Not familiar with the industry, but I don't think the problem can be solved this way (at least in the short term). Simply by the distribution of drugs/prices, there seems to be a very large number of low cost drugs susceptible to this tactic. There's ample space for them to pick a drug now and then and put abusive prices all of a sudden, while lowering the price as soon as competition threatens to move in. Additionally, the costs of reverse engineering a drug are high enough to make this kind of competition very hard. I see no other way than some regulation to at least force some hysteresis or stability on the prices.
