Calculating oral doses for children and neonates

Example: 2mg amlodipine p.o. is prescribed. 5mg amlodipine tablets are available. Crush one tablet and mix the powder thoroughly in 5ml of water.
The dose required is: (2mg x 5ml) / 5mg = 2ml
Another way of thinking about this is: 5mg in 5ml = 1mg in 1ml = 2mg in 2ml.
