The doses of the medicines can be calculated by the formula of concentration and volume. If 0.25 mg/ml solution is available then, 2000 ml of 500 mg of digoxin Elixir will be given.
What is volume?
Volume is the amount that is in indirect relation to the concentration of the substances. The volume for the dose from the concentration can be calculated by the unitary method.
Given,
Concentration of elixir = 0.25 mg
Volume = 1 mL
Concentration of the standard dose = 500 mg
The volume for the standard dose is calculated by the unitary method:
1 mL = 0.25 mg
Then, x mL = 500 mg
2000 mL of 500 mg elixir must be prepared for the standard dose.
