Methylphenidate (a.k.a., Ritalin) is a schedule II drug in the United States commonly used as a psychostimulant for the treatment of attention-deficit hyperactivity disorder. It blocks dopamine and norepinephrine transporters as well as facilitates NMDA-receptor mediated synaptic transmission through σ1 receptors via PLC/PKC signaling. This interaction with the σ1 receptor has been suggested to underlie methylphenidate’s considerable abuse potential and potential psychiatric side effects. This product is intended for forensic and biological research applications.
