<h3>What is drug dosage?</h3>
Drug dosage refers to the amount of drug that should be taken by a patient in order to produce effective pharmacodynamic results.
The dosage of the drug to be given is 45 mEq.
The dosage available is 30 mEq in 15 mL.
In order to give this required dosage the amount in mL required is calculated as follows:
30 mEq is in 15 mL
45 mEq will be in x mL
x = 45 * 15/30
x = 22.5 mL
In conclusion, drug dosage refers to the amount of drug required to produce good results in the patient.
