Summary
Methylphenidate has sympathomimetic effects that can raise blood pressure and heart rate, potentially offsetting the antihypertensive action of losartan. The effect is usually modest but can matter in patients with poorly controlled hypertension.
What this interaction means in plain words
Losartan and Methylphenidate have a small, usually unimportant interaction. Most people can take both; the pharmacist may still mention it so that any unexpected effect is recognised.
Losartan belongs to Cardiovascular; Methylphenidate belongs to Central Nervous System.
Why it happens

What to do
Check blood pressure regularly after starting or changing methylphenidate and adjust antihypertensive therapy if needed.
