Dosage calculation is usually based on working out how much medication to draw up if you have a certain concentration of medicine in the bottle and the doctor has ordered a certain dose.
For instance:
if you have to give 20mg of prednisolone syrup to a child, and the syrup comes as 5mg in 1 mL you have to perform a dosage calculation to discover that you give this child 4mL of the syrup.
You may need to perform further calculations depending on the weight of the child.
For example:
If a 10kg toddler was ordered to have 20mg per kg of paracetamol (acetaminophen), how many mL of paracetamol syrup would you give if you had the infant strength (100mg/mL) ...
and how many mL would you giv if you have the usual strength (24mg/mL) paracetamol syrup?
Here you would need to calculate the child's dosage according to his (or her) weight first - would need 200mg of paracetamol.
Then you would work out the volume to give based on the number of mg you need to give.

The dosage calculation is on the sex and weight of the person.

the formula for the drug calculation is what the dose is divided by the amount of milligrams/micrograms in the medicine bottle or tablet e.t.c mulitplied by the volume of liquid it is in.
lets say you want 125mg of penicillin and the bottle stated there was 250mg in 5mls you would want 2.5mls.
