A friend said: ‘The contradiction is, a fat guy needs smaller doses but a thin chap needs higher doses’. Of course those are not necessarily true, but the point is you can’t never predict the response.

5. Perhaps this is what I would now called personalized medicine phenomena. Either it is due to slow and fast metabolizers in regard to cytochrome activities or differential tenancy of genetic make up which involved in drug metabolism and excretion.

6. We reminded ourselves to explain and caution patients and their parents before starting the medication. This is to emphasize that Methylphenidate when use with caution is safe and beneficial especially to patients with hyperactivity.

7. The objective of our meeting? Group in the making: MyCAPS – Malaysia Association of Child and Adolescent Psychiatry. Bravos.
