Explanation of Solution

The frequency and dose of a drug is very important to maintain effective concentration in the body. A drug enters the body by a chosen route, circulates through the blood stream, and reaches the site of action. Once there, the drug shows its effects, is metabolized, and excreted from the body.

The difference between the terms “dose” and “dosage” is given below:

Dosage refers to the total amount of the drug given over a period of time. Therefore, it includes the amount of drug and time duration.

Dose refers to the amount of a drug given at a single time. Therefore, many doses would be in a dosage.
