What is dose?

Dose refers to the amount of a substance administered to an individual, usually in terms of weight or concentration. It is a single quantity of a substance that is given to achieve a desired effect. For example, in pharmacology, the dose of a medication may be expressed in milligrams (mg) per kilogram (kg) of body weight.

Let’s look at some more examples of sentences that use dose:

  • The recommended dose of the drug is 10 mg/kg.
  • The mice were administered a single dose of the experimental compound.
  • The study found that a higher dose of the vaccine was more effective in preventing infection.

What is dosage?

Dosage refers to the regimen or schedule of administering a substance, usually over a period of time. It is the total amount of a substance given over a period, often expressed in terms of frequency and duration. For example, in clinical trials, a medication dosage may be administered once daily for a week.

Let’s look at some more examples of sentences that use dosage:

  • The recommended dosage for the medication is one tablet every six hours for a week.
  • The study compared the effects of different dosages of the supplement over a six-month period.
  • The participants were instructed to take the medication at the same dosage for the duration of the study.
