The size refers to fluid drams (8 fluid drams to 1 fluid ounce) , not solid drams---it refers to the volume of the vial. In my day, we'd simply estimate the size of the vial vs. the size of the tablet, but I suspect today's technology would suggest a vial size based on the tablet size, sothe pharmacist or pharmacy technician can merely reach for the size suggested on the label printout. Coo-ool.
Next time you get an oral solution (such as cough syrup) dispensed to you by prescription, look at the back or side of the brown bottle. You will see the ancient apothecary symbol for fluid ounce, "℥," followed by a Roman numeral. So, an eight fluid ounce bottle reads ℥ viii. Why are these currently used pharmacy products still using apothecary units, which were deprecated by the United States Pharmacopeia (USP) in 1995? Refer to "Fiddler On The Roof": TRADITION! Also because the container manufacturers have never been required to eliminate them. It might be expensive to change the machinery that impresses the "℥ viii" instead of "240 mL," but I think times change. This is an important point, not only about metrication, which would require these containers to be denominated in milliliters only, but for consistency in medication safety. How are we going to get the U.S. public to "think milliliter" with regard to measuring oral liquids if we continue to show medication container sizes in legacy units of measurement? Part of the answer is that there are milliliter and fluid ounce scales on the brown bottles, and it is high time that the apothecary sizes, and fluid ounce scale be eliminated and milliliters only shown. The USP metric-only standard for drugs should apply across the board. I am sending a copy of this message to the Institute for Safe Medication Practices (ISMP) to see what is being pondered by that organization. ISMP has recommended the elimination of household measurement from healthcare at all levels, and these containers, which are designed exclusively for use in pharmacy, ought to be considered as well. If the teaspoonful and the tablespoonful are to be deprecated, then other non-metric measurement units should be thrown out as well. As far as extending metrication of healthcare in the U.S. is concerned, revamping these old-style containers are where part of the rubber meets the road.
