Methylphenidate: increased abuse or appropriate use?

Abstract

To address the question of the significant increase in methylphenidate (MPD) prescriptions being written and to make recommendations for health care providers involved in providing care for patients with attention deficit hyperactivity disorder (ADHD) and their families. Medline search 1966-1998 for professional articles using the following search terms--methylphenidate, children, adolescents, abuse; Internet search using MPD, Ritalin, and ADHD; and Paper Chase search using methylphenidate. The available literature regarding potential abuse or diversion of MPD consists of case reports, review articles, newspaper articles, and a Drug Enforcement Administration (DEA) publication. All available literature sources were used. Although the media and DEA report significant abuse and diversion of prescribed MPD, a review of the available literature did not reveal data to substantiate these claims. Nonetheless, there are reasons to suspect that abuse and diversion occur. A potential contributing factor to abuse is the reported similarities in pharmacodynamics and pharmacokinetics between MPD and cocaine. Recommendations are made to decrease the possibility of abuse and diversion of prescribed MPD. A balanced middle ground must be found regarding the benefits of MPD and its abuse potential. Education of clinicians, patients, and family members is key in ensuring that MPD is used appropriately.
