 Medical history uncovers an obvious pattern in the discovery and application of drug treatments. Initially, there is great excitement about a new drug’s discovery. 

(A) Then, more research and clinical experience lead to more serious questions about the drug’s real safety and efficacy, until there is general acknowledgment that the drug doesn’t work as well as previously assumed, and there is recognition of an increasingly long list of serious side effects over time.

(B) However, these problems are not really problems because a new drug emerges, with short-term research that suggests it is a better drug after all. That is, until new research confirms that it is neither as effective nor as safe as previously thought.

(C) Research has seemingly proven its safety and efficacy and leads to widespread appreciation for the drug’s ability to provide relief. Over time, there are minor concerns about the drug’s side effects, until more research and clinical practice uncover more serious concerns about its side effects.
