消费者可以获得的药品数,这个国家同另一个国家有着很大的差别。在某些国家的市场上,可有多达30,000种专刊商标名称,而在另一些国家此类产品也许少到2,000种为了效果和价格低廉,某些公共卫生的官员曾力劝第三世界国家限制药品的生产和采购种类相对少的产品。他们建议制订一种“基本”药品名单,仅包括那些效果已经充分确定的产品,公共卫生官员正考虑要把这份名单作为一个整体来考虑,可能会适应多数世界人口的需要。 The number of medicines available to consumers varies widely from one country to another. In some countries the market may have as many as 30,000 trade names, while in other countries it may be as little as 2,000. In order to be effective and inexpensive, some public health officials have urged third world countries Limit the production of drugs and the procurement of relatively few types of products. They suggested creating a list of “essential” medicines, including only those products that have been well-established, and public health officials are thinking about taking the list as a whole and may adapt to the needs of the majority of the world’s population.
