA and AHRQ. The analysis will
take about 2 years to complete and will include all drugs currently marketed for treating ADHD.</p> <p>The study will analyze the risks of all the drugs as a whole, and risks of the drugs grouped by class. Results are expected to be important not only to patients, their families and health care providers, but also to government insurance programs. Medicaid, Medicare, and the State Children's Health Insurance Program provide reimbursement for drugs prescribed for ADHD.This information could also be used to inform product labeling, which is used by health care providers when making treatment decisions. </p> <p>
ADHD is a behavioral disorder that, in many patients, causes hyperactivity, and may have a significant impact on school performance and social functioning. According to the National Institute of Mental Health, ADHD affects approximately 3 percent to 5 percent of school-age children and about 4 percent of adults. Use of ADHD drugs has increased in recent years among children and adults.</p> <p>A recent AHRQ analysis of medication expenditures found three ADHD drugs&#8212;Concerta, Strattera, and Adderall&#8212;ranked among the top five drugs prescribed for children ages 17 years and younger. About $1.3 billion was spent on those drugs in 2004, the study estimated. </p> <p>
