Clinical Trial Summary

Lack of appetite and weight loss are a common side effect of ADHD therapy with amphetamines such as methylphenidate. Lack of sufficient food intake has been shown to have negative effects on weight and height as well as learning and memory.

There is no current treatment to prevent this loss of appetite except discontinuation or reduction of the methylphenidate. Discontinuation or reduction of the drug can cause the return of ADHD symptoms.

The purpose of this study is to compare the effects, good and/or bad, of two doses of a drug, cyproheptadine, vs placebo to find out if cyproheptadine prevents the appetite suppression associated with methylphenidate.

- Laboratory results, including serum chemistries, hematology, and urinalysis, must show no clinically significant abnormalities (clinically significant is defined as laboratory values requiring acute medical intervention, indicating a serious medical illness, or requiring further medical evaluation in the judgment of the investigator)

- Patients and parents have been judged by the investigator to be reliable to keep appointments for clinic visits and all tests, including venipuncture, and examinations required by the protocol.

- Patients who have any medical condition that would increase sympathetic nervous system activity markedly (for example, catecholamine-secreting neural tumor), or who are taking a medication on a daily basis (for example, albuterol, inhalation aerosols, pseudoephedrine), that has sympathomimetic activity. Such medications can be taken on an as-needed basis

- Presence of contraindications for methylphenidate or cyproheptadine hydrochloride
