Day17 Two of today’s best-selling brands of fullstrength prescription medication for the relief of excess stomach acid，Acid-Ease and Pepticaid，are now available in milder nonprescription forms

The following appeared in an article in a consumer-products magazine：

“Two of today’s best-selling brands of full-strength prescription medication for the relief of excess stomach acid，Acid-Ease and Pepticaid，are now available in milder nonprescription forms.Doctors have written 76 million more prescriptions for full-strength Acid-Ease than for fullstrength Pepticaid.So people who need an effective but milder nonprescription medication for the relief of excess stomach acid should choose Acid-Ease.”

Discuss how well reasoned you find this argument.In your discussion be sure to analyze the line of reasoning and the use of evidence in the argument.For example，you may need to consider what questionable assumptions underlie the thinking and what alternative explanations or counterexamples might weaken the conclusion.You can also discuss what sort of evidence would strengthen or refute the argument，what changes in the argument would make it more logically sound，and what，if anything，would help you better evaluate its conclusion.

文勇五问：

（1）本题中，事实是什么？结论是什么？“Two of today’s best-selling brands of fullstrength prescription medication for the relief of excess stomach acid，Acid-Ease and Pepticaid，are now available in milder nonprescription forms.Doctors have written 76 million more prescriptions for full-strength Acid-Ease than for full-strength Pepticaid.”是事实，“So people who need an effective but milder nonprescription medication for the relief of excess stomach acid should choose Acid-Ease.”是结论，值得反驳吗？

（2）两种药物具有互换性吗？即使强效版/处方药可以，温和版/非处方药就可以吗？你能罗列出一到两个影响用药的关键因素吗？例如：适应人群，服药方式，副作用大小。

（3）76000000这个数字是多还是少？这个数字在医生的开药量中是一个明显的数字吗？文章有没有给出对比量？是否可能76000000这个数字的差距并不大？

（4）在获取方式上，处方药和非处方药之间的差异是明显的，我们能否简单地将处方药的结果套到非处方药上去？

（5）医生对某种药物更加青睐是因为这种药物更有效吗？是否可能有其他原因？你能罗列出一到两个来具体说一说吗？例如，一种药物更加廉价或是在医保报销范围内，所以消费者更容易接受；一种药物与患者的常用药之间不会产生相互影响。
