Objective: The presence of a dopaminergic function in pituitary and pineal glands is well known. Methylphenidate (MPH), a widely prescribed psychostimulant for attention deficit/hyperactivity disorder, is an indirect dopamine agonist which could have the capacity of influencing the hypothalamo-neurohypophysial system with the pineal gland. Our aim is to investigate dose-dependent immunohistochemical dopamine 2 expression, possible cell apoptosis and ultrastructural changes of the rat pituitary and pineal gland tissue, to demonstrate possible toxicity of the chronic extended use of the MPH.
