What is Ritalin (methylphenidate)?
Ritalin (methylphenidate) is a drug that has the effect of stimulating the central nervous system. Its active ingredient, methylphenidate hydrochloride (methylphenidate for short), increases the levels of dopamine and noradrenaline.

Excipients are calcium phosphate, lactose, wheat starch, gelatin, magnesium stearate and talc.
