In medical texts, you can encounter dose, dosing, dosage, dosage form, dosing unit, dosing regimen... let alone different types of doses. Let's learn how to differentiate them for accurate translation and copywriting.
💊 Dose
A dose refers to the specific quantity of a drug or medication administered to a patient at one time. This term is tied to the concept of "how much" medication is given in a single administration.
Example: "A patient is prescribed a 500 mg dose of amoxicillin to be taken twice daily."
The word dose can also act as a verb and refer to the act of administering a medication.
Example: "Always follow your health care professional's instructions on how to dose your medication."
💊 Dosage
Dosage is a broader term and refers to the overall treatment regimen or schedule, including the amount, frequency, and duration.
Example: The dosage for an adult is 250 mg orally every 8 hours or 500 mg every 12 hours.

💊 Dosing
Dosing is the act or process of administering a medication to a patient. It can refer both to how the medication is given and adherence to the prescribed regimen.
Example: The nurse ensures proper dosing by administering the medication to the patient every 12 hours as instructed.
💊 Dosage Form
A dosage form refers to the physical form in which a drug is produced and administered. Dosage forms include tablets, capsules, liquids, injections, creams, and others.
Example: Amoxicillin is available in several dosage forms, such as tablets, chewable tablets, and oral suspension.
Synonym: pharmaceutical form.
💊 Dosage Unit
A dosage unit is a pharmacopeial term, not a unit of measurement (such as mg, mL, or IU). Basically, it is a form of administration available as a single unit, such as a single pill, capsule, ampule, or a drop of liquid (reference). It is also considered to be "the typical dose taken by the patient" (reference).
Synonyms: unit dosage, unit dose.
Example: A pharmacopeial term uniformity of dosage units includes both the mass of the dosage form and the content of the active substance in the dosage form. (reference)
Note: The term "dosing unit" is not related to pharmacology. It can refer to a piece of equipment that doses a substance or mixture during manufacturing.
💊 Dosing Regimen / Dosage Regimen
A dosing regimen or dosage regimen specifies the schedule by which a medication is to be administered, including the dose, frequency, and duration.
Example: The dosing regimen is 10 mg taken orally every 4 hours as needed for pain, not to exceed 60 mg per day.
Note: The term "dosing regimen" is much more common than "dosage regimen". I advise avoiding "dosage regimen" when translating into English or writing an English text.
In the next post, we will go over different types of doses, including loading dose, maintenance dose, daily dose, and others.
