RX Japan vs. RX America


We enjoyed several lectures regarding pharmacy practice and the overall healthcare system in this wonderful country. Perhaps the most unique (and to me, the most unusual) aspect of pharmacy in Japan is the continued existence and practice of Kampo pharmacy, a type of herbal/natural medicine derived from ancient Chinese practices. Pretty much any natural material (plant, animal, mineral, etc.) that can be dried, crushed, chopped, and/or powdered is fair game for this unique type of medicinal practice. Our first day on the KGU campus, we saw several displays of jars containing different Kampo ingredients, ranging from leaves, branches and roots of many plants to pieces of geodes, mollusk shells to whole, dried seahorses! With no previous exposure to any form of herbal or homeopathic treatments under my belt, the whole concept of Kampo medicine was an entirely new world for me. As we brewed our own kakkonto for colds, I couldn’t help but wonder how effective such concoctions could really be. Of course, the origins of many of today’s pharmaceutical products lie in compounds derived from plants and other natural products, so the idea of isolating structures from the roots or leaves of different plants isn’t that exotic. What I wonder about is the purity and potency of the desired ingredients in any given dose of any given concoction. It seems to me that the extraction methods are relatively inefficient, leading to undesirably low yields of the desired compounds, with unwanted extracts (other compounds present in any given natural product) to boot. Moreover, I feel that the overall palatability of some of the mixtures is pretty limited. We were offered an energy boost on our first day at KGU, which I think contained ginseng extract in it – for me, it was completely inedible, and to be honest, the kakkonto we made as a group for colds wasn’t much better. The diagnostic approach to determining the appropriate formula to prescribe is fairly unique as well. Essentially, it involves following a flowchart of several binary divisions based on different aspects of the body and its response to illness or stress, which can ultimately result in only 8 possible conclusions. To me, it seems like an oversimplification of potentially complex disease states. Nonetheless, it’s a fascinating area, and certainly seems like it will have a stronghold in Japan for many, many years to come.
With regards to more Westernized or ‘modern’ pharmacy practice, several key distinctions can be drawn when compared to American pharmacy. Firstly, loose powders are still a common dosage form in the country, which can be extremely difficult for kids to swallow in particular. Many (if not all) pharmacies therefore have automated machines capable of dividing a measured amount of powder into uniform doses packaged into individual bags. For better ease of administration, thin sheets of a sugar polymer paper can be used to suspend a bolus of powdered drug in a goopy, gelatinous bulb, the result of a reaction between the paper and water. In general, the use of powdered drugs seems like a messy, potentially ineffective (i.e. due to spilled powder or poor dose measuring) means of administering drugs orally. What’s more, many other common dosage forms, such as oral capsules/tablets, topical ointments, etc., are sold solely in unit dose packaging. There are no large stock bottles of anything but powdered drugs or Kampo ingredients. Thus, if a pharmacy is combining multiple medications into a single dosing packet (common practice for patients who take several medications at the same time each day, which is in direct contrast to the American method of dispensing each different medication in its own labeled prescription bottle), the pharmacists must first punch out each tablet or capsule needed to fill a month’s supply for a patient, individually by hand. As such, all of the effort and material put into unit dose packaging by the drug manufacturers is essentially undone, leading to a seemingly time heavy and waste producing means of distributing drugs (in my opinion). Overall, a very different approach to drug packaging and distribution compared to the States.
Finally, the actual role of and work environment for the average pharmacist in Japan is varied in several ways. Firstly, there are no pharmacy technicians in the country – this position does not exist. All employees of a pharmacy are strictly pharmacists. Secondly, at least in the community setting (not sure about hospital), pharmacists are reimbursed based on a fairly complex formula that assigns point values to various aspects of the filling and dispensing process (1 point is worth approximately 10 yen). Thirdly, community pharmacists are limited to filling a mere 40 prescriptions per day, by law (we did not discuss hospital pharmacists in this context)! If a pharmacy is expected to consistently fill more than 40 prescriptions per day, then another pharmacist must be hired to handle the overflow. When you compare that to the 150+ prescriptions that a single pharmacist and technician can fill in an average community pharmacy on a single day, in the words of my mother, ‘it’s a wonder no one gets bored.’ This government-enforced limitation on daily dispensing, coupled with the complex and often low reimbursements derived from the reimbursement formula, result in the average pharmacist in Japan making half (or less) the average annual salary of a pharmacist in the United States. It’s rather unbelievable to me, actually. I never thought I’d prefer the often hectic, 400-per-day filling mentality found at many American community pharmacies. Although the hours and lifestyle are presumably longer and more stressful in the States, it seems the rewards are significantly greater.
Overall, I tremendously enjoyed learning the in’s and out’s of pharmacy practice in Japan, drawing parallels and distinctions between their country and ours. It was an enlightening experience, to say the least.
