Which is the oldest system of medication measurement?

• A. Apothecary system
• B. Metric system
• C. Household system
• D. Avoirdupois system

Answer: (A)

Medicinal measurement has grown from ancient practice to standardized systems, and the oldest one used specifically for pharmacy is the apothecary system. Pharmacists in medieval Europe developed this set of units—grains for mass and minims for volume, with larger units like scruples, drams, and ounces—to meet the precise needs of compounding and dispensing medications. This system arose long before the decimalized metric system was created, and well before the everyday weight system (avoirdupois) became widespread for general use. The household system was informal and varied by region, not a formal medical measurement standard. So, the apothecary system sits earliest in the history of measuring medicines, making it the correct choice.
